Researchers using NASA's Hubble Space Telescope have discovered the magnetar called SGR 0501+4516 is traversing our galaxy from an unknown place of origin. Researchers say that this runaway magnetar is the likeliest candidate in our Milky Way galaxy for a magnetar that was not born in a supernova explosion as initially predicted. It is so strange it might even offer clues to the mechanism behind events known as fast radio bursts...But a decade-long study with Hubble cast doubt on the magnetar's birthplace. After initial observations with ground-based telescopes shortly after SGR 0501+4516's discovery, researchers used Hubble's exquisite sensitivity and steady...
