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...
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.
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.
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.
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.
Scientists using an instrument aboard the International Space Station have measured a signal that might come from dark matter — or might not.
Two recent experiments limit physicists’ favorite candidate for the elusive and invisible matter lurking in the universe.
