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.

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.



Taki's Star Atlas chart #104

Puppis - the Poop or Stern - Puppis, the 'Poop' Deck or Stern of the Argos Puppis is actually part of Argo Navis, the ship of Jason and the Argonauts
Invented/listed by: changed by Lacaille in 1763
Deep Sky objects: M 46 bright open cluster containing about 100 moderately concentrated stars. The planetary nebula NGC 2438 lies seemingly embedded in its northeastern edge,
M 47 open cluster contains about 50 relatively bright stars moderately concentrated to the center.
M 93, Another fine open cluster with a distinct triangular or wedge shape.
NGC 2440 planetary nebula very fuzzy with no apparent central star greenish hue.
Double stars: Yellow supergiant xi Pup of 3.34 mag shows an orange companion when viewed through binoculars
Variable stars: L2 Pup is a red giant which brightness varies from 3rd to 6th magnitude roughly every 140 days
V Pup is an eclipsing binary every 35 hours the brightness goes down from 4.5 mag to 5.1 mag when the fainter star crosses the brighter one in the line of sight.

Timon: Yeah?
Pumbaa: Ever wonder what those sparkly dots are up there?
Timon: Pumbaa. I don't wonder; I know.
Pumbaa: Oh. What are they?
Timon: They're fireflies. Fireflies that uh... got stuck up on that big... bluish-black... thing.
Pumbaa: Oh. Gee. I always thought that they were balls of gas burning billions of miles away.
Timon: Pumbaa, wit' you, everything's gas.
