Jets of relativistic plasma created by the Supermassive Black Hole at the center of 3C 348; a galaxy in the Hercules Cluster 1000 times more massive than the Milky Way. The jets are focused beams of particles accelerated to more than half of light speed by the magnetic fields around the Black Hole. The jets extend more than a million light years into intergalactic space. This image is a combination of visible light observations by the Hubble Space Telescope and radio observations by the VLA R
Astronomers have discovered the largest known structure in the universe, a clump of active galactic cores that stretch 4 billion light-years from end to end. The structure is a light quasar group (LQG), a collection of extremely luminous Galactic Nulcei powered by supermassive central black holes!
NGC 3627: Revealing Hidden Black Holes The spiral galaxy NGC 3627 is located about 30 million light years from Earth. This composite image includes X-ray data from NASA’s Chandra X-ray Observatory (blue), infrared data from the Spitzer Space Telescope (red), and optical data from the Hubble Space Telescope and the Very Large Telescope (yellow). The inset shows the central region, which contains a bright X-ray source that is likely powered by material falling onto a supermassive black hole.
