À propos de cet audio
Dr. Hakeem Ali-Bocas Alexander guides us through the vast architecture of the Milky Way, from its supermassive black hole heart to its star-forming spiral arms.
•Discover the barred spiral structure of our galaxy, spanning 100,000 light-years across, with its rotating disk, central bulge, and graceful spiral arms teeming with stellar activity.
•Explore the galactic core where Sagittarius A*, a supermassive black hole, exerts tremendous gravitational influence over surrounding stars and interstellar material.
•Journey through the spiral arms where clouds of gas and dust collapse to form new stars, providing crucial insights into the life cycle of stars and planetary systems like our own.
•Learn about the Milky Way's eventual collision with the Andromeda Galaxy in 4.5 billion years and how this cosmic dance reveals the dynamic nature of galactic evolution.
