Rocky planets like Earth could be found around most sunlike stars in our galaxy, new research suggests, further raising hopes that scientists will someday find E.T. or at least primitive life beyond our solar system.
The finding is based on an analysis of dust around 309 stars with masses comparable to our sun.
NASA's Spitzer Space Telescope was able to detect the heat that radiated from the dust, "not unlike the smoke you'll see rising from chimneys around here in the Boston area on a cold day," said researcher Michael Meyer of the University of Arizona.
