From the Milky Way's halo to the far reaches of the cosmos, the two dominating components of the universe are revealing more hints about themselves.
A team of astronomers claim to have the most compelling case for annihilating dark matter yet.
Dark matter was discovered 80 years ago when astronomer Fritz Zwicky spied a galaxy cluster whirling so fast, the galaxies were bound to fly apart unless something — something less luminous than ordinary stars or gas — held them together. Decades later, the scientific community concedes the existence of dark matter, after many different kinds…
A team of theoretical physicists thinks a fifth force could explain an anomaly spotted in a nuclear physics experiment. If true, it could have huge ramifications for particle physics and dark matter — but that’s a pretty big if.
Three potential detections from deep underground could be from dark matter particles. While still uncertain, the result suggests a particle mass in keeping with hints from several other experiments.
Dozens of galaxy clusters confirm that dark matter particles slip right past each other within messy cluster mergers.
Dark matter in the "Train Wreck" galaxy cluster (Abell 520) appears to behave in unusual ways. Now, new Hubble images are heating up the debate.
A new analysis showing a cloud of high-energy particles hovering around the center of the Milky Way could be the signature of dark matter and evidence of a “dark force”, but not everyone is convinced.
A new study of six young, star-forming galaxies suggests they have less dark matter than expected. But the results may say more about galaxy evolution than about the nature of dark matter.
Two projects are mapping the distribution of dark matter in the universe, probing scales both large and small.
Astronomers have discovered a spike of X-ray emission in galaxy clusters — “ordinary” interpretations don’t hold up, so some are turning to dark matter for answers.
Astronomers have found a set of new dwarf galaxy candidates near the Milky Way Galaxy, a discovery crucial to understanding dark matter.
An intensive study of dark matter’s distribution in the universe has verified predictions of where the invisible stuff that makes up the majority of cosmic matter resides.
An underground detector reports zero detections of weakly interacting massive particles (WIMPs), the top candidate for mysterious dark matter.
Astronomers analyzing a new sky survey have found that the distribution of dark matter in the modern universe is smoother than predicted from observations of a far younger universe.
Scientists using an instrument aboard the International Space Station have measured a signal that might come from dark matter — or might not.
A simple experiment has detected a signal from the first stars forming just 180 million years after the Big Bang. The observations have intriguing implications for the nature of dark matter.
The Antarctic observatory known as IceCube has ruled out the existence of a fourth type of neutrino particle — and one-time dark matter contender — known as the light sterile neutrino.
A combo of Hubble and Gaia data reveal the distribution of dark matter in a tiny galaxy by tracking the galaxy’s stars.
Three astrophysicists discuss preparations for three recently funded dark matter experiments, and the likelihood that one of them will strike gold.
Satellite dwarf galaxies orbiting the Milky Way should help scientists better grasp the universe's evolution while also homing in on dark matter's identity.
Our galaxy's center region is producing gamma rays, but astronomers are still debating whether pulsars or dark matter are the source. Three recent studies tackle the debate head-on.
Two recent experiments limit physicists’ favorite candidate for the elusive and invisible matter lurking in the universe.
