Yesterday (2024-05-28)

Acraea terpsicore, commonly known as the tawny coster, is a species of butterfly in the Nymphalidae family, the brush-footed butterflies. It is found across eastern Asia from India and Sri Lanka to Singapore, Indonesia and the Maldives and, more recently, Australia. It is small, with a size of 53–64 millimetres (2.1–2.5 in), has leathery wings and is common in grassland and scrub habitats. Acraea terpsicore has a weak fluttery flight and is avoided by most insect predators. This A. terpsicore individual was photographed in Komodo National Park, Indonesia.

Today (2024-05-29)

Lake Estancia was a prehistoric body of water in the Estancia Valley, in the center of the U.S. state of New Mexico. Mostly fed by creek and groundwater from the Manzano Mountains, the lake had diverse fauna, including cutthroat trout. It appears to have formed when a river system broke up. It reached a maximum water level (highstand) presumably during the Illinoian glaciation and subsequently fluctuated between a desiccated basin and fuller stages. Wind-driven erosion has excavated depressions in the former lakebed that are in part filled with playas (dry lake beds). The lake was one of several pluvial lakes in southwestern North America that developed during the late Pleistocene. Their formation has been variously attributed to decreased temperatures during the ice age and increased precipitation; a shutdown of the thermohaline circulation and the Laurentide Ice Sheet altered atmospheric circulation patterns and increased precipitation in the region. The lake has yielded a good paleoclimatic record. This map shows the shoreline of Lake Estancia at three different periods: early Estancia (1,939 m / 6,362 ft above sea level), late Estancia (1,897 m / 6,224 ft), and "Lake Willard" (1,870 m / 6,135 ft). Present-day populated places, county boundaries and roads are overlaid on the map for identification.

Tomorrow (2024-05-30)

A peanut, also known as a groundnut, is the fruit of Arachis hypogaea, a plant in the family Fabaceae. The peanut is classed as a grain legume rather than as a botanical nut, although in culinary and colloquial use it is generally treated as one. Uses of peanuts include consumption as a snack and in various dishes, peanut butter, and – due to its high oil content – as a vegetable oil. Peanuts cause allergic reactions in some humans. Clockwise from top left, this photograph shows a peanut with its shell cracked open, a whole unshelled peanut, an unpeeled peanut seed, a halved peeled seed, and a whole peeled seed. This picture was focus-stacked from 31 separate images.
