Astronomy Picture Of the Day (APOD)
Dark River Wide Field
19.07.2010
A Dark River of dust seems to run from our Galactic Center, then pool into a starfield containing photogenic sky wonders. Scrolling right will reveal many of these objects including (can you find?)...
The Antennae Galaxies in Collision
18.07.2010
Two galaxies are squaring off in Corvus and here are the latest pictures. But when two galaxies collide, the stars that compose them usually do not. That's because galaxies are mostly empty space and, however bright, stars only take up only a small amount of that space.
Galaxies in the River
17.07.2010
Large galaxies grow by eating small ones. Even our own galaxy practices galactic cannibalism, absorbing small galaxies that get too close and are captured by the Milky Way's gravity. In fact, the practice...
Shaping NGC 6188
16.07.2010
Dark shapes with bright edges winging their way through dusty NGC 6188 are tens of light-years long. The emission nebula is found near the edge of an otherwise dark large molecular cloud in the southern constellation Ara, about 4,000 light-years away.
Andes Sunset Eclipse
15.07.2010
On July 11, after a long trek eastward across the southern Pacific Ocean, the Moon's shadow reached landfall in South America. In a total solar eclipse close to sunset, silhouetted Moon and Sun hugged the western horizon, seen here above the Andes mountains near the continent's southern tip.
Easter Island Eclipse
14.07.2010
Makemake, a god in Easter Island mythology, may have smiled for a moment as clouds parted long enough to reveal this glimpse of July 11's total solar eclipse to skygazers. In the foreground...
Mosaic: Welcome to Planet Earth
13.07.2010
Welcome to Planet Earth, the third planet from a star named the Sun. The Earth is shaped like a sphere and composed mostly of rock. Over 70 percent of the Earth's surface is water. The planet has a relatively thin atmosphere composed mostly of nitrogen and oxygen.
Moons Beyond the Rings of Saturn
12.07.2010
What's happened to that moon of Saturn? Nothing -- Saturn's moon Rhea is just partly hidden behind Saturn's rings. In April, the robotic Cassini spacecraft now orbiting Saturn took this narrow-angle view looking across the Solar System's most famous rings.
Warped Sky: Star Trails Panorama
11.07.2010
What's happened to the sky? A time warp, of sorts, and a digital space warp too. The time warp occurs because this image captured in a single frame a four hour exposure of the night sky. As a result, prominent star trails are visible.
Ecliptic New Zealand
10.07.2010
Four bright celestial beacons and a faint triangle of light follow the plane of the ecliptic as it arcs high through this southern hemisphere night skyscape. Seen on a July winter night from Lake...
