The James Webb Space Telescope and the Chandra X-ray Observatory have captured the clearest image yet of a galaxy cluster in the making, seen when the universe was only one billion years old.

The image Hubble captured was of the Egg Nebula, in the constellation Cygnus, about 1,000 light-years away, according to NASA.

Recent observations suggest that 'runaway' black holes are tumbling through the cosmos. Building on decades of theory, the discovery adds a remarkable new chapter to the story of the universe.

Since the 1990s, astronomers have found a handful of other dwarf planets in the belt, such as Eris and Sedna, along with ...

JWST and ESA’s Ariel mission plan coordinated exoplanet observations starting in 2030, combining high-resolution targeting and large-scale surveys to expand atmospheric data collection.
