NASA's Hubble Tracks a Roaming Magnetar of Unknown Origin

An artist’s impression of a magnetar, which is a special type of neutron star with an incredibly strong magnetic field. The neutron star at the center of the image is illustrated as a mottled blue-white sphere with a bright edge and streamers looping off it. Concentric blue lines wrap around the neutron star, like a cage, from upper right to lower left to symbolize the intense magnetic field the star possesses. The words "artist's concept" are at bottom right.

Summary

Highly magnetic neutron star is wandering our Milky Way galaxy.

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 object is the likeliest candidate in our Milky Way galaxy for a magnetar that was not born in a supernova explosion as initially predicted. Only about 30 magnetars have been discovered so far. A magnetar is a neutron star with a magnetic field about a trillion times more powerful than Earth’s magnetosphere. If a magnetar were only half the Moon’s distance, its intense field would wipe out the magnetic strip of every credit card on our planet. If a human got within 600 miles of a magnetar it would rip apart every atom inside the body.
