Below is the Hubble Ultra Deep Field image, the most massive photo ever taken.
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, 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 most amazing part? The photo covers one thirteen-millionth of the entire night sky.
