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

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 ...

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 ...

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 ...

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 ...

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

Artist’s impression of a forming galaxy cluster in the early Universe: radio jets from active galaxies are embedded in a hot intracluster atmosphere (red), illustrating a large thermal reservoir of ...

The geometry of spacetime forms the very foundation of modern gravitational theory, where the elegant interplay between curvature and matter is described by Einstein’s field equations. In this ...
