The Universe & Chocolate

Do you like chocolate? How about Milky Ways? Enough with the chocolate talk, let’s talk galaxies. There are four different types of known galaxies in the world. Those galaxies are Spiral galaxies, Elliptical galaxies, Irregular galaxies, and Quasars. The reason there are four different types, is because they are classified by different characteristics. The Spiral galaxy is one that should be important to us humans, because we live in one. Spiral galaxies are thin and structured with four sweeping arms. They are so humongous that it takes two hundred and fifty years to rotate completely around. Did you know that 77% of observed galaxies? Well, the closest one to the Milky Way, our galaxy, is a bigger sisterly one named Andromeda. Scientists predict that the two galaxies will once collide and then won’t be known as a Spiral galaxy, but an Elliptical galaxy. Discovered by Edwin Hubble in 1936, was the first Elliptical galaxy. Elliptical galaxies are one million light years across in diameter and have more than three trillion stars. As all galaxies, they are held together by gravity. If Earth was in an Elliptical galaxy, it would always be bright outside. They contain a lot of older stars versus younger stars. M87, an Elliptical galaxy, is one of the largest galaxies recorded. An Interesting fact is that, scientist think that they are nearing the end of the evolution line for galaxies. There are black holes in the middle of the galaxies which have an enormous black hole in the center that consumes gas and dust. Elliptical galaxies are often named after their size. Elliptical galaxies range from circular to long, narrow, and cigar-shaped galaxies. Ellipse in Elliptical means a circle, hence why it’s spherical. But not all galaxies are spheres; in fact Irregular galaxies are named that because their shape isn’t a circular shape, but an irregular one. Irregular galaxies are created by a large explosion or as most people know it, the big bang theory. The
