James Webb Space Telescope discovers the secrets of cosmic ‘factories’ that filled the early universe with stardust

NeRD

Using the James Webb Space Telescope (JWST), astronomers have discovered the secrets of early galaxies that pumped the infant cosmos full of dust, which would become vital for the birth of new stars and the growth of galaxies. However, while the JWST is powerful enough to see many of these early galaxies, it is still limited when it comes to delving into them in great detail.
