Astronomy Picture Of the Day (APOD)
Starry Night by Vincent van Gogh
11.10.2009
The painting Starry Night is one of the most famous icons of the night sky ever created. The scene was painted by Vincent van Gogh in southern France in 1889. The swirling style of Starry Night appears, to many, to make the night sky come alive.
LCROSS Centaur Impact Flash
10.10.2009
This mid-infrared image was taken in the last minutes of the LCROSS flight mission to the Moon. The small white spot (enlarged in the insets) seen within the dark shadow of lunar crater walls is the initial flash created by the impact of a spent Centaur upper stage rocket.
Starburst Galaxy IC 10
9.10.2009
Lurking behind dust and stars near the plane of our Milky Way Galaxy, IC 10 is a mere 2.3 million light-years distant. Its light dimmed by the intervening dust, the irregular dwarf galaxy still shows off vigorous star-forming regions that shine with a telltale reddish glow in this colorful skyscape.
Target Crater Cabeus
8.10.2009
About 100 kilometers from the Moon's South Pole, 100 kilometer wide crater Cabeus is the target for two LCROSS mission spacecraft on course to impact the Moon tomorrow. The shadowed crater is strongly foreshortened in this mosaic, a representative view of the region for earthbound telescopes.
A Double Ringed Basin on Mercury
7.10.2009
What created the internal second ring of this double ringed basin on Mercury? No one is sure. The unusual feature spans 160 kilometers and was imaged during the robotic MESSENGER spacecraft's swing past our Solar System's innermost planet last week.
The Lagoon Nebula from GigaGalaxy Zoom
6.10.2009
The large majestic Lagoon Nebula is home for many young stars and hot gas. Spanning 100 light years across while lying only about 5000 light years distant, the Lagoon Nebulae is so big and bright that it can be seen without a telescope toward the constellation of Sagittarius.
The International Space Station Over Earth
5.10.2009
After undocking, the space shuttle Discovery crew got a memorable view of the developing International Space Station (ISS). Pictured orbiting high above Earth last month, numerous solar panels, trusses, and science modules of the ISS were visible. The Discovery crew brought mission specialist Nicole Stott to the ISS, and returned astronaut Timothy Kopra to Earth.
The Same Color Illusion
4.10.2009
Are square A and B the same color? They are. Are too. To verify this, click here to see them connected. The above illusion, called the same color illusion, illustrates that purely human observations in science may be ambiguous or inaccurate. Even such a seemingly direct perception as relative color.
Old Faithful Moon
3.10.2009
Scheduled to illuminate the landscape throughout the night tomorrow, October's bright Full Moon will also be called the Harvest Moon. Traditionally, the Harvest Moon is the Full Moon closest to the autumnal equinox. But in this vacation snapshot, the Full Moon could be called the "Old Faith-Full Moon".
Comet and Orion
2.10.2009
These colorful panels both feature a familiar northern hemisphere astronomical sight: the stellar nursery known as the Great Orion Nebula. They also offer an intriguing and unfamiliar detail of the nebula rich skyscape -- a passing comet.
