Did you know that the Earth's magnetic field protects us from the Sun?

The magnetic field of the Earth plays a very important role in our lives, it protects us from the solar winds. These are currents of particles charged of energy emanated from the sun which emit radiation.
The magnetic fields of Earth extend from the core to the surface of the planet, an area known as the magnetosphere. This "sphere" around us is composed of invisible lines originated at the two poles (as if it were a magnet). The magnetosphere deflects the dangerous ultraviolet rays of the sun, keeping us safe from any risk.

When such solar mass collides with our protective sphere, solar radiation, charged of particles, move along the magnetosphere creating a beautiful and amazing light show. This phenomenon is known as the aurora Borealis.
Auroras are created when the electrically charged particles from the sun collides with gas atoms in the magnetosphere making these emit colored lights.

If we placed an imaginary magnet inside the Earth in the north-south direction and solar wind magnetic field that collided against, what we would see would be many uniform lines of magnetic field but instead, the solar winds push the magnetosphere and deform it, getting an elongated comet-shaped structure with a long tail in the opposite direction of the sun.

The northern lights usually occur at night in the polar regions, but can also occur in other areas of the world for short periods of time. When produced in the southern hemisphere is known as Aurora Australis while in the northern hemisphere is known as Aurora Borealis.
