Astronomy Picture Of the Day (APOD)
Planetary Nebula Abell 7
5.12.2013
Very faint planetary nebula Abell 7 is some 1,800 light-years distant, just south of Orion in planet Earth's skies in the constellation Lepus, The Hare. Surrounded by Milky Way stars and near...
Comet Lovejoy through Morby Castle Ruins
4.12.2013
This new comet is quite photogenic. Comet Lovejoy, discovered only three months ago, was imaged through ruins of ancient MZhrby Castle in Sweden last week sporting a green-glowing coma and tails trailing several degrees.
The Colorful Clouds of Rho Ophiuchi
3.12.2013
The many spectacular colors of the Rho Ophiuchi (oh'-fee-yu-kee) clouds highlight the many processes that occur there. The blue regions shine primarily by reflected light. Blue light from the star Rho Ophiuchi and nearby stars reflects more efficiently off this portion of the nebula than red light.
Comet Lovejoy Before Galaxy M63
2.12.2013
Comet Lovejoy was captured last week passing well in front of spiral galaxy M63. Discovered only three months ago and currently near its maximum brightness, Comet Lovejoy can be seen near the Big Dipper from dark northerly locations before dawn with the unaided eye.
A Laser Strike at the Galactic Center
1.12.2013
Why are these people shooting a powerful laser into the center of our Galaxy? Fortunately, this is not meant to be the first step in a Galactic war. Rather, astronomers at the Very Large Telescope (VLT) site in Chile are trying to measure the distortions of Earth's ever changing atmosphere.
Surprising Comet ISON
30.11.2013
After failing to appear for Sun staring spacecraft at perihelion, its harrowing closest approach to the Sun, sungrazing Comet ISON was presumed lost. But ISON surprised observers yesterday as material still traveling along the comet's trajectory became visible and even developed an extensive fan-shaped dust tail.
Comet ISON Before and After
29.11.2013
Sungrazing Comet ISON reached perihelion, its closest approach to the Sun, yesterday, November 28, at 18:45 UT. The comet passed just over 1 million kilometers above the solar surface, a distance less than the diameter of the Sun.
NGC 1999: South of Orion
28.11.2013
South of the large star-forming region known as the Orion Nebula, lies bright blue reflection nebula NGC 1999. At the edge of the Orion molecular cloud complex some 1,500 light-years distant, NGC 1999's illumination is provided by the embedded variable star V380 Orionis.
Comet ISON Rising
27.11.2013
Will Comet ISON survive tomorrow's close encounter with the Sun? Approaching to within a solar diameter of the Sun's surface, the fate of one of the most unusual comets of modern times will finally be determined.
Cap Cloud over the Sierra Nevadas
26.11.2013
One might say this was a bell weather day for the Sierra Nevada mountains. In January, just as the Sun was setting above the district of AlbayzMn in Grenada, Spain, a huge cloud appeared as a bell capping the Veleta peak.
