More than 100 million years ago, the giant elliptical galaxy NGC 1316 (center) began snacking on its small northern neighbor. Gas stripped from the smaller galaxy feeds a black hole at NGC 1316's center and helps power a bipolar jet of high-energy particles. This flow is essentially undetectable until it crashes into tenuous gas 500,000 light-years from the galaxy, where it produces radio emission (orange) in two large lobes, each 600,000 light-years across.
