Fire rainbows are the rarest of all naturally occurring atmospheric phenomena. For a fire rainbow to occur, cirrus clouds must be 20,000 feet in the air with the precise amount of ice crystals, and the sun must hit the clouds at 58 degrees.

Pluto & Charon
By Mark Dorf, Digital Artist, New York
Charon is a moon of Pluto that is unlike others in our galaxy — instead of orbiting around Pluto, the moon Charon is gravitationally locked and the two spin on an axis. The facing surfaces of the galactic satellites also never shift away from one another: they are forever alone together staring at one another at the edge of our galaxy.
