A new analysis of distant galaxies imaged by NASA's James Webb Space Telescope shows that they are extremely young and share some remarkable similarities to "green peas," a rare class of small galaxies in our cosmic backyard. "With detailed…

New data from the James Webb Space Telescope (JWST) have revealed that the structures of galaxies in the early universe were much more diverse and mature than previously known. Scientists compared images of hundreds of galaxies taken by…

In a new study, a team of astronomers led by Haojing Yan at the University of Missouriused data from NASA's James Webb Space Telescope (JWST) Early Release Observations and discovered 87 galaxies that could be the earliest known galaxies in…

New images from NASA's James Webb Space Telescope (JWST) reveal for the first time galaxies with stellar bars -- elongated features of stars stretching from the centers of galaxies into their outer disks -- at a time when the universe was a…

In giant clusters of hundreds or thousands of galaxies, innumerable stars wander among the galaxies like lost souls, emitting a ghostly haze of light. These stars are not gravitationally tied to any one galaxy in a cluster. The nagging…

For decades, the Hubble Space Telescope and ground-based telescopes have provided us with spectacular images of galaxies. This all changed when the James Webb Space Telescope (JWST) launched in December 2021 and successfully completed…
