Description:
NGC 5128, also known as Centaurus A, is a nearby galaxy about 12 million light-years away in the constellation Centaurus. It’s famous for its active supermassive black hole, which powers massive radio jets stretching over a million light-years into space.
These jets shoot out from the galaxy’s core at nearly the speed of light, emitting strong radio waves, X-rays, and gamma rays as they interact with surrounding gas. The jets are a sign of intense activity at the center, where matter falling into the black hole is partially ejected instead of being consumed.
NGC 5128’s unique structure—an elliptical galaxy with a dust lane from a past galactic merger—and its powerful jets make it one of the most studied active galaxies in the sky.
