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

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

Scientists may be just 15 years away from finally detecting dark matter thanks to a new kind of detector that acts like a “cosmic car radio.” Designed to pick up the elusive frequency of axions — hypo ...

An international team of astronomers has solved one of the longstanding cosmic mysteries by uncovering direct evidence of a ...

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

Scientists have designed a 'cosmic radio' detector which could discover dark matter in 15 years. Published today in Nature, scientists at King's College London, Harvard University, UC Berkley and ...

Astronomers have long struggled with a troubling puzzle: a significant portion of normal matter in the universe appeared to ...

Mysterious dark matter makes up 85 percent of matter in the universe, and of the remaining 15 percent, scientists couldn’t account for half—until now.

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.
