Astronomers have stumbled upon yet another ghostly galaxy that appears to be devoid of dark matter, the elusive stuff that ...

Mysterious dark matter makes up 85 percent of matter in the universe, and of the remaining 15 percent, scientists couldn’t ...

Astronomers have long been puzzled by two strange phenomena at the heart of our galaxy. First, the gas in the central ...

"We don't know the frequency, so we need to keep tuning and trying different ones, like searching for a good radio station ...

The detection of dark matter, the elusive type of matter predicted to make up most of the universe's mass, is a long-standing ...

Published in Nature, scientists at King's College London, Harvard University, UC Berkeley and others have shared the ...

The rotating disk galaxy, mostly made up of dark matter, was discovered within a larger cloud of fast-moving hydrogen gas.

A blob of gas seen outside the Milky Way could be a type of starless, dark matter–dominated galaxy. Some scientists are skeptical.

The axion quasiparticle forms when the interaction between the electric field and magnetization oscillates in a specific ...

A long-elusive, hypothetical subatomic particle called the axion can be simulated and potentially detected in a type of thin material.

Physicist Richard Lieu first explored the idea that gravity could exist without mass—now he’s got a new cosmological model ...

“If dark matter is a wave, then it's just oscillating up and down, so the way you try and detect it is you look for that oscillation, just like we looked for the oscillation of the axial quasiparticle ...
