A View From Up Close: The Concept of the Cosmos and Celestial Bodies as Culturally Tamed WorldThe concept of the cosmos, shaped in ancient Greek philosophy, has a different meaning today. This change of meaning reflects rejection of the idea of the cosmos as order established by the gods. The author of the article, as a cultural anthropologist and amateur astronomer, describes this problem by analyzing selected examples of the concepts of the cosmos and of celestial bodies, such as Venus and Sirius. These concepts are examples of alternative knowledge that was an important component of cultural systems. Also touched upon in the article are issues of epistemology and philosophy of science. Spojrzenie z bliska. Koncepcja kosmosu i ciał niebieskich jako świata oswojonego kulturowoPojęcie kosmosu ukształtowane w starożytnej filozofii greckiej ma współcześnie odmienną treść, co odzwierciedla porzucenie idei kosmosu jako ustanowionego przez bogów porządku. Autor artykułu, jako antropolog kulturowy i adept astronomii, opisuje ten problem, analizując wybrane koncepcje kosmosu oraz takich ciał niebieskich, jak Wenus czy Syriusz. Koncepcje te to przykłady alternatywnej wiedzy, która była ważnym składnikiem systemów kulturowych. Na drugim planie podjętych w tym artykule rozważań brane są pod uwagę kwestie dotyczące epistemologii i filozofii nauki.

James Hall Nasmyth (1808–1890) was an accomplished engineer and amateur astronomer. The culmination of Nasmyth's drawings from telescopic observation, the advent of photomechanical print processes, and his interest in the causative features of the lunar surface, led to the 1874 publication of The Moon: Considered as a Planet, a World, and a Satellite. This thesis provides a comprehensive catalogue of the lunar illustrations in the first three editions, revealing the aesthetic variations in the illustrative plates due to reproduction and print processes used. These processes include: engraving, photogravure, heliotype, lithograph, chromolithograph, and four different variations of the Woodburytype. The editions are contextualized using scientific photographs as illustrations, through a discussion of astronomy, book production, and Nasmyth's biography. Through an examination of Nasmyth's use of photography and permanent print processes, this thesis argues that his lunar illustrations remain an important scientific contribution.

<p>JunoCam, the visible imager on the Juno mission’s payload that was designed primarily for public-outreach purposes, continues to produce images of Jupiter that provide unexpected scientific benefits.  Juno’s polar orbits enable observing regions of the planet that have not previously been detected at such high resolution by any previous spacecraft. JunoCam has a single CCD detector with an integral color-strip filter that enables the instrument to image in four color bands—blue, green, red and an 889-nm methane band.  JunoCam maps a field of view of 58° across the width of the detector, perpendicular to the spacecraft scan direction. We will describe characteristics and likely origins of bright white compact (~50 km) clouds, informally dubbed “pop-up” clouds by the JunoCam team.  We used the length of shadows of these and other features to determine the relative heights of clouds and assigned a provisional chemical classification based on relative altitudes from equilibrium-chemistry predictions. We tracked the continued interactions of small anticyclonic ovals with Jupiter’s Great Red Spot (GRS) that drew off high-altitude reddish haze into strips (commonly called “flakes”) on its western edge.  A lightning flash was detected in one of the compact circumpolar cyclones in late December. Observations of the south-polar circumpolar cyclones showed that the original unequally sided pentagon becoming a hexagon – with a cyclone filling in an open area, then a pentagon again over the course of 110 days.  In a collaboration with amateur astronomer Clyde Foster (S. Africa), we observed the morphology of an unexpected upwelling in late May of 2020, now known as “Clyde’s Spot”, and tracked its evolution in concert with several ground-based observations.  We also measured ~40-50 m/s winds around the sinuous jet bounding the South Polar Hood, an upper-level haze generated by auroral-related chemistry.  Lightly processed and raw JunoCam data continue to be posted on the JunoCam webpage at https://missionjuno.swri.edu/junocam/processing.   Citizen scientists download these images and upload their processed contributions.</p>

A more than 50 kilometer span of space at moon surface is observed as densely littered with fossils of Mesozoic Era , which has been traced by Jagmohan saxena an amateur astronomer. It may raise a new debate of evolution of Moon , Animals & Flora Fauna there of.This area is identified at South pole (Near side)- between the crater Mazinus E to Bogu lawsky H crater and at Nusl S crater. These are the areas which are densely littered with Dinosaur fossils along with other animals of Mesozoic Era. It may be possible that fossils of flora and fauna of Mesozoic Era may also be found at the site.The fossils found under the Moon surface are likely identified as a skull of T-Rex, and 2 Skeleton of Brechosaurus, one skeleton of Protoceratopsian one more skull and one piece of probably protoceratopsian, with bone joint structure is also observed. These have been observed under the surface of the moon.Though the huge area of moon is identified to be littered with such type of big animal fossils of Mesozoic Era. But the area where clear structures are visible separately, have been reported here.This finding may raise the question about the formation of Moon. Has the moon been formed just 6.5 crores years before. Or has it been littered by fossils through some asteroids departed from Earth. Or it's been the parallel evolution of Dinosaurs at Earth and Moon simultaneously . It might be the matter of further studies and discussion. Because there has been a wast gap between the period of evolution of moon and Dinosaurs. As moon is supposed to come in Existence 4.5 billion years ago whereas Dinosaur are supposed to come in existence just few crores of years ago.(as per table attached).What period are these relics, how did they reach the moon. Is the sequence of destruction of Dinosaur on Earth related to the derivation of the moon? All these points generate deep curiosity. Which will enable us to enrich future science more.

Is moon littered with Dinosaur fossils? Yes, First reporting of the Dinosaur fossils has been made by Jagmohan Saxena of Bikaner India. It has been observed by mrJagmohan that there are some areas which are littered with bony fossils, a careful 6 has made it confirmed that these have been very possible fossils of Mesozoic Era. This is first ever such claim by an amateur astronomer jagmohan saxena . He has supported his claim by siting the coordinates of site at Moon.Though the period of origin of Moon and evolution of Dinosaurs are too different from each other,which may be enough to raise the debate is it possible, that there are fossils on moon.Some magical it sedimentary effect.But the facts couldn't be denied.

This chapter details how astronomers fell in love with Mars during the very earliest years of the age of telescopes because it could appear quite large when viewed through the lens, as it is closer to Earth than all other planets. It discusses the astronomers that gained knowledge about the physical properties of Mars by the end of the eighteenth century that were convinced that Earth and Mars could be thought of as twins. It also recounts the first claimed telescopic detection of a black spot on Mars' surface in 1636 and again in 1638 by amateur astronomer Francesco Fontana. The chapter explains how Fontana's dark spot drew the attention of other astronomers to Mars as an object of interest with the potential to show observers something other than a bland, featureless disk. It refers to astronomers armed with telescopes who scould peer through the depths of space and unravel the mysteries of the red planet.
