Where is everybody? For decades that question was merely a part of physics legend, the kind of thing grad students overhear when their advisors take them out to dinner.

The “Wow!” signal has been etched red marker in the memory of advocates for the search for extraterrestrial intelligence (SETI) since its unveiling in 1977. To this day, it remains one of the most enigmatic radio frequency signals ever found. Now a new paper from a wide collection of authors, including some volunteers, provides some corrections, and some new insights, into both the signal and its potential causes.

A Ph.D. student and his supervisor at Imperial College London have developed a simple way to test for active life on Mars and other planets using equipment already on the Mars Curiosity rover and planned for future use on the ExoMars Rosalind Franklin rover.

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.
