Faint radio signals from the early Universe, soon detectable by Moon missions, may reveal how dark matter shaped gas cooling and clumping in the cosmic Dark Ages. Ordinary matter, which makes up the ...

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 ...

Galaxies are far more than the sum of their stars. Long before stars even formed, dark matter clumped up and drew regular matter together with its gravity, providing the invisible scaffolding upon ...

Dark matter remains one of the most compelling enigmas in modern cosmology. Although it does not emit light, its gravitational influence is essential for the formation and evolution of cosmic ...

An international research collaboration has used advanced computer simulations to investigate how faint radio signals from the early universe, soon to be observed from missions on the far side of the ...

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 ...

Dark energy is responsible for the expansion of the Universe, but its true nature is still a subject of much debate. Computer simulations based on the latest astronomical data enable scientists to ...

No theory could explain the slight excess of far-ultraviolet light in the Milky Way until now.

Stars close to the centre of our galaxy may be nearly immortal because they gobble up dark matter for energy. More than two decades ago, astronomers noticed something odd about the stars near the ...

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 ...
