Dark Matter

Despite making up most of the matter in the universe, dark matter doesn't interact with light. So how do astronomers know it is there?

The mapping of matter in the cosmos helps to confirm Einstein's theory of general relativity and reveals more about mysterious dark matter.

Europe's newest space telescope is set to cross the ocean ahead of its planned launch atop a SpaceX Falcon 9 rocket this summer.

Scientists watched as two stars slowed in their orbits around black holes, concluding it was the result of "drag" generated by dark matter.

The James Webb Space Telescope (JWST) has dazzled us plenty already, but the best is yet to come from the observatory, mission team members say.

The European Space Agency (ESA) recently announced a new mission of its science program: a small telescope orbiting the Earth dubbed Arrakhis.

Space probes that fly close to the sun may help reveal the nature of dark matter, which makes up about five-sixths of all matter in the universe but remains a mystery.

Scientists may have explained the mysterious distribution of small satellite galaxies around our Milky Way that has long puzzled astronomers, but not everyone is in agreement.

There simply isn't enough normal matter to account for the amount of gravitational force needed to hold the universe together, meaning dark matter must be prevalent.

A model of exotic dark matter suggests that the first stars may have formed not as individuals, but as tiny pockets embedded in gigantic, pancake-like sheets.

Meteor-hunting methods could be adapted to hunt for dark matter, the mysterious substance that makes up around 85% of the universe's matter but remains invisible.

Two decades' worth of observations of supernova explosions and a powerful new analysis tool has provided the most accurate accounting of dark energy and dark matter to date.

A machine-learning algorithm has helped astronomers discover thousands of gravitational lenses predicted by Einstein.

One hypothesis for the nature of dark matter is that some of it could be self-interacting, meaning the individual particles interact slightly with one another.

Scientists think that when dark photons collect around black holes, they can get trapped and boosted to high energies, where they might transform into other particles (or even just normal photons).

It's true that the dark matter hypothesis has its shortcomings — and, of course, we haven't found any dark matter particles yet. But the truth is that the alternatives are much worse.

A new hypothesis proposes that a large fraction of dark matter may be bound up inside tight balls the size of Neptune — so-called dark matter planets.

Using a cosmic relic from the universe's earliest moments researchers have made the earliest detection of a mysterious form of matter that makes up 85% of the universe's mass.

Observations across a vast range of scales are much better explained in an alternative theory of gravity requiring no invisible matter.

The LUX-ZEPLIN experiment has delivered its first results which show it to be the most sensitive dark matter detector to date.
