Experiments suggest an unusual magnetic material could help harness energy from Earth’s rotation. But not everyone is ...

Using data from nearly 15 million galaxies and quasars, the Dark Energy Spectroscopic Instrument (DESI) has created the most detailed 3D map of the universe ever made. A new analysis combining DESI’s ...

Some of the most fascinating people that you meet at American Physical Society meetings are not actually physicists, and Bruce Rosenbaum is no exception. Based in Massachusetts, Rosenbaum is a maker ...

The Dark Energy Spectroscopic Instrument (DESI) is mapping millions of celestial objects to better understand dark energy—the ...

New results from the Dark Energy Spectroscopic Instrument (DESI) suggest that the unknown force accelerating the expansion of ...

The fate of the universe hinges on the balance between matter and dark energy: the fundamental ingredient that drives its accelerating expansion.

The largest-ever three-dimensional map of the cosmos, plotting out some 15 million celestial objects, could help reveal the ultimate fate of the universe. Astrophysicists know that the universe is ...

Physicists may need to come up with a new theory for how the universe works, after a dark energy experiment has produced confounding results.

The DESI experiment shocked cosmologists with a hint that dark energy varies over time. Now, with more data, the conclusions hold up.

"This has been a decade-long detective story, with each recorded meteorite fall providing a new clue," said one astronomer.
