EDINBURGH, Scotland, April 16 (UPI) -- If there is life on Mars it may be lurking in craters formed by asteroid impacts on the planet's surface, as has happened on Earth, Scottish scientists say.
Researchers at the University of Edinburgh said organisms have been found living deep beneath a site in Chesapeake Bay in the United States where an asteroid crashed 35 million years ago, suggesting crater sites on other planets may be "hiding life."
