In an active galaxy, matter falling toward the supermassive black hole powers high-energy emissions so intense that two classes of active galaxies, quasars and blazars, rank as the most luminous objects in the universe. Thick clouds of dust and gas near the central black hole screens out ultraviolet, optical and low-energy (or soft) X-ray light. Although there are many different types of active galaxy, astronomers explain the different observed properties based on how the galaxy angles into our line of sight. We view the brightest ones nearly face on, but as the angle increases, the surrounding ring of gas and dust absorbs increasing amounts of the black hole's emissions. || ",

Why, when most galaxies host giant black holes in their centers, do only about one percent of them emit vast amounts of energy? The new findings confirm that the black holes \"light up\" when galaxies collide — and may offer insight into the future behavior of the black hole in our own galaxy. The intense emission from galaxy centers, or nuclei, arises near a supermassive black hole containing between a million and a billion times the sun's mass. Giving off as much as 10 billion times the sun's energy, some of these active galactic nuclei (AGN) — a class that includes quasars and blazars — are the most luminous objects in the universe. || ",

            "description": "The Gamma-Ray Large Area Space Telescope (GLAST) will observe the sky in gamma-rays with energies between 10 million electron volts (MeV) to 300 billion electron volts (GeV) (a photon of visible light is roughly 2 electron volts). At these energies, the detectors will receive roughly 2 photons every second. At these energies, the objects visible will be active galaxies, quasars, pulsars, and gamma-ray bursts. This visualization is generated from one year of simulated photon event-lists using known sources. These event lists are used for testing the various data analysis software being developed for the project. Due to the extremely low event rate, it takes about one week of event accumulation to see structure in the sky. To generate the 600+ frames of this visualization, the event lists were box-car averaged for a duration of one week for each frame, and each frame shifted 50,000 seconds in time from the previous frame. The low angular resolution of gamma-ray detectors makes point sources appear spread out in the sky. In these maps, the color of each pixel represents the number of photons accumulated in that pixel (over an energy range of 10MeV-300GeV). Horizontally, across the center of the map, is the diffuse emission from the plane of our own Milky Way galaxy. The images are projected in galactic coordinates with a plate carrée projection so there is significant distortion with increasing latitude above the galactic disk. This emission in the galactic plane is created by pulsars and supernova remnants. Located away from this plane is emission from active galaxies and high-velocity pulsars. Occasionally, a bright spot appears which can be a gamma-ray burst or quasar in an active state. || ",
