Right now, on your computer screen, are approximately 10,000 galaxies.
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 yet, with all that junk, the Universe is more than 90 percent empty space.
All of that, in this tiny photo. A photo that took 400 orbits and 800 exposures to take.
And the kicker? The photo covers one thirteen-millionth of the entire night sky.
