Closest Star System Found

It's called WISE J104915.57-531906 - a pair of brown dwarfs located only 6.5 ly away (so close that Earth's television transmissions from 2006 are now arriving there). This system is the third-closest star system to the Sun!

The star system is named "WISE J104915.57-531906" because it was discovered in a map of the entire sky obtained by the NASA-funded Wide-field Infrared Survey Explorer (WISE) satellite. It is only slightly farther away than the second-closest star, Barnard's star, which was discovered 6 ly from the Sun in 1916. The closest star system consists of Alpha Centauri, found to be a neighbor of the Sun in 1839 at 4.4 ly, and the fainter Proxima Centauri, discovered in 1917 at 4.2 ly.

New star system found:



A star HR 8799 with 4 planets (hot and toxic).

HR 8799's system, which is 128 ly away from Earth, is one of only a couple of these stars that have been imaged, and the only one for which spectroscopy of all the planets has been obtained. These warm, red planets are unlike any other known object in our universe. All four planets have different spectra, and all four are peculiar.

That's really cool

Planets have "lukewarm" temperatures of about 1000 K, either have methane or ammonia, with little or no signs of their chemical partners. Other chemicals such as acetylene, previously undiscovered on any exoplanet, and carbon dioxide may be present as well. The planets also are "redder," meaning that they emit longer wavelengths of light, than celestial objects with similar temperatures. This could be explained by significant but patchy cloud cover on the planets.
