Astronomers using NASA's Hubble Space Telescope have found compelling evidence of a planet forming 7.5 billion miles away from its star

NASA's Hubble Space Telescope will have two opportunities in the next few years to hunt for Earth-sized planets

NASA is preparing the TESS observatory (Transiting Exoplanet Survey Satellite) to follow-up on the successes of the planet-hunting Kepler observatory

Astronomers using the Subaru Telescope in Hawaii recently discovered (pdf) a "super-Jupiter" orbiting the star Kappa Andromedae

Astronomers have detected an alien planet that may be capable of supporting life as we know it

A second look at data from NASA's Hubble Space Telescope is reanimating the claim that the nearby star Fomalhaut hosts a massive exoplanet
