Saturn’s rings are iconic, but new evidence presented by researchers from Monash University suggests Earth might once have sported one of its own. This ring would likely have caused climate chaos on the surface.

After almost five decades sailing through space, NASA is trying to squeeze a few more years out of the venerable Voyager 1 deep space probe by swapping a wonky thruster system for a disused secondary one to keep its radio antenna pointing at the Earth.

After five days in orbit, the Polaris Dawn mission, which conducted the world's first commercial spacewalk, has returned safely to Earth. At 3:36 am EDT, the Dragon capsule Resilience splashed down off the coast of the Dry Tortugas, Florida.

The Sun is the biggest fish in our small pond of a solar system, but it’s a mere minnow compared to the whales that dwell out in the cosmos. New telescope images show a gigantic star casually blowing bubbles 75 times bigger than our Sun.

The world's first private spacewalk has been completed. On September 12, 2024 at 7:58 am EDT, two of the four-person crew of the SpaceX Dragon spacecraft Resilience returned after a 106-minute tethered EVA 732 km (455 miles) above the Earth.

Our solar system might still bear the scars from an extremely close shave with an alien star. Such an encounter – the closest pass we know of – would have shaken up objects on the outskirts and might even mean there’s no Planet Nine after all.

Having completed its first day in orbit, the Polaris Dawn mission is preparing to make the first private spacewalk in history. Two astronauts are scheduled to exit the Dragon spacecraft Resilience at 2:23 am EDT and here's how to watch.

The most ambitious private space mission yet, which will see the first private spacewalk, has lifted off. At 5:23 am EDT, the Polaris Dawn mission rose from Launch Complex 39A at NASA’s Kennedy Space Center atop a Falcon 9 rocket for low-Earth orbit.

In an experiment that sounds about as safe as bobbing for fries, ESA carried out the first-ever 3D metal printing in space aboard the International Space Station (ISS). Built with Airbus, the Metal 3D Printer completed the first of four test shapes.

SpaceX founder Elon Musk says that the first of his company's Starship spacecraft will set off for Mars in two years and the first crewed missions will follow in 2028. He sees this as part of his plan to make humanity an interplanetary species.

The ill-fated Starliner spacecraft has returned from Earth at the end of a 93-day mission that was only supposed to last eight days. The empty capsule landed safely on September 7, 2024 at 12:01 am EDT at the White Sands Space Harbor in New Mexico.

The largest moon in our solar system may have been knocked off its axis and cracked like an egg four billion years ago by an asteroid bigger than the one that wiped out the dinosaurs on Earth at the end of the Cretaceous age.

The "not stranded" astronauts on the International Space Station (ISS) won't have an emergency ride home after Friday. NASA says that the uncrewed Starliner capsule will undock and return to Earth autonomously. Oh, and it might be 'haunted.'

The FAA has grounded SpaceX's Falcon 9 rocket after one failed during a powered landing attempt on August 28, 2024 after the successful launch of 21 Starlink satellites. It's the first unsuccessful landing for SpaceX since 2021.

Astronomers have watched a supermassive black hole take two bites of a star, and predicted when it might go back for a third. If it does, this should make for an intriguing stellar light show.
