. NASAтАЩs Great Observatories have captured the bubble of debris that surrounds the last supernova seen in our galaxy. In this combined image, HubbleтАЩs visible light observations appear yellow, SpitzerтАЩs infrared observations appear red, and ChandraтАЩs X-ray observations appear blue and green (representing high-energy and low-energy X rays, respectively).

... A radio galaxy is a galaxy that emits an unusually big amount of energy at radio wavelengths. ... Inside of each galaxy with an active nucleus (radio galaxies are among them) there must be a system of a "central machine" responsible for the colossal amount of the emitted energy from radio to gamma ranges. ... Sometimes a radio source in an active galaxy may flare again if the needed conditions appear (a new portion of matter would fall into the furnace of the "central machine"). ...
