Some stars in our galaxy pulse like musical instruments, and scientists have found a way to listen in. These rhythmic starquakes, like vibrations in a string or drum, reveal vital clues about a star’s age, composition, and life cycle.
By studying these “melodies” in a star cluster called M67—whose stars are like solar siblings—researchers uncovered a strange pause in stellar evolution called the “plateau.” This discovery helps pinpoint stellar ages with remarkable precision, bringing us closer to understanding how stars, and ultimately our galaxy, have evolved.
