Nebula ?

I wrote this post as a response to Esther Chiltons weekly prompt.

Edge
On the edge of the galaxy, in the streaming snow of stars, a snake like creature swims the dust lanes.
Pure energy, it feeds on supernova and quasars.
Many thousands of years old, it has started to glow. Corruscating colours flowing along it’s length.
What is this Edge creature? Totally alien, made of quantum fluctuations, entangled electrons. Perhaps when it ripens the galaxy will twist like a newly lit Catherine wheel on bonfire night.
