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

Could the universe be spinning like a giant top? This idea, proposed by physicist Nikodem Poplawski, opens surprising perspectives concerning dark energy and the structure of ...

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.

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.

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

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 ...

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 ...

The Dark Energy Spectroscopic Instrument used millions of galaxies and quasars to build the largest 3D map of our universe to date. Combining their data with other experiments shows signs that the ...

Called the Dark Energy Spectroscopic Instrument, it uses a telescope southwest of Tucson, Arizona, to create a three-dimensional map of the universe over 11 billion years to see how galaxies have ...

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. ...
