The youngest stars are found in the spiral arms of the galactic disk. The precession of the Earth's rotation axis is caused by the gravitational pulls of the Sun and the Moon on the Earth's equatorial bulge. It has about 1800 times more mass than its negatively-charged electron counterpart. In a chain process involving three or more reactions, the net result is four hydrogen nuclei are fused together to form a helium nucleus plus energy. The protostar is warm enough to produce a lot of infrared and some microwave radiation.
Microwave energy is produced by the surrounding cocoon cloud.
