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 ...

Brown dwarfs are too small to sustain the nuclear fusion that powers most stars, so they cool and fade over time. But if they ...

First, we picked a dark energy density between zero and 100,000 times the observed value. Depending on the amount, gravity ...

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 ...

Cosmologist Katie Mack breaks down what the latest findings about dark energy mean for our universe’s future. Either way, it won’t be happy.

New evidence suggests the universe might not behave as expected, raising questions about the costs of being wrong.

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 the wake of bombshell findings that suggest dark energy might be weakening as the universe expands, physicists are considering replacing the standard cosmological model of the universe with ...

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.

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 ...

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.
