An international team of astronomers has used the James Webb Space Telescope (JWST) to observe a luminous dusty star-forming galaxy known as GN20. Results of the observational campaign, published April 26 on the arXiv preprint ...
An international team of space scientists has found evidence suggesting that planets could have formed during the so-called "cosmic noon." In their study, reported in the journal Nature Astronomy, the group used data from ...
Using the James Webb Space Telescope (JWST) and the Hubble Space Telescope (HST), astronomers from the University of Padua, Italy, and elsewhere have observed a metal-poor globular cluster known as Messier 92. The observations ...
The James Webb Space Telescope (JWST) appears to be finding multiple galaxies that grew too massive too soon after the Big Bang, if the standard model of cosmology is to be believed.
