The game is afoot! Astronomers may have found some of the universe’s missing matter, thanks to one team’s cosmic detective work. The case has been open for more than 20 years. In the 1990s and early ...

New research suggests that dark matter decay could have helped black holes grow to monstrous supermassive sizes relatively early in the infant universe. If true, this could help explain some of the ...

For more than half a century, scientists have tried to understand dark matter—a mysterious form of matter that doesn’t emit or absorb light but is thought to make up most of the universe’s mass. Its ...

Astronomers using observations from the NASA/ESA Hubble Space Telescope and NASA’s Chandra X-ray Observatory have studied how dark matter in clusters of galaxies behaves when the clusters collide. The ...

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 ...

There are excesses of gamma-ray emissions from the center of the Milky Way that are not fully understood. It has been hypothesized that dark matter could be responsible for it, though there has not ...

A black hole is more than just a region of space where nothing escapes. It can also become a powerful cosmic engine. When matter spirals inward, falling into its grasp, the black hole doesn't just ...

Dark matter, the mysterious substance that makes up roughly 80 percent of all the matter in the universe, may have been forged before our cosmos was even born. Scientists have long theorized as to ...

Astronomers have long been puzzled by two strange phenomena at the heart of our galaxy. First, the gas in the central molecular zone (CMZ), a dense and chaotic region near the Milky Way's core, ...

It is impossible for a telescope to image and far from being completely understood, yet dark matter is everywhere. The deepest mysteries about dark matter relate to its nature and behavior. The ...

There’s a new twist in the hunt for dark matter, the invisible substance believed to make up 85 percent of all the mass in the universe: it may actually be way lighter. In a study published in the ...
