APOD 1.8 Draconid Meteors Over Spain

Draconid Meteors over Spain

As far as the aesthetics this image is nice, but not really noteworthy as far as rising above the other week's posts. What is interesting is the interactive portion where the constellations are connected and labelled for you when you scroll over the image with the mouse. The unusually productive amount of meteors that streamed from the constellation Draco, the dragon, produced this image. They were caused by pebble-sized chunks from the debris of the comet 21P/Giacobini-Zinner and occur in October every year. The interactive part, being the  most interesting to me, is helpful when I'm trying to reference the constellations from a map and locate them in the sky. I like it because the image overlay puts the map in the sky for you, but doesn't have to connect the dots unless you choose to. It doesn't force either image into your mind to obscure the ability of locating the constellations in the night sky.
