It was getting noticeably warmer. The ice that formed millennia ago, right after the comet came close to the Sun the last time and hurled away by the gravity sling into the frozen depths of outer Solar System, started melting on the surface. Icy shards poking out of the surface here and there were losing their geometrical precision and trickled into dirty puddles full of minerals and organic molecules that came from dust and small rocks trapped in the ice. At the molecular level, among the typical bustling activity of Brownian particles was order arising from chaos. Ideal spheres were consuming simple molecules and weaving them together into long threads of complex ones. And the puddles began to glow with fluorescent pink light.
