In December 2024, astronomers caught a rare superluminous supernova in action, and it did something unexpected. It kept pulsing. Scientists raced to explain what made this cosmic explosion so unusual. Was this our first ever glimpse at the birth of a magnetar - one of the most extreme objects in the universe?
