Black hole 'burping' after 'eating' star seen for 1st time

In a first, astronomers have directly imaged the formation and expansion of a jet of material ejected when the gravitational force of a supermassive black hole ripped apart a nearby star. The tidal disruption event occurred 150 million light-years from Earth where a black hole 20 million times more massive than the Sun shredded a star twice the Sun's mass.
