Exoplanet news, features and articles

How will we know when we've found another Earth?

TESS will have the ultimate view of the night sky from a perfect orbit around Earth.

NASA's next exoplanet-hunting mission is scheduled to launch today (April 16) atop a SpaceX Falcon 9 rocket, and you can watch the action live.

NASA's Kepler Space Telescope has been used to detect 219 new planet candidates, including 10 in the so-called habitable zones of the stars they orbit.

For the first time, researchers have detected an atmosphere around a planet just a little bit larger than Earth outside the solar system.

The discovery of exoplanets also slightly increases how much credence we give to the possibility of near-term human extinction. This because of a concept known as the Great Filter.
