The Plasma Shield That Protects Mankind
- Year Discovered: 2018
- Location: Billions Of Miles From Our System’s Center
While this might be one of the freakiest things discovered by NASA, it is also one of the most crucial. In 2018, NASA’s twin Voyager probes began moving out of our solar system and into interstellar space. As they did this, NASA scientists were in shock about what they came across. They found what astronomers call a “Heliopause.” It was once only theoretical, but it was assumed something was present to stop solar wind before it collided with more powerful cosmic rays.
The Voyager probes originally saw the possible heliopause years prior but got to study them once they got closer. Billions of miles from our solar system’s center is a plasma shield, that deflects or dilutes the worst incoming radiation from the rest of the universe. It somehow deflects 70% of all cosmic rays before they enter our system. Some have come to call it the “shield that guards the realms of man.” The fact that something is present to stop cosmic rays from hitting us is incredible in our book.
