The sun emits a stream of energetic electrons and protons called the solar wind. These particles frequently get caught up in the earth's magnetic field, traveling in spiral paths that take them toward the north or south magnetic poles. When they head northward and collide with atoms in the earth's upper atmosphere, those atoms emit light we know as the aurora borealis, or northern lights. These particles also interfere with radio reception. Why do they emit radio waves?
