Astronomy Picture Of the Day (APOD)
M39: Open Cluster in Cygnus
12.04.2009
Lying just at the limit of human perception is a picturesque starfield containing one of the larger open clusters on the northern sky. Spanning an angle larger than the Moon, M39's relatively few stars lie only about 800 light years distant toward the constellation of Cygnus.
The Big Picture
11.04.2009
Intricate, glowing nebulae that shine in planet Earth's night sky are beautiful to look at in deep images made with telescopes and sensitive cameras. But they are faint and otherwise invisible to the naked-eye. That makes their relative location and extent on the sky difficult to appreciate.
ISS and Astronaut
10.04.2009
These two frames, taken with a video camera and a telescope, reveal remarkable details of the International Space Station (ISS) orbiting some 350 kilometers above planet Earth. Recorded during last month's visit...
Venus Near Inferior Conjunction
9.04.2009
This remarkable picture of a slender crescent Venus was made during daylight hours on March 26. Venus was then very near inferior conjunction, its closest approach to a point on a line directly between Earth and the Sun.
Unusual Dusty Galaxy NGC 7049
8.04.2009
How was this unusual looking galaxy created? No one is sure, especially since spiral galaxy NGC 7049 looks so strange. NGC 7049's strikingly appearance is primarily due to an unusually prominent dust ring seen mostly in silhouette. The opaque ring is much darker than the din of millions of bright stars glowing behind it.
APOD: 2009 April 7 The Colliding Spiral Galaxies of Arp 274
7.04.2009
Two galaxies are squaring off in Virgo and here are the latest pictures. When two galaxies collide, the stars that compose them usually do not. This is because galaxies are mostly empty space and, however bright, stars only take up only a small fraction of that space.
APOD: 2009 April 6 The International Space Station Expands Again
6.04.2009
The developing International Space Station (ISS) has changed its appearance again. In a recently completed mission, the Space Shuttle orbiter Discovery visited the ISS and added components that included a new truss and new solar panels.
Star Party on Planet Earth
4.04.2009
As twilight sweeps around planet Earth tonight (April 4), many amateur astronomers will set up their telescopes for a 24-hour global star party. The planetwide star party is part of 100 Hours of Astronomy (100HA), a project of the International Year of Astronomy 2009.
Around the World in 80 Telescopes
3.04.2009
Want to go on an extraordinary voyage? Today you can, by watching Around the World in 80 Telescopes. The 24-hour long webcast is organized by the European Southern Observatory for the International Year of Astronomy cornerstone project 100 Hours of Astronomy.
100 Hours of Astronomy Begins
2.04.2009
Today, 100 Hours of Astronomy begins, a cornerstone project of the International Year of Astronomy 2009 celebrating the 400th anniversary of Gallileo's original telescopic exploration of the sky. Running from April 2 through...
