"This signifies a major development in astronomy and physics." Scientists may have "seen" dark matter for the first time, thanks to NASA's Fermi gamma-ray space telescope. If so, this would mark the ...

In the early 1930s, Swiss astronomer Fritz Zwicky observed galaxies in space moving faster than their mass should allow, prompting him to infer the presence of some invisible scaffolding—dark ...

Physicists using near-absolute-zero detectors have reached unprecedented sensitivity in the hunt for light dark matter. A groundbreaking scientific project known as QROCODILE, led by the University of ...

An unexplained glow that appears to emanate throughout the Milky Way’s outer regions could be our first hint of what dark matter is made of, but astronomers say it is too early to know for sure. Dark ...
