You're looking at the first photos taken of the Small and Large #MagellanicClouds, which aren't clouds at all, but galaxies beyond our #MilkyWay!
Taken by HC Russell for his book Photographs of The Milky-Way, these were shot at the Sydney Observatory in the 1890s.

A quintessentially Earthly scene 🙌
Oxygen scatters sunlight making the sky blue; water reflects the sky; dust makes sunsets orange; after sunset our transparent atmosphere reveals the surrounding universe. Water, organic molecules and sunlight allow life to thrive.

'The simplest useful criterion is the lagtime, or difference between sunset and moonset. If it's greater than 47 mins (at the latitude of Sydney) the #CrescentMoon should be visible to the unaided eye after sunset and before the setting of the Moon.'
