Two salt lagoons on the Mediterranean coast of south-eastern Spain sit side by side with strikingly different colors. The La Mata and Torrevieja lagoons have long been used for salt production. La Mata is less salty, while the Torrevieja lagoon is hypersaline, meaning its water is far saltier than seawater. Those differences in salinity shape the lagoons' colors, as satellite imagery from the Copernicus program captures. The contrast makes the area a striking example of how salt production and natural chemistry mix.

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.
