The Sun

The Sun is a star. Our Sun is about 4.5 billion years old. The Sun gives of light an energy that helps life thrive.

How The Sun Gives off Light

The Sun Fuses atoms together to create bursts of energy. These happen so often about every millisecond that it looks like it is always happening.

How can light leave The Sun?

When a neutron tries to push of of the sun it is blocked and pushed around, so it may take hundreds of millions of years for one neutron to escape. Even weirder about 100,000 escape every second. This is how the sun shines!
