Be humbled

The Milky Way stretches over 100,000 light-years across. Our solar system lies on the edge of the galaxy. The colored area shows the portion of the galaxy that has been mapped out by the European Space Agency’s Gaia observatory

Gaia has recorded billions of objects, but that represents a tiny fraction of the massive galaxy in which we reside. This final illustration shows the area mapped out by Gaia.

Prior to Gaia's launch, about 1000 stars had been mapped to 1% precision, by the time its mission is complete more than 1 billion stars will have been mapped with the same precision.

Still, it is such a minute portion of the galaxy, and our galaxy is only one of more than 2 trillion galaxies in the universe.

Our galaxy itself contains a hundred billion stars.

It's a hundred thousand light years side to side.

It bulges in the middle sixteen thousand light years thick,
But out by us it's just three thousand light years wide.

We're thirty thousand light years from galactic central point.
We go 'round every two hundred million years.

And our galaxy is only one of millions of billions
In this amazing and expanding universe!

Was that image shot by a Voyager or the Tesla in space?

I’ll wait for Steve G.’s photo because if you right-click on it you get a pic where you can zoom in to see your house.

So I suppose this means they wont miss us or even notice when we're gone?

What blows me away about all these universe numbers is the deceptive idea of "one light-year." As if it's just one, just a tiny itsy bitsy thing. When in fact just one is bigger than anything imaginable. It's 6 trillion miles. That's more than 10,000 times the distance between earth and sun. And that's just one of light-year. Then I try to imagine just 2 light-years. Impossible. Then 3, then 10, then 100,000 light-years.

It's amazing any human is able to get anything done and not just stay stunned and overwhelmed by the sheer magnitude of it all.
