The Jets of NGC 1097
27.11.2009
Enigmatic spiral galaxy NGC 1097 lies about 45 million light-years away in the southern constellation Fornax. The small companion galaxy, just below and left of center, that seems to be wrapped in its spiral arms, is not NGC 1097's most peculiar feature though.
M78 Wide Field
26.11.2009
Interstellar dust clouds and glowing nebulae abound in the fertile constellation of Orion. One of the brightest, M78, is centered in this colorful, wide field view, covering an area north of Orion's belt. At a distance of about 1,500 light-years, the bluish reflection nebula is around 5 light-years across.
All Sky Milky Way Panorama
25.11.2009
If you could go far away from the Earth and look around the entire sky -- what would you see? Such was the goal of the All-Sky Milky Way Panorama 2.0 project of Axel Mellinger.
Cassini Flyby Shows Enceladus Venting
24.11.2009
What's happening on the surface of Saturn's moon Enceladus? Enormous ice jets are erupting. Giant plumes of ice have been photographed in dramatic fashion by the robotic Cassini spacecraft during this past weekend's flyby of Saturn's moon Enceladus.
Crescent Earth from the Departing Rosetta Spacecraft
23.11.2009
Goodbye Earth. Earlier this month, ESA's interplanetary Rosetta spacecraft zoomed past the Earth on its way back across the Solar System. Pictured above, Earth showed a bright crescent phase featuring the South Pole to the passing rocket ship.
Light Echoes from V838 Mon
22.11.2009
What caused this outburst of V838 Mon? For reasons unknown, star V838 Mon's outer surface suddenly greatly expanded with the result that it became the brightest star in the entire Milky Way Galaxy in January 2002. Then, just as suddenly, it faded.
NGC 253: Dusty Island Universe
21.11.2009
Shiny NGC 253 Galaxy, is one of the brightest spiral galaxies visible, and also one of the dustiest. Some call it the Silver Dollar Galaxy for its appearance in small telescopes, or just the Sculptor Galaxy for its location within the boundaries of the southern constellation Sculptor.
Meteor between the Clouds
20.11.2009
This bright meteor streaked through dark night skies over Sutherland, South Africa on November 15. Potentially part of the annual Leonid meteor shower, its sudden, brilliant appearance, likened to a camera's flash, was captured by chance as it passed between two clouds.
Leonid over Mono Lake
19.11.2009
Eerie spires of rock rise from shore of Mono Lake in the foreground of this early morning skyscape. The salty, mineral-laden lake is located in California's eastern Sierra Nevada mountain range and the spindly rock formations are naturally formed limestone towers called tufa.
Water Discovered in Moon Shadow
18.11.2009
Why is there water on the Moon? Last month, the LCROSS mission crashed a large impactor into a permanently shadowed crater near the Moon's South Pole. A plume of dust rose that was visible to the satellite, although hard to discern from Earth. The plume is shown above in visible light.
