Close-up look at a jet near a black hole in galaxy M87 (ground-based view)

This radio image of the galaxy M 87, taken with the Very Large Array (VLA) radio telescope in February 1989, shows giant bubble-like structures where radio emission is thought to be powered by the jets of subatomic particles coming from the the galaxy's central black hole .

The false colour corresponds to the intensity of the radio energy being emitted by the jet. M 87 is located 50 million light-years away in the constellation Virgo.
