Astronomers are constantly on the hunt for ever-colder star-like bodies, and two years ago a new class of such objects was discovered. However, until now no one has known exactly how cool their surfaces really are -- some evidence suggested they could be room temperature. A new study shows that while these brown dwarfs, sometimes called failed stars, are warmer than previously thought with temperatures about 250-350 degrees Fahrenheit.
