Deepest View of Space Yields Young Stars in Andromeda Halo

Title	Deepest View of Space Yields Young Stars in Andromeda Halo

Title	Island Universe, Cosmic Sand
Explanation	On August 13, 2002, while counting Perseid meteors [ http://science.nasa.gov/headlines/y2003/ 17jul_perseids2003.htm ] under dark [ http://www.darksky.org/ida/darksky/ index.html ], early morning Arizona skies, Rick Scott set out to photograph [ http://members.cox.net/rmscott/ gallery_space_sky02.html ] their fleeting but fiery trails. The equipment he used included a telephoto lens and fast color film. After 21 pictures he'd caught only two meteors, but luckily this was one of them. Tracking the sky, his ten minute long exposure shows a field of many stars in our own Milky Way galaxy [ http://www.seds.org/messier/ more/mw.html ], most too faint to be seen by the unaided eye. Flashing [ http://antwrp.gsfc.nasa.gov/apod/ap990219.html ] from lower left to upper right, the bright meteor would have been an easy eyeful though, as friction with Earth's atmosphere vaporized [ http://antwrp.gsfc.nasa.gov/apod/ap020816.html ] the hurtling grain of cosmic sand [ http://antwrp.gsfc.nasa.gov/apod/ap001117.html ], a piece of dust from Comet Swift-Tuttle [ http://comets.amsmeteors.org/comets/pcomets/ 109p.html ]. Just above and left of center, well beyond the stars of the Milky Way, lies the island universe [ http://antwrp.gsfc.nasa.gov/apod/ap020518.html ] known as M31 or the Andromeda galaxy. The visible meteor trail begins about 100 kilometers above Earth's surface, one of the closest celestial objects seen in the sky. In contrast, Andromeda [ http://www.seds.org/messier/m/ m031.html ], about 2 million light-years away, is the most distant object easily visible to the naked-eye.

Title	A Galaxy is not a Comet
Explanation	This gorgeous galaxy and comet portrait [ http://science.nasa.gov/spaceweather/comets/ gallery_iz.html ] was recorded on April 5th, 2002, in the skies over the Oriental Pyrenees near Figueres, Spain [ http://www.odci.gov/cia/publications/factbook/geos/ sp.html ]. From a site above 1,100 meters, astrophotographer [ http://www.skylook.net/nav/indexe.htm ] Juan Carlos Casado used a guided time exposure, fast film, and a telephoto lens to capture the predicted conjunction of the bright Comet Ikeya-Zhang [ http://antwrp.gsfc.nasa.gov/apod/ap020404.html ] (right) and the Andromeda Galaxy [ http://antwrp.gsfc.nasa.gov/apod/ap021021.html ] (left). This stunning celestial scene would also have been a rewarding one for the influential 18th century comet hunter Charles Messier [ http://www.seds.org/messier/xtra/history/ biograph.html ]. While Messier scanned French skies for comets, he carefully cataloged positions of things which were fuzzy and comet-like in appearance but did not move against the background stars and so were definitely not comets. The Andromeda Galaxy [ http://nedwww.ipac.caltech.edu/level5/ANDROMEDA_Atlas/ frames.html ], also known as M31, is the 31st object in his famous not-a-comet catalog [ http://seds.lpl.arizona.edu/messier/xtra/history/ m-cat.html ]. Not-a-comet object number 110 [ http://www.seds.org/messier/m/ m110.html ], a late addition to Messier's catalog, is one of Andromeda's small satellite galaxies, and can be seen here just below M31. Our modern [ http://antwrp.gsfc.nasa.gov/diamond_jubilee/ debate20.html ] understanding [ http://www.astr.ua.edu/goodies/data_resources/ galaxies.text ] holds that the Andromeda galaxy is a large spiral galaxy some 2 million light-years distant [ http://www.anzwers.org/free/universe/localgr.html ]. The photogenic Comet Ikeya-Zhang [ http://www.stardate.org/nightsky/comet_IZ.html ], then a lovely sight in early morning skies was about 80 million kilometers (4 light-minutes) from planet Earth.
