Window of Possibility: Why the Hubble Ultra Deep Field Is The Most Incredible Photograph Ever Taken

We live on Earth. Earth is a clump of iron and magnesium and nickel, smeared with a thin layer of organic matter, and sleeved in vapor. It whirls along in a nearly circular orbit around a minor star we call the sun.
I know, the sun doesn't seem minor. It literally makes the world go round. And it's huge: The Earth is a chickpea and the sun is a beach ball. The sun comprises 99.9 percent of all the mass in the solar system. Which means Earth, Mars, Jupiter, Saturn, etc., all fit into that little 0.1 percent.
But, truly, our sun is exceedingly minor. Almost incomprehensibly minor.
We call our galaxy the Milky Way. There are at least 100 billion stars in it and our sun is one of those. A hundred billion is a big number, and humans are not evolved to appreciate numbers like that, but here's a try: If you had a bucket with a thousand marbles in it, you would need to procure 999,999 more of those buckets to get a billion marbles. Then you'd have to repeat the process a hundred times to get as many marbles as there are stars in our galaxy.
That's a lot of marbles.
