Weekly Blog Post - "Stars and the Moon" (4|16|18 - 4|22|18)

Summary: During this week, I learned... nothing really. I already knew the phases of the moon and I knew the life cycle of a star. So... I'm just going to review what I already know: a star starts out as a cloud of dust and gas. It uses a process called nuclear fusion to help it stay bright for hundreds of years. It is noted that smaller stars tend to live longer than bigger stars because bigger stars burn themselves up too soon (literally). When it comes down to its last bit of energy, it becomes a red giant. Then it becomes a planetary nebula, which is when the outer layers are shed away. Then it becomes a white dwarf, and if it uses all its fuel, it could become a black hole. Stars that have giant explosions are called supernovas. 

SP1: Asking questions and defining problems. I asked scientific questions such as, "How does dark matter interact with stars?" and "Will Andromeda eat up the Milky Way?" (Andromeda is a bordering galaxy that gets 188 miles closer to us every second.) and "What will happen to our moon once the Sun becomes a red giant?" (which should happen in approximately 5 billion years.)
