The sun's rays warm our bodies and tan our skin. Sometimes, however, the sun sends more than warmth and light to our planet. Sometimes it sends solar winds. Well, sometimes there are big explosions on the sun called solar flares.
Solar flares are bigger than any other explosions in our solar system.
They burst out of the surface of the sun near sunspots and sometimes they send hot gas flying toward our planet. Many times, nothing happens. That is because the Earth is protected by a magnetic force field called the magnetosphere. When a solar wind blows, it huffs and it puffs, but most of the winds can not blow through our magnetosphere. Even though we can not see our magnetosphere with our eyes, it is strong.
