For generations, humans have gazed at the stars and wondered about the ultimate fate of the universe. Will it expand forever ...

A recent study suggests the universe's fate may be a dramatic end, as decreasing dark energy could potentially lead to a 'big ...

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

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

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.

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 ...

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.

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.

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 ...

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 ...

The Dark Energy Spectroscopic Instrument is atop the National Science Foundation’s Nicholas U. Mayall 4-meter Telescope at Kitt Peak National Observatory in Tucson, Arizona.

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. ...
