The Milky Way Broke Its Arm

The video explores the Milky Way's structure and challenges in studying it from within. Recent discoveries reveal a new feature in the Sagittarius arm, suggesting the Galaxy is less smooth than previously thought. The video also examines the asteroid Phaeathon, which behaves like a comet due to sodium vaporization, contributing to the Geminid meteor shower. These findings enhance our understanding of galactic evolution and the blurred lines between asteroids and comets.
