Deep-sea rocks packed with valuable metals may also be making oxygen in the deep, dark ocean—raising new questions about the cost of mining them.

The Starship megarocket checked every significant box during its 10th test flight on Tuesday evening (Aug. 26), according to SpaceX.

The NASA/ESA/CSA James Webb Space Telescope has revealed new details in the core of the Butterfly Nebula, NGC 6302. From the dense, dusty torus that surrounds the star hidden at the centre of the nebula to its outflowing jets, the Webb observations reveal many new discoveries that paint a never-before-seen portrait of a dynamic and structured planetary nebula.

Performing CPR on a space station in microgravity involves doing a handstand on a person's chest and pushing against the walls with your legs – but now researchers say there is a better way

Overcoming three recent failed tries, Elon Musk’s rocket company successfully flew its reusable jumbo booster and upper-stage Starship spacecraft

SpaceX's Starship megarocket took to the skies for the 10th time ever today (Aug. 26), on a bold test flight that marked a big bounceback from recent failures.

A comparison of the thylacine’s genome to other marsupials has revealed that the creatures lost genetic diversity long before humans and dingoes arrived in Australia

What are those curved arcs in the sky?

Europe's JUICE Jupiter probe lost contact with Earth for nearly a full day recently, but the problem was solved in time for its planned Aug. 31 Venus flyby.

Even if life never took hold on Ceres, the discovery could help broaden the range of environments that could potentially be habitable.

The rare sailback houndshark, which has an unusually large dorsal fin, was first described by scientists in 1973. That was the last record of its existence, until now

The dwarf planet is cold now, but new research paints a picture of Ceres hosting a deep, long-lived energy source that may have maintained habitable conditions in the past.

You know, if you think about it, and trust me we’re about to, the Moon is kind of weird.

How can thermoelectric generators (TEGs) help advance future lunar surface habitats? This is what a recent study published in Acta Astronautica hopes to address as a team of researchers from the Republic of Korea investigated a novel technique for improving power efficiency and reliability under the Moon’s harsh conditions. This study has the potential to help mission planners, engineers, and future astronauts develop technologies necessary for deep space human exploration to the Moon and beyond.

New analysis of human deep space communications suggests the most likely places to detect signals from an extraterrestrial intelligence.

How do you tell how old an astronomical object is? I mean, the next time the Moon is in the sky, take a look at it. How would you even begin to answer that question?

The 33rd SpaceX commercial resupply services mission for NASA, scheduled to lift off from the agency's Kennedy Space Center in Florida in late August, is heading to the International Space Station with an important investigation for the future of bone health.
