Using the Hubble Space Telescope, astronomers have, for the first time ever, mapped the plasma"burps" of a feeding supermassive black hole-powered quasar that dwells relatively close to Earth.
Artist's impression of a tidal disruption event, which occurs when a star passes too close to a supermassive black hole and is ripped apart, creating an accretion disk.Matter in the accretion disk is gradually fed to the central supermassive black hole, but if there is one thing scientists know about black holes, it is that they areNot all the matter in accretion disks is destined to fall into the black hole; some charged particles are channeled to its poles by powerful magnetic fields.
Using Hubble, Juráňová and colleagues discovered the properties of four different outflows of plasma from around I Zwicky 1. They found them to be moving at speeds between 134,000 mph , 200 times the speed of sound, and a staggering 6.5 million mph , which is around 8,500 times the speed of sound and around 1% of the speed of light..
