For a generation, cosmologists have worked with a simple story: the universe is not only expanding, it is expanding faster ...

"These results from the Dark Energy Survey shine new light on our understanding of the universe and its expansion." ...

The six-year Dark Energy Survey has released its full results, showing that two leading models of cosmology are equally valid ...

After a century of observations spanning the breadth of the cosmos and theoretical insights that push humanity's vision of the universe to its utmost limits, we can finally, confidently say that the ...

AUSTIN (KXAN) — A commonly held belief that the universe is rapidly expanding may be wrong. A new paper published this month suggests the universe’s expansion might be slowing down and it could mean ...

Scientists have known for decades that the universe is expanding, but research in the past few years has shaken up calculations on the speed of growth -- raising tricky questions about theories of the ...

(CNN) — The universe’s expansion might not be accelerating but slowing down, a new study suggests. If confirmed, the finding would upend decades of established astronomical assumptions and rewrite our ...

A new Utah Valley University study is providing new evidence in a debate astronomers across the world haven’t been able to agree on — how fast the universe is expanding. The findings may add more fuel ...

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.

The plot represents the new model with the x-axis and the y-axis showing the minimum sizes of collapsing and expanding regions that can impact cosmological measurements. The contours are independent ...

DESI making observations in the night sky. The Rochester group has been part of DESI since 2017, with members having played key roles in commissioning and operating ...
