New hints from one of the most extensive surveys of the cosmos to date suggest that mysterious dark energy may be evolving in ways that could shift how astronomers understand the universe.

Paris: Dark energy makes up roughly 70 percent of the universe, yet we know nothing about it. Around 25 percent of the universe is the equally mysterious dark matter, leaving just five percent for ...

Recently, two major research groups—the Dark Energy Spectroscopic Instrument (DESI) and the Dark Energy Survey (DES)—have collected massive amounts of data by observing millions of galaxies.

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 ...

Dark energy makes up roughly 70% of the universe, yet we know nothing about it. Around 25% of the universe is the equally mysterious dark matter, leaving just 5% for everything that we can see and ...

Dark energy, the mysterious force thought to be driving the ever-faster expansion of the universe, appears to be changing over time, according to new observations released Wednesday. If dark ...

"There are more questions than answers at this point." Dark energy could have an accomplice that helps it slow the growth of large cosmic structures, such as vast superclusters made up of clusters ...

Dark matter is thought to pull galaxies together, while dark energy pushes them apart The European space telescope Euclid, a veritable ‘detective of the dark universe’ aided by AI and humans ...

The rest is made up of 25% dark matter and 70% dark energy. Dark matter is already a mysterious phenomenon, being made of presumably particles that don’t interact with light, but dark energy is ...
