NASA smacked a spacecraft into an asteroid – and learned details about its 12-million-year history

Five new studies published in Nature Communications journal today have used the images sent back from DART (Double Asteroid Redirection Test) and its travel buddy LICIACube to unravel the origins of the Didymos-Dimorphos dual asteroid system. They’ve also put that data in context for other asteroids out there.
