Existence of cosmic defects, called textures, proposed over a decade ago Scientists from the Institute of Physics of Cantabria (IFCA) and the University of Cambridge may have discovered an example of ...

(via Sabine Hossenfelder) In the Big Bang Theory, the cosmic microwave background — microwave-range radiation that floats through the entire universe at a steady 2.7 Kelvin — is evidence that a hot ...

What if the Big Bang wasn’t the beginning, but a middle chapter? A bold new theory now proposes that dark matter — the unseen force shaping galaxies and driving cosmic evolution — may have existed ...

A new radio signal detector could do away with the need for bulky helium cooling systems and allow us to listen in on the faintest signals in the universe. Share on Facebook (opens in a new window) ...

How did the universe begin? A compact NASA space telescope that uses less power than a refrigerator is poised to chip away at that very large question. Called SPHEREx, and set for launch on a SpaceX ...

The night sky deceives us. The universe should be ablaze with starlight, yet it isn’t. Discover how the finite speed of light, cosmic expansion, and invisible radiation from the Big Bang—the Cosmic ...

Nearly 400,000 years after the Big Bang, the primordial plasma of the infant universe cooled enough for the first atoms to coalesce, making space for the embedded radiation to soar free. That ...

Researchers suggest the universe's background radiation has been overestimated, potentially challenging the standard model of cosmology and our understanding of early galaxy formation. Space, time and ...
