"No existing galaxy formation model within our standard cosmological paradigm can currently explain how this galaxy came to ...

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

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

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

The CMZ spans almost 700 light years and contains some of the most dense molecular gas in the galaxy. Over the years, ...

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

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

Astronomers have identified a new ultra-diffuse galaxy that appears to defy one of the fundamental assumptions of modern ...

An extremely bold hypothesis proposes transient temporal singularities remove the need for dark matter and dark energy.

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

If dark matter is creating positrons in the CMZ, those particles will eventually slow down and eventually annihilate with electrons in the environment, producing gamma-rays at exactly 511keV energy.

“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 ...
