Then: a crew returns to Earth after 241 days in orbit; new modelling suggests the galaxy’s most common planet may hide oceans of molten rock beneath clouds of vaporised rock; and astronomers pull a whole new layer of physics out of the first black hole ever photographed. We close with a both-hemispheres skywatch — the Southern Delta Aquariids, Comet 10P/Tempel, the Garnet Star, and how to hunt Pluto itself.
