Astronomy Picture Of the Day (APOD)
The Moon Entering Earth s Shadow
9.10.2015
On September 27/28, from all over the planet's nightside moon watchers enjoyed a total lunar eclipse. The dramatic celestial spectacle was widely imaged, but this lunar eclipse picture may look a little strange and unfamiliar, made with a point and shoot camera of a bygone era.
M83: The Thousand Ruby Galaxy
8.10.2015
Big, bright, and beautiful, spiral galaxy M83 lies a mere twelve million light-years away, near the southeastern tip of the very long constellation Hydra. Prominent spiral arms traced by dark dust lanes and blue star clusters lend this galaxy its popular name, The Southern Pinwheel.
La Palma Eclipse Sequence
7.10.2015
At left, a dramatic image sequence follows late September's total lunar eclipse above a rugged landscape and sea of clouds from the Canary island of La Palma. Composited in a circular fisheye projection...
Flying Past Pluto
6.10.2015
What would it look like to fly past Pluto? The robotic New Horizons spacecraft did just this in late July and continues to return stunning pictures of the dwarf planet. Some well-chosen flyby images have now been digitally sequenced to create the featured video.
Orion Over and Under Tibet
5.10.2015
This night was so serene you could see Orion rise downwards. The unusual spectacle was captured in this single-exposure image, featuring a deep sky around the famous constellation of Orion that appeared both above -- and reflected in -- a peaceful lake in the Gyirong Valley of Tibet, China.
The Sombrero Galaxy in Infrared
4.10.2015
This floating ring is the size of a galaxy. In fact, it is a galaxy -- or at least part of one: the photogenic Sombrero Galaxy, one of the largest galaxies in the nearby Virgo Cluster of Galaxies.
A Blue Blood Moon
3.10.2015
This sharp telescopic snapshot caught late September's Harvest Moon completely immersed in Earth's dark umbral shadow, at the beginning of a total lunar eclipse. It was the final eclipse in a tetrad, a string of four consecutive total lunar eclipses.
Charon: Moon of Pluto
2.10.2015
A darkened and mysterious north polar region informally known as Mordor Macula caps this premier high-resolution portrait of Charon, Pluto's largest moon. Captured by New Horizons near its closest approach on July 14, the image data was transmitted to Earth on September 21.
Eclipsed in Southern Skies
1.10.2015
This stunning panorama in southern skies was recorded on the colorful night of September 27/28 from Carngegie Las Campanas Observatory. A diffuse glow and dark rifts of the central Milky Way hang over domes of the twin 6.5 meter Magellan telescopes. But most eye-catching is the deep red glow of the Moon.
Seasonal Streaks Point to Recent Flowing Water on Mars
30.09.2015
What creates these changing streaks on Mars? Called Recurring Slope Linea (RSL), these dark features start on the slopes of hills and craters but don't usually extend to the bottom. What's even...
