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.

Congratulations to NASA's Kepler mission team on their announcement of the discovery of its first five exoplanets (planets around other stars).

I think if you polled most space fans about their favorite moons of Jupiter, Ganymede would come in a consistent third behind Europa and Io. It's just not fair.
