The deepening mystery around the JWST's early galaxies

When the JWST came to life and began observations, one of its first jobs was to gaze back in time at the early universe. The Assembly of Galaxies is one of the space telescope's four main science themes, and when it observed the universe's first galaxies, it uncovered a mystery. Some of them appear to have supermassive black holes (SMBH) in their centers that are fueling active galactic nuclei (AGN). However, they're not emitting X-rays, which is

The James Webb Telescope has discovered Zhulong, a massive and fully formed spiral galaxy where only primordial chaos was expected. Located in a universe with just a billion years old, it exhibits a complexity and mass that scientists believed impossible.

Scientists Discover the Milky Way’s Twin Born Just 1 Billion Years After the Big Bang

The discovery of Zhúlóng, an ultramassive spiral galaxy observed as it appeared just 12.8 billion years ago, challenges existing beliefs about how quickly galaxies like our Milky Way could form after the Big Bang. Using data collected by the James Webb Space Telescope (JWST) during its PANORAMIC survey, astronomers identified Zhúlóng as a grand-design spiral galaxy with well-defined structure. This level of organization so early in the universe’…
