Radio Astronomers Discover Compact Object with Ultra-Powerful Magnetic Field astronomy space science
telescope have discovered a spinning object that pulses every 18.18 minutes; they’ve localized the radio source to within our own Milky Way Galaxy and suggest that it could be an ultra-long-period magnetar.“This object was appearing and disappearing over a few hours during our observations,” said, an astronomer with the Curtin University node of the International Centre for Radio Astronomy Research.
“The MWA’s wide field of view and extreme sensitivity are perfect for surveying the entire sky and detecting the unexpected.”Slow transients — like supernovae — might appear over the course of a few days and disappear after a few months. “The mysterious object was incredibly bright and smaller than the Sun, emitting highly-polarized radio waves — suggesting the object had an extremely strong magnetic field.”“It’s a type of slowly spinning neutron star that has been predicted to exist theoretically,” she added.
