（单词翻译）

 But the sun's violent burst can harm us, its active nature is what allows us to live at all, because the sun also eject the solar wind, and energized¹ stream of particles that head out into space, and that we can see passing-off as it bounces off our atmosphere, the aurorae². Then the solar wind flies on, putting on the same show at the poles of Jupiter, and Satur, too. Until finally one hundred earths' distance away, it loses its momentum³ and forms a boundary with deep space, creating a protective bubbl that shields our solar system from dangerous galatic radiation and cosmic rays, the heliousphere. within it, life on the planet just a right distance away can thrive. We are beneficiary of the energy the sun generates as nuclear fusion⁴ fights back against gravity.
