NASA was forced to plan for the inevitable death of the exoplanet-hunting Kepler space telescope a few weeks ago. The spacecraft, which had already discovered literally thousands of new planets ...

An unusual planetary system with three known ultra-low density 'super-puff' planets has at least one more planet, according to new observations.

Since its launch in March 2009, the Kepler Space Telescope has provided us with an incredible amount of data about exoplanets within our galaxy, proving these worlds are more varied and numerous ...
