As long as we're on the subject, what wigs me out is that the darkness of space that we see at night is filled with sunlight. It is streaming away from us of course, but all the same, it is invisible.
Yup....At midnight sunlight is blasting past, lighting up the lunar surface like a massive flood light, with all surround space appearing nearly black, throwing off so much light, the tiny shadows formed by the moons of Jupiter, almost 800,000 kilometers away from the sun, can easily been seen from earth, moving across it’s surface. The intensity is mind bending.
