Evidence for a black hole at the core of a galaxy. False-color visible light image of the core of galaxy NGC 4261 made by the Hubble Space Telescope (HST). The 'donut' shape is thought to be a region of hot gas with a 300 light year wide inner disc of cooler gas and dust. At the center is a very bright object, possibly the hot accretion disc of ablack hole. There is also a feint V-shaped region coming from the core which correlates well with the 'jets' from the galaxy seen at radio wavelengths. Such jets also support the idea of a black hole at the core. NGC 4261 is about 45 million light years from Earth.
