Astronomy Picture Of the Day (APOD)
Comet Lulin Approaches
2.02.2009
How bright will Comet Lulin become? No one knows for sure. Although it is notoriously difficult to accurately predict the brightness of newly discovered comets, Comet Lulin could well become visible to the unaided eye later this month.
Auroral Corona Over Norway
1.02.2009
Higher than highest communications tower, higher than highest mountain, higher than highest airplane, lies the realm of the aurora. Auroras rarely reach below 60 kilometers, and can range up to 1000 kilometers. Aurora light results from energetic electrons and protons striking molecules in the Earth's atmosphere.
Simeis 147: Supernova Remnant
31.01.2009
It's easy to get lost following the intricate filaments in this detailed image of faint supernova remnant Simeis 147. Also cataloged as Sh2-240 and seen towards the constellation Taurus, it covers nearly 3 degrees (6 full moons) on the sky.
NGC 1579: Trifid of the North
30.01.2009
Colorful NGC 1579 resembles the better known Trifid Nebula, but lies much farther north in planet Earth's sky, in the heroic constellation Perseus. About 2,100 light-years away and 3 light-years across...

Of course, everyone is concerned about what to wear to a solar eclipse. This is a great example though, especially for the first eclipse of the International Year of Astronomy 2009. In the picture...
A Partial Eclipse Over Manila Bay
28.01.2009
What's happened to the setting Sun? An eclipse! Two days ago, the Moon eclipsed part of the Sun as visible from parts of Africa, Australia, and Asia. In particular the above image, taken from the Mall of Asia seawall, caught a partially eclipsed Sun setting over Manila Bay in the Philippines.
The Milky Way Over Mauna Kea
27.01.2009
Have you ever seen the band of our Milky Way Galaxy? In a clear sky from a dark location at the right time, a faint band of light becomes visible across the sky. Soon after your eyes become dark adapted, you might spot the band for the first time. It may then become obvious.
AE Aurigae and the Flaming Star Nebula
26.01.2009
Is star AE Aurigae on fire? No. Even though AE Aurigae is named the flaming star, the surrounding nebula IC 405 is named the Flaming Star Nebula, and the region appears to harbor red smoke, there is no fire.
Annular Eclipse: The Ring of Fire
25.01.2009
Tomorrow, a few lucky people may see a "ring of fire." That's a name for the central view of an annular eclipse of the Sun by the Moon. At the peak of this...
The Bubble Nebula
24.01.2009
Blown by the wind from a massive star, this interstellar apparition has a surprisingly familiar shape. Cataloged as NGC 7635, it is also known simply as The Bubble Nebula. This colorful telescopic image includes a long exposure through a hydrogen alpha filter to reveal details of the cosmic bubble and its environment.
