Astronomy Picture Of the Day (APOD)As Above, So Below
A single, long exposure captured these star trails above a remarkably colorful sea of clouds. As seen from Medvednica mountain, the surrounding peaks and lights illuminating the clouds from below are north of Zagreb, Croatia.
Solar Eclipse over Antarctica
Last Friday, the fourth and final partial solar eclipse of 2011 was only visible from high latitudes in the southern hemisphere. If you missed it, check out this dramatic picture of the geocentric celestial event from a very high southern latitude on the continent of Antarctica.
Young Moon Meets Evening Star
Now appearing as planet Earth's evening star, brilliant Venus shines in western skies at twilight. Standing above a rugged horizon and warm sunset colors, the twilight's celestial beacon was joined last Saturday by a Moon 35 hours young in this gorgeous skyscape.
Curiosity Rover Lifts Off for Mars
Next stop: Mars. This past weekend the Mars Science Laboratory carrying the Curiosity Rover blasted off for the red planet atop an Atlas V rocket from Cape Canaveral, Florida, USA, as pictured above.
Across the Center of Centaurus A
A fantastic jumble of young blue star clusters, gigantic glowing gas clouds, and imposing dark dust lanes surrounds the central region of the active galaxy Centaurus A. This image from the Hubble Space Telescope has been processed to present a natural color picture of this cosmic maelstrom.
A Landslide on Asteroid Vesta
Asteroid Vesta is home to some of the most impressive cliffs in the Solar System. Pictured above near the image center is a very deep cliff running about 20 kilometers from top to bottom. The image was taken by the robotic Dawn spacecraft that began orbiting the 500-kilometer space rock earlier this year.
Shuttle Plume Shadow Points to the Moon
Why would the shadow of a space shuttle launch plume point toward the Moon? In early 2001 during a launch of Atlantis, the Sun, Earth, Moon, and rocket were all properly aligned for this photogenic coincidence.
Pelican Nebula Close Up
The prominent ridge of emission featured in this vivid skyscape is designated IC 5067. Part of a larger emission nebula with a distinctive shape, popularly called The Pelican Nebula, the ridge spans about 10 light-years and follows the curve of the cosmic pelican's head and neck.
A Glimpse of CLIMSO
A tantalizing glimpse inside this dome was captured after sunset at the mountain top Pic Du Midi Observatory in the French Pyrenees. But while most are just beginning their work at sunset, this observatory's day was done.
Caught in the Afterglow
In this artist's illustration, two distant galaxies formed about 2 billion years after the big bang are caught in the afterglow of GRB090323, a gamma-ray burst seen across the Universe. Shining through...
