Jupiter s Triple Shadow Transit
2.11.2013
This webcam and telescope image of banded gas giant Jupiter shows the transit of three shadows cast by Jupiter's moons in progress, captured in Belgian skies on October 12 at 0528 UT. Such a three shadow transit is a relatively rare event, even for a large planet with many moons.
NGC 7841: The Smoke Nebula in Frustriaus
1.11.2013
NGC 7841 is probably known as the Smoke Nebula, found in the modern constellation of Frustriaus, the frustrated astrophotographer. Only a few light-nanoseconds from planet Earth, The Smoke Nebula is not an expanding supernova remnant along the plane of our Milky Way galaxy, though it does look a lot like one.
Night on a Spooky Planet
31.10.2013
What spooky planet is this? Planet Earth of course, on the dark and stormy night of September 12 at Hverir, a geothermally active area along the volcanic landscape in northeastern Iceland. Geomagnetic storms produced...
A Spectre in the Eastern Veil
30.10.2013
Frightening forms and scary faces are a mark of the Halloween season. They also haunt this cosmic close-up of the eastern Veil Nebula. The Veil Nebula itself is a large supernova remnant, the expanding debris cloud from the death explosion of a massive star.
Horsehead and Orion Nebulas
29.10.2013
The dark Horsehead Nebula and the glowing Orion Nebula are contrasting cosmic vistas. Adrift 1,500 light-years away in one of the night sky's most recognizable constellations, they appear in opposite corners of the above stunning mosaic.
The Great Comet of 1680 Over Rotterdam
28.10.2013
Was there ever another comet like ISON? Although no two comets are exactly alike, one that appears to have had notable similarities was Comet Kirch, the Great Comet of 1680. Like approaching Comet ISON, Comet Kirch was a bright sungrazer, making a very close approach to the surface of the Sun.
Sungrazer
27.10.2013
Arcing toward a fiery fate, this Sungrazer comet was recorded by the SOHO spacecraft's Large Angle Spectrometric COronagraph(LASCO) on December 23, 1996. LASCO uses an occulting disk, partially visible at the lower...
NGC 7789: Caroline s Rose
26.10.2013
Found among the rich starfields of the Milky Way toward the constellation Cassiopeia, star cluster NGC 7789 lies about 8,000 light-years away. A late 18th century deep sky discovery of astronomer Caroline Lucretia Herschel, the cluster is also known as Caroline's Rose.
NGC 7814: The Little Sombrero in Pegasus
25.10.2013
Point your telescope toward the high flying constellation Pegasus and you can find this expanse of Milky Way stars and distant galaxies. Centered on NGC 7814, the pretty field of view would almost be covered by a full moon.
Little Planet Shadowrise
24.10.2013
Warm shades and subtle colors come to the sky in the fading sunlight after shadowrise on this little planet. Of course the little planet is planet Earth, and this nadir-to-zenith, around-the-horizon mosaic maps the view from a small airfield near the town of Intendente Alvear, La Pampa province, Argentina.
