    This is the scariest part: "Ultraviolet radiation from the black hole eruption energized the Magellanic Stream’s hydrogen gas (by splitting apart the protons and electrons in the hydrogen atoms), causing it to generate its own specific type of radiation (when the protons and electrons recombined). The amount of H-alpha emissions, the distance the brightest radiating portions of the Stream is from the galactic core and the rate at which the Stream would have cooled over time “all fits together, it all adds up,” said Greg Madsen, of the University of Cambridge and co-investigator for the study."
