The Dark Energy Spectroscopic Instrument (DESI) is mapping millions of celestial objects to better understand dark energy—the mysterious driver of our universe's accelerating expansion. Today, the ...

DESI's first dataset maps 18.7 million celestial objects, aiding dark energy, galaxy, and universe expansion studies.

The 3D cosmic map building DESI has provided more clues that dark energy is weakening over time, suggesting our best model of ...

If dark energy is not constant, the effects would be huge. Our current model of the universe, called the Lambda Cold Dark ...

Physicists may need to come up with a new theory for how the universe works, after a dark energy experiment has produced confounding results.

Our scientists have played a leading role in creating the largest-ever 3D map of the universe, using data from 15 million galaxies and quasars. The map was produced by the Dark Energy Spectroscopic ...

Mayall 4-meter Telescope at Kitt Peak National Observatory, continues to build the largest 3D map of the universe ever created. By the time DESI completes its five-year mission next year ...

The universe’s expansion is accelerating, not decelerating. Our understanding of how the universe works may need an update.

Voluminous clouds of cosmic dust permeate our galaxy, but only recently has software allowed detailed observations of the stuff at scale.

Dark energy is a dynamic entity, rather than a matter-of-fact constant in the universe’s rapid unfurling, a team of ...

The fate of the universe hinges on the balance between matter and dark energy: the fundamental ingredient that drives its ...
