La estructura más grande conocida en el universo, un grupo de núcleos activos de galaxias que se extienden a 4 mil millones de años-luz de extremo a extremo. La estructura es un grupo quasar luz (LQG), una colección de muy luminosa Galáctica Nulcei alimentados por agujeros negros supermasivos centrales.

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.

These images by NASA's Hubble Space Telescope show off two dramatically different face-on views of the spiral galaxy M51, dubbed the Whirlpool Galaxy.  The image at left, taken in visible light, highlights the attributes of a typical spiral galaxy, including graceful, curving arms, pink star-forming regions, and brilliant blue strands of star clusters. In the image at right, most of the starlight has been removed, revealing the Whirlpool's skeletal dust structure, as seen in near-infrared…
