To curious aliens, Earth would stand out as living planet

GAINESVILLE, Fla. -- With powerful instruments scouring the heavens, astronomers have found more than 240 planets in the past two decades, none likely to support Earth-like life.

But what if aliens were hunting life outside their own planet? Armed with telescopes only a bit bigger and more powerful than our own, could they peer through the vastness of space and lock in onto Earth as a likely home to life?

That's the question at the heart of paper co-authored by a University of Florida astronomer that appeared this week in the online edition of Astrophysical Journal. The answer, the authors say, is a qualified "yes."

With a space telescope larger than the Hubble Space Telescope pointed directly at our sun, they say, "hypothetical observers" could measure Earth's 24-hour rotation period, leading to observations of oceans and the chance of life.
