New results from the Dark Energy Spectroscopic Instrument (DESI) suggest that the unknown force accelerating the expansion of ...

A new map of cosmic expansion suggests that dark energy evolves over time, hinting that the universe doesn’t work the way we ...

"We report the discovery of one of the most distant galaxies known to date," astrophysicist Joris Witstok told Newsweek.

Dark energy may have a completely unknown aspect of physics acting as an accomplice in its efforts to defy gravity, ...

Euclid has opened a new window to the cosmos with its first deep sky data release, revealing millions of galaxies, ...

And it’s breathtaking: Galaxies of all shapes and sizes seem to be swimming about in a dark cosmic ocean, one peppered with strange circlets of starlight and erupting supermassive black holes.

New data further challenge the best scientific theory of the history and the structure of the universe. But a separate recent ...

Dark energy is the placeholder name scientists have given to the unknown force causing the universe to expand faster and ...

Last year, we reported on an exciting hint of new physics in the first data analysis results from the Dark Energy ...

Dark energy, in the form of a cosmological constant (Λ), has been seen as responsible for the accelerating expansion of space, holding a steady energy density.

Measurements of the faint afterglow of the Big Bang (known as the cosmic microwave background) are also important. They do not directly measure dark energy or how it evolves, but they provide ...
