Six thousand eight hundred feet below the floor of an active nickel mine in northern Ontario, something has gone extremely ...

Scientists have discovered that dark matter, the universe's most mysterious "stuff," obeys gravity on vast cosmological scales. This could help to dismiss the possibility of a fifth fundamental force ...

Researchers may have identified what could be a compelling clue in the ongoing hunt to prove the existence of dark matter. A mysterious diffuse glow of gamma rays near the center of the Milky Way has ...

"Dark dwarfs" may sound like a new race of Sauron-worshipping Middle-Earth dwellers, but it's actually a new type of stellar body proposed to exist at the hearts of galaxies. The prefix "dark" here ...

In the early 1930s, Swiss astronomer Fritz Zwicky observed galaxies in space moving faster than their mass should allow, prompting him to infer the presence of some invisible scaffolding—dark ...

The first time I heard about galaxies without dark matter, I was sitting in my very first graduate class at the University of São Paulo. A team had found a small, strange galaxy that appeared to ...

Dark matter, one of the Universe’s greatest mysteries, may have been born blazing hot instead of cold and sluggish as scientists long believed. New research shows that dark matter particles could have ...

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, ...

Dark matter may be invisible, but scientists are getting closer to understanding whether it follows the same rules as everything we can see. By comparing how galaxies move through cosmic gravity wells ...
