Researchers propose learning more about dark matter by looking for its effects inside exoplanets.
Roughly 80 percent of the mass of the universe appears to be dark matter: an invisible material that seems to interact with ordinary matter only through gravity, without emitting light or energy. Scientists cannot detect dark matter directly and don't yet know what it's made of, but they track its influence based on the motions of stars and galaxies. The presence of dark matter is necessary to explain the universe's current structure.
A new study suggests that annihilating dark matter particles may explain the Milky Way center's mysterious glow.
Evidence of collisions between black holes and neutron stars suggests dark matter might consist of concentrations of primordial black holes.
Astronomers discovered a radio structure that looks like a gigantic jellyfish, though it only glows in certain wavelengths.
Theoretical physics is supposed to be about pure, crisp ideas. But physics is done by humans, and human society brings messiness to any endeavor.
Nearly a century after dark matter was first proposed to explain the motion of galaxy clusters, physicists still have no idea what it’s made of.
Scientists are finally figuring out how much dark matter — the almost imperceptible material said to tug on everything, yet emit no light — really weighs.
Astronomers may be getting closer to discovering as-yet hidden cosmic secrets, such as the nature of dark matter and the presence of widespread distortions in space-time.
What if there is more than one cosmological agent for dark energy? This mixture would have strange effects in our universe, making it potentially detectable with upcoming surveys.
The search for dark matter is at a crossroads. Now, physicists have a new way to tell what the invisible stuff is made of.
New theory suggests cosmic bubbles during the birth of our universe are responsible for creating dark matter.
A pair of astronomers is advocating a daring new research program: to turn our widening search for life beyond Earth into a hunt for dark matter.
Scientists have conducted a new cosmos-wide matter census, finding that the stuff makes up 31% of our universe.
Once again, scientists have realized that when it comes to dark matter, they are missing a piece or two of the puzzle.
The imaging sensors for the future Vera C. Rubin Observatory have taken their record-breaking first photos.
Right now, key measurements of the universe's expansion are contradicting each other. A lost form of dark matter could help them agree.
A key signal for a certain kind of dark matter failed to turn up in a search throughout the Milky Way. Now scientists are disagreeing about what that means.
