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 ...

Space Dark energy bombshell sparks race to find a new model of the universe ‘Shocking’ results from a major astronomical study have raised doubts about the standard model of cosmology, forcing ...

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. Dark Energy Spectroscopic Instrument (DESI ...

Collaboration has obtained a high-precision cosmic-ray boron spectrum in the energy range of 10 GeV/n–8 TeV/n, and discovered ...

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.

If dark energy is weakening, as suggested by recent results, ... For w(z) greater than –1, the universe’s dark energy dilutes over time, consistent with DESI’s findings.

The Vera C. Rubin Observatory released a sneak peak of some of the images it is unveiling, the first set of space images from ...

There may be many more satellite galaxies in the Milky Way than have been observed, according to new Durham University ...

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

Even if DESI’s findings hold up, they still can’t say what dark energy is. But they can provide much stronger clues than cosmologists had before. The DESI-based model implies that dark energy ...

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.
