Searching for one planet, finding another

Posted by Konstantin Batygin on 2011/05/23 07:35 CDT

Some parallels exist between Odysseus' journey and the discoveries of exoplanets. What initially started out as a well-planned trip from Troy back to Ithaca, turned into a series of rather unfortunate events, with episodes of fighting Cyclops and having your crew turned into swine.

Are there more Titans than Earths in the Milky Way?

Posted by Emily Lakdawalla on 2011/04/14 11:30 CDT

Might there be many Titan-like planets and moons, with atmospheres and liquid methane rain, rivers, and lakes, across the galaxy?

Evaporating exoplanet

CoRoT-7b was the first unambiguously rocky planet to be discovered and was quite small, at under five Earth masses. But a press release issued today suggests that its history probably has little to do with Earth's.

Posted by Bruce Betts on 2010/01/04 12:06 CST

Congratulations to NASA's Kepler mission team on their announcement of the discovery of its first five exoplanets (planets around other stars). All five are "hot Jupiters," meaning that they are the sizes of the gas giants in our solar system, but are extremely close to their parent stars.
