-A real picture of an active galaxy is shown above. Superimposing observations from three different instruments provides a comprehensive view of Centaurus A, revealing the powerful lobes and high-energy jets emanating from its central supermassive black hole. Visible light data captured by the Wide Field Imager at the La Silla Observatory shows the galaxy's stars and its characteristic dark dust lane in near "true color". Layered over this, X-ray data from the Chandra X-ray Observatory is shown in blue, capturing the high-energy jets blasting outward. Finally, radio-microwave data from the LABOCA instrument on the APEX telescope is superimposed in orange to map the extended lobes. Together, these three distinct wavelengths beautifully expose the complete, violent anatomy of this active galaxy.
