Just about 3 minutes ago NASA launched Kepler telescope. Kepler will search for life in our galaxy Milky Way. Kepler will monitor 100,000 stars, searching for signs of planets - including ones as small as or smaller than Earth. The telescope will continue the search for habitable planets.

Kepler is the first mission with the ability to find planets like Earth -- rocky planets that orbit sun-like stars in a warm zone where liquid water could be maintained on the surface. Kepler will search the Milky Way galaxy for habitable life. "There may be 100 billion Earth-like planets in the Milky Way, or one for every sun-type star in the galaxy," said Alan Boss to CNN, an astronomer with the Carnegie Institution and author of a new book.
