Astronomy Picture Of the Day (APOD)
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.
Carina Pillar and Jets
1.10.2009
This cosmic pillar of gas and dust is nearly 2 light-years wide. The structure lies within one of our galaxy's largest star forming regions, the Carina Nebula, shining in southern skies at a distance of about 7,500 light-years.
Saturn at Equinox
30.09.2009
How would Saturn look if its ring plane pointed right at the Sun? Before last month, nobody knew. Every 15 years, as seen from Earth, Saturn's rings point toward the Earth and appear to disappear.
Orion in Gas, Dust, and Stars
29.09.2009
The constellation of Orion holds much more than three stars in a row. A deep exposure shows everything from dark nebula to star clusters, all imbedded in an extended patch of gaseous wisps in the greater Orion Molecular Cloud Complex.
Water Discovered on the Moon
28.09.2009
Water has been discovered on the surface of the Moon. No lakes have been found, but rather NASA's Moon Mineralogy Mapper aboard India's new Chandrayaan-1 lunar orbiter radios back that parts of the Moon's surface absorb a very specific color of light identified previously only with water.
To Fly Free in Space
27.09.2009
At about 100 meters from the cargo bay of the space shuttle Challenger, Bruce McCandless II was further out than anyone had ever been before. Guided by a Manned Maneuvering Unit (MMU), astronaut McCandless, pictured above, was floating free in space.
