Cometary Origins For Most Centaurs: WISE
2013-07-26 04:44:52

April Flowers for redOrbit.com - Your Universe Online The small celestial bodies orbiting between the sun and Jupiter and Neptune are known as centaurs, and their true identity has been one of the enduring mysteries of astrophysics. Previously, scientists have questioned, are they asteroids or comets? A new study, published in the Astrophysical Journal, using observations from NASA's Wide-field Infrared Survey Explorer (WISE) finds most centaurs are comets. Astronomers have been unsure...

NASA Traces Evolution Of Asteroid Families
2013-05-30 11:54:27

Brett Smith for redOrbit.com - Your Universe Online Using the orbiting Wide-field Infrared Survey Explorer (WISE), NASA scientists have been able to identify and categorize 28 new asteroid families found in the main belt between Mars and Jupiter, the space agency announced. Infrared snapshots from the asteroid-hunting section of the survey, called NEOWISE, allowed scientists to spot and sort thousands of previously hidden and uncategorized asteroids into families. "NEOWISE has given...

Asteroid Tracking Sensor Passes Key Test
2013-04-16 07:07:54

April Flowers for redOrbit.com - Your Universe Online A critical design test for an infrared sensor that could improve NASA's future ability to detect and track asteroids and comets has been passed. The Near Earth Object Camera's (NEOCam) performance in an environment that mimicked the temperatures and pressures of deep space were assessed by the test. NEOCam will be the key instrument for a proposed new asteroid-hunting space-based telescope for which design and capability details have...

Closest Star System In A Century Found 6.5 Light Years Away
2013-03-11 16:28:34

Brett Smith for redOrbit.com - Your Universe Online Using data obtained from a NASA satellite, a Pennsylvania State University astronomer has identified the closest solar system to be found within the past 97 years. According to astronomer Kevin Luhman´s report in the Astrophysical Journal Letters, the newly identified system is a pair of brown dwarf stars and the third-closest system to the Sun. “The distance to this brown dwarf pair is 6.5 light years -- so close that...

WISE Captures The Heat From Orion's Sword
2013-02-06 09:58:22

NASA's Jet Propulsion Laboratory The tangle of clouds and stars that lie in Orion's sword is showcased in a new, expansive view from NASA's Wide-field Infrared Survey Explorer, or WISE. Orion, the famous hunter, is visible in evening skies throughout the world from about December through April. The constellation appears tranquil and still to the naked eye, but lying in its sword, at what appears to be a slightly fuzzy star, is a turbulent cauldron of stellar birth. WISE scanned the...

Far Out Dude! Zeta Ophiuchi Making Waves In Space
2012-12-20 06:34:42

redOrbit Staff & Wire Reports - Your Universe Online NASA's Spitzer Space Telescope has captured an infrared image of the glowing waves given off by a giant star that was sent hurtling through space after its companion star exploded. Zeta Ophiuchi, the star which is currently speeding through the universe and leaving what is known as a bow shock in its wake, is 20 times more massive and 80,000 times brighter than our sun, according to the US space agency. Scientists believe that...
