There are approximately 10,000 galaxies in this picture.
Each of those galaxies contains anywhere from ten million to one trillion stars.
The average star is roughly a million times the size of Earth.
And the kicker? The photo covers one thirteen-millionth of the entire night sky.
That’s small beans.
Since we can only observe stellar bodies that have had some effect on us (usually bombarding us with light), there is an outer limit to what we can see of the universe. What about the rest?
Well, according to some math we have no interest in going into, the size of the “actual” universe is so large that if the universe we just described (the impossibly, mind-bogglingly large one) were the size of a quarter, the actual universe would be the size of the Earth. Daaaaaaaamn.
