When the luminoscity of the outer planets was calculated, that of Jupiter and Saturn was very high, indicating that these planets are giving off a lot of energy, more energy in fact than they are receiving from the sun.

There are several ways in which astronomical objects produce energy from inside. The first is thermonuclear fusion. This method of energy production is reserved for stars. Another method is by way of radioactive material within the ground. This method is at work in most terrestrial bodies.

For the giant planets the method which seems to be at work is the mere fact that energy is given off from when a planetary body is in the process of shrinking together, or collapsing on itself.

The fact that Jupiter is still collapsing together indicates that the process of planet formation is still going on. This process is providing the heat from within which causes the unusual motions in the atmosphere.

The energy that Jupiter and Saturn make has been found be very high.

Have you ever thought that a planet could make energy within itself? If you think about it, the ground is not very cold at all (except in the winter). This means that the Earth makes enough energy for the ground to be sort of warm most of the time.

The energy that Jupiter and Saturn have is very strong, meaning that Jupiter and Saturn are very warm from within themselves.

There are several ways for a heavenly object to make energy from inside. The first is by fusion, the way the sun makes energy. Another way is with radioactive material deep within the ground, the way a planet makes energy.

For the giant planets, the way that works is the mere fact that energy is made when a planet is in the process of shrinking together.

The fact that Jupiter is still shrinking together shows that the process of forming is still going on.
