Summary

DescriptionCygnus A optical.jpg	English: Optical image of Cygnus A: This galaxy, at a distance of some 700 million light years, contains a giant bubble filled with hot, X-ray emitting gas detected by Chandra (blue). Radio data from the NSF's Very Large Array (red) reveal "hot spots" about 300,000 light years out from the center of the galaxy where powerful jets emanating from the galaxy's supermassive black hole end. Visible light data (yellow) from both Hubble and the DSS complete this view.

Image title	This montage features images of five different objects, ranging from a distant galaxy to a relatively close supernova remnant. Each image contains X-rays from Chandra along with data from other telescopes that detect different types of light. These images were released to commemorate the start of the International Year of Light 2015, a year-long celebration declared by the United Nations. These images illustrate how astronomers use different types of light together to get a more complete view of objects in space.
