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...
Dark matter could be a type of matter in the universe that does not emit, absorb or reflect detectable light and appears to interact very weakly with regular matter. Although physi...
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...
Seven billion light-years from Earth, there is an unexpected cluster of galaxies. It has two regions in the process of colliding with each other with a combined mass of more than t...
Galaxies can create many of the same stellar stream distortions that astronomers have looked to as possible signs of dark matter. Astronomers have long hoped that gaps, bends, and...
A mysterious signal deep underground may offer LUX-ZEPLIN its most intriguing clue to dark matter yet. For nearly a century, scientists have been trying to identify dark matter, th...
A distant quasar’s distorted images could hold clues to what dark matter is made of. Simulations of dark matter behaving like waves now offer a closer match to where those images a...
Cross-disciplinary research at Perimeter Institute and University of Maryland shows that dark photons could be lurking in more places than previously thought.
Pulsar Timing Arrays have been used to observe the background of gravitational waves in our galaxy. We aren't certain of their origin, but a new study shows a strong source could b...
For decades, astrophysicists have told us that the Milky Way sits inside a huge halo of dark matter. But new measurements of how the outer stars of our galaxy move don't seem to fi...
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
Dark matter is an invisible substance that is said to bind the universe; scientists may have found new signs of it.
The discovery might pave the way for answering one of the biggest unresolved questions about our universe
By Jacopo Prisco, CNN (CNN) — An international team of scientists says it has detected an intriguing signal that could hint at evidence of dark matter, offering a clue that might b...
The El Gordo supercluster is unusually large given its distance. How could such a large galaxy cluster form so quickly? The answer could be that dark matter is self-interacting in...
Galactic simulations show stellar streams develop dark-matter-like irregularities without dark matter clumps, helping distinguish false signals from real ones.
Astrophysicists from The University of Hong Kong (HKU), working with a research team led by Beijing Normal University (BNU), have developed a more physically realistic approach to...

Over a decade ago, the Fermi satellite detected an excess of gamma-ray emissions in the galactic center. Potential explanations included Sgr. A*, the Milky Way's SMBH, pulsars, and...
The world’s biggest dark matter search saw a particle it cannot explain
Insider Brief PRESS RELEASE — For decades, physicists have searched for dark matter, the invisible substance thought to make up roughly 85% of all matter in the universe. Although...
The dark matter search LUX-ZEPLIN has announced that they have made a detection that could be the first ever evidence for a dark matter particle. Just what have they measured, what...
Most of the stars in our Milky Way galaxy sit neatly on a flat plane. But the space around our galaxy is much more chaotic. Rogue bands of stars called "stellar streams" orbit the...
