The NASA image above is the recent Hubble Extreme Deep Field, a compilation of hundreds of Hubble images of a tiny, tiny slice of the night sky.
To get a feel for the size of the area of the sky covered by the image, go outside and hold a pencil at arms length. The area covered by the eraser is about the size of this image.
Highly educated scientists are paid good money to do this stuff, like count the number of galaxies, not stars, galaxies, in the image.
The number is about 5,500.
A galaxy might have a few stars (ten million) or many (our Milky Way is estimated to have 200 billion)...so...doing the math on a tiny sliver of the sky with 5,500 galaxies each with millions, billions of stars...multiply by the area of the entire sky...well...gives one a headache.
It is not a cliche to say that the whole business of the universe is mind boggling.
I'll have to classify it all under two scriptures:
In the beginning God created the heavens and the earth.
When I consider thy heavens, the work of thy fingers, the moon and the stars, which thou hast ordained;
What is man, that thou art mindful of him? and the son of man, that thou visitest him?
Sometimes we think too small...I think.
