Alien Bacteria Could Breed in Extreme 'Hypergravity'

• Space

If alien life is out there, it may be able to exploit more-extreme environments than scientists think, because huge gravitational forces don't seem to pose much of a problem for microbes.

Several different species of bacteria can survive and reproduce in "hypergravity" more than 400,000 times stronger than that of the Earth, a new study reports. The find suggests that alien life could take root in a wide range of conditions -- and that it could survive the high G-forces imposed by meteorite impacts and ejections, making the exchange of life between planets a distinct possibility.
