WISE Sub-brown dwarfs

Edward Wright, a University of California, Los Angeles, astronomer who serves as principal investigator for the Wide-field Infrared Survey Explorer (WISE), said in a talk Monday that the spacecraft has already discovered at least two cool, substellar objects known as brown dwarfs.
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 neighbourhood 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."
