Astronomy Picture Of the Day (APOD)
Messier 96
15.06.2007
Dust lanes seem to swirl around the core of Messier 96 in this colorful, detailed portrait of the beautiful island universe. Of course M96 is a spiral galaxy, and counting the faint arms extending beyond the brighter central region it spans 100 thousand light-years or so, about the size of our own Milky Way.
vdB 152: Reflection Nebula in Cepheus
14.06.2007
Described as a "dusty curtain" or "ghostly apparition", mysterious reflection nebula vdB 152 really is very faint. It lies about 1400 light-years away, along the northern Milky Way in the royal constellation Cepheus. Near...
Warped Sky: Star Trails Panorama
13.06.2007
What's happened to the sky? A time warp, of sorts, and a digital space warp too. The time warp occurs because the above image captured in a single frame a four hour exposure of the night sky. Prominent and picturesque star trails are visible.
Shuttle Plume
12.06.2007
What kind of cloud is that? Not a naturally occurring one. Pictured above is the drifting smoke plume left over from last Friday's launch of the Space Shuttle Atlantis. The twisted plume was captured shortly after launch high above NASA's massive Vehicle Assembly Building, the largest single story building in the world.
The Merope Reflection Nebula
11.06.2007
Reflection nebulas reflect light from a nearby star. Many small carbon grains in the nebula reflect the light. The blue color typical of reflection nebula is caused by blue light being more efficiently scattered by the carbon dust than red light.
Looking Back at an Eclipsed Earth
10.06.2007
Here is what the Earth looks like during a solar eclipse. The shadow of the Moon can be seen darkening part of Earth. This shadow moved across the Earth at nearly 2000 kilometers per hour.
Globular Star Cluster M3
9.06.2007
This immense ball of half a million stars older than the Sun lies over 30,000 light-years away. Cataloged as M3 (and NGC 5272), it is one of about 150 globular star clusters that roam the halo of our Milky Way Galaxy.
Markarian s Eyes
8.06.2007
Across the heart of the Virgo Galaxy Cluster lies a string of galaxies known as Markarian's Chain. Prominent in Markarian's Chain are these two interacting galaxies, NGC 4438 (left) and NGC 4435 - also known as The Eyes.
Great Mountain Moonrise
7.06.2007
On May 31st, a gorgeous Full Moon rose over Uludag Mountain in Bursa Province, Turkey. This alluring telephoto view of the twilight scene is a composite of images taken roughly every two minutes beginning shortly after Sunset, following the rising Moon as it moves up and to the right.
Dust Sculptures in the Rosette Nebula
6.06.2007
What creates the cosmic dust sculptures in the Rosette Nebula? Noted for the common beauty of its overall shape, parts of the Rosette Nebula, also known as NGC 2244, show beauty even when viewed up close.
