Astrobiology: May 2011 Archives

Kepler's Astounding Haul of Multiplanet Systems, Harvard-Smithsonian Center for Astrophysics

"In particular, the Kepler systems with multiple planets are much flatter than our solar system. They have to be for Kepler to spot them. Kepler watches for a planet to cross in front of its star, blocking a tiny fraction of the star's light. By measuring how much the star dims during such a transit, astronomers can calculate the planet's size, and by observing the time between successive events they can derive the orbital period -- how long it takes the planet to revolve around its star."
