Leonid Meteor Shower: Sowing the Seeds of Life?

Data from instruments flown on airplanes during last year’s Leonid meteor shower show that the seeds of life, long suspected to exist in comet dust, could have survived a fiery passage from space to Earth’s ancient atmosphere. A range of findings, reported by an international team of NASA-led scientists, provide support for panspermia, which holds that life on Earth did not spring up spontaneously out of some primordial soup, but was instead seeded from space.
