Coronal mass ejections (CMEs), often associated with solar flares, are the most powerful magnetic phenomena occurring on the Sun. Now, astronomers using NASA’s Chandra X-ray Observatory have spotted a gigantic CME erupting from the active star HR 9024. This is the first time a CME has been seen in a star other than our Sun. The results, published in the journal Nature Astronomy, confirm that CMEs are produced in magnetically active stars and are...
