A five-year study of data from the Kepler space observatory has found that over half the possible planets it has identified are either eclipsing binary stars or brown dwarfs.

But the Kepler Observatory was designed to point at the same spot and stare for years and capture a constant stream of images, which is how the telescope was able to catch planets as they moved in ...

The Kepler mission team released a survey of 219 potential exoplanets that had been detected by the space observatory launched in 2009 to scan the Milky Way galaxy.

NASA's 4-year-old Kepler spacecraft isn't the only observatory searching for alien planets. See which new spacecraft are waiting for their chance to hunt for exoplanets.

Kepler has detected 3,548 candidate planets to date, 135 of which have been confirmed by follow-up observations. Mission scientists expect more than 90 percent of the observatory's finds will end ...

Engineers-turned-first responders nursed NASA’s planet-hunting Kepler observatory back to stable condition after it unexpectedly slipped into emergency mode 75 million miles from Earth last week ...

The planet orbits a star nearly 3,000 light-years away and was discovered using the Kepler observatory, which looks for telltale dips in star light as a planet orbits a star; if the planet’s ...

NASA's Kepler spacecraft has sent back 43 days-worth of data from its search for Earth-like planets.

Using data from the Kepler space observatory, scientists at the Harvard-Smithsonian Center for Astrophysics and SETI have discovered for the first time a planet orbiting a binary star system ...

NASA's Kepler space observatory has found more than 1,200 potential alien worlds since it began hunting for extrasolar planets in 2009.

Despite some failed parts, NASA's orbiting Kepler observatory, which specialized in finding Earth-like planets, has been given a new to-do list that should keep it in the planet-hunting game.
