381-life-cloud-comet-dixon – This astronomical landscape depicts a bright comet with a long, sweeping tail trailing across a deep purple and pink twilight sky on an early terrestrial world. In the foreground, primitive green biological mats thrive in a body of water, which perfectly mirrors the comet's reflection and the rugged, volcanic rock formations lining the coast. The scene visualizes theories of panspermia or the delivery of organic compounds to early Earth by cometary impacts. - painting by Don Dixon for Geo Magazine
