Dark matter is some kind of substance that has gravity—it holds galaxies together—yet cannot be directly seen with any ...

A team of cosmologists in China has introduced a mathematical framework that investigates two of the deepest mysteries in ...

T he first time I heard about galaxies without dark matter, I was sitting in my very first graduate class at the University ...

This video explores the enigma of dark matter, an elusive substance believed to make up most of the universe's matter. While ...

First and perhaps most perplexingly, researchers remain unsure about what exactly dark matter is. Originally, some scientists conjectured that the missing mass in the universe was made up of small ...

The universe is overrun with dark matter, outweighing the ordinary stuff that stars and planets are made of five-to-one. But some corners of the cosmos are more dominated by the invisible substance ...

NASA said CDG-2 “may be among the most heavily dark matter-dominated galaxies ever discovered” NASA, ESA, Dayi Li (UToronto) A new galaxy, named Candidate Dark Galaxy-2 or CDG-2, was recently ...

Astronomers have spotted a galaxy so faint, it’s almost invisible — a discovery that could help illuminate one of the most elusive substances in the universe. The researchers found Candidate Dark ...

Astronomers have just identified what appears to be a cosmic anomaly: a faint galaxy with so few visible stars that, according to calculations, as much as 99.9 percent of its mass is dark matter. The ...

In context: While it is still considered a hypothetical theory, dark matter is being actively studied by scientists looking for novel cosmological clues. It does not interact with light or other types ...

Scientists using a trio of some of the world’s most powerful observatories, the Hubble Space Telescope, ESA’s Euclid, and the Subaru Telescope, have pulled back the curtain on a ghost galaxy that is ...

Dark matter doesn’t emit, absorb, or reflect light. It’s invisible but supposedly makes up 85% of the universe’s mass. Because it’s so abundant, astronomers believe it should explain many unsolved ...
