Earth's magnetosphere protects the planet's surface from charged particles of the solar wind. Without this protection, life as we know it would probably not exist on Earth. read more
The vacuum of space does not slow these ionized particles. However, where a planet has a magnetic field (such as the Earth),this protects the planet from the effects of the solar wind bydeflecting the charged particles. Thus the solar wind does notreach the surface of the Earth. read more
Earth’s magnetosphere is also vital in preventing our atmosphere from being pushed out into space by the pressure of the solar wind. For example, in 2008, Earth, Mars and the sun were aligned so that the same blast of solar wind hit the two planets, one after the other. read more
