Dark Matter

Does dark matter have an electric charge? No one's really wondered before, but researchers are exploring the possibility that some dark matter particles have a small electrical charge.

Physicists speculate that decaying neutrons may be producing particles unknown to science that make up the elusive dark matter.

Could alien life be hiding in the multiverse? New studies say, "sure!"

A measurement of the fine structure constant puts significant limitations on the existence of these dark partners to ordinary light particles.

Dark matter may actually be a scattering of primordial black holes that arose soon after the Big Bang as a result of instabilities in the Higgs field, according to a new theory.

Scientists have calculated an end date for the universe. Presuming there are no surprises, of course.

A ghostly galaxy has almost no dark matter.

Mysterious cosmic signals radiating from the center of our Milky Way galaxy are actually triggered by ancient stars, rather than dark matter, a new study shows.

The universe's early gas may have been cooled by interactions with dark matter.

Stars were lighting up the universe by just 180 million years after the Big Bang, a new study reports.

Recent Hubble Space Telescope findings suggest that the universe is expanding much faster than expected — and astronomers say the rules of physics may need to be rewritten to understand why.

The Xinjiang Qitai 110-meter Radio Telescope — QTT, for short — could help advance research on dark matter, gravitational waves, and extraterrestrial intelligence.

An incredible photo from the Hubble Space Telescope showcases an enormous galaxy cluster that weighs in at a whopping 3 million billion suns.
