NASA's Chandra X-ray Observatory and ground-based optical telescopes have located the supernova SN 2006gy in 2006.
The top panel of the image is an artist's impression of a supernova.
The bottom left panel is an optical observation and the bottom right panel is an X-ray observation. In these two panels, the supernova is the bright spot on top-right of the image. The nucleus of the galaxy where the supernova happened is the bottom spot.
