A new article in National Geographic suggests that the chance that life is transported through space in meteorites is far greater than previously anticipated.
Did Slow Space Rocks Seed Life on Earth?
New model yields better odds for transfer of organisms among planetary systems.
If microorganisms could survive a journey through space inside meteoroids, could life from Earth be transferred to planets in other solar systems—or even vice versa? A new study suggests the possibility is much higher than scientists once thought.
Using computer simulations involving slow-moving rocks, scientists from Princeton University, the University of Arizona, and the Centro de AstrobiologÃ*a (CAB) in Spain concluded that Earth could have exchanged rocks trillions of times with planets from other planetary systems during the solar system's infancy.
