Astronomers launch search for alien life on 86 possible Earth-like planets

Astronomers at the University of California, Berkeley are aiming a radio telescope to detect signals of alien life on 86 possible Earth-like planets.

The search began on Saturday, May 8, when the Robert C. Byrd Green Bank Telescope - the largest steerable radio telescope in the world - dedicated an hour to eight stars with possible planets.

The colossal dish will gather 24 hours of data on each of the planets, which have been selected from a list of 1,235 planets identified by NASA's Kepler space telescope.

The Green Bank telescope will stare for about five minutes at stars in the Kepler survey that have a candidate planet in the star's habitable zone-that is, the planet has a surface temperature at which liquidater could be maintained.
