Astronomy Picture Of the Day (APOD)
Star Formation in the Tarantula Nebula
16.05.2012
The largest, most violent star forming region known in the whole Local Group of galaxies lies in our neighboring galaxy the Large Magellanic Cloud (LMC). Were the Tarantula Nebula at the distance of the Orion Nebula -- a local star forming region -- it would take up fully half the sky.
All the Water on Planet Earth
15.05.2012
How much of planet Earth is made of water? Very little, actually. Although oceans of water cover about 70 percent of Earth's surface, these oceans are shallow compared to the Earth's radius.
Virtual Flight Over Asteroid Vesta
14.05.2012
What would it be like to fly over the asteroid Vesta? Animators from the German Aerospace Center recently took actual images and height data from NASA's Dawn mission currently visiting Vesta to generate such a virtual movie.
Spiral Galaxy NGC 1672 from Hubble
13.05.2012
Many spiral galaxies have bars across their centers. Even our own Milky Way Galaxy is thought to have a modest central bar. Prominently barred spiral galaxy NGC 1672, pictured above, was captured in spectacular detail in image taken by the orbiting Hubble Space Telescope.
The Hydra Cluster of Galaxies
12.05.2012
Two stars within our own Milky Way galaxy anchor the foreground of this cosmic snapshot. Beyond them lie the galaxies of the Hydra Cluster. In fact, while the spiky foreground stars are hundreds of light-years distant, the Hydra Cluster galaxies are over 100 million light-years away.
Sun vs Super Moon
11.05.2012
The Super Moon wins, by just a little, when its apparent size is compared to the Sun in this ingenious composite picture. To make it, the Full Moon on May 6 was photographed with the same camera and telescope used to image the Sun (with a dense solar filter!) on the following day.
Green Flash and Super Moon
10.05.2012
It was really not about superheroes as on May 6 the much touted Super Moon, the largest Full Moon of 2012, rose over this otherwise peaceful harbor. And no supervillains were present either as boats gently rocked at their moorings near the checkerboard La Perdrix lighthouse on the coast of Brittany, France.
Shuttle Enterprise Over New York
9.05.2012
What's that in the background? Two famous New York City icons stand tall in the above photo taken last week. On the left looms the Statue of Liberty, a universal symbol of freedom, while on the right rises the Empire State Building, now the second largest building in the city.
The Light of Stars
8.05.2012
What's moving? Time lapse videos of the sky can be quite spectacular when they last long enough for stars, planets, aurora, and clouds to appear to move in just a few seconds. Pictured...
Supermoon Over Paris
7.05.2012
Did you see that full Moon Saturday night? Dubbed a supermoon, the latest fully illuminated moon appeared slightly larger than usual because it occurred unusually near the closest point in its orbit to Earth. Pictured above, the supermoon was captured Saturday night rising behind the top of the Eiffel Tower in Paris, France.
