European astronomers have made the first planetary discovery in the closest-to-Earth Alpha Centauri star system. Here is some information about the discovery, and insights from Yale Astronomer Debra Fischer, who leads another Alpha Centauri planet search partially supported by The Planetary Society.

A measurement of the Andromeda galaxy's proper motion shows it's coming directly at us, and will collide with the Milky Way in 4 billion years. The event will transform the appearance of our night sky.
