More often than not, anything “quantum” makes you think of stuff on the tiniest of scales. But in reality, quantum phenomena govern everything—including cosmic giants scattered across the universe. And, as proof, astronomers may have just confirmed an old quantum prediction by studying an ultra-magnetic star.

In a recent paper published in Nature, astronomers describe their observations of the star 1E 1547.0-5408. This star happens to be a magnetar—an isolated neutron star with extremely powerful magnetic fields and X-ray emissions. According to the study, 1E 1547.0-5408’s magnetic field—over a trillion times stronger than Earth’s—appears to…
