Each day a different image or photograph of our fascinating universe is featured, along with a brief explanation written by a professional astronomer. The thin jet of electrons and protons shoots out at nearly light-speed likely from the vicinity of a large black hole at the galaxy center. At the left of the above image in X-rays is the radio galaxy Pictor A , known as a radio galaxy for its strong radio emission . At the far end of the jet on the right a hot spot glows as the intense particle beam bores through a gas cloud in intergalactic space. The jet and hot spot of Pictor A had been seen previously in radio waves, but only recently has the orbiting Chandra X-ray Observatory confirmed its unusual power.
