I began my life as a stellar nebula. I was a tiny piece of stellar dust floating around in the universe. 

A stellar nebula looks like colorful lumpy mash potatoes. 

In my stellar nebula, I began finding all of my 

stellar dust friends and I stuck to them, making a big cluster of stellar dust. I squeezed together with my friends to make a proton star. Then I ignited into a massive star.

A teaspoon of a massive star weighs as much as a crew ship full of people.   

This is where I will spend most of my life as a 

massive main sequence star.

As a massive sequence star, I had a LOT of mass! For food I ate hydrogen. I am 1,000 times more massive than the sun.

After a while I ran out of my food, hydrogen. So, I had to eat helium instead. Helium is kind of like fried chicken or hamburgers of the star world. The more helium I ate, the fatter and bigger I got! I expanded so much I turned into a super red giant.

I burn 1,000 times brighter than the sun. 

You would have a stomach ache all the time, and wouldn't be able to move because you would be so fat. It eats helium to get its energy.   

                          Red Super Giant!

Soon, I ate so much helium that I exploded into a super nova. Little pieces of me blasted all around me! My explosion was so big you could hear and see the super nova from light years away.
