Astronomy Picture Of the Day (APOD)
Barnards Loop around the Horsehead Nebula
24.02.2009
Why is the Horsehead Nebula surrounded by a bubble? Although hard to make out above, the famous Horsehead Nebula is the slight dark indentation in the bright streak just to the left of the image center. Glowing like an emission nebula, the origin of the bubble, known as Barnard's Loop, is currently unknown.
An Etruscan Vase Moon Rising
23.02.2009
What's happened to the Moon? Nothing, although from some locations, February's full moon, which occurred about two weeks ago, appeared strangely distorted as it rose. Visible in particular was a curiously inverted...
Orion Nebula: The Hubble View
22.02.2009
Few cosmic vistas excite the imagination like the Orion Nebula. Also known as M42, the nebula's glowing gas surrounds hot young stars at the edge of an immense interstellar molecular cloud only 1,500 light-years away.
The Swift View of Comet Lulin
21.02.2009
Now growing brighter, Comet Lulin is headed for its closest approach to planet Earth early next week. But the comet's greenish glow, familiar to earthbound skygazers, is replaced by false colors in this premier view from the orbiting Swift satellite.
Snake in the Dark
20.02.2009
Dark nebulae snake across a gorgeous expanse of stars in this telescopic view toward the pronounceable constellation Ophiuchus and the center of our Milky Way Galaxy. In fact, the twisting central shape seen here is well known as the Snake Nebula.
Mauna Kea Milky Way Panorama
19.02.2009
Aloha and welcome to a breathtaking skyscape. The dreamlike panoramic view looks out from the 4,200 meter volcanic summit of Mauna Kea, Hawai'i, across a layer of clouds toward a starry night sky and the rising Milky Way.
Satellites Collide in Low Earth Orbit
18.02.2009
How often do satellites collide? Although minuscule space debris may strike any satellite on occasion, the first known collision between time two full satellites occurred only last week. Even though thousands of satellites have been launched, the low collision rate is caused by the great vastness of space.
Unusual Red Glow Over Minnesota
17.02.2009
What in heaven's blazes is that? When landing in Minneapolis, Minnesota, USA in 2002, just after his flight descended below cloud level in the early evening, passenger Tyler Blessing saw and photographed "huge...
The Great Carina Nebula
16.02.2009
A jewel of the southern sky, the Great Carina Nebula, aka NGC 3372, spans over 300 light-years, one of our Galaxy's largest star forming regions. Like the smaller, more northerly Great Orion Nebula...
Antarctic Ice Shelf Vista
15.02.2009
It's all gone but the mountains. Most of the sprawling landscape of ice that lies between the mountains visible above has now disintegrated. The above picture was taken in Antarctica from the top of Grey Nunatak, one of three Seal Nunatak mountains that border the Larsen B Ice-Shelf.
