NASA's Spitzer Space Telescope has detected infrared light emanating from 55 Cancri e, a dark, blazing-hot planet only twice the size of Earth and eight times as heavy. This marks the first time that light has been detected from a planet of such a small size, and the find is telling astrophysicists where to look in their search for signs of life on planets beyond our own.
