Every couple of years I'm reminded of the scale of the universe and I'm just as shocked every time.

You're only reminded of the scale the universe is not

Especially on realization that this 100k stars is only 0.0001% of the stars in our galaxy. It would take one million of these visualizations to represent the Milky Way.

  And the Milky Way galaxy is one of trillions.

    And that is only the observable universe

  I was surprised to learn recently that we can only see 5,000 stars from Earth with the naked eye.

    Is that even in the best conditions i.e. a dark site?

    Depends on your definition of "star." You can see the Andromeda galaxy with your naked eye (as well as the galactic center.)

      True, but IIUC, that's the only object you can see in the sky that is not a part of our galaxy.

        The Magellanic clouds are also visible to the naked eye.

      But you don’t see individual stars. When I have been out in the middle of nowhere and looked at the Andromeda galaxy, it just looks like a smudge. You need a telescope to really realize it is made up of many individual stars.

I found this video pretty mind-blowing in presenting the scale of the universe, especially through time: https://www.youtube.com/watch?v=uD4izuDMUQA https://www.youtube.com/watch?v=uD4izuDMUQA
