Black Hole Jet With 'Peculiar' Radio Signal

 From Space:

Astronomers have spotted mysterious changes in a jet of highly magnetic plasma blasted out by a small black hole that is gorging on gas and dust. The feature takes the form of periodic changes in the jet  occurring within a fraction of a second that have been detected by the Five-hundred-meter Aperture Spherical radio Telescope (FAST) in China. Astronomers know that the strange blinking object, called GRS 1915+105, consists of a regular star orbiting a stellar black hole, a black hole that was born after a massive star had died. As the star orbits the black hole, some of its material gets sucked into the cosmic monster, which fails to swallow all of the material and instead accelerates some of it into the jet that appears to squirt from its poles.
