The Universe: Countless Wonders of the Milky Way (S2, E4) | Full Episode | History
HISTORY・2 minutes read
The birth and construction of the Milky Way galaxy, along with the presence of a supermassive black hole at its center, impact star formation and the galaxy's future collision with the Andromeda galaxy. Various telescopes and wavelengths aid astronomers in studying the galaxy's structure, star formation, and the impacts of black holes, providing insights into the universe's vast complexities.
Insights
- The Milky Way galaxy, home to our solar system, is a dynamic environment where stars are born and die, with a central bulge housing a supermassive black hole that cannot be directly seen due to light not escaping it.
- The Milky Way's collision with the Andromeda galaxy in the distant future, the slowing of star production due to gas depletion, and the formation of stars in the spiral arms all contribute to the ongoing evolution and transformation of our galaxy.
