2 Planets Share the Same Orbit

Buried in the flood of data from the Kepler telescope is a planetary system unlike any seen before. Two of its apparent planets share the same orbit around their star. If the discovery is confirmed, it would bolster a theory that Earth once shared its orbit with a Mars-sized body that later crashed into it, resulting… » 2/25/11 2:30pm 2/25/11 2:30pm

Our galaxy is home to more than 50 billion planets...and 500 million…

The Kepler telescope discovered more than 1,200 planets in just one tiny corner of the Milky Way. Crunching the numbers, a conservative estimate says there should be at least fifty billion planets in the entire galaxy, and about 500 million of those should be inside the habitable zone. But how many of those planets… » 2/20/11 7:00am 2/20/11 7:00am

Kepler Telescope discovers 1200 new worlds...and at least five…

In fifteen years, astronomers have detected just over 500 planets orbiting other stars. Now, after less than two years in orbit, the Kepler telescope has more than tripled that figure, discovering more than 1,200 possible new worlds. Even better, at least 54 of them are in their star's habitable zone, and five of… » 2/03/11 10:45am 2/03/11 10:45am

Could extraterrestrial life be hiding out on red dwarf planets?

In the next two or three years, advances in NASA's Kepler telescope will allow astronomers to determine which planets outside our solar system could potentially sustain life. Exoplanets orbiting red dwarf stars are likely candidates for having Earth-like environments. » 7/04/10 1:41pm 7/04/10 1:41pm

Remarkable Styrofoam Planet Is Among Five New Exoplanet Discoveries

NASA's dedicated exoplanet hunter, the Kepler space telescope, has turned up five new planets. One of the planets is bigger than Jupiter but as light as styrofoam, and the findings only get crazier. » 1/07/10 1:00pm 1/07/10 1:00pm
