By a stroke of luck, a team led by Dutch Ph.D. student Martijn Oei has discovered a radio galaxy of at least 16 million light-years long. The pair of plasma plumes is the largest structure made by a galaxy known thus far. The finding disproves some long-kept hypotheses about the growth of radio galaxies.

A supermassive black hole lurks in the center of many galaxies, which slows down the birth of new stars and therefore strongly influences the lifecycle of the galaxy as a...
