This ancient interstellar dust formed the Earth and the solar system.
Particles collected from Earth’s upper atmosphere, originally deposited by comets, are older than our Solar System, scientists say – and these fine bits of interstellar dust could teach us about how planets and stars form from the very beginning.
These cosmic particles have lived through at least 4.6 billion years and travelled across incredible distances, according to the new research into their chemical composition.
