please consider that there's an atmosphere between you and anything else like the moon and Jupiter and other stars. This atmosphere does all sorts
of fun things to cause effects like blinky twinling, shimmering, halos, auras, different color effects, and so on. Atmospheric lensing can make
things look bigger than they did the night before, or even smaller.
High ice crystals can cause effects too, as well as dust and heat shimmer, and many other things.
