| NASA's WISE Telescope Detects 4,700 Possibly Hazardous AsteroidsBy Mark Whittington | Yahoo! Contributor Network – 10 hrs ago According to CNN, NASA has announced that there are potentially 4700 asteroids -- give or take 1,500 -- that are large enough and pass close enough to the Earth in their orbits around the sun to constitute a hazard. Hazardous asteroids A hazardous asteroid, as defined by NASA, is a body that is greater than 100 meters or 330 feet in diameter and approaches Earth within 5 million miles, about 20 times the distance from the Earth to the moon.

| The Hubble Space Telescope has found a UFO, but this one is filled with stars instead of little green men. The iconic space telescope snapped an amazing new photo of the "UFO Galaxy" — a galaxy 35 million light-years from Earth that is officially known as NGC 2683. "NGC 2683 is a spiral galaxy seen almost edge-on, giving it the shape of a classic science fiction spaceship," NASA officials wrote in a recent image description. The galaxy was originally discovered on Feb. 5, 1788 by famed astronomer William Herschel. It is located in the Lynx constellation in the northern sky.... |

Astronomy Picture of the Day -- Bright Planets at McMath-Pierce Solar Telescope
Monday 28th of May 2012 05:48:38 PM
Posted by admin / Under Telescope
| Explanation: Bright planets Venus and Jupiter are framed by the National Solar Observatory's McMath-Pierce Solar Telescope in this very astronomical scene. The photo was taken at Kitt Peak National Observatory on March 9. A heliostat sits atop the 100 foot high solar telescope tower to focus the Sun's rays down a long diagonal shaft that reaches underground to the telescope's primary mirror. Of course, after sunset shadows were cast and the structure illuminated by light from the nearly full rising Moon. Opened to begin the night's work, the dome housing Kitt Peak's 2.1 meter reflector is included in the frame,... |
Astronomy Picture of the Day -- Comet Lovejoy over Paranal

| Explanation: Comet Lovejoy (C/2011 W3) survived its close encounter with the Sun earlier this month, taking its place among wonders of the southern skies just in time for Christmas. Seen here before sunrise from Paranal Observatory in Chile, the sungrazing comet's tails stretch far above the eastern horizon. Spanning over 20 degrees they rise alongside the plane of the our Milky Way galaxy. A breathtaking spectacle in itself, Lovejoy performs on this celestial stage with southern stars and nebulae, including the Large and Small Magellanic clouds right of the telescope dome, and the glow of zodiacal light along the left... |

| He was too weak to travel to California last week for the announcement of the mission's first big success -- the discovery of planet Kepler-22b, a rock with similarities to Earth and a sweet-spot distance from its star that creates temperatures and other conditions that could support life. "From what we have measured so far, we say water could exist. We don't say it's there," Koch said, tempering my excitement over when we get to meet our new neighbors...

Spitzer detects comet storm in nearby solar system
Monday 28th of May 2012 05:48:38 PM
Posted by admin / Under Telescope
| NASA's Spitzer Space Telescope has detected signs of icy bodies raining down in an alien solar system. The downpour resembles our own solar system several billion years ago during a period known as the "Late Heavy Bombardment," which may have brought water and other life-forming ingredients to Earth. During this epoch, comets and other frosty objects that were flung from the outer solar system pummeled the inner planets. The barrage scarred our moon and produced large amounts of dust. Now Spitzer has spotted a band of dust around a nearby bright star in the northern sky called Eta Corvi that... |
NASA Photos Bring Millions of Galaxies and Asteroids Down to Earth

| NASA has unveiled a flood of photos showing millions galaxies, stars and asteroids photographed by a prolific sky-mapping telescope that ended its mission earlier this year. For the first time, the space agency publicly released more than half of the 2.7 million images taken by its Wide-field Infrared Survey Explorer (WISE) telescope during its mission to map the entire sky. WISE launched in December 2009 and spent 14 months scanning the heavens in infrared light before shutting down this past February. The $320 million space telescope hunted for asteroids and comets, as well as more distant cosmic objects revealed by... |

The Air Force, which operates the DARPA-developed Space Surveillance Telescope (SST) says the telescope's design, featuring unique image-capturing technology known as a curved charge coupled device (CCD) system, as well as very wide field-of-view, large-aperture... |

| The first spacecraft ever to circle Mercury has beamed home the first-ever photo taken of the small rocky planet from orbit, showing a stark landscape peppered with craters. NASA's Messenger spacecraft snapped the new Mercury photo today (March 29) at 5:20 a.m. EDT (0920 GMT). The photo shows the stark gray landscape of southern Mercury, a view that is dominated by a huge impact crater. "This image is the first ever obtained from a spacecraft in orbit about the solar system's innermost planet," Messenger mission scientists explained in a statement. The new Mercury photo shows a region around the south... |

Small Snack for Milky Way: Astrophysicists Find New Remnants of Neighboring Galaxy in Our Own

Posted by admin / Under Telescope
| An international team of astronomers led by Mary Williams from the Astrophysical Institute Potsdam (AIP) has discovered a new stream of stars in our Milky Way: the "Aquarius Stream," named after the constellation of Aquarius. The stream of stars is a remnant of a smaller galaxy in our cosmic neighbourhood, which has been pulled apart by the gravitational pull of the Milky Way about 700 million years ago. The discovery is a result of the measurement of the velocities of 250,000 stars with the RAVE Survey based at the Australian Astronomical Observatory's UK Schmidt Telescope at Siding Spring Observatory, NSW,... |

| A FOCAL Mission into the Oort Cloud by Paul Gilster on November 15, 2010 After all this time, IÂ’m still trying to wrap my head around the idea of massive objects in space as lenses, their distortion of spacetime offering the ability to see distant objects at huge magnification. On Friday we saw how the lensing effect caused by galactic clusters can be used to study dark energy. And consider the early results from the Herschel-ATLAS project, conducted by ESAÂ’s Herschel Space Observatory. Herschel is scanning large areas of the sky in far-infrared and sub-millimeter light.

New X-ray Image Shows Jupiter's Powerful Sky Lights (auroras bigger than our entire planet)

Posted by admin / Under Telescope
| NASA's Chandra X-ray Observatory has captured the largest data set yet of Jupiter's colorful lights called aurora, yielding a pretty picture that could help solve some mysteries about the phenomenon. The phenomenon is similar to the Northern Lights seen on Earth, thought on a much larger scale. "Jupiter has auroras bigger than our entire planet," said Randy Gladstone of the Southwest Research Institute in San Antonio, Texas. In a NASA statement today, Gladstone called the purple rings in a new colorized image "Northern Lights on steroids. They're hundreds of times more energetic than auroras on Earth." Unlike Earth's auroras, Jupiter's... |
Black Holes Devour Matter Like Piranhas

| Like gluttonous piranhas, supermassive black holes in young galaxy clusters gorge on bountiful gas until little fuel is left, and then they fade away, a new study suggests.Using NASA's Chandra X-ray Observatory, astronomers tallied the number of rapidly growing supermassive black holes, called active galactic nuclei, or AGN, in two populations of galaxy clusters. One group consisted of young-looking clusters located very far from Earth, and the other consisted of an older group located closer to us. The results of the survey, detailed in the July 20 issue of The Astrophysical Journal Letters, showed that the more distant, younger clusters... |

| Displayed in all their exquisite detail, six spectacular galaxies are pictured more clearly that they ever have before. All of them are beautiful examples of spiral galaxies and were captured in images from ESO’s Very Large Telescope (VLT) at the Paranal Observatory in Chile. The pictures were taken in infrared light, using the impressive power of the HAWK-I camera, and will help astronomers understand how the remarkable spiral patterns in galaxies form and evolve.-incredible-new-detail.html#ixzz13uAfNijg |
