Jets of plasma fly away from the supermassive black hole in galaxy Hercules A. This image is a composite of visible light and radio data, combined from the Hubble and the Very Large Array.
The jets are composed of plasma, magnetic fields, and subatomic particles; they are travelling near the speed of light, and are 1.5 million light-years in length, dwarfing the galaxy at their centre.
NASA has a high-resolution version of this image available.
