When I first went into Zooniverse, I looked around at a couple different programs, until I finally decided to take part of the Galaxy Zoo program. This program shows and helps us understand how galaxies form, and how to classify them according to their shapes. This program helped me classify 36 different galaxies.
Overall, this program taught me that galaxies are classified based upon their shape (smooth, features or disks, or star or artifact). After you classify what shape it is, you then have to classify the following: how round it is, if the disk is edge-on, the center bulges and how prominent they are, number of spiral arms and how tightly wound they are, if it has bars, if there is anything odd, if it has a mostly clumpy appearance and the arrangement of how many clumps there are, if one clump is brighter than the other and central to the galaxy, if the clumps are embedded with a larger object, and its symmetry.
