On the moon, the lack of atmosphere and accompanying features such as biological activity, oxygen-rich air, flowing water and rain, wind, and most erosion allows the lunar regolith to preserve a long-term record of surface processes in the space environment.

Our sun is a loner. It lacks a stellar companion hurtling through interstellar space with it. But we’ve known for a long time that that’s actually relatively rare—most stars have at least one gravitationally bound partner. Understanding how exactly those stars are related to each other is critical for observational campaigns—especially for those of exoplanets. […]

Astrophysicists think that black hole masses are hierarchical. The largest are supermassive black holes (SMBH) like the one at the center of the Milky Way and other galaxies. Stellar mass black holes are born of collapsing stars, and are smaller. The smallest of all are the theoretical primordial black holes, which only formed in the […]

Researchers have developed a novel virtual model for simulating how astronauts in future moon base operations might interact with each other and with their environment, with preliminary simulations revealing potential opportunities to boost the chances of a successful mission. Raymond Vera and colleagues at George Mason University in Virginia, U.S., present these findings in PLOS […]

On May 22, 2026, the Pentagon released a second batch of previously classified photos and videos showing what appear to be unexplained flying objects. These file dumps were the culmination of a process that was set in motion back in July 2023, when a group of government whistleblowers testified before Congress that the U.S. government […]

Researchers from the University of Glasgow’s Institute for Gravitational Research are celebrating the publication of a vast new treasure trove of gravitational wave detections, hailed as a milestone marking the coming of age of gravitational astronomy.

A large protocluster of galaxies that existed 12.6 billion years ago, first discovered with the Subaru Telescope, has been examined in detail using the James Webb Space Telescope (JWST). The study found that galaxies in crowded regions are more extended than similar galaxies in less dense environments. The results, published in The Astrophysical Journal Letters […]
