NASA Kepler mission

Flight controllers sent a final set of commands to the exoplanet-hunting Kepler spacecraft, shutting the spacecraft down after it finally ran out of propellant, ending a spectacular mission.

Astronomers reviewing data collected by the planet-hunting Kepler spacecraft have found evidence for a large exomoon orbiting a gas giant 8,000 light years away. If confirmed, it would mark the first detection of a moon in another solar system.
