Planet Quest
HALIFAX, NOVA SCOTIA, CANADA – Less than a decade ago, there was no proof of planets orbiting any star other than our own sun. (No proof on Earth, anyway.) Today, there are more than 50 extrasolar worlds catalogued, and things are just getting started. NASA’s new Planet Quest site tracks fresh discoveries, explains detection techniques, and describes future missions as the universe starts to get just a little more crowded.
