Is there life on Mars? Rock may have answer
A rare, fist-sized meteorite from Mars has been found by scientists in the Oman desert and they are beginning to examine it for evidence of life on the red planet and other mysteries.
The rock is one of only 18 on Earth known to have come from Mars, the scientists said. Most of the others have been snapped up by collectors, so only a handful including the one found by the team are fully available for study.
