Observations of an object called Hebe, near the galaxy GN-z11, point to stars formed just 400 million years after the Big Bang. By detecting ionized helium and hydrogen without heavy elements, researchers confirm predictions that these primordial stars were massive, hot, and chemically pure, ranging from 10 to 100 times the Sun’s mass. Backed by two independent studies, the discovery offers a rare glimpse into how the first stars drove the chemical evolution of the cosmos. Thank you for listening to Bedtime Astronomy — your guide to the cosmos. New episodes on space exploration, NASA missions & the latest astronomy breakthroughs.
