Astronomers have long been puzzled by two strange phenomena at the heart of our galaxy. First, the gas in the central molecular zone (CMZ), a dense and chaotic region near the Milky Way's core, ...

A NASA telescope may have detected evidence of dark matter, enabling it to be “‘seen” for the first time. Since dark matter was conceptualized nearly 100 years ago by Swiss astronomer Fritz Zwicky, ...

Dark matter is one of nature's most confounding mysteries. It keeps particle physicists up at night and cosmologists glued to their supercomputer simulations. We know it's real because its mass ...

Dark matter may be invisible, but scientists are getting closer to understanding whether it follows the same rules as everything we can see. By comparing how galaxies move through cosmic gravity wells ...

The glowing red band represents high concentrations of gamma rays across the center of the Milky Way. NASA / DOE / Fermi LAT Collaboration Dark matter—an unseen substance thought to make up 27 percent ...
