ALMA researchers reported the discovery of oxygen in the most distant known galaxy. Geologists believe unusual structures in ...

Cosmic microwave background data support cosmology’s standard model but retain a mystery about the universe’s expansion rate.

University of Arizona researchers are among a group of scientists who hope to discover what happened immediately after the Big Bang, when the universe expanded in a fraction of a ...

Physics Professor Colin Hill and collaborators have released the clearest images to-date of the universe in its infancy.

An accidental discovery by a team of astronomers has upended existing theories about how galaxies formed in the early ...

And yet, here is JADES-GS-z13-1, defying our best models of the universe. “We really shouldn’t have found a galaxy like this, given our understanding of the way the universe has evolved ...

DESI's first dataset maps 18.7 million celestial objects, aiding dark energy, galaxy, and universe expansion studies.

DESI maps distant objects to study dark energy. The instrument is installed on the Nicholas U. Mayall 4-meter Telescope, shown here beneath star trails. (Credit: KPNO ...

The standard model of how the universe works involves the widely accepted theory that dark energy is a fundamental constant of nature that drives the accelerating expansion of the universe. But a new ...

That allows Staggs, who is also a Princeton University professor, and others to test existing mathematical models of the universe. "When we have better and better maps, we can do a better and ...
