25 Comments on A stellar history of modern astronomy | Emily Levesque

  1. 11:21 170 000 Light years away? I really thought there wouldn’t be anything there? Isn’t that too far to still be in the Milky Way yet too close to be in another galaxy?

    • Our galaxy, the Milky way, has two small satelite galaxies, the Large Magellanic Cloud and the Small Magellanic Cloud.
      It’s thought that the Milky Way is around 100k light years in diameter, and our Sun is a little more than half-way out from the center, orbiting it once every 225 million years.
      The center of our galaxy is an extremely large black hole – a so-called super-massive black hole.

    • @Peter Knutsen didn’t know about the satellite galaxies, thx! Only knew about the 100 000 lightyear diameter (which would make 170k well outside our “disk”)
