Astronomers using data from NASA’s Hubble Space Telescope have observed what appears to be a clump of dark matter left behind from a wreck between massive clusters of galaxies. The result could ...

A new theory published in the APS physicsjournal seeks to explain the origin and proliferation of dark matter through the introduction of a simple concept: what if dark matter can turn regular matter ...

A simple explanation of dark matter and antimatter, how they differ, how scientists study them, and why both are important to understanding the universe.

Strange events seen at the very heart of the Milky Way could be smoking gun evidence of a new dark matter suspect. If that is the case, scientists may have been missing the subtle impact of dark ...

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, ...

Dec. 12 (UPI) --New analysis by astrophysicists at the Massachusetts Institute of Technology suggests dark matter could explain a mysterious source of gamma rays in the center of the Milky Way. Gamma ...

A mysterious glow at the center of the Milky Way has puzzled astronomers for more than a decade. New research offers an explanation that could also reshape what we know about dark matter. When you ...

When it comes to the largest things we can observe in the Universe -- galaxies, clusters of galaxies and even larger assemblies of structures -- all of the normal matter present, in all its forms, ...

Space is a strange place, and the variety of objects and phenomena in the Universe is always fertile ground for scientific investigation. Sometimes we find particles or energy signatures where we ...

The first evidence for dark matter were galaxies that behaved as if they had far more matter than could be accounted for by the mass of their stars. Since then, we've found many other indications that ...

In the 1930s, a Swiss astronomer named Fritz Zwicky noticed that galaxies in a distant cluster were orbiting one another much faster than they should have been given the amount of visible mass they ...
