Lesson 105 of science

The milky way, the galaxy we live in, is located in a spiral shaped galaxy. The arms and center of our galaxy contain billions of stars. Supernovas are exploding stars that release lots of deadly radiation that flows through multiple stars and planets. Both the center and arms of the galaxy contain very high levels of radiation. Almost all of the stars in our galaxy are located in areas that have too much radiation to support human life. Our solar system is located on the edge of the milky way about two-thirds out of the way of the radiation. In the area we are in we are least likely to suffer a collision of stars. Most of the largest stars are in the center or larger spiral arms. There are less stars near us so we have less radiation and a less of a chance of a possibility of a supernova. With the less radiation it is easier for us to see other stars at night.
