Astronomy Picture Of the Day (APOD)
Trees, Sky, Galactic Eye
29.06.2010
Is beauty in the eye of this beholder? Earlier this month, over RIunion Island in the Indian Ocean, a playful photographer with an eye for the sky took eight images and composed the above intriguing picture.
A Partial Lunar Eclipse
28.06.2010
What's happened to the Moon? This past weekend, once again, part of the Moon moved through the Earth's shadow. This happens about once or twice a year, on the average, but not each month since the Moon's orbit around the Earth is slightly tilted.
All the Colors of the Sun
27.06.2010
It is still not known why the Sun's light is missing some colors. Shown above are all the visible colors of the Sun, produced by passing the Sun's light through a prism-like device.
Young Star Cluster Westerlund 2
26.06.2010
Dusty stellar nursery RCW 49 surrounds young star cluster Westerlund 2 in this remarkable composite skyscape from beyond the visible spectrum of light. Infrared data from the Spitzer Space Telescope is shown in black...
The Starry Night of Alamut
25.06.2010
A meteor's streak and the arc of the Milky Way hang over the imposing mountain fortress of Alamut in this starry scene. Found in the central Alborz Mountains of Iran, Alamut Castle was built into the rock in the 9th century. The name means Eagle's Nest.
The Dark Tower in Scorpius
24.06.2010
In silhouette against a crowded star field toward the constellation Scorpius, this dusty cosmic cloud evokes for some the image of an ominous dark tower. In fact, clumps of dust and molecular gas collapsing...
Sunset from the International Space Station
23.06.2010
What are these strange color bands being seen from the International Space Station? The Sun setting through Earth's atmosphere. Pictured above, a sunset captured last month by the ISS's Expedition 23 crew shows in vivid detail many layers of the Earth's thin atmosphere.
Islands of Four Mountains from Above
22.06.2010
Our Earth is covered by volcanoes. Volcanoes are breaks in the Earth's cool surface where hot liquid rock from the interior comes out -- sometimes suddenly. In the above image from the ASTER camera...
Sunrise Solstice at Stonehenge
21.06.2010
Today the Sun reaches its northernmost point in planet Earth's sky. Called a solstice, the date traditionally marks a change of seasons -- from spring to summer in Earth's Northern Hemisphere and from fall to winter in Earth's Southern Hemisphere.
Abell 2218: A Galaxy Cluster Lens
20.06.2010
What are those strange filaments? Background galaxies. Gravity can bend light, allowing huge clusters of galaxies to act as telescopes, and distorting images of background galaxies into elongated strands. Almost all of the bright objects in this Hubble Space Telescope image are galaxies in the cluster known as Abell 2218.
