Now, just when scientists are "finding and greet" the new neighbors, WISE has a surprise in the room: there are many fewer stars brown around us predicted.
"This result is really enlightening," said Davy Kirkpatrick WISE science team. "Now we're finally exploring the solar neighborhood with infrared vision, small is not as prevalent as we thought." Previous estimates had predicted as many brown dwarfs as stars Typical, but the new initial count WISE shows only six brown dwarf stars. It is the cosmic equivalent to finally be able to see a mysterious gated and found there only a few houses.
