redOrbit Staff & Wire Reports - Your Universe Online Researchers from University College London and the University of New South Wales have reportedly developed a new, more powerful and more accurate way to detect extraterrestrial life that focuses on methane. Writing in the latest edition of the journal Proceedings of the National Academy of Sciences (PNAS), the study authors explain their development of a new spectrum for hot methane capable of detecting the molecule at...

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...

NASA's WISE Spacecraft Has Yet To Uncover Planet 'X' Beyond Pluto

redOrbit Staff & Wire Reports - Your Universe Online While NASA’s Wide-Field Infrared Survey Explorer (WISE) has uncovered thousands of new stars during its multi-year mission, it has been unable to collect any evidence supporting the supposed existence of a large but unseen celestial body believed to be located somewhere beyond Pluto’s orbit. This supposed celestial body is commonly referred to as “Planet X” -- alternatively “Nemesis” or “Tyche." However, despite the...

WASHINGTON, March 7, 2014 /PRNewswire-USNewswire/ -- After searching hundreds of millions of objects across our sky, NASA's Wide-Field Infrared Survey Explorer (WISE) has turned up no evidence of the hypothesized celestial body in our solar system commonly dubbed "Planet X." http://photos.prnewswire.com/prnvar/20081007/38461LOGO Researchers previously had theorized about the existence of this large, but unseen celestial body, suspected to lie somewhere beyond the orbit of Pluto. In...

Brown Dwarf Weather Map

Lee Rannals for redOrbit.com - Your Universe Online Scientists using the Very Large Telescope (VLT) at the European Southern Observatory created the world’s first map of the weather on the surface of a brown dwarf. The international team developed a map featuring the dark and light features of WISE J104915.57-531906.1B, which is the nearest brown dwarf to Earth. This brown dwarf, informally known as Luhman 16B, is one of two recently discovered brown dwarfs only six light years away...

John P. Millis, PhD for redOrbit.com - Your Universe Online One of the more interesting questions in astronomy surrounds how solar system objects actually form. Astronomers are particularly concerned about the boundary between a planet and a star. When examining the objects in our own solar neighborhood, the question seems trivial – the Sun dominates the mass of our system, while even the largest planet, Jupiter, is dwarfed by comparison. In other parts of the galaxy, stars exist that...

Storms As Big As Jupiter's 'Great Red Spot' Found On Brown Dwarfs

[ Watch the Video: Torrential Storm Clouds On Brown Dwarfs ] Lee Rannals for redOrbit.com - Your Universe Online Most brown dwarfs may contain storms as big as Jupiter’s “Great Red Spot,” according to findings presented at the American Astronomical Society in Washington. Brown dwarfs are a form of star, but lack the mass to fuse atoms continually to turn themselves into a full-fledged star. The celestial bodies are like a cross between a Jupiter-sized gas planet and a star....

Ancient Brown Dwarfs

John P. Millis, PhD for redOrbit.com - Your Universe Online The galaxy is a diverse place, containing stars, planets, nebulous gas, black holes, and all matter of other objects, some of which we still do not understand. But among this vast array sits an object that is neither a star, nor a planet. These brown dwarfs have masses only a fraction of that of our Sun, but are still at least 13 times more massive than Jupiter. But because of the lack of substantial fusion, the surface of...

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...

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...
