Many Quasars Are Light Eaters
2012-06-20 04:20:53

Black holes in the early universe needed a few snacks rather than one giant meal to fuel their quasars and help them grow, according to observations from NASA's Spitzer and Hubble space telescopes. Quasars are the brilliant beacons of light that are powered by black holes feasting on captured material, and in the process, heating some of the matter to millions of degrees. The brightest quasars reside in galaxies distorted by collisions with other galaxies. These encounters send lots of gas...

Hidden Patterns Of Light Revealed By Spitzer
2012-06-08 03:30:50

The faint, lumpy glow given off by the very first objects in the universe may have been detected with the best precision yet, using NASA's Spitzer Space Telescope. These faint objects might be wildly massive stars or voracious black holes. They are too far away to be seen individually, but Spitzer has captured new, convincing evidence of what appears to be the collective pattern of their infrared light. The observations help confirm the first objects were numerous in quantity and furiously...

Image 1 - Light Of Alien 'Super-Earth' Detected By Spitzer

Lee Rannals for RedOrbit.com [ Watch the Video ] Light from a "super-Earth" planet that lies beyond our solar system has been detected for the first time by NASA's Spitzer Space Telescope. NASA said that although the planet, 55 Cancri e, is not habitable, meaning it is unable to support life, the detection is a monumental step towards searching for signs of life on other planets. "Spitzer has amazed us yet again," Bill Danchi, Spitzer program scientist at NASA Headquarters in...

WISE Catches Cosmic Dust Bunny
2012-04-27 03:13:54

Images from NASA's Wide-field Infrared Survey Explorer (WISE) reveal an old star in the throes of a fiery outburst, spraying the cosmos with dust. The findings offer a rare, real-time look at the process by which stars like our sun seed the universe with building blocks for other stars, planets and even life. The star, catalogued as WISE J180956.27-330500.2, was discovered in images taken during the WISE survey in 2010, the most detailed infrared survey to date of the entire celestial sky....

Image 1 - Sombrero Galaxy Found To Have A Split Personality
2012-04-25 05:03:49

The Spitzer Space Telescope has helped astronomers reveal that the Sombrero galaxy is both a rotund and a slender disk galaxy. Sombrero is a round elliptical galaxy with a thin disk embedded inside, and is one of the first known to exhibit characteristics of two different types of galaxies. "The Sombrero is more complex than previously thought," Dimitri Gadotti of the European Southern Observatory in Chile, said in a press release. "The only way to understand all we know about this...

A University of Oklahoma assistant professor and colleagues have identified two white dwarf stars considered the oldest and closest known to man.  Astronomers identified these 11- to 12-billion-year-old white dwarf stars only 100 light years away from Earth.  These stars are the closest known examples of the oldest stars in the Universe forming soon after the Big Bang, according to the OU researcher. Mukremin Kilic, assistant professor of physics and astronomy in the OU College...

NASA Extends Kepler, Spitzer, Planck Missions
2012-04-06 04:08:16

NASA is extending three missions affiliated with the Jet Propulsion Laboratory in Pasadena, Calif. -- Kepler, the Spitzer Space Telescope and the U.S. portion of the European Space Agency's Planck mission -- as a result of the 2012 Senior Review of Astrophysics Missions. The 2012 NASA Senior Review report, which includes these three missions and six others also being extended, is available at: http://science.nasa.gov/astrophysics/2012-senior-review/ . "This means scientists can continue...

Public To Get Access To Spectacular Infrared Images Of Galaxies
2012-03-27 08:22:58

For the first time, the general public will be able to browse detailed infrared images of more than 200 galaxies. The pictures, originating from data from the orbiting Spitzer Space Telescope, will be released later this year. Dr George Bendo of the Jodrell Bank center for Astrophysics will highlight the new imagery in a preview at the National Astronomy Meeting in Manchester. The pictures are mid-infrared (24 micron wavelength) reprocessed images of nearby galaxies observed with Spitzer...


Word of the Day
attercop
  • A spider.
  • Figuratively, a peevish, testy, ill-natured person.
'Attercop' comes from the Old English 'atorcoppe,' where 'atter' means 'poison, venom' and‎ 'cop' means 'spider.' 'Coppa' is a derivative of 'cop,' top, summit, round head, or 'copp,' cup, vessel, which refers to 'the supposed venomous properties of spiders,' says the OED. 'Copp' is still found in the word 'cobweb.'
