And you thought your planet was just sooooo special, didn’t you? Look, just because planet Earth exists in that amazing habitable zone where the sun’s rays are neither too hot and powerful nor too faint to preclude life – and just because an abundance of liquid water, oxygen and CO2 has led to stunning biodiversity and a vast range of climates – that doesn’t make us special. It makes us goddamned lucky, is what that’s all about. And besides, the deeper we look into space, the more we realize we might not be the only game in town.
