In this image of the central region of the elliptical galaxy NGC 3862, an extragalactic jet of material moving at nearly the speed of light can be seen at the three o’clock position. The jet of ejected plasma is powered by energy from a supermassive black hole at NGC 3862’s center. A sequence of Hubble images of knots (in red, green, and blue) shows them moving along the jet over a 20-year span of observing. Astronomers were surprised to discover that the central knot (green) caught up with and merged with the knot in front of it (blue). Image credit: NASA / ESA / E. Meyer, STScI.
