Remnants of an ancient swamp have been found preserved inside glass created during a meteorite strike. The discovery marks the first time that traces of life have been found to survive the heat and pressure of an impact, adding weight to arguments that microbes travelling on space rocks could have seeded the solar system.

Astrobiologists have long suggested that simple life forms could have hitched a ride to Earth inside meteors, or that impacts on early Earth could have sent terrestrial microbes to other worlds on ejected pieces of our planet. We know that rocks kicked up by impacts can travel vast distances. Martian meteorites with soil trapped inside have landed on Earth, and theoretical calculations suggest that meteor strikes on Earth could have had enough energy to send rocks as far away as the moons of Jupiter and Saturn.
