The James Webb Space Telescope spotted bright points of light from an era just 100–300 million years after the Big Bang. At first they were taken for distant galaxies, but now a hypothesis suggests they might be lone fireworks — explosions of the very first stars.

400 million years after the Big Bang, the James Webb Space Telescope noticed a bright spot near the galaxy GN-z11 — like a distant lighthouse whose light pushed through the primordial darkness.

Immediately after the Big Bang, an idea championed by Georges Lemaître, the cosmos was a dark broth of hydrogen and helium. Then the first stars ignited — enormous, dazzlingly bright and hot, like sparks from a cosmic bonfire.
