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

Six years of Dark Energy Survey observations combine four cosmological probes to refine measurements of cosmic expansion, dark energy behavior, and matter clustering across billions of years.

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 ...

A team of physicists have proposed a new cosmological model – dubbed the "black hole universe" – that suggests that our universe did not begin at the Big Bang. For a long time the universe was assumed ...

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 ...

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, ...

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 ...

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.
