Citizen Scientists Discover Dozens of New Cosmic Neighbors in NASA Data

We’ve never met some of the Sun’s closest neighbors until now. In a new study, astronomers report the discovery of 95 objects known as brown dwarfs, many within a few dozen light-years of the Sun. They’re well outside the solar system, so don’t experience heat from the Sun, but still inhabit a region astronomers consider our cosmic neighborhood. This collection represents some of the coldest known examples of these objects, which are between the sizes of planets and stars.
