Scientists have a new theory about how life on Earth began and it's pretty incredible
Scientists have suggested that interstellar dust capable of transporting micro-organisms across the universe is the source of life on Earth.
A study led by the University of Edinburgh's Professor Arjun Berera has posited that bacteria and micro-animals, capable of surviving hazardous journeys through space, could be the source of life on our little blue planet.
An example of this remarkable space travel can be seen in Saturn's rings, where scientists at the European Space Agency say they have found evidence that of materials that originated on the neighbouring moon Enceladus.
According to Berera's study, hypervelocity space dust, which can travel at up to 70km per hour, is 'constantly bombarding the Earth'.
In the study Berera explained how the dust could be responsible for bringing life to Earth, and life on Earth to other planets.
