Asked in TelescopesRadio
Does the image from a radio telescope come from the same image produced by a light telescope?

Someone may need to correct me on this The image would generally look similar if the object gives off Radio waves. For example, a recent image was taken of the same Galaxy, one in Infra-red, one in visable light and one in Xray. On the Infra-Red and Visable light they look identicle, except for the colour it appears to be. Whearas the X-ray image shows only the center of the Galaxy, which tells us that the outer stars eiter give off none or a very small amount of X-ray.
