3 Ways the Milky Way Will Change During Your Lifetime

The video explores the dynamic nature of the Milky Way, highlighting its growth and star formation over a human lifetime. It discusses the expansion of spiral galaxies, the birth of new stars on galactic edges, and the fluctuating rates of star formation. The video also covers the occurrence of supernovas and the potential for future stellar explosions, emphasizing the ongoing changes in our galaxy.
