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.

The effect was first tentatively reported in April last year, but the latest results — presented on 19 March by the Dark Energy Spectroscopic Instrument (DESI) collaboration at a meeting of the ...

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.

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.

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. ...

Findings from the Dark Energy Spectroscopic Instrument (DESI) suggest that dark energy could be evolving over time. If they're right, cosmology will need a new model.

NEW YORK (AP) — Distant, ancient galaxies are giving scientists more hints that a mysterious force called dark energy may not be what they thought. Astronomers know that the universe is being ...
