In this visualization, each dot represents a gas parcel with a mass approximately 1,000 times that of the Sun in the simulation of the cosmic Dark Ages. The left and right panels compare the cold and ...

Physicists have unveiled a new way to simulate a mysterious form of dark matter that can collide with itself but not with normal matter. This self-interacting dark matter may trigger a dramatic ...

New supercomputer simulations hint that dark energy might be dynamic, not constant, subtly reshaping the Universe’s structure. The findings align with recent DESI observations, offering the strongest ...

A cosmological simulation study by researchers from the Shanghai Astronomical Observatory of the Chinese Academy of Sciences has systematically revealed, for the first time, how the interaction ...

Giant worlds beyond the Solar System could be the probe we need to figure out how dark matter manifests in the Universe. According to a new study, one particular dark matter model could see the ...

This may be remembered as one of the more important physics images of this generation. Credit: Tomonori Totani, The University of Tokyo Physicists from Japan's University of Tokyo have published a new ...

A chance configuration of objects arrayed across deep space has just revealed the hiding place of a giant glob of dark matter. Configurations like these, known as Einstein crosses, typically consist ...

It’s one of the most memorable moments of my career – and not in a good way. I was giving a talk to a room packed full of eminent astrophysicists, but there had been a bit of a childcare crisis, so ...

A puzzling ultraviolet light seen across the Milky Way could come from the destruction of nuggets of dark matter, the mysterious stuff that makes up around a quarter of the matter and energy in the ...

Astronomers have uncovered evidence that the Milky Way is not drifting through space alone but is embedded in a vast, flat structure of dark matter stretching tens of millions of light-years. The ...

On a clear night, the Milky Way and the Andromeda galaxy look like close neighbors. In space, they really are. Andromeda is even heading your way at about 100 kilometers per second. Now astronomers at ...
