A new analysis of astronomical data suggests unknown physics is at work assisting dark energy in acting almost as ...

The new findings come from the Dark Energy Spectroscopic Instrument (DESI), which sits on a telescope at the Kitt Peak ...

Not everything we knew about the universe is wrong. But not not everything. The Dark Energy Spectroscopic Instrument (DESI) ...

New data involving millions of galaxies and luminous galactic cores is providing fresh evidence that the enigmatic and ...

And now scientists are getting a little closer to understanding how it behaves. The big question is whether this dark energy ...

If dark energy continues to weaken, the accelerating expansion of the universe could slow — and possibly reverse. In that ...

The universe has been expanding ever since the Big Bang almost 14 billion years ago, and astronomers believe a kind of invisible force called dark energy is making it accelerate faster.

Using data from nearly 15 million galaxies and quasars, the Dark Energy Spectroscopic Instrument (DESI) has created the most detailed 3D map of the universe ever made. A new analysis combining DESI’s ...

The Dark Energy Spectroscopic Instrument (DESI) is studying dark energy and the accelerated expansion of the universe.

Dark energy is a mystery so daunting that it stretches and strains our most robust theories. The universe is expanding, driven by the unknown force that we've named Dark Energy. Dark Energy is ...

Here’s how it works. New results from the Dark Energy Spectroscopic Instrument (DESI) suggest that the unknown force accelerating the expansion of the universe isn't what we believed it to be.
