New images show a galaxy forming that is similar to what our Milky Way’s mass might have been at the same stage of development. Nasa’s James Webb Space Telescope has detected and “weighed ...

By reconstructing stellar orbits using real Milky Way stars with accurately determined parameters, the team quantified the galaxy's mass-weighted chemical abundances and age structure. This ...

The galaxy is estimated to have formed 100-400 million years before its evolutionary stage that was observed by Webb, the most capable space telescope ever deployed. "The Milky Way began forming ...
