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

The six-year results from the Dark Energy Survey highlight unresolved tensions in standard cosmological theory ...

The six-year Dark Energy Survey has released its full results, showing that two leading models of cosmology are equally valid — but both fail to explain one key observation.

Astronomers have confirmed the earliest barred spiral galaxy in the universe, a Milky-Way-like structure that existed just 2 ...

JWST has revealed a strange early universe filled with ultra-bright “blue monster” galaxies, mysterious “little red dots,” ...

James Webb has spotted mysterious little red dots in the early universe that may actually be hidden black holes, challenging long-held ideas about how galaxies and cosmic giants formed.

The Universe may not have started with the Big Bang, but instead “bounced” out of a massive black hole formed within a larger “parent” universe, according to a new scientific paper. Professor Enrique ...

Wormholes are often imagined as tunnels through space or time—shortcuts across the universe. But this image rests on a misunderstanding of work by physicists Albert Einstein and Nathan Rosen.

At 3.3 billion light-years across, the ring may challenge the “cosmological principle” that the universe looks uniform at sufficiently large scales.

The fate of the cosmos may be a bit different than previously expected. For years, scientists have talked about how the universe is always expanding — constantly moving outward, never stopping.

The end of the universe has always felt like a distant abstraction. But new calculations suggest that our original timeline might have been wildly optimistic. According to a team of Dutch scientists, ...
