At just 25, Cecilia Payne-Gaposchkin applied quantum physics to a treasure trove of astronomical observations to show that stars are mostly hydrogen and helium.

Interstellar objects like 3I/ATLAS that have been captured in planet-forming disks around young stars could become the seeds of giant planets, bypassing a hurdle that theoretical models have ...

Stars form in the universe from massive clouds of gas. European Southern Observatory, CC BY-SA For decades, astronomers have wondered what the very first stars in the universe were like. These stars ...
