A few great facts to know:
Our Sun is a medium sized, yellow dwarf star
If you wanted to fill the Sun with Earths, you would need about 1.3 million
The Sun's core is approximately 15 million degrees Celsius
Energy from the core takes about 170 000 years to reach the surface of the Sun
From the surface, heat and light energy takes only 8 min to reach Earth
The surface of the Sun is about 5 500 degrees Celsius
The Sun is made up of mostly hydrogen and a smaller amount of helium.
Hydrogen particles collide to form helium atoms, a process called nuclear fusion. This is how the Sun generates its power!

Why? Meet our Magnetic Field!
Why? Meet our Magnetic Field!
The Earth's magnetic field absorbs this radiation and concentrates it towards the poles.
Lucky for us, this results in...
The Aurora Borealis (for us Northern folks), and
The Aurora Australis (for the Southern folks)
