Key Takeaways:
- The article identifies NGC 3982 as a face-on spiral galaxy, with observation credits to NASA/ESA/the Hubble Heritage Team.
- It posits that the force of gravity is responsible for the spherical morphology of certain celestial bodies, exemplified by the Sun.
- Furthermore, the combined effect of an object's spin and gravitational forces results in the formation of a rotating disk.
- This resultant rotating disk is characterized by a vertical thickness significantly smaller than its radial dimension.

The force of gravity makes some objects, such as the Sun, spherical. Spin plus gravity equals a rotating disk with a vertical thickness much less than its radius.
