This extended jet of cosmic materials, traveling near light speed, emerged from a distant galaxy. The flow is almost 2 million light-years long, at least 20 times larger than the Milky Way. Astronomers published their findings in the Astrophysical Journal Letters.
By the standards of space-based astronomy, NASA’s new NuSTAR (Nuclear Spectroscopic Telescope Array) telescope that will be launched later this month has a modest budget of $165 million. However, it and XMM-Newton will try to probe the insides of the supermassive black holes hidden inside of galaxies.
