      @neiltyson are rainbows an arch or are they a complete circle?

      Complete circles, at right angles to your personal field of view, and generally truncated by the ground. leaving just arcs.

          So basically an arc, that would've been a circle if the ground wasn't there...?

          Don't need to be in space; if rain particles are below your view, and the sun behind you, you can see one from an airplane.

          They were circles but the leprechauns sawed them in half so they would point to the pot of gold. #BeforeGoogleMaps

          Christianity's explanation is god saying sorry for drowning everyone. Think I prefer the cold, hard science.
