M87 Jet – Knot Flaring (Annotated)

This annotated movie shows a zoom into the giant elliptical galaxy M87. Inside that galaxy is one of the most massive black holes discovered to date. Hubble astronomers are focusing their attention on a narrow jet of gas and radiation coming from that black hole. That jet seems to have a mysterious glowing knot in it – one that is brightening and fading over a period of several years.
