One of the most amazing sites to see are the Polar Auroras which occur between the Sun and the Earths magnetic fields Before scientific studies began which wasnt until the mid-1800s people watched the auroras but worried about the danger that they may possess While learning about the Auroras it is important to understand that there is a giant magnetic field surrounding the Earth The Earths core is made up of metals which acts like a magnet This creates a magnetic field known as the magnetosphere that extends deep into space Because of this field it affects nearby objects The Earths magnetic field varies in strength but the poles of the Earth are the strongest In empty space the Earths magnetic field does not exist Although the sun has a magnetic field too Atomic particles are always boiling off the Sun and moving at extremely high speeds The solar field and the boiling particles create the solar wind which pushes onto the Earths magnetic field changing its shape When the solar wind reaches the Earth from the Sun which takes 3 to 6 days it creates bright Auroras The intensity and brightness of the Auroras totally depends on the number of particles and how active the Suns wind is Hence the less active the Sun is the smaller the Auroras will be These particles from the solar wind flow into the equatorial regions of Earth and become trapped in the ring current Particles that are positively charged move westward while negatively charged particles drift eastward Some of these particles flow along the magnetic field into the polar regions in a process in which scientist still do not fully understand The lights at the poles are called Aurora Borealis Northern Lights and Aurora Australis Southern lights Another effect that derives from the solar wind and the Earths atmosphere is the color of the Auroras The different colors of light depend on which gas
