Dark matter continues to challenge astronomers as they work to solve the mystery of this so-far-unseen material that permeates the Universe. It's not that the stuff doesn't exist....
Dark matter is known to make up roughly 85% of all mass in the universe, as evidenced by the way galaxies spin and how galaxy clusters are held together under gravity. Yet despite...
Composing some 85% of the universe's total mass, dark matter betrays its presence only through gravity, unlike ordinary matter. Yet through new research published in Physical Revie...
Why giving dark matter an additional attractive force does not necessarily produce “clumpier matter.” Dark matter shapes galaxies and the large structure of the Universe through gr...
Scientists have discovered a rare star formation hidden in a distant galaxy, unlike anything seen before beyond the Milky Way. What’s more, the discovery offers a brand new way to...
The first globular cluster stellar stream found beyond the Milky Way shows that these faint structures can be used to study dark matter in other galaxies. A faint ribbon of stars s...
Dark matter is already one of the strangest substances in the universe, but a new study suggests this elusive material could be even weirder than we thought.
Dark matter is the invisible stuff that accounts for roughly 85% of the mass in the universe, and for decades, physicists have been trying to figure out what it's made of. Now an e...
Astronomers have discovered that the jet of a distant blazar has been gravitationally lensed by an unseen source of dark matter. Led by Silke Britzen at the Max Planck Institute fo...

Researchers spotted an unusual gamma-ray signal in three galaxy clusters, which may be a telltale sign of dark matter – or some even more exotic phenomenon
Dark matter is an invisible substance that is said to bind the universe; scientists may have found new signs of it.
The world’s biggest dark matter search saw a particle it cannot explain
If not, at the very least an extremely strange cosmic phenomenon.
Most of the matter in the universe is dark matter, but for decades physicists haven’t been able to directly observe it – that may have just changed
The discovery might pave the way for answering one of the biggest unresolved questions about our universe
The mysterious substance that binds galaxies together could naturally be 'in tune' with a hidden fifth dimension, according to a new theory aiming to shed light on one of science's...
The geometry of a hidden dimension may naturally explain dark matter resonance and its elusive behavior. Every galaxy appears to carry far more mass than telescopes can see. That i...
Cross-disciplinary research at Perimeter Institute and University of Maryland shows that dark photons could be lurking in more places than previously thought.
Researchers in South Dakota observed hints of it during a deep-underground experiment but stopped short of saying they finally detected this elusive cosmic component.
A ghostly ribbon of stars winding around a faint galaxy 115 million light-years away is giving astronomers a rare new way to trace one of the universe’s most elusive ingredients: d...
A jet erupting from a distant supermassive black hole-powered blazar is being gravitationally lensed by an unseen clump of dark matter, and that could tell us about the source of c...
Galactic simulations show stellar streams develop dark-matter-like irregularities without dark matter clumps, helping distinguish false signals from real ones.
An underground detector recorded a strange interaction pointing to a particle with some properties that signify dark matter. The detection is small but promising.
