What we saw in the DESI experiments, and now strengthened by our South Pole Telescope observations, is that dark energy is ...

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. This hints that our best ...

If dark energy is in fact weakening, it would likely mean that science's understanding of how the universe works will need to be rewritten. The new findings come from the Dark Energy Spectroscopic ...

Dark energy is weakening and the universe could (eventually) collapse, study says The Dark Energy Spectroscopic Instrument (DESI) is studying dark energy and the accelerated expansion of the universe.

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

The first year of data from the 5,000 robotic eyes of DESI shows Einstein's theory of general relativity is the right recipe for gravity despite the challenges of dark energy and dark matter.

The latest Dark Energy Spectroscopic Instrument results fall short of the discovery threshold but strengthen evidence for dynamical dark energy. Last year, we reported on an exciting hint of new ...

As the Vera C. Rubin Observatory surveys the night sky, astrophysicists expect to unlock the secrets of dark matter, dark ...

Using the Dark Energy Spectroscopic Instrument, or DESI, scientists have assembled the largest three-dimensional map of the universe to date. Earth is at the center in this animation.

Last year, we reported on an exciting hint of new physics in the first data analysis results from the Dark Energy Spectroscopic Instrument (DESI)—namely that the dark energy, rather than being ...

The result comes from three years’ worth of data gathered by the Dark Energy Spectroscopic Instrument (DESI) in Arizona. By combining this data with other measurements, such as maps of the ...

An artistic celebration of the Dark Energy Spectroscopic Instrument (DESI) year-one data, showing a slice of the larger 3D map that DESI is constructing during its five-year survey. ...
