I'm used to reading excellent articles by Emily, but this one I found to be of truly extraordinary interest:

WISE satellite already spots two brown dwarfs
QUOTE One of the brown dwarfs, dubbed WISE 2, appears to be as cold as any that are known. It may even be colder, Wright said, than the brown dwarfs recently found by the UKIDSS survey, which are estimated to be in the neighborhood of 500 Kelvin, but the exact temperature of WISE 2 is uncertain (as are the temperatures of the UKIDSS objects). WISE 1 is a bit warmer, Wright said: "We think this is about an 800-Kelvin object." Wright later said that whereas the spectra of WISE 1 and WISE 2 are unambiguous, the spacecraft has found many more objects that may also be brown dwarfs. Confirmation of those will await follow-up observations, which the group has proposed on the Spitzer Space Telescope. Distances to the two new brown dwarfs are not known, Wright added http://www.scientificamerican.com/blog/pos...o-br-2010-05-27 |
