NASA's Kepler Mission Announces a Planet Bonanza, 715 New Worlds Multi_transits_many_full_0 Kepler Wed, Feb 26, 2014

NASA's Kepler mission announced the discovery of 715 new planets. These newly-verified worlds orbit 305 stars, revealing multiple-planet systems much like our own solar system.

Kepler Discovers its Smallest Habitable Zone Planets Pia17001-43 Kepler Thu, Apr 18, 2013

NASA's Kepler mission has discovered two new planetary systems that include three super-Earth-size planets in the "habitable zone," the range of distance from a star where the surface temperature of an orbiting planet might be suitable for liquid water.

Gravity-Bending Find Leads to Kepler Meeting Einstein Pia16885_ip Kepler Thu, Apr 04, 2013

NASA's Kepler space telescope has witnessed the effects of a dead star bending the light of its companion star. The findings are among the first detections of this phenomenon -- a result of Einstein's theory of general relativity -- in binary, or double, star systems.

NASA's Kepler Announces 11 Planetary Systems Hosting 26 Planets Keplermultiplanetsystems_sm Kepler Thu, Jan 26, 2012

NASA's Kepler mission has discovered 11 new planetary systems hosting 26 confirmed planets. These discoveries nearly double the number of verified planets and triple the number of stars known to have more than one planet that transits, or passes in front of, the star. Such systems will help astronomers better understand how planets form.

NASA's Kepler Mission Finds Three Smallest Exoplanets Artistconcept-sm Kepler Wed, Jan 11, 2012

Astronomers using data from NASA's Kepler mission have discovered the three smallest planets yet detected orbiting a star beyond our sun. The planets orbit a single star, called KOI-961, and are 0.78, 0.73 and 0.57 times the radius of Earth. The smallest is about the size of Mars.
