A mysterious excess of far-ultraviolet light seen across the Milky Way could come from the annihilation of clumpy dark matter ...

Describing matter under extreme conditions, such as those found inside neutron stars, remains an unsolved problem. The ...

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 ...

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, ...

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 ...

Normal matter – which makes up everything we see and touch – isn’t the only type of matter present in the universe.

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 ...

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 ...

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 ...

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 ...

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, ...
