Where can I see the aurora borealis?

Why is aurora borealis so special?

Polar lights (aurora polaris) are a natural phenomenon that can be quite a sight! They are found in both the northern and southern hemispheres. When particles boosted in energy in the Earth’s upper atmosphere collide with oxygen and nitrogen atoms, they produce auroral light which is a sight to behold.

What is aurora borealis and why does it happen?

Aurora happen when the solar wind travels past the magnetic field and goes towards the Earth, eventually running into the atmosphere. The protons and electrons released from the solar wind hit the particles in the earth’s atmosphere thereby releasing energy. This causes the northern lights, also known as aurora borealis.

What causes aurora borealis?

Aurora is caused by the lines of force in the Earth’s magnetic field.
