(PhysOrg.com) -- Some dramatic galaxies eject gigantic, collimated jets of ionized gas millions of light-years long, powered by the massive black holes at their centers. The ionized jets are detected at radio wavelengths, and sometimes in the optical, but most of these active galactic nuclei also produce X-rays in the vicinities of the nuclei.
