1. At the planetarium, I learned many things. The first thing is that there is a black hole in the center of each galaxy that holds them together. I also learned that there are many types of galaxies. Some types are Olyptical, Spiral, and Peculiar. A third thing I learned was that you can see many planets like Mars from Earth. One fourth thing was that you can see different constellations at diffent times/seasons. Last thing I learned is that galaxies can collied, but not harm eachother.
