Can some supernovas explode twice?

Nebulas are perhaps as famous for being identified

Many people like to check that they have walked 10,000 steps over the course of a day, but falling short of that target still seems to bring serious health benefits

Japan's Himawari-8 and Himawari-9 satellites, designed to study weather here on Earth, have also been quietly collecting valuable data on Venus for nearly a decade, scientists recently discovered.

Purdue University's new Neil Armstrong Space Prize, named for the school's most famous astronaut-alum, will honor achievements in "space discovery, innovation and human achievement."

Late Cretaceous dinosaur tracks found in Canada might have been made by different species walking together, but the evidence is far from conclusive

The Tianzhou 9 freighter arrived at China's Tiangong space station last week, packed with supplies. Watch its arrival in this video.

Researchers working with China's Five-hundred-meter Aperture Spherical radio Telescope (FAST) have revealed some of the complexity in a type of cloud in the ISM. They've detected a network of filaments in one Very High Velocity Cloud (VHVC). The observations hint at the complexity that can evolve in these clouds, all without the influence of gravity.

To explore the unknown in deep space, millions of miles away from Earth, it’s crucial for spacecraft to have ample power. NASA’s radioisotope power systems (RPS) that rely on are a viable option for these missions and have been used for over 60 years. Now, NASA is testing a new type of RPS fuel that could become an additional option for future long-duration journeys to extreme environments.

Astronomers have discovered an extraordinary world that defies everything we thought we knew about planets. TOI-2431 b, an Earth sized planet located just 117 light years away, races around its star so fast that it experiences over 1,600 "years" in the time it takes Earth to complete just one orbit. The discovery of this extreme world, with its distorted shape and ultra dense composition, is revolutionising our understanding of planetary systems and revealing just how bizarre and diverse worlds beyond our Solar System can be.

Black holes played a critical role in the formation of the early universe. However, astronomers have been debating for a long time just how critical, as the information we had about early black holes, which exist at high red-shifts, was relatively limited. A new paper from a group of researchers led by Sophia Geris at the University of Cambridge combined several spectra from the James Webb Space Telescope (JWST) to add some context to the formation of black holes early in the universe, and found that there are plenty of smaller ones lurking around, and lending credence to the idea that black holes of all sizes contributed to the formation of our modern universe.
