- Using machines that study electrons and ions in space, NASA recently discovered a man-made barrier around Earth.
- It could be a force field: The barriers might protect planet Earth from “extreme space weather” such as coronal mass ejections, according to Newsweek, though further study is necessary to prove that theory.
- Coronal mass ejections are gigantic gas bubbles with magnetic fields that are spit out by the solar corona — the outer layer of the sun’s atmosphere — usually after solar flares.
- They’re potentially dangerous because they can cause geomagnetic storms on Earth. Read more (5/18/17)
