Cold brown dwarfs blur line between stars and planets

But until now, no one knew exactly how cool the bodies’ surfaces really are. In fact, some evidence suggested they could be at room temperature. A new …
Kepler discovers smallest planet yet
NASA’s Kepler mission scientists have discovered a new planetary system that is home to the smallest planet yet found around a star similar to our sun. The planets are located in a system called Kepler-37, about 210 light-years from Earth in the constellation Lyra. The smallest planet, Kepler-37b, is slightly larger than our moon, measuring …
Hubble image of Carina Nebula, NGC 3372
Shown here is a 50-light-year-wide view of the central region of the Carina Nebula where a maelstrom of star birth — and death — is taking place within the Milky Way Galaxy. This image is a composite of many separate exposures made by the ACS instrument on the Hubble Space Telescope along with ground-based observations. …
