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.
Last summer, scientists announced the discovery of a dozen new moons orbiting Jupiter. But now comes the hard part: naming them.
SpaceX's famous "Starman" dummy onboard the inaugural Falcon Heavy launch is about to have some competition — from a new dummy, named Ripley, strapped into the company's first Crew Dragon capsule.
Say you need to prepare to shoot bullets into an asteroid and suck up the debris kicked up from the blast, then tuck it away for safekeeping.

'Oumuamua is long gone, but it's still leaving scientists guessing. A new explanation proposes that the strange object was a "monstrous fluffy dust aggregate" produced by a busted-up comet.
China has built the world's first robotic, partially submersible boat for launching sounding rockets — a technology that will help meteorologists better understand the atmosphere over Earth's oceans.
A NASA scientist has visited a four-year-old island that satellites watched rise out of the waters — a rare opportunity to see in person a new island that lasts more than a few months.
Americans across the Midwest and Northeast can agree on one thing — it's really, really cold this week — and a NASA satellite monitoring air temperatures confirms the sentiment.
Scientists think that they've spotted a rare, Jupiter-size black hole casually strolling through the Milky Way galaxy.
