`Asteroid impact stored proof of life in glasses on earth`

Whenever an asteroid or a comet hit the earth in the past, the impact melted tonnes of soil and rock, some of which formed glass as it cooled. Now, a thrilling discovery has found that these impact glasses stored the signatures of ancient life at the time of the impact.
