Radio Signal from Early Universe May Reveal the Masses of the First Stars

A newly modelled 21-centimetre radio signal from hydrogen atoms just 100 million years after the Big Bang may reveal the mass of the universe’s first stars. Using REACH and the upcoming SKA telescopes, researchers aim to uncover how early starlight shaped cosmic evolution during the Cosmic Dawn, when the universe transitioned from darkness to light.
