Scientists working with the Gemini North and Keck II telescopes have discovered a galaxy that's made from 99.99% dark matter. And they noticed it because it was "fluffy." Share on Facebook (opens in a ...

"It's a fairly unusual question to ask in the scientific world, because most researchers would agree that dark matter is dark, but we have shown that even dark matter that is the darkest kind ...

Recent scientific proposals suggest that dark matter, the elusive substance comprising much of the universe’s mass, might not be entirely “dark” as it could interact with light by leaving detectable ...

Researchers suggest that dark matter might subtly color light red or blue as it passes through, revealing traces of its existence. Using a network-like model of particle connections, they argue that ...

Dark matter is one of nature's most confounding mysteries. It keeps particle physicists up at night and cosmologists glued to their supercomputer simulations. We know it's real because its mass ...

Smooth filaments stretching for many light-years, seen by the powerful space telescope, could indicate what the right "recipe" is for dark matter.

UC Santa Cruz physicist Stefano Profumo has put forward two imaginative but scientifically grounded theories that may help solve one of the biggest mysteries in physics: the origin of dark matter. In ...

A researcher identified gamma ray emissions that appear to have originated from dark matter, but other physicists still aren’t convinced. Reading time 4 minutes Astronomers have spent nearly a century ...

In recent years, a curious hypothetical particle called the axion, invented to address challenging problems with the strong nuclear force, has emerged as a leading candidate to explain dark matter.

Dark matter, one of the universe's best kept secrets, may have been quietly painting the cosmos in faint, detectable hues of red and blue all along, a new study suggests. Dark matter makes up more ...
