A vast magnetic bubble formed by solar wind deflects interstellar radiation

The heliosphere is a giant teardrop-shaped protective bubble in space inflated by the continuous stream of charged particles known as solar wind. Extending past Neptune and Pluto to more than 120 Astronomical Units, this magnetic bubble deflects roughly 70 percent of high-energy galactic cosmic rays.
