 One Of The Strange Mysteries Of Our Sky Now, you might be wondering how galaxies are made. Just, how did they appear in our universe? Well, I’m here to answer your questions. Galaxies are made up of stars, dust, and crumpled up pieces of rock from space. Now, there are three different types of galaxies. The first type is called resular galaxies. They don’t always have the same shape. In fact, no one can tell what shape they are because they are always different! They contain very young stars and lots of dust and rock. The second kind of galaxies are called spiral galaxies. As you might have guessed, are shaped like spirals. Our Milky Way is a spiral galaxies. They contain middle aged stars with a medium amount of dust and gas. The third type of galaxies are called Elipticed galaxies. They don’t always have the same shape, but they usually are in the shape of a circle or an oval. Now that you’ve learned the basics of galaxies, here are some facts for you that you can go home today and say to your parents, “Hey mom! Guess what I learned today!” and have her not know the answer! Or, quiz your older brother right before his science! Did you know that there is almost always a black hole in the middle of a galaxy? Our Milky Way has one, too. So don’t go walking into the Milky Way any time soon! Or, gravity is always pushing galaxies either away or closer to one another? (But they are usually getting pushed away.) Hope you learned about galaxies with me! Article posted March 26, 2012 at 11:59 AM • comment • Reads 251 • see all articles |
