Gas and DustPossible Rewrite: Hubble Observes Trail of Gas and Dust Possibly Created by Runaway Black Hole

A supermassive black hole, weighing as much as 20 million Suns, has been discovered by NASA’s Hubble Space Telescope. The black hole is travelling so fast that if it were in our solar system, it could travel from Earth to the Moon in just 14 minutes. It has left behind a 200,000-light-year-long “contrail” of newborn stars, which is twice the diameter of our Milky Way galaxy. The trail is likely the result of a rare game of galactic billiards among three massive black holes. The black hole is plowing into gas in front of it to trigger new star formation along a narrow corridor. The trail must have lots of new stars, given that it is almost half as bright as the host galaxy it is linked to.
