Our Earth is one of the planets rotating around the sun but a little known fact is that the sun has protected our solar system through its internal spewing of a solar wind outward to form an invisible bubble called the heliosphere.  The sun is a gigantic fire hose spewing all kinds of particles in all directions.  At the point which the wind slows down to a stop is called the “termination shock”.   Where the stuff from the sun balances with the stuff from outside our galaxy is called the heliopause, just beyond the outer limits of our solar system.  Problem is this.  Over time, the wind jetting outward from the sun has coled a bit decreased in pressure and density.  This is sort of like blowing up a balloon but you can no longer push air into the balloon and it collapses a bit.  More bad stuff is getting in, past the shield.  So this bubble protects us from what?  Cosmic rays coming at us from all those other stars and black holes.  But wait, Earth seem to have a second protective barrier, Earth’s magnetic field. Wait again, some scientists think that more cosmic rays entering our atmosphere, due to the heliosphere break down, might make for more clouds and climate change.  Is it global warming created by man that is responsible for the North Pole ice fields to receed or the sun going through a cycle or unending diminishing of solar wind leading that allows cosmic rays to penetrate deeper into our skys?  Scientists have for the past 50 years been measuring and trying to understand this rather complicated process.  You might want to be aware of this development and look out for further research findings in the future in your news papers, magazines and scientific web sites.
