The James Webb telescope keeps finding early galaxies that look brighter, bigger and more mature than astronomers expected, forcing researchers to rethink how quickly the first galaxies formed stars and assembled after the Big Bang.

The James Webb Space Telescope has confirmed MoM-z14, the most distant spectroscopically confirmed galaxy yet, whose light left it about 280 million years after the Big Bang. It is one of a growing population of early galaxies that are brighter and more numerous than the models built before Webb predicted. That population is forcing a [...] The post The James Webb telescope keeps finding early galaxies that look brighter, bigger and more mature than astronomers expected, forcing researchers to r
