Normally, black holes rip stars apart in the centers of galaxies. A new discovery shows that some black holes lurk in the outskirts. Astronomers spotted a flare tens of thousands of light-years from the center of a large galaxy. A computer algorithm trained on similar events helped identify it. Soon

Years of observations with XMM-Newton, Swift, and VLA showed how the changing-look active galaxy 1ES 1927+654 underwent a dramatic transition from a wind regime to a jet. X-ray spectra revealed oxygen emission lines and a broad iron line, while ionized absorption faded. Synchronously, radio emission
