Constellations

Constellations are a wonderfully silly idea but I love them. The idea of seeing patterns in the stars - space is 3D and the stars we link together are just stars that are in the same direction as viewed from Earth. They may be vastly different distances along that common direction. But the seeing of patterns is a way that humans make sense of the world. And it helps us to find our way round the sky. These boards are in the cable car station for Mount Teide on Tenerife. The night sky is supposed to be very good up there!
