    The giant elliptical galaxy, M87, has a supermassive black hole in its center. A long jet extends outward from the core of the galaxy, and huge radio lobes reach into space. New X-ray and radio data from the Chandra X-Ray Observatory and the Very Large Array Radio Observatory show that eruptions from the core of M87 have long-range effects. The hot eruptions stop cool gas from falling toward M87?s center to form new stars, and even affect surrounding galaxies.
