Interesting Planet Pairing for 2009

  • December 31, 2008 - Jupiter and Mercury - After sunset a little more than one degree apart in Sagittarius. Pull out the binos and telescopes because Mercury will be a mere 15 arcminutes from the globular cluster M75. All three will be together in one field of view in most home binoculars.
  • January 22nd - Venus and Uranus - After sunset 1.3 degrees apart a few days later on the 29th they are joined by a waxing crescent moon.
  • February 23rd - Jupiter, Mars and Mercury - In the early morning sky just before sunrise the trio are in a space about 2 degrees wide. Binoculars will be helpful but beware the quickly rising Sun. The Moon, almost invisible, will be between Mars and the Sun.
  • March 23rd - Mars, Moon, Neptune, and Jupiter - Makes a nice line-up in the morning sky with Neptune just off the tip of the waning crescent moon.
  • April 21st - Venus, Mars, Uranus, waning crescent Moon, Neptune and Jupiter - all in the pre-dawn sky together. First the right triangle of Venus, Mars, and Uranus followed by the waning crescent Moon and then finally by Neptune and Jupiter. Mars will be a faint 1.41 mag so binoculars will be helpful. The next day, possible occultation of Venus by the Moon. Check the IOTA website for occultations in your area.
  • May 25th - Jupiter and Neptune - Jupiter is less than 1/2 degree South of Neptune in the morning sky. If you have ever had problems finding Neptune this would be a good time to try, between now and June.
  • June 19th - Venus and Mars - In the pre-dawn sky just south of a waning crescent Moon. Closer to the Sun is Mercury and the Pleiades.
  • August 17th - Saturn and Mercury - Very close to the Sun low in the evening sky. Much better view for Southern viewers.
  • September 3rd UT 4:43 - Jupiter hides its Galilean moons. Not until 2019 will all of Jupiter's Galilean moons orbit in such a way.
  • September 4th - Saturn - Not exactly a pairing but the Earth will cross the plane of the rings from south to north making the rings invisible
  • October 16th - Mercury, Venus, and Saturn - All lined up in the pre-dawn sky close to the horizon. A faint waning crescent is just south of the trio.
  • December 24th - Jupiter and Neptune - Just after sunset Jupiter and Neptune sit side-by-side just north of delta Capricornus and east of the "42,44,45 Cap Wall"

[ Lunar: Penumbral ]

 

January 26 - Annular Solar Eclipse ( see map, times, and animation!): The first solar eclipse of 2009 occurs at the Moon's ascending node in western Capricornus. An annular eclipse will be visible from a wide track that traverses the Indian Ocean and western Indonesia. A partial eclipse will be seen within the much larger path of the Moon's penumbral shadow, which includes the southern third of Africa, Madagascar, Australia except Tasmania, southeast India, Southeast Asia and Indonesia.

 

February 09 - Penumbral Lunar Eclipse ( see map, times): The first lunar eclipse of 2009 is one of four such events during the year. The first three eclipses are penumbral while the last (on Dec. 31) is partial. The Feb 09 event is the deepest penumbral eclipse of the year with a penumbral magnitude of 0.899. It will be easily visible to the naked eye as a dusky shading in the northern half of the Moon. The times of the major phases are listed below.

July 07 - Penumbral Lunar Eclipse ( see map, times.): July's penumbral eclipse is only of academic interest since the magnitude is just 0.156. Although the Moon will be above the horizon from most of Canada, the eclipse is so minor as to be completely invisible to the naked eye.

July 21-22 - Total Solar Eclipse ( see map, times, and animation!): To make up for the anemic lunar eclipse earlier in the month, a major total eclipse of the Sun occurs two weeks later. The path of the Moon's umbral shadow extends across India, China, a handful of Japanese islands and the South Pacific Ocean (Espenak and Anderson, 2008). A partial eclipse is seen within the much broader path of the Moon's penumbral shadow, which includes most of eastern Asia, Indonesia, and the Pacific Ocean.

August 05-06 - Penumbral Lunar Eclipse ( see map, times): A shallow penumbral eclipse occurs 15 days after the total solar eclipse. Since its magnitude is only 0.402, it will not be visible to the naked eye.

December 31 - Penumbral Lunar Eclipse ( see map, times): The last eclipse of 2009 occurs on New Year's Eve. This minor partial lunar eclipse takes place in Gemini, and is visible primarily from the Eastern Hemisphere (Figure 8). Greatest eclipse takes place at 19:23 UT when the eclipse magnitude will reach 0.0763.

Explanation of the 2009 Meteor Shower Calendar

Shower: named for the constellation or closest star within a constellation where the radiant is located at maximum activity.

Activity Period: the dates when the ZHR (Zenith Hourly Rates) are equal to or greater than one.

Maximum: the date on which the maximum activity is expected to occur.

S.L.: the equivalent solar longitude of the date of maximum activity. Solar longitude is measured in degrees (0-359) with 0 occurring at the exact moment of the spring equinox, 90 at the summer solstice, 180 at the autumnal equinox, and 270 at the winter solstice.

Radiant: the area in the sky where shower meteors seem to appear from. This position is given in right ascension (celestial longitude) and declination (celestial latitude).

Velocity: the velocity at which shower meteors strike the Earth's atmosphere. The velocity depends on the angle meteoroids (meteors in space) intersect the Earth. Meteoroids orbiting in the opposite direction of the Earth and striking the atmosphere head-on are much faster than those orbiting in the same direction as the Earth. This velocity is measured in kilometers per second.

r: The Population Index, An estimate of the ratio of the number of meteors in subsequent magnitude classes. Simply stated: the lower the "r" value, the resulting overall mean magnitude of each shower will be brighter. "r" usually ranges from 2.0 (bright) to 3.5 (faint).

ZHR: Zenith Hourly Rate, the average maximum number of shower meteors visible per hour if the radiant is located exactly overhead and the limiting magnitude equals +6.5. Actual counts rarely reach this figure as the zenith angle of the radiant is usually less and the limiting magnitude is usually lower. ZHR is a useful tool when comparing the actual observed rates between individual observers as it sets observing conditions for all to the same standards.

Class: A scale developed by Robert Lunsford to group meteor showers by their intensity:

Class I: the strongest annual showers with ZHR's normally ten or better.

Class II: reliable minor showers with ZHR's normally three or better.

Class III: showers with widely variable rates. They may be strong one year and totally inactive the next.

Class IV: weak minor showers with ZHR's rarely exceeding three. The study of these showers is best left to experienced observers who use plotting and angular velocity estimates to determine shower association. Observers with less experience are urged to limit their shower associations to showers with a rating of I to III. These showers are also good targets for video and photographic work.

Moon: the age of the moon in days where 0 is new, 7 is first quarter, 14 is full, and 21 is last quarter. Meteor activity is best seen in the absence of moonlight so showers reaching maximum activity when the moon is less than 10 days old or more than 25 are much more favorably observed than those situated closer to the full moon.

Carpe Noctem - Seize the Night!

An amateur's reflection of the AAS conference.....(Mira B news was fun!)

When I Heard the Learn'd Astronomer

When I heard the learn'd astronomer,
When the proofs, the figures, were ranged in columns before me,
When I was shown the charts and diagrams, to add, divide, and measure them,
When I sitting heard the astronomer where he lectured with much applause in the lecture-room,
How soon unaccountable I became tired, and sick,
Till rising and gliding out I wander'd off by myself,
In the mystical moist night-air, and from time to time,
Look'd up in perfect silence at the stars.

Walt Whitman, 1865 (TOAOAL-II, PP 821-822)

Listener Feedback

Lots of great email out there with folk sharing their new astronomical acquisitions. This is a familiar scene:


Congratulations Dan!

I had my own great surprise! Can you guess what it is? (click on the picture for the answer) Many thanks to the entire Harris Family!



Observing Lists

Ben 34, NGC 1904, M79...a rose by any other name....listed in order of creator's birth...

Abbe Nicholas Louis de la Caille (Lac), French deacon and astronomer (1713-1762) This catalog was compiled during his 2-year journey to the Cape of Good Hope in 1751-52, "Catalog of Nebulae of the Southern Sky"(list)

Charles Messier (M), French astronomer (1730 - 1817) Between 1758 to 1782 compiled a list of 'non-comet' items. The SEDS (Students for the Exploration and Development of Space) site is one of the best resources for Messier Objects. (list. Messier compiled his list of deep sky objects in three parts; "Memoires de l'Academie" 1774, "Connoissance des Temps" 1780, and "Connoissance des Temps" 1781.

Pierre Francois Andre Mechain , French astronomer (1744-1804) co-worker with Charles Messier at at the small observatory at Hotel de Cluny in Paris. Mechain contributed many object to the 'Messier' catalogue and has may other objects an comets to his credit. (list)

Wilhelm (William) Herschel (H) , (1738-1822) was a German-born British astronomer and composer who became famous for discovering the planet Uranus. Herschel published "Catalogue of One Thousand new Nebulae and Clusters of Stars" in 1786 and "Catalogue of a second Thousand of new Nebulae and Clusters of Stars; with a few introductory Remarks on the Construction of the Heavens" in 1789 500 more objects were added to complete the 2500 Herschel Objects (list)the Astronomical League has an award for observing 400 of the Herschel Objects.

Johann Elert Bode, German astronomer (1747-1826) Bode was the director of the Berlin Observatory, where he published the Uranographia in 1801 that combined the artistic with the scientific. All amateurs should appreciate that he published a small atlas for amateurs called "Vorstellung der Gestirne" which looked at constellations and their mythologies. "Complete Catalog of Nebulous Stars and Star Clusters", Astronomisches Jahrbuch for 1779, Berlin (1977) (list)

Caroline Herschel (CH), German born English astronomer (1750-1848) was an avid astronomical observer, discoverer of comets (she originally found 8 of them) and deepsky objects (list) collected from 1783-87 which are included in William Herschel's catalogue.

John Herschel (h), (1792-1871 son of William Herschel) English born In 1833 Herschel traveled to South Africa in order to catalogue the stars, nebulae, and other objects of the southern skies. This was to be a completion as well as extension of the survey of the northern heavens undertaken initially by his father.

James Dunlop (Dunlop), Scottish born Australian Astronomer (1793-1848), James Dunlop's Catalog of southern Deep Sky Objects, compiled 1823-27 "A Catalogue of Nebulae and Clusters of Stars in the Southern Hemisphere observed in New South Wales" (list)

the SEDS site has a highlight list

John Louis Emile Dreyer (NGC, IC), (1852-1926) was a Danish-Irish astronomer. He worked with Lord Rosse at Birr where the giant six-foot Leviathan, at that time the largest telescope in the world, was at his disposal. His major contribution was the monumental "New General Catalogue of Nebulae and Clusters of Stars" (NGC), whose catalogue numbers are still in wide use today, as well as two supplementary Index Catalogues (IC); "Index Catalogue of Nebulae Found in the Years 1888 to 1894". (list)

Jack Bennett (Ben), (1914-1990) South African astronomer drew up two lists of southern objects that appeared comet-like in his telescope. His first list (Bennett, 1969) was published four months before he discovered his first comet. The supplementary list (Bennett, 1974) was followed three months later by his second discovery. Bennett's list reads like the "Who's Who of the Deepsky" and provides Southern observers will an extension to more northern lists. (list)

Sir Patrick Moore and the Editors of Sky & Telescope created "The Caldwell Catalog: 109 Deep-Sky Delights for Backyard Observers" The Royal Astronomical Society of Canada (RASC) has published several useful observing lists in their yearly Observer's Handbook, edited by Roy L. Bishop:
The Astronomical League has provided extra observing tours beyond the Messier objects for binocular observers, each one for Northern and Southern Deep Sky Objects
The Hawaiian Astronomical Society keeps a list of lists, so to speak.
Astronomical Society of South Africa has a nice set of 100 deep sky objects
...plus many more.

Sun

Planets

Evening Planets
  • Mercury - Mag -1.1 in Sagittarius lost in the glare heading for the night time sky.
  • Venus - Mag -3.8 in Capricorn sitting low on the horizon at sunset - spectacular!
  • Neptune - Mag +8.0 in Capricorn less than 1 degree north of the +4.3 magnitude star Iota Capricorni
  • Uranus - Mag +5.9 in Aquarius Uranus under 1 degree east of Lambda Aquarii.
  • Saturn - Mag +0.2 on the western edge of Leo just west of Regulus. An easy catch and now rising earlier in the evening!


Morning Planets
  • Jupiter - Mag -1.7 in Ophiuchus visible on the ESE horizon an hour before sunrise.
  • Mars - Mag 1.5 in Sagittarius just above the Sun's glare but visible between Jupiter and the horizon.

Constellations

Lepus - the Hare - one of the animals presumed to be hunted by Orion it is more likely that the poor hare was just startled from his burrow by the great hunter charging Taurus the bull.
Invented/listed by: Ptolemy
Deep Sky objects:NGC 2017 open cluster binoculars and small telescopes reveal five stars building a multiple star system
NGC 1904 (M79) globular cluster (7.7 mag)is quite compact and a good object for small telescopes
IC 418 "Raspberry Nebula" planetary nebula (9.3 mag) between Rigel and alpha Leporis, looks likes a 9th mag "star"
Double stars: gamma Lep is a duo of a yellow and a red star with 4th mag and 6th mag, respectively. Its an attractive pair for binoculars.
Herschel 3752 is a nice triple star visible in small telescopes same field of view as M79
Variable stars: R Lep is a long-period variable of a deep red color. It is also known as Hind's Crimson Star is described as a drop of blood on a black surface. The brightness varies from 6th mag to 10th mag about every 430 days.

Carpe Noctem - Seize the Night! Week of Oct. 31, 2006

The Starlight Night

LOOK at the stars! look, look up at the skies!
O look at all the fire-folk sitting in the air!
The bright boroughs, the circle-citadels there!
Down in dim woods the diamond delves! the elves'-eyes!
The grey lawns cold where gold, where quickgold lies!
Wind-beat whitebeam! airy abeles set on a flare!
Flake-doves sent floating forth at a farmyard scare!
Ah well! it is all a purchase, all is a prize.

Gerard Manley Hopkins (1844-1889)

Planets

Evening Planets
  • Mercury - Mag 0.0 in Libra. Mark your calendars for inferior conjunction and visible transit on Nov. 8th! Low on the western horizon near Jupiter.
  • Jupiter - Mag -1.6 in Libra. Visible low in the sky just after sunset.



    images courtesy of: Stellarium software
  • Pluto - Mag +14.0 in Ophiuchus
  • Uranus - Mag +5.8 in Aquarius Uranus is best seen in a dark moonless sky away from artificial lighting. It may be seen looking like a very faint star to the dark-adapted naked eye that shimmers in and out of visibility just over 1 degree east of Lambda Aquarii. Find the tipped over letter Y of Aquarius, go 4 thumbwidths southeast to find Lambda, and then look pinky nail east.
  • Neptune - Mag +7.9 in Capricorn 1.25 degree north of the +4.3 magnitude star Iota Capricorni


Too close to the sun..
  • Mars - Mag +1.6 is at the western end of Virgo and lost in the sun in the northern latitudes. You will have to look hard in the haze of the horizon and it will help to be closer to the equator.
  • Venus - Mag -3.8 in Virgo.
Morning Planets
  • Saturn - Mag +0.6 on the western edge of Leo!
Shall we be sassy? Dwarf Planets..er...Minor Planets...er...Icy Dwarfs....er...um...hmmmm
  • 1 Ceres +7.9 mag in Pisces Australis 18.5 degrees West of Fomalhaut
  • Eris mag +19 in central Cetus

Constellations



Horologium -the pendulum clock - Horologium was named by Abbe' Nicolas Louis de Lacaille. Originally named Horologium Oscillitorium to honor Christian Huygens, the inventor of the pendulum clock in 1656-57 but like most longer astronomical names it was shortened to Horologium . Huygens is also famous for discovering Saturn's rings.

Reticulum - the grid - A reticle consists of sets of parallel and perpendicular lines, either in the form of thread or wire or in the form of markings etched in glass. The result is a square grid which may be accurately used to locate and plot the relative positions of objects viewed through the grid. Zeta Reticuli is a double star visible to the naked eye and strangely enough the home of the aliens in the alleged Barney and Betty Hill abduction.

Aries - the ram - One of the 48 constellations listed by Ptolemy and one of the 13 zodiacal constellations In Greek mythology Athamas, the king of Orchomenos, was married first to the goddess Nephele with whom he had the twins Phrixus and Helle. He later divorced Nephele and married Ino, daughter of Cadmus. Phrixus and Helle were hated by their stepmother, Ino who hatched a plot to get rid of the twins, roasting all the town's crop seeds so they would not grow. The local farmers, frightened of famine, asked a nearby oracle for assistance. Ino bribed the men sent to the oracle to lie and tell the others that the oracle required the sacrifice of Phrixus. Athamus reluctantly agreed. Before he was killed, though, Phrixus and Helle were rescued by a flying golden ram sent by Nephele, their natural mother. Helle fell off the ram into the the strait between the Aegean and the Sea of Marmara (Hellespont which was named after her) and died, but Phrixus survived all the way to Colchis (kolkis), where King Aettees took him in and treated him kindly, giving Phrixus his daughter Medea in marriage. In gratitude, Phrixus gave the king the golden fleece of the ram, which Aettees hung in a tree in his kingdom.

Top 10 Astronomy misconceptions

""Be very, very careful what you put into that head,
because you will never, ever get it out.

Thomas Cardinal Wolsey (1471-1530)

  1. Bad! The Big Dipper is a constellation (and the Pleiades is the same thing as the Little Dipper)
    Good! The Pleiades and the Big Dipper are asterisms.
  2. Bad! You can (only) balance an egg on the equinox.
    Good! If you have steady hands you can balance an egg anytime!
  3. Bad! The seasons are caused by our distance from the sun.
    Good! The seasons are the result of the tilt of the Earth!
  4. Bad! The Coriolis effect causes drains and toilets to rotate in different directions in different hemispheres.
    Good! Check out this website: http://www.ems.psu.edu/~fraser/Bad/BadCoriolis.html
  5. Bad! August Mars will be as big as the full moon. This was a horrible email full of erroneous facts.
    Good! Track the relationship with Earth and Mars on this website to see when we are close(er) to Mars.
  6. Bad! The moon looks larger on the horizon because the air is thicker and acts like a magnifying glass.
    Good! Look at the illusions here: http://www.lhup.edu/~DSIMANEK/3d/moonillu.htm
  7. Bad! The "dark side of the moon" never receives any sun-light.
    Good! Try it! Since the moon rotates on its axis it will receive sunlight on all sides.
  8. Bad! Polaris is the brightest star in the sky.
    Good! The sun is the brightest star followed my Sirius, Canopus, Rigel Kentaurus, etc
  9. Bad!Bad! First man in space was John Glenn.
    Good! Yuri Gagarin was the first human in space.
  10. Bad! You can buy a star or a piece of the moon.

AAGG Show #13: Show Notes

Carpe Noctem - Seize the Night!

Canis Major The great Overdog That heavenly beast With a star in one eye Gives a leap in the east. He dances upright All the way to the west And never once drops On his forefeet to rest. I'm a poor underdog, But to-night I will bark With the great Overdog That romps through the dark. -- Robert Frost

Welcome!

Welcome to Brian from Minnesota, Dave from Alabama and Pat from Montreal and thank you for the email.

Hello to Bill from Missouri who sent me a very nice note and also hello to his son who will be starting his Astronomy Merit badge soon! Remember, if it is a nice night out then you have an excuse to go outside and stay up late...as long an you are learning those constellations....and your homework is done!

Tips and Tricks - Time!

"Tiiiiiiime is not on my side...no siree!"

Local Apparent Time (LAT), also called apparent solar time or sundial time. Noon was what most people still think is noon: when the Sun crosses the meridian or the highest point in its path.

Your Local Mean Time (LMT) Astronomers created an imaginary, "averaged" Sun that travels along the celestial equator. Differs from your standard civil (clock) time by many minutes. The correction depends on how far you live east or west from the center of your time zone.

Standard time. Time zones are standardized on certain longitudes: 75 degrees W for Eastern Standard Time, 90 degrees for Central, 105 degrees for Mountain, and 120 degrees for Pacific. For every degree you are east of your time zone's standard longitude, add four minutes to standard time to get LMT. For each degree you are west, subtract four minutes. The number of minutes the real Sun lags behind or runs ahead of the mean Sun was named the equation of time.

Summer-time To obtain daylight saving time ("summer time"), subtract one hour from standard time.

Universal Time (UT). Standard time (and its daylight-saving variant) serves fine within a given time zone. But when a time applies worldwide, such as in an astronomical almanac, you need one reference point. Logically enough, the "universal" time zone that was agreed upon (in 1884) is that of 0 degrees longitude. This longitude is, by definition, that of a line engraved in a brass plate in the floor of the Old Royal Observatory at Greenwich, England. UT is often called.....

Greenwich Mean Time (GMT). Greenwich Mean Time" or UT1, until the popular meaning drifted to match UTC. Astronomers now try to avoid the term altogether unless they are waxing nostalgic. Adding to the confusion, GMT began the day at noon, not midnight. .

Coordinated Universal Time or UTC, Since 1967 the second has been defined as how long cesium-133 atoms take to emit 9,192,631,770 cycles of a certain microwave radiation in an atomic clock. To keep our clocks in close step with the turning of the Earth, a leap second is inserted into Universal Time when required - about once a year on average. A leap second may be added at the end of June 30th or December 31st UT, giving the last minute of the chosen day 61 seconds.

The result is the system by which all the world's clocks are set. UTC is the basis for all time-signal radio broadcasts and other time services.

Civil twilight - when the Sun's center is 6° below the horizon the brightest stars are visible and at sea the horizon is clearly defined.

Nautical twilight - when the Sun's center is 12 degrees below the horizon this would be the "dark" to obey in the mother's order to "be home before dark"! For nautical purposes it is that time when the horizon ceases to be clearly visible and it is impossible to determine altitudes with reference to the horizon.

Astronomical twilight - when the Sun's center is 18 degrees below the horizon and there is no sun glow left at all.

John Harrison (March 24, 1693 - March 24, 1776) an English clock maker, who designed and built the world's first successful maritime clock, one whose accuracy was great enough to allow the determination of longitude over long distances.

Sky and Telescope article on Time

Planets

Venus - just before dawn between Aquila and Sagittarius
Jupiter - in the wee hours of the morning in the constellation Libra. On the 5th of this month it stopped moving across the sky relative to the background stars and began its westward motion or retrogradation.
Go check out the finder forTransit of the Great Red Spot and a JAVA script to help you find Jupiter's moons
Saturn - is in Cancer the crab and come summer we should see that planet slow down and turn around as well.
Mars - in Taurus between Aldeberon and the Pleiades and speeding right along

Naked eye viewing- Moon is a waxing gibbous and becomes full on the 14th (don't forget the penumbral eclipse!) Mare Frigoris is the long narrow strip of a sea across the lunar N.Pole
Right below Frigoris is Mare Imbrium (IM-bree-um - Sea of Rains) the second largest sea.
Craters Kepler and Copernicus run along just above the equator (I"m trying to create a picture so check back soon!)
and Mare Insularum(Sea of Islands) and Mare Nubium (NEW-bee-um)run below Copernicus.

AAGG Show #10: Show Notes

Carpe Amor - Seize the Love!

"i carry your heart"
by ee cummings

i carry your heart with me (i carry it in
my heart) i am never without it (anywhere
i go you go, my dear; and whatever is done
by only me is your doing, my darling)

i fear
no fate (for you are my fate, my sweet) i want
no world (for beautiful you are my world, my true)
and it's you are whatever a moon has always meant
and whatever a sun will always sing is you

here is the deepest secret nobody knows
(here is the root of the root and the bud of the bud
and the sky of the sky of a tree called life; which grows
higher than soul can hope or mind can hide)
and this is the wonder that's keeping the stars apart

i carry your heart (i carry it in my heart)

Welcome!

Hello to Frank in Toronto he has a new scope and is floating on that new scope high!

Welcome to Ed from the Birmingham Astronomical Society in Birmingham Alabama. This club has a very nice webpage if you are looking for an example of a well laid out club page. I happen to be partial to ours as well! Ed did you know that there is a Birmingham Astronomical Society in the United Kingdom?

Lastly a special Howdy to my sister Kellie and her husband Craig and their boys. The final song in the show is for my nephews...Caleb and Ben when you are done looking at the stars put on the p.j.s and listen to the song... it is time for bed!

Tips and Tricks

We have been easing into astronomy and astronomical skills and I have a new skill for you to roughly gauge distances in the sky.

Held at arm's length, your pinky finger is about 1 degree wide. Your three middle fingers, held together, are about 5 degrees wide. If you hold out your fist, it will measure a 10 degree width of the sky. If you hold up just your pointer finger and your pinky finger, it will be about 15 degrees of sky between them. If you spread the thumb and pinky of one hand as far apart as they will go, it will be about 25 degrees from outside edge to outside edge.

Now this is an approximate measuring device of course but it works very well. So now I can go out and say that Saturn is 15 degrees SE of Pollux (of Castor and Pollux in Gemini)

Special Valentines Gift

In show #3 we talked about planispheres and how to use them. Planisphere are a wonderful tool and for the N. Hemisphere there are many that you can find for free online. Alas for the southern hemisphere I couldn't find one decent FREE planisphere. Chris, from the Astronomy in your hands website, is giving Astronomy a Go Go! podcast listeners a free planisphere! It is the city version but after looking at his site if you like the Milky Way version you can subscribe and get them all.

In order to make sure that folks don't just randomly find and pilfer these gifts I have hidden them on the show notes! For If you listened you will know what to do...(look at the bottom of the page)

Constellations

For most amateur astronomers constellations are shapes and containers that help us find other things that we really want to see like comets, double stars, and Messier objects. We have been working our way through the 88 'official' constellations since January and tonight we add 3 more all of which are tough!

  • Lepus, the Hare. Only 4 bright stars from our city location and home to M79 is a beautiful globular cluster.
  • Monoceros (mon-OSS-err-us), The Unicorn. Almost visible in the urban lights an home to M50 and open cluster.
  • Columba, Noah's Dove. The constellation refers to the dove released several times during the voyage after the great flood to find land, it was this dove that returned with an olive branch in its beak, indicating dry land had been found.


Northern Hemisphere looking South


Equator, looking West and up


Southern Hemisphere looking North and up

Naked eye viewing- There are always celestial clues that time is just whizzing by. Not nearly as critical as the flooding of the Nile, when I start to seen Arcturus, the 4th brightest star in the night sky and the brightest star in the constellation Bootes, in my window at bed-time I know that it won't be long until the early summer (or winter in the S.H. )constellation will be visible.

But our naked eye challenge tonight is to find the Pleiades. They are in the constellation Taurus the Bull and near Mars. I have Mars marked in each of the charts on the show notes. The Pleiades, or M45 look to me like a very small cup with a short pokey handle. Just how many stars can you see. They are called the 7 sisters but this open cluster has hundreds of stars. I hope your vision is better than mine!

Binocular viewing- We are going to look back at the moon tonight and find the bright crater Copernicus

Named after the Polish astronomer who in 1543 gave us the first modern formulation of a heliocentric (Sun-centered) theory of the solar system. You can see it with the naked eye but with your binoculars you should be able to see the high walls and if you look north and east you will find another large crater Eratosthenes (aira TOTH tha nees) named after the Greek mathematician who is noted for devising a system of latitude and longitude, and for being the first known to have computed the size of the Earth.

Telescopic viewing- If you have a telescope lets look for those Messier objects we talked about earlier. M79 and M50...you will be helping me get ready for next months marathon!

News

Cassini listens as well as looks! So if you think that Cassini is only taking fabulous pictures listen to this. The Cassini spacecraft has captured radio emissions believed to come from a large lightning storm on Saturn.

This image shows a rare and powerful storm on the night side of Saturn.

Light from Saturn's rings (called "ringshine") provided the illumination, allowing the storm and other cloud features to be seen. This storm is approx 2,175 miles north to south which is the distance from Seattle Washington to Dallas Texas

Space Station Flies in Higher Orbit The International Space Station (ISS) is in a higher orbit after a weekend boost from one of two unmanned cargo ships docked at the orbital platform. The maneuver will help place the ISS in position for the arrival of ISS Expedition 13 Russian ISS flight controllers said the reboost maneuver, which occurred at 5:20 p.m. EST (2020 GMT) on Feb. 11, also allowed them to test techniques to dodge space debris in orbit, according to the Interfax News Agency.

Part of a solar system running in reverse?

In a NASA news release from Monday reports that NASA scientists have discovered a solar system with planets rotating to two different direction. Our solar system is a one-way boulevard. All the planets --- from Mercury out to Pluto and even the newly discovered objects beyond --- revolve around the Sun in the same direction. The fact that a solar system can have planets running in opposite directions is a shocker.

This solar system, about 500 light-years from Earth in the direction of the constellation Ophiuchus, is a work in progress. At its center is a young star. No planets have formed yet and likely won't for millions of years. What Remijan and Hollis saw were two flat and dusty disks rotating around the equatorial plane of the central star in opposite directions.
A paper describing this result will appear in the April 1 edition of the Astrophysical Journal.

AAGG Show #5: Show Notes

Welcomes

Welcome to Joe from Middlefield, Connecticut at 41.5 degrees N and Jeremy from Bristol England at 51.4 degrees N. Jeremy is a member of the Bristol Astronomical Society and was kind enough to pass along their website. It is a good website so go take a look.

As always you can email us at astronomyagogo@gmail.com or leave a note in our show notes at www.astronomy.libsyn.com. We would love to hear from you!

Tips and Tricks

We have a special award tonight, the first GoGo! Award goes to Damon in NE Texas. Damon and I have been talking offline about binocular viewing and how to keep the binoculars steady.

What ever binoculars you have right now are the best ones to start viewing with! Leaning against a wall or post, propping your elbows on the top, trunk or boot of the car are fast and easy ways to steady yourself but eventually you will want to incorporate some tools to help especially if you plan on sharing what you see with others. In a pinch you can put the binos on a regular camera tripod.

I have some links on the show note for instructions for mounting binos to tripods and for building your own binocular mounts. I love the parallelogram style mounts because they allow me to set the binoculars up on an object and then lower the binos to a child's level while keeping everything centered. Look ma no hands! Damon is off to build a set which is why he gets tonight's GoGo! Award.

Stargazing tips

There is nothing better than being out under a dark clear sky with thousands of stars above your head. Here are a few tips to make your sky viewing as comfortable and successful as possible

  • Dress for the weather. You will not be moving much so it will be colder. If you dress in layers you can add clothes and take them off as needed. Put as much between you and the ground as possible. I use an old Girl Scout sit-upon to insulate myself from the ground or the chair and thick boots to insulate myself from the ground. Many people bring old pieces of carpet to stand on. Hats scarves and gloves should be carried in abundance.
  • Find the darkest site you can. Sometimes we can't leave the house so make the space you are in as dark as you can. Turn off all the house lights and ask your neighbors to do the same. The side of the house may give you a narrow view but if it is dark that is okay, work on the stars in that area.
  • Be a good Scout. Let people know where you are going and when you'll be back. If you are going to a remote site alone make sure you have a way to handle emergencies, like a dead battery. A cell phone and a 'flight plan' works here. Always make sure you leave the site better than you found it.
  • If you travel out to a site try to get there before dark. It helps to get oriented and everything set up and finding the bathroom. Then you can sit back and have a nice cup of tea or a latte and relax and review your star charts in leisure while everyone else scurries around.
  • Pay attention to your eyes! Keep your eyes dark adapted, avoid looking at lights, cover your eyes when cars come by, put on sunglasses if you need to go inside. The longer your eyes are in the dark the better you can see the faint objects in the sky.
  • Have several red flashlights and hide the while light. Make sure you know how to turn off your headlights so they don't come on when you start the car and if you can find clear red plastic report covers they are wonderful for masking flashlight. It gives you a nice dark red use it to cover the interior car lights too.
  • Pack for comfort. Think about your environment, are there mosquitoes, do you have a way to sit and look up (for hours) comfortable, wind?, a little table to put your stuff on? Food and drink? Music and your favorite astronomy podcasts to listen to? Bring foods that will keep you warm in the winter and include lots of water, it is better for your vision to keep your whole system hydrated.
  • Have a plan for your viewing, it could be just to relax and look around but if you have something in particular make sure you have your planisphere and have done a little research before you go. Also have a Plan B!
  • Take what you have. If you don't have a telescope that's fine! Take just yourself, or take some binoculars. The Pleiades, in the constellation Taurus, are better in binoculars than in a telescope. There is lots to see in binoculars.
  • Once you feel like you are ready to buy a telescope, stop! Visit or join an astronomy club instead and play with all of their telescopes first. Give yourself time to discover what kind of astronomer you are likely to be and who you are doing this with.

Constellations for Show #5

 " Arthur's slow wain (wagon) his course doth roll,
    In utter darkness round the pole;
    The Northern Bear lowers black and grim;
    Orion's studded belt is dim;
    Twinkling faint, and distant far,
    Shimmers through mist each planet star,
    Ill may I read their high decree!"

    Sir Walter Scott, 1805, 
	'The Lay of the Last Minstrel', 
	Canto First, Verse XVII.

  • Ursa Major, big bear
  • Ursa Minor, little bear
  • Draco, the drago
  • Crux, the cross
  • Musca, the fly
  • Octans, the octant

Planets

Mars is still easy to pick out as the rusty red point west of the Pleiades and above the tale of Cetus the whale.
Saturn sits in Cancer and outshines all the stars in that constellation. Start at Gemini the twins and move east to the yellow large point of light.
There is a great article on the Planetary website with several Cassini frames stitched together to animate the movement on the rings and the moons http://www.planetary.org/blog/article/00000342/ Jupiter is east of Virgo in the constellation Libra in the early morning hours.

Next week we will start our weekly investigation into the planets starting with Mars.

News

After a remarkable 13-year voyage of discovery, TOPEX/Poseidon, the first great oceanographic research vessel to sail into space, ended its mission this month.

In a cosmic version of laser tag, NASA's MESSENGER spacecraft and an Earth-based observatory successfully exchanged laser pulses with each other while millions of miles apart.

Polaris. (NASA news) The North Star is thought to be a steady, solitary point of light that guided sailors for ages, but there is more to this star than meets the eye. The North Star is actually a triple star system.

Rovers The most recent self-portrait of NASA's Mars Exploration Rover Spirit shows the solar panels still gleaming in the martian sunlight and carrying only a thin veneer of dust.

Of the nine recognized major planets in our solar system, Pluto alone remains unvisited by a man-made craft. New Horizons, the first of NASA's "New Frontiers" missions, was selected by NASA to fill this gaping hole in the exploration of our own solar system. Scheduled to launch January 17, 2006, New Horizons' journey will last at least 9 years and possibly as long as 15 years.

NASA'S HUBBLE REVEALS THOUSANDS OF ORION NEBULA STARS

"Orion is a bustling cauldron of activity. This new large-scale Hubble image of the region reveals a treasure-house of beauty and astonishing detail for comprehensive scientific study," said Jennifer Wiseman, NASA's Hubble program scientist.

NASA'S SPITZER FINDS POSSIBLE COMET DUST AROUND DEAD STAR

The Spitzer space telescope in an infared telescope that was launched in August of 2003.

NASA's Spitzer Space Telescope spotted what may be comet dust sprinkled around the white dwarf star G29-38 that died approximately 500 million years ago.

"Astronomers have known for decades that stars are born, have an extended middle age, and then wither away or explode. Spitzer is helping us understand how planetary systems evolve in tandem with their parent stars," said David Leisawitz, NASA's Spitzer program scientist.

Stardust Interview

Re-entry of Stardust If you live in the Northern California, Oregon, Washington, Northern Nevada, Southern Idaho or Western Utah you should be able to see some part of this man made meteor. The closer you live to the trajectory, which runs from Crescent City, to Mt Shasta, Cal and then through Winnemucca and Elko Nev, and finally to Western Utah, the higher in the sky it will be. With the Stardust mission returning it's comet samples and reentering at the highest speed of any man made object, you'll be able to know exactly when and where to see this amazing man made "meteor". As it stands, the capsule will enter Earth's atmosphere (135 km altitude) at 09:56:39 UT on 2006 January 15 (01:56:39 PDT). Follow the link above to find the tracking charts

Trivia

Answers to the quiz from Show #4
  1. Since meteor showers take the name of the constellation they radiate from why is the meteor shower that radiates from the constellation Bootes called Quadranids? (Answer: Quadrans Muralis''' (Latin for mural quadrant) was a constellation created by J�©r�´me Lalande in 1795. It was located between the constellations of Bo�¶tes and Hercules. It is no longer in use, but the meteor shower Quadrantids is named after it.)
  2. Can you see the International Space Station without a telescope?(Answer: You bet you can! Go to http://www.heavens-above.com/ to find out when you can next see the ISS fly-by)
  3. What is the brightest star in our sky? (Answer: The Sun of course! Trick question so the brightest non-Sun star would be Sirius the Dog Star)
