This paper will talk about the Planetary Nebula. The name came from a man called William Herschel. He called the sphere shaped clouds a planetary nebula because it is round just like a planet is. The word Nebula comes from the latin word Nebulae or Nebulas which means cloud. This paper will also consist of different information about the stars and life “cycle” of the stars. A Planetary Nebula is formed when a star's outer layers are blown off and they expand into space which would soon form the Nebula. A Nebula is the shape of a bubble or a ring. The reason why a Planetary Nebula is so colorful is because of the remains of stars that are left behind whenever a the star's outer layers are blown off. Unlike the name of the Planetary Nebula …show more content…

It is the life stage that comes right after the stage called Red Giant. It is also right before the stage called white dwarf. The Planetary Nebula is the outer layer of a star that's lost when a Red Giant transforms into a white dwarf. A Planetary Nebula is basically a cloud of gas and dust that has formed in …show more content…

It is considered a nursery for stars because that is where the stars are. You might also ask what is a star? Well a star is very big exploding balls of gas, made up mostly of hydrogen and helium. Our sun is also one of the biggest stars. Nebulas are where the stars are born. A Nebula is a very important part of the life cycle of a star. Nebulas make very unique stars that we have in our galaxy. Without Nebulas we wouldn’t have as many stars as we have now and who knows if we would even have stars. This is why a Nebula is very important to the life cycle of a star. There are two different kind of nebulas, Planetary and Stellar. Most Nebulae are about a hundred of light years in diameter. Some objects that are stellar can be considered a Nebula but it will be four different kinds. There is DIffuse Nebulae, Emission Nebulae, and Reflection Nebulae. Diffuse Nebulae is that they have no boundaries and Emission and Reflection Nebulae are based on how they react with light. This is what my essay was about. At first you didn't know much about the Planetary nebula but now have you learned some facts. You learned what a PLanetary Nebula is and what it is made of. You also learned why the Planetary Nebula is important to the life cycle of a star. You also learned what stars are and what they’re made
