A sweet astronomy story, for a little break:

Earth & its Moon were forged from a violent collision. But Pluto and its giant moon, Charon, came together with a gentle kiss. A similarly soft process may have occurred all across the outer solar system.

A 饝惔饝惗饝悷饝惗 (hiti) is an ancient Newah urban water feature: a stepped, sunken courtyard with waterspouts and a central pool. These are fed through a remarkable network of pipes, reservoirs, and irrigation systems drawing water from mountain springs dozens of kilometres away. Every day, hundreds of people from the neighbourhood come to draw water, bathe, and exchange news. They are a unique and precious feature of Newa urban architecture through which neighbourhoods are created.
