The flight of Artemis II has inspired a new generation of Americans to think about space, but even before NASA returned to ...

Dark matter keeps getting blamed for the universe’s big patterns while staying stubbornly out of reach. You cannot see it, touch it, or capture it. Yet its gravity helps shape galaxies, and that makes ...

Add Yahoo as a preferred source to see more of our stories on Google. If dark matter particles decay, then scientists could hunt for signs of this process, including X-ray or gamma-ray radiation or ...

Two kilometres underground near Sudbury, Ont. , a machine has reached a temperature so low it barely seems real.

A tiny object half a universe away, a scar in a stream of stars circling the Milky Way, and an unusual star cluster in a ...

A model of the cyclic universe suggests that dark matter could be a population of black holes predating the Big Bang.

Invisible dark matter particles may regularly pass through our bodies, and dozens to thousands of these particles may be colliding with atoms inside us every year, according to a new calculation.

Dark matter may consist of two particles, explaining why only the Milky Way shows a strange gamma-ray signal while smaller ...

A mysterious glow of gamma rays at the center of the Milky Way has long hinted at dark matter, but the lack of similar signals in smaller dwarf galaxies has cast doubt on that idea. Now, researchers ...

Dark matter makes up most of the universe’s mass, yet remains invisible and undetected directly. Scientists are probing its secrets through underground labs, quantum sensors, and space telescopes.

A new study suggests that failing to detect dark matter signals in some galaxies may not contradict evidence seen in our own.
