Coober Pedy is a town in northern South Australia, about 846 km from Adelaide, known as the opal capital of the world because of the precious opals mined there. Its scorching summer heat led residents to build underground homes called dugouts, which stay at a steadier, cooler temperature than houses on the surface. The name is thought to derive from a Kokatha-Barngarla term meaning whitefellas' hole, but in 1975 the local Aboriginal people adopted the name Umoona, meaning long life, which is also their name for the mulga tree.

Israeli reports also say the cabinet directed the military to prepare for a possible new attack on Iran.

Angkor, near Siem Reap in northern Cambodia, was the capital of the Khmer Empire, which ruled much of mainland Southeast Asia between roughly the 9th and 15th centuries. At its height the city spread across about 3,000 square kilometres, making it the largest pre-industrial city on Earth by area. Its growth depended on water: huge reservoirs called barays, along with canals and embankments, stored monsoon rain and carried it to rice fields. That system let farmers harvest more than once a year and fed a very large population through the dry season. The temple complex of Angkor Wat, built in the early 12th century, is the best-known monument and still stands at the heart of the park.
