Jupiter is five times distant from the Earth yet has an atmospheric temperature little different from that of our planet. The source of the non-solar energy has been a mystery – now they think they might have cracked it. The paper, in the July issue of Nature, to too early to be influenced by the current space mission to Jupiter. Perhaps the shelf life of this new theory will be quite short.

This, it is claimed, is due to a massive black hole which is swallowing surrounding material. In the process strong magnetic radiation is emitted as well as jets of particles. Polarimetric observations have taken place (published in the Astrophysical Journal of July 2016). Polarimetry observes the intensity and and orientation of magnetic waves. Cygnus A is also one of the most powerful radio sources in the sky.
