Great job! You have managed to classify galaxies using the same data as professional astronomers! Not only can you classify galaxies by looking at their shapes, you know that the way stars and gas move inside the galaxies tells us a lot about them. But the best thing is that everything you saw here is just a small part of our universe. There are always new things to discover, and perhaps one day you can be a part of those new discoveries.
We hope you enjoyed this activity and that it has helped you get a little closer to the work of an astronomer. We invite you to continue your path in this branch of science with the activities available on the SDSS Voyages site because, as we said, there is always more to discover about our universe.
