3 Things We Still Don’t Understand About the Milky Way

The video explores three major mysteries of the Milky Way: its spiral shape, the unusual movements of its stars, and the origins of high-velocity gas clouds. Scientists are investigating the role of filaments in star formation, the rippling waves of stars possibly caused by past collisions, and the origins of high-velocity clouds, which may be remnants of ancient galactic interactions or supernovae. These mysteries highlight the complexity and dynamic nature of our galaxy.

How might the Milky Way's interaction with other galaxies affect its structure and the movement of stars?

What are high-velocity clouds and what theories exist about their origins?
