Black holes that turn matter into energy could explain dark energy and answer two other cosmic questions. Now, the challenge ...

Our Milky Way galaxy may not have a supermassive black hole at its center but rather an enormous clump of mysterious dark matter exerting the same gravitational influence, astronomers say. They ...

Dark matter is one of the biggest puzzles in science. Although it makes up about 85 percent of all matter in the universe, it has never been directly observed. You can’t see it, touch it, or hold it ...

This artist’s illustration depicts a dwarf galaxy that hosts an active galactic nucleus — an actively feeding black hole. In the background are many other dwarf galaxies hosting active black holes, as ...

Black holes are eaters of all things, even radiation. But what if their rapacious appetites had an unexpected side effect? A new study published in Physical Review Letters suggests that black holes ...

Gravitational wave astronomy is starting to do more than confirm Einstein’s equations. It is turning into a precision tool for mapping the invisible, with theorists now arguing that ripples in ...

This new map is not only the most detailed view of the universe’s invisible scaffolding to date, it also allows astronomers to look deeper into cosmic history. Reading time 3 minutes Dark matter—the ...

The expolision of a black hole could explain the origins of a mysterious high-energy neutrino detected in 2023, as well as shedding more light on the mystery of dark matter in the process. In 2023, a ...
