Dark energy, the mysterious force that’s driving the accelerating expansion of the universe, may not actually exist, scientists say. Their research has brought into question one of the cornerstones of modern cosmology. In a new study, published Dec. 19, 2024 in the journal Monthly Notices of the Royal Astronomical Society, the researchers analyzed data from … Read more
More than 4,000 small earthquakes have been rattling the Greek islands around Santorini and near the underwater volcano Kolumbo.

In the process, it discovered something rather surprising. Not only were there more galaxies (and brighter ones, too!) than expected, but these galaxies had supermassive … Read more
New observations from the James Webb Space Telescope (JWST) have corroborated data from its predecessor, the Hubble Space Telescope, to determine something is missing from our recipe of the cosmos. The JWST conducted its largest survey yet of the accelerating expansion of the cosmos as scientists attempt to discover why the universe is expanding faster … Read more
