VLA (Very Large Array) image of an interacting twin-jet radio galaxy. The two black dots (at the bottom centre) are each associated with one of the twin nuclei of a distant galaxy. The jets appear to interact and wrap around one another.

Very Large Array (VLA), National Radio Astronomy Observatory, Socorro, N.M. The VLA is a group of 27 bowl-shaped radio antennas. Each antenna is 25 metres (82 feet) across. When used together, they make one very powerful radio telescope.
