James Webb Space Telescope catches monster black hole napping after ‘overeating’ in the early universe

Napping after overfeeding on food is a dilemma many of us will be fortunate to face on Christmas Day. New research has shown that, billions of years ago, some early black holes also had to nap after overindulging.

Webb Sees a Supercluster of Galaxies Coming Together

As a species, we’ve come to the awareness that we’re a minuscule part of a vast Universe defined by galaxy superclusters and the large-scale structure of the Universe. Driven by a healthy intellectual curiosity, we’re examining our surroundings and facing the question posed by Nature: how did everything get this way? We only have incremental … Read more

‘Our understanding of the universe may be incomplete’: James Webb Space Telescope data suggests we need a ‘new cosmic feature’ to explain it all

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
