James Webb Space Telescope Spots the Universe’s First Stars
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.
