sciencehabit writes: Shining just 25 light-years from Earth in the constellation Lyra, Vega is the fifth brightest star in the night sky. In 1983, astronomers discovered dust orbiting the star, suggesting it had a solar system, and Carl Sagan chose to make Vega the source of a SETI signal in his 1985 novel Contact. At the time, Vega was thought to be only about a couple hundred million years old, probably too young for any planets to have spawned life. Since then, however, estimates of Vega's age have increased to between 625 million and 850 million years old. So suitable planets have probably had sufficient time to develop primitive life.
