Ancient Galaxies Reveal Hidden Stellar Mass | Science News

Astronomers using the James Webb Space Telescope have uncovered a shocking secret: some of the earliest galaxies were three to four times more massive than previously thought, thanks to a hidden population of tiny, faint stars. By studying nine ancient galaxies that stopped forming stars billions of years ago, scientists revealed that bright, giant stars were just the tip of the iceberg—masking vast numbers of smaller stars that inflated the galaxies’ true size. This discovery upends current models of early galaxy formation and hints that planets may have been far more common in the cosmos’ infancy. Researchers are now racing to peer even deeper into time’s dawn, aiming to unravel how the universe’s first structures took shape.
