Astronomy Picture Of the Day (APOD)
Gemini Observatory North
15.10.2016
It does look like a flying saucer, but this technologically advanced structure is not here to deliver the wise extraterrestrial from the scifi classic movie The Day the Earth Stood Still. It is here to advance our knowledge of the Universe though.
Herschel s Orion
14.10.2016
This dramatic image peers within M42, the Orion Nebula, the closest large star-forming region. Using data at infrared wavelengths from the Herschel Space Observatory, the false-color composite explores the natal cosmic cloud a mere 1,500 light-years distant.
Galaxies from the Altiplano
13.10.2016
The central bulge of our Milky Way Galaxy rises over the northern Chilean Atacama altiplano in this postcard from planet Earth. At an altitude of 4500 meters, the strange beauty of the desolate landscape could almost belong to another world though.
Penumbral Lunar Eclipse
12.10.2016
Does this Moon look a little different to you? Although shown in spectacular detail, the full face of Earth's most familiar satellite appears slightly darker than usual, in particular on the upper left, because it is undergoing a penumbral lunar eclipse.
The Cygnus Wall of Star Formation
11.10.2016
Sometimes, stars form in walls -- bright walls of interstellar gas. In this vivid skyscape, stars are forming in the W-shaped ridge of emission known as the Cygnus Wall. Part of a larger emission nebula with a distinctive outline popularly called The North America Nebula, the cosmic ridge spans about 20 light-years.
The Winds of Earth
10.10.2016
Which way is the wind blowing? The featured map can tell you this and much more, no matter your location on planet Earth. The dynamic map displays supercomputer forecasts drawn from multiple sources of global satellite data updated every three hours.
Hurricane Ivan from the Space Station
9.10.2016
Ninety percent of the houses on Grenada were damaged by the destructive force of Hurricane Ivan. At its peak in 2004, Ivan was a Category 5 hurricane, the highest power category on the Saffir-Simpson Scale, and created sustained winds in excess of 200 kilometers per hour.
Moon, Mercury, and Twilight Radio
8.10.2016
Sharing dawn's twilight with the Moon on September 29, Mercury was about as far from the Sun as it can wander, the innermost planet close to its maximum elongation in planet Earth's skies.
The Hydrogen Clouds of M33
7.10.2016
Gorgeous spiral galaxy M33 seems to have more than its fair share of glowing hydrogen gas. A prominent member of the local group of galaxies, M33 is also known as the Triangulum Galaxy and lies about 3 million light-years distant.
Trifid, Lagoon, and Mars
6.10.2016
Bright nebulae and star clusters along this 5 degree wide field of view are popular stops on telescopic tours of the constellation Sagittarius and the crowded starfields of the central Milky Way. Cataloged...
