JWST Detects Oldest Supernova Ever Seen, Linked to GRB 250314A

Astronomers using the James Webb Space Telescope have detected the oldest supernova ever recorded, tied to gamma-ray burst GRB 250314A. Occurring when the universe was only 730 million years old, the explosion provides a rare glimpse into the first generations of stars and early galaxy growth, highlighting Webb’s unmatched ability to study the distant cosmos.

Chandra’s New X-Ray Mapping Exposes the Invisible Engines Powering Galaxy Clusters

NASA’s Chandra X-ray Observatory has released stunning colour-coded galaxy cluster images that reveal shock waves, cooling gas, and cavities carved by supermassive black holes. By separating X-ray light into different energy bands, astronomers can now visualise hidden cosmic processes that shape the universe’s largest structures and control how galaxies grow over ...
