Most cosmologists believe that these stars were the first large, free-floating structures to illuminate our universe, and that black holes appeared later. But some have proposed that it went the other ...

Astronomers have been confounded by recent evidence that the universe expanded at different rates throughout its life. New findings risk turning the tension into a crisis, scientists say. When you ...

Do scientists need to re-examine the basic model of the universe? Using new measurements of cosmic distances, astronomers have refined their calculation of the Hubble Constant, a number that describes ...

Paul M. Sutter is an astrophysicist at SUNY Stony Brook and the Flatiron Institute, host of "Ask a Spaceman" and "Space Radio," and author of "How to Die in Space." Sutter contributed this article to ...

Physical cosmology, as a branch of astrophysics, is the study of the large-scale structure of the universe and is concerned with fundamental questions about its formation and evolution. Cosmology ...

Astronomers determined in 1929 that the universe is expanding. This was one of the most important findings in science. In 1998, two separate groups of astrophysicists discovered that the universe’s ...

Forbes contributors publish independent expert analyses and insights. The Universe is out there, waiting for you to discover it. If you add them all together, as philosopher Bjørn Ekeberg did in his ...

The cracks in cosmology were supposed to take a while to appear. But when the James Webb Space Telescope (JWST) opened its lens last spring, extremely distant yet very bright galaxies immediately ...

A panel of physicists and astronomers grapple with possible cracks in our modern creation myth, the standard model of cosmology. JWST’s image of spiral galaxy NGC 628, which is 32 million light-years ...

Thomas Kitching receives funding from the Royal Society, and the Science & Technology Facilities Council. Science is advancing rapidly. We are eradicating diseases, venturing further into space and ...

Modern cosmology is taking us on the most exciting voyage in human history. Far from diminishing our wonder at the Universe, this modern story of Genesis surpasses even our wildest speculations.

Discoveries on the grandest scale in the cosmos, as well as findings a bit closer to home, share this year’s Nobel Prize in Physics. Cosmologist James Peebles of Princeton University won half the ...
