The Superior Mirage
We don't hear or know as much about the superior mirage, so many think it is a rare occurrence. However, one form is so common that most of us do not recognize it as a mirage. The superior mirage can make objects appear to be floating in the air or cause objects actually located below the horizon to appear above it.

Twinkle, Twinkle: September Skies and Starlight
The lower atmosphere, where we stand to view the stars, is mottled with pockets of varying density. When the local air density changes rapidly with time, the light ray's path also alters rapidly. This slight but perceptible refraction bends the path one way, one moment, slightly different the next. This constant, but random shifting results in the star's image jiving and jiggling, fading in and out, and even changing colours before our eyes. This stellar dancing is what we call "twinkling."
