Want a closer look? These two galaxies are thought to have exi | EverythingScience

Want a closer look? These two galaxies are thought to have existed 350 & 450 million years after the big bang (left to right). Unlike our Milky Way, these first galaxies are small and compact, with spherical or disk shapes rather than grand spirals.

‍This discovery suggests that stars might have started forming earlier than expected, perhaps as soon as 100 million years after the big bang. Follow-up observations with Webb’s spectrographs will confirm the distances of these 2 galaxies & help us learn more.
