Astronomers think that it shows where a massive star exploded as a supernova whose light reached Earth 1,700 years ago. The image combines optical data from the PanSTARRS telescopes in Hawaii (background stars in red, green, and blue), radio from the MeerKAT telescope in South Africa (large red cloud) and X-rays from NASA's Chandra X-ray Observatory and ESA’s XMM-Newton (shown in blue). The large cloud is a star forming region called Sagittarius C, which is approximately 50 light-years in ext...
