Efforts to limit ozone-depleting chemical compounds had a significant impact. The ozone hole over the Antarctic is significantly smaller in 2025 than in previous years, ranking as the fifth-smallest ...

Albert Einstein's theory of gravity, general relativity, may not be the best recipe to describe black holes. New research suggests future images of black holes could be precise enough to allow ...

Mathematical quirks of our universe have led some cosmologists to wonder whether the cosmos was actually born in a black hole. Parallels in the physics of the universe and that of black holes have led ...

Earlier this year, researchers reported the most massive black hole merger ever detected. But the event was so unusual that questions around its origin sowed confusion within the astrophysics ...

A series of about 5,200 holes stretching nearly a mile (1.5 kilometers) across the Pisco Valley in the southern Peruvian Andes has baffled researchers for nearly a century. But a fresh look at the ...

For decades, archaeologists have been perplexed by thousands of mysterious dimples dotting the landscape in southern Peru. Known as the “Band of Holes,” the depressions are arranged in a long, slender ...

No, it wasn’t built by aliens. But accountants? Maybe. Researchers used drones to get another look at the "Band of Holes" along Monte Sierpe, and their work suggests that the Inca may have ...

In 2023, scientists detected the gravitational waves from a black hole collision that seemed impossible. New research finally explains how this "forbidden" black hole came to be, and what it can teach ...

Astronomers using the James Webb Space Telescope (JWST) may have discovered the most distant supermassive black hole ever seen. The enormous object, hosted by the galaxy GHZ2, is so far away that ...
