Our Galaxy: Everything We Know About the Milky Way

Embark on an awe‑inspiring tour of the Milky Way Galaxy — the barred spiral galaxy we call home. Discover how its disk spans 100 000 light‑years, while the central bulge holds ten billion old stars. Learn how our Local Armfits among four main spiral arms and why the galactic disk warps and wobbles. We’ll explore the supermassive black hole Sagittarius A*, the mysterious dark‑matter halo that makes up 90% of our galaxy’s mass, and the recently discovered Fermi bubbles. You’ll also hear about the Local Bubble cavity carved by ancient supernovae, the Milky Way’s place in the Local Group of over 50 galaxies, and the upcoming cosmic dance with Andromeda. With vivid analogies and the latest research, this documentary reveals our galaxy’s dynamic past, present, and future — and hints at the prospects for life among its hundreds of billions of planets.
