The return of Comet Halley in 1986

. Rays, streamers and kinks can be seen in the ion tail of Comet Halley during its 1986 return to the inner solar system. The broad, fan-shaped dust tail can also be seen. The radio galaxy known as Centaurus A, or NGC 5128, can be seen in the bottom left corner. It is about ten trillion, or 1013, times further away from the Earth than the comet is.
