A team of four NASA spacecraft finally caught sight of a phenomenon scientists have been hunting for years: an interplanetary shock.
This is one of the most tangible pieces of evidence yet for the idea that explosive volcanism was more common on early Mars.
A space rock called Bennu is getting its close-up: NASA's OSIRIS-REx mission to explore the asteroid has entered a new phase of detailed survey work.
It's still unclear how the dramatic operation went. But the hope is the explosive-packed bomb cut an artificial crater into Ryugu.
On a distant space rock being explored by a NASA probe, days are slowly shortening — and scientists are still trying to figure out why.
