Called the Dark Energy Spectroscopic Instrument (DESI), the collaboration released its first analysis of 6 million galaxies and quasars last year and has now added more data, bringing the count to ...

Now, recent findings released March 19 from two of the largest cosmological surveys to date - the Dark Energy Spectroscopic Instrument (DESI) survey and the Dark Energy Survey (DES) - challenge ...

Astronomers have uncovered the most promising evidence yet for the existence of dark stars—giant cosmic objects powered by ...

Scientists have found that dark energy, the force thought to be accelerating the expansion of the universe, may be doing the same thing to local groups of galaxies. That bolsters Einstein's ...

Dark energy, a mysterious force that scientists believe is behind the accelerated expansion of the universe, is weakening — which could result in the universe over the course of billions of ...

Columnist and Physics How dark energy findings may inspire a new generation of physics nerds. The discovery of the cosmic acceleration problem truly inspired me as a teenage physics nerd.

In an analysis of a group of distant supernovas, astronomers have found hints that dark energy is distributed uniformly throughout space.

Dark energy is the name physicists have given to the mysterious thing driving the universe's accelerated expansion. It may be a force or a form of energy, and one piece of evidence suggests it is ...

The findings announced on Tuesday are part of a years-long study of the history of the cosmos focusing upon dark energy, an invisible and enigmatic force that is accelerating the ongoing expansion ...

Is dark energy dead? The new findings aren't definitive. Astronomers say they need more data to overturn a theory that seemed to fit together so well.

Recent findings from the DESI and DES cosmological surveys challenge the long-held assumption of a constant dark energy density, suggesting instead that it may vary over cosmic time.
