Crescent Neptune and Triton

Gliding silently through the outer Solar System, the Voyager 2 spacecraft camera captured Neptune and Triton together in crescent phase. The elegant picture of the gas giant planet and its cloudy moon was taken from behind just after closest approach in 1989. It could not have been taken from Earth because Neptune never shows a crescent phase to sunward Earth. The unusual vantage point also robs Neptune of its familiar blue hue, as sunlight seen from here is scattered forward, and so is reddened like the setting Sun. Neptune is smaller but more massive than Uranus, has several dark rings, and emits more light than it receives from the Sun. via NASA https://ift.tt/3y3gFaP

Wikipedia article of the day is Oryzomys dimidiatus. Check it out: Article-Link Summary: Oryzomys dimidiatus, also known as the Nicaraguan oryzomys, Thomas’s rice rat, or the Nicaraguan rice rat, is a rodent in the genus Oryzomys of the family Cricetidae. It is known from only three specimens, all collected in southeastern Nicaragua (range pictured) since 1904. Placed in Nectomys upon its discovery, it was later classified in its own subgenus of Oryzomys and finally recognized as closely related to other species now placed in Oryzomys, including the marsh rice rat and Oryzomys couesi, which occurs in the same region. With a head and body length of 118 to 128 mm (4.6 to 5.0 in), O. dimidiatus is a medium-sized rice rat. The upperparts are gray-brown and the underparts are grayish, not buffy as in O. couesi. The tail is only slightly darker above than below. All three specimens were caught near water and the species may be semiaquatic, spending some time in the water. There is currently not enough data to make a proper assessment of its conservation status. (This article is part of a featured topic: Oryzomys.)
