It would appear that Spaceship Earth has one more Shield against assault from space that we were not aware of.
We’ve known for 60 years about the Van Allen Radiation belt. And the Ozone layer. These protective layers absord and deflect charged particles from the Solar Wind and the more intense form of Ultra Violet radiation (light).
Well they have discovered a previously unknown shield between the two Van Allen belts. As described in the ScienceDaily article what this one protects us from are dangerously energetic electrons. These electrons are looping around the Earth at speeds of 100,000 miles per second. But they don’t get into the atmosphere because of this ‘transient storage ring’.
Congrats to Dr. Baker of CU-Boulder for carrying on his professor’s area of interest. That was Van Allen himself.
