Gaze upon your universe, Earthling.
Now, here's where it gets interesting. This image captures 10,000 galaxies, and reaches back 13 billion years to a time approximately 400 to 800 million years after the Big Bang.
And here's where it gets mind-blowing. The image covers a tiny patch of sky which, before HUDF, appeared to be basically empty, and which equals roughly one thirteen-millionth of the total area of the sky. One thirteen-millionth of the total area of the sky!
The known universe is 78 billion light years across, it's expanding at an ever-increasing rate, which at its farthest reaches can exceed the speed of light, and it's chock full of a myriad of galaxies and an unknowable number of stars.
Think about that the next time you tie a #22 emerger on a 7X tippet.
