The 3D cosmic map building DESI has provided more clues that dark energy is weakening over time, suggesting our best model of cosmic evolution could be wrong.

Together, the data match dynamical dark energy better than the standard picture, by a statistical measure as large as 4.2 sigma, depending on which data are used, the researchers report in a paper ...

NASA's James Webb Space Telescope (JWST) has produced a new image of the Bullet Cluster, which is a titanic collision between ...

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 spring, a team of nearly 1,000 cosmologists announced that dark energy — the enigmatic agent propelling the universe to swell in size at an ever-increasing rate — might be slackening.The ...

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 ...

Physicists may need to come up with a new theory for how the universe works, after a dark energy experiment produced confounding results. An international team of scientists has released a "3D map ...

The largest-ever 3D map of the cosmos hints that the dark energy that’s fueling the universe’s expansion may be weakening. One community of theoretical physicists expected as much. On the morning of ...
