Planet Saturn Surrounded by Colorful Stripes
The planet Saturn has the most extensive and spectacular ring complex of any planet in the Solar System. Consisting essentially of a mixture of ice, dust and rocky material, they can reach a few hundred thousand kilometers in diameter, but do not exceed 1.5 km in thickness. Captured from Cumeada Observatory, headquarters of the Dark Sky® Alqueva Reserve, on 16th July 2021, at 01h58 UTC, just a few days before reaching the opposition. The image reveals nice and colorful stripes around the planet’s atmosphere, as seen in different hues. The gold and yellowish bands seen in Saturn’s atmosphere, are the result of superfast winds in the upper atmosphere, which can reach up to 1,800 km/h, around the equator. Being made up mostly of hydrogen and helium, the Ringed Planet is the least dense of all the planets, and is the only one less dense than water. If there were a bathtub big enough to hold it, Saturn would float in it.
PT: O planeta Saturno possui o complexo de anéis mais extenso e espetacular de qualquer planeta do Sistema Solar. Consistindo essencialmente de uma mistura de gelo, poeira e material rochoso, podem atingir algumas centenas de milhares de quilómetros de diâmetro, mas não ultrapassam 1,5 km de espessura. Captada no Observatório da Cumeada, sede oficial do Dark Sky® Alqueva, no dia 16 de Julho de 2021, à 01h58 UTC, poucos dias antes de atingir a oposição. A imagem revela assim uma atmosfera rica e colorida, com várias faixas de diferentes tonalidade ao redor do planeta. As faixas douradas e amareladas vistas na atmosfera de Saturno, são o resultado de ventos super rápidos na alta atmosfera, que podem chegar a 1.800 km/h, ao redor do equador. Sendo composto principalmente de hidrogénio e hélio, este Planeta anelado é o menos denso de todos os planetas, e é o único menos denso que a própria água. Se houvesse uma banheira grande o suficiente para contê-lo, Saturno flutuaria nela.

Like Flying over Plato Crater and Vallis Alpes Lunar Valley
Like if we were making an orbital flight over the moon, the image captured on March 23, 2021 from Dark Sky® Alqueva Observatory, in Cumeada village, Portugal, on a very steady night, shows in close-up a high-resolution sharp view of Plato and Vallis Alpes. Located on the northeastern shore of the Mare Imbrium, at the western extremity of the Montes Alpes mountain range. Plato is a lava-filled lunar impact crater with an age of around 3.84 billion years, featuring a 100,7km in diameter has an irregular rim with 2-km-tall jagged peaks that project prominent shadows across the crater floor when the Sun is at a low angle. Sections of the inner wall display signs of past slumping, most notably a large triangular slide along the western side. The rim of Plato is circular, but from the Earth it appears oval due to foreshortening. The flat floor of Plato has a relatively low albedo, making it appear dark in comparison to the surrounding rugged terrain. The floor is free of significant impact craters and lacks a central peak. However, there are a few small craterlets scattered across the floor. East of the crater, among the Montes Alpes, are several rilles collectively named the Rimae Plato. Near the lower left corner, is located Vallis Alpes, an incredible lunar valley featuring that bisects the Montes Alpes range. It extends 166 km from the Mare Imbrium basin. The valley is narrow at both ends and widens to a maximum width of about 10 km along the middle stretch. The valley floor is a flat, lava-flooded surface that is bisected by a slender, broken, cleft-like rille. The sides of the valley rise from the floor to the surrounding highland terrain, a blocky, irregular surface.
PT: Como se estivéssemos em pleno voo orbital sobre a lua, a imagem captada em 23 de Março de 2021 a partir do Observatório da Cumeada, no Dark Sky® Alqueva, Portugal, numa noite com a atmosfera muito estável, mostra uma visão nítida e em alta resolução da cratera Plato e Vallis Alpes. Localizada na costa nordeste do Mare Imbrium, na extremidade oeste da cordilheira dos Montes Alpes. Plato (Platão) é uma cratera de impacto lunar cheia de lava com uma idade de cerca de 3,84 mil milhões de anos, apresentando um diâmetro de 100,7 km e uma extremidadee irregular com picos recortados de 2 km de altura que projetam sombras proeminentes no chão da cratera quando o Sol está um ângulo baixo. Secções da parede interna mostram sinais de queda, no passado, principalmente uma grande marca triangular ao longo do lado oeste. O limbo de Plato é circular, mas visto da Terra parece oval devido ao efeito de compressão da perspectiva. O piso plano de Plato tem um albedo relativamente baixo, fazendo com que pareça escuro em comparação com o terreno acidentado circundante. O chão está livre de crateras de impacto significativas e não possui um pico central. No entanto, existem algumas pequenas crateras espalhadas pela superfície. A Este da cratera, entre os Montes Alpes, existem vários canais chamados coletivamente de Rimae Plato. Perto do canto esquerdo inferior, está localizado Vallis Alpes, um incrível vale lunar que divide a cordilheira dos Montes Alpes. Estende-se por 166 km desde a bacia do Mare Imbrium. O vale é estreito em ambas as extremidades e se alarga até uma largura máxima de cerca de 10 km ao longo do trecho intermédio. O fundo do vale é uma superfície plana inundada de lava que é dividida ao meio por um canal fino, quebrado e semelhante a uma fenda. Os lados do vale elevam-se do solo até o terreno montanhoso circundante, uma superfície irregular e em blocos.

A lunar Scene Shows a Close-up Sharp View of Copernicus Crater
Captured on March 23, 2021 from Dark Sky® Alqueva Observatory, in Cumeada village, Portugal, on a very steady night, the close-up view shows a high-resolution sharp view of Copernicus crater. Visible slightly northwest of the center of the Moon’s Earth-facing hemisphere, Copernicus is an impact crater located on the eastern Oceanus Procellarum. With a diameter of 96,1km and a depth of 3.8 km, it may have been created by debris from the breakup of the parent body of asteroid 495 Eulalia, around 800 million years ago. The circular rim has a discernible hexagonal form, with a terraced inner wall and a 30 km wide, sloping rampart that descends nearly a kilometer to the surrounding mare. There are three distinct terraces visible, and arc-shaped landslides due to slumping of the inner wall as the crater debris subsided. Most likely due to its recent formation, the crater floor has not been flooded by lava. The terrain along the bottom is hilly in the upper part, while the other half is relatively smooth. The central peaks separated from each other by valleys, consist of three isolated mountainous rises climbing as high as 1.2 km above the floor. The crater rays spread as far as 800 kilometers across the surrounding mare, overlying rays from the craters Aristarchus and Kepler. The data on this description are based in the data of Lunar Orbiter 5, Terry W. Offield of the U.S. Geological Survey.
PT: Captada em 23 de Março de 2021 a partir do Observatório da Cumeada, no Dark Sky® Alqueva, Portugal, numa noite com a atmosfera muito estável, mostra uma visão nítida em alta resolução da cratera Copernicus. Visível ligeiramente a noroeste do centro do hemisfério da Lua que está voltado para a Terra, Copernicus é uma cratera de impacto localizada ana região Este do Oceanus Procellarum. Com um diâmetro de 96,1 km e uma profundidade de 3,8 km, pode ter sido criada por destroços do asteróide 495 Eulália, há cerca de 800 milhões de anos atrás. As paredes externas circulares têm uma forma hexagonal perceptível, com uma parede interna em forma de terraço e uma muralha inclinada de 30 km de largura que desce quase um quilômetro até o mar circundante. Existem três terraços distintos visíveis e deslizamentos de terra em forma de arco devido à queda da parede interna à medida que os detritos da cratera diminuíram. Muito provavelmente, devido à sua formação recente, o fundo da cratera não foi inundado por lava. O terreno ao longo do fundo é acidentado na parte superior, enquanto a outra metade é relativamente plana. Os picos centrais separados uns dos outros por vales, consistem em três elevações montanhosas isoladas que chegam a 1,2 km acima do solo. Os raios de impacto da cratera estenderam-se até 800 quilômetros ao redor do mar, sobrepondo-se aos raios das crateras Aristarchus e Kepler. Os dados utlizados na pormenorização desta cratera baseiam-se nos dados do Lunar Orbiter 5, e na descrição detalhada do Terry W. Offield do U.S. Geological Survey.

Clavius and Moretus in a Sharp Lunarscape Scene
Like if we were making an orbital flight over the moon, the image captured on March 23, 2021 from Dark Sky® Alqueva Observatory, in Cumeada village, Portugal, on a very steady night, shows a high-resolution sharp view of Clavius along with Moretus craters framed in the same scene. Being Clavius one of the largest and older formations on the lunar surface, features a diameter of 230.8Km and a Depth of 3.5 km, and it was formed during the Nectarian period. The convex plain floor was flooded with lava at about 4 billion years ago, it has a low outer wall comparing to its size, marked by some small and large crater impacts, like the detailed Rutherfurd visible in the upper part of the crater wall with a diameter of 47,4km and depth of 2,5km, as well as Porter – lower part of the crater wall near the lower egde of the image – with 51,3km in diameter. Last October 2020, NASA has announced and confirmed the existence of a molecular water near Clavius. But this lunarscape scene also shows another very interesting crater, Moretus – upper right corner – with a diameter of 114km. Due to the location near the lunar limb, the crater appears oblong because of foreshortening. The rim of the crater has a wide, terraced inner wall, and a complex outer rampart. The floor has been partly resurfaced and is relatively flat. In the middle is a central mountain formation that rises about 2.1 kilometers above the surrounding floor.

Sendo Clavius uma das maiores e mais antigas formações na superfície lunar, apresentando um diâmetro de 230,8 km e uma profundidade de 3,5 km, foi formada durante o período Nectárico, na escala do período geológico lunar. O chão plano e convexo foi inundado com lava há cerca de 4 mil milhões de anos atrás, revelando uma parede externa baixa comparada com o seu tamanho total, marcada por alguns impactos que formaram pequenas e grandes crateras, como a detalhada Rutherfurd visível na parte superior da parede da cratera com um diâmetro de 47,4km e uma profundidade de 2,5km, assim como a Porter – visível na parte inferior da parede da cratera, próxima à parte inferior da imagem – com 51,3km de diâmetro. Em outubro de 2020, a NASA anunciou e confirmou a existência de uma molécula de águra perto de Clavius. Mas esta paisagem lunar também mostra outra cratera muito interessante, Moretus, com um diâmetro de 114 km. Devido à localização próxima ao limbo lunar, a cratera parece oblonga devido à perspectiva. O extremo da cratera tem uma parede interna ampla e em terraço, assim como uma muralha externa complexa. O piso foi parcialmente recapeado e é relativamente plano. No meio está uma formação montanhosa central que se eleva a cerca de 2,1 quilémetros acima do solo circundante.
