NASA’s DART mission lofted a swarm of boulders into space

Many of the newly liberated rocks will eventually go into their own orbit around the sun

A trail of dust extends from the asteroid Dimorphos (bright object at left in this Hubble telescope image), which now has 37 previously unseen boulders (circled) traveling alongside it.


When a probe smashed into a small asteroid last year, the collision did more than change the asteroid’s orbit — it blasted a few dozen hefty boulders into space too.
