Whitney Clavin, Jet Propulsion Laboratory Astronomers using NASA's Spitzer Space Telescope have measured the size of an asteroid candidate for NASA's Asteroid Redirect Mission (ARM), a proposed spacecraft concept to capture either a small asteroid, or a boulder from an asteroid. The near-Earth asteroid, called 2011 MD, was found to be roughly 20 feet (6 meters) in size, and its structure appears to contain a lot of empty space, perhaps resembling a pile of rubble. Spitzer's infrared vision...

NASA NASA's Wide-field Infrared Survey Explorer (WISE) and Spitzer Space Telescope have discovered what appears to be the coldest "brown dwarf" known -- a dim, star-like body that, surprisingly, is as frosty as Earth's North Pole. Images from the space telescopes also pinpointed the object's distance to 7.2 light-years away, earning it the title for fourth closest system to our sun. The closest system, a trio of stars, is Alpha Centauri, at about 4 light-years away. "It's very...

Loops of Gas and Dust Rise from Planetary Disks

Brett Smith for redOrbit.com - Your Universe Online Almost a decade ago, scientists using NASA's Spitzer Space Telescope found that planet-forming disks around young stars are heated by starlight and glow with infrared light. However, these scientists found that additional infrared light was originating from an unknown source. Now, new models developed by NASA have revealed why these stars emit more infrared light than expected – gas and dust magnetically suspended above the disks...

WISE Birthday Image
2013-12-13 15:43:15

Brett Smith for redOrbit.com - Your Universe Online To coincide with the fourth anniversary of NASA’s Wide-Field Infrared Survey Explorer (WISE) mission, the space agency has released an image showing a unique juxtaposition – a distant, dying star called the Helix nebula, surrounded by a halo of relatively close asteroids tracks. The release of the image and the mission’s fourth anniversary comes after NASA brought WISE out of hibernation back in August to search for more...

NASA Scientists Discover Cool Brown Dwarfs That Are Still Pretty Warm
2013-09-06 11:02:56

Brett Smith for redOrbit.com - Your Universe Online Two years ago NASA scientists revealed a new class of stars, dubbed ‘Y dwarfs,' thought to be about as warm as the human body. However, newly published research indicates that these cold stars are probably a bit warmer than the boiling point of water. These stars are believed to have a mass about 5 to 20 times that of Jupiter. Unlike our sun, these types of brown dwarf stars derive their energy via gravitational contraction, a...

Space Observatory's Mission Ends
2013-04-29 15:06:58

Lee Rannals for redOrbit.com - Your Universe Online The European Space Agency's (ESA) Herschel observatory has officially run out of liquid coolant, ending its mission. The space observatory launched nearly four years ago with a goal to help reveal some of the cooler sides of the universe, including planet, star and galaxy formation. "Herschel gave us the opportunity to peer into the dark and cold regions of the universe that are invisible to other telescopes," said John Grunsfel,...
