Good morning class, I hope you're all ready to learn about the life cycle of High Mass stars!
My name is Professor Lucas. Today you will be very lucky; you will get to see the life of a High Mass star. Outside right now is an interstellar cloud of dust and gas called a nebula that will collapse due to gravity and form a star.
See, now the gas and dust of the nebula has collapsed together into a small star called a prostar. It's basically a baby star.
Look! That one looks kind of like Saturn!
Do you think any of them have life?
It's very possible.
Now the star is what we call a main sequence star. It's much larger than our Sun, but they are both on this stage. The star is at the center of it's own solar system, with planets all around it.
Now everyone hold on tight!
Now the star is what we call a Red Supergiant. It has eaten up all its hydrogen and is expanding. It is about 1,000 times as big as our sun now. As it expands outwards it burn up all its planets. This is how all planets eventually meet their fate.
