Deep in the center of our galaxy, scientists believe a strange type of star may be quietly glowing—not from fusion like our ...

Dev says that if the incoming particle was dark matter and not a neutrino, it could explain this mystery. The shallow predicted path of the incoming particle meant that it had to travel through ...

Dark matter affects how stars move within galaxies, how galaxies build up over time, and how everything in the universe is held together—but no existing tool has directly detected it. While dark ...

Known for its large mass despite emitting very little light, Segue 1 is traditionally viewed as a prime candidate for studying dark matter-dominated galaxies. However, the unique investigation ...

Dark matter, which is thought to constitute the majority of all matter, does not reflect, absorb, or emit light. But it does have mass, which means it generates gravity and can cause gravitational ...

Dark Matter coverage from Scientific American, featuring news and articles about advances in the field.

But it only accounts for about 15% of matter in all of the known universe. The vast majority of matter is dark – invisible until it is detected only through its gravitational effects.

Observations and simulations combined, astronomers knew they needed to rethink how the universe worked, and slowly the idea of dark matter took hold. By the early 1980s, consensus emerged: Dark ...
