Scientists locate 5 stars capable of housing ET life

US astronomers have come up with a short list of five stars in the Milky Way galaxy that are most likely to support extraterrestrial life.
The stars were chosen based on a number of criteria, including size, composition, age and colour, that would make them similar to the sun and enable planets resembling Earth to orbit them, said Margaret Turnbull of the Carnegie Institution of Washington.
Turnbull's list would enable astronomers to point telescopes towards the stars with the most potential of sending radio signals from extraterrestrial life.
"These are places I would want to live if God were to put our planet around another star," Turnbull said on Saturday at a conference of the America Association for the Advancement of Science in St Louis, Missouri.
The list was developed to guide the use of NASA's new powerful orbiting observatories, or the Terrestrial Planet Finder, which will search for Earth-like planets.
"There are 400 billion stars in the galaxy, and obviously we are not going to point the Terrestrial Planet Finder at every one of them," Turnbull said.
Among the most promising sun-like stars was beta CVn, about 26 light years from Earth in the constellation Canes Venatici.
