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

General relativity has passed one of its most precise tests ever thanks to observations of the past 11 billion years of ...

The scientists, who are collaborating on something called the Dark Energy Spectroscopic Instrument (DESI) are studying the history of the universe's expansion out to 11 billion years in the past.

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

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 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 ...

Called the Dark Energy Spectroscopic Instrument, the collaboration released its first analysis of six 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 ...

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. ...
