Observations of the thermal energy in a baby galaxy cluster 12.4 billion light years away suggest much more energetic early cluster growth than current theories assume ...

An international team of astronomers led by Canadian researchers has found something the universe wasn't supposed to have: a galaxy cluster blazing with hot gas just 1.4 billion years after the Big ...

Add Yahoo as a preferred source to see more of our stories on Google. DESI has made the largest 3D map of our universe. The Earth is at the central vertex, and every ...

Our best models of the cosmos don't add up — but that could change if the universe is actually made of a viscous 'fluid,' a ...

It's hard to get a sense of the scale of the universe from our little corner of it, but scientists realized decades back that the universe is expanding. This naturally led to questions about the ...

The shape of the universe is not something we often think about.

Light from distant galaxies reveals important information about the nature of the universe and allows scientists to develop high-precision models of the history, evolution and structure of the cosmos.

An expanding universe complicates this picture just a little bit, because the universe absolutely refuses to be straightforward. Objects are still emitting light, and that light takes time to travel ...

Reproducible scientific software demonstrates that the CMB does not uniquely fix H₀, resolving the Hubble tension without conflicting with Planck data This is professional-grade scientific software, ...

Scientists from the University of Sheffield suggest that dark matter and neutrinos may interact, challenging existing ...

Supermassive black hole heating Current models suggest the massive reservoirs of gas that form the intracluster medium are collected, and then heated, by gravitational interactions as an immature, ...
