Active Galaxy NGC 1275
Active galaxy NGC 1275, the central, dominant member of the large and relatively nearby Perseus Cluster of Galaxies, is a mysterious object. Wild-looking at visible wavelengths, the active galaxy is a prodigious source of x-rays and radio emission as it accretes matter from entire galaxies. This Hubble Space Telescope image highlights the resulting galactic debris and filaments of glowing gas, some up to 20,000 light-years long, that are held together by magnetic fields.
