Kepler has taught us that rocky planets are common

Rocky planets are probably a whole lot more common in our galaxy than astronomers previously believed—according to the latest release of Kepler Space Telescope data last week—a scenario that enhances the prospects for ...

3 Questions: Sara Seager on discovering a trove of new planets

NASA’s Kepler -- an orbiting, planet-finding telescope launched in 2009 -- has dramatically increased the discovery rate of planets around stars other than the sun, known as exoplanets. Before Kepler, there were a total ...

Kepler releases new catalog of planet candidates

Since science operations began in May 2009, the Kepler team has released two catalogs of transiting planet candidates. The first catalog (Borucki et al, 2010), released in June 2010, contains 312 candidates identified in ...

How common are earths around small stars?

(Phys.org) —The Kepler mission has revolutionized the study of exoplanet statistics by increasing the number of known extrasolar planets and planet candidates by a factor of five, and by discovering systems with longer ...

41 new transiting planets in Kepler field of view

(Phys.org)—Two newly submitted studies verify 41 new transiting planets in 20 star systems. These results may increase the number of Kepler's confirmed planets by more than 50 percent: to 116 planets hosted in 67 systems, ...

'Bare' super-earths offer clues to evolution of hot atmospheres

A group of astronomers from the Astrobiology Center, the National Astronomical Observatory of Japan, the University of Tokyo, and other institutes, discovered two rocky super-Earth exoplanets lacking thick primordial atmospheres ...

Chandra sees eclipsing planet in X-rays for first time

For the first time since exoplanets, or planets around stars other than the sun, were discovered almost 20 years ago, X-ray observations have detected an exoplanet passing in front of its parent star.

Astronomers help focus research in the search for another Earth

Using public data collected by NASA's Kepler mission, astronomers have catalogued the planet candidates that may be similar to our third rock from the sun. The tabulation of candidates will help astronomers focus their research ...
