NASA 나사의 오늘의 이미지들 (2022-09-18)

안녕하세요, 잡학다식 입니다. 오늘은 과연 나사에서 어떤 방식으로 우주의 형상을 표현해 줄까요?
우선 이미지부터 볼 수 있도록 하겠습니다

 

해당 사진의 이름은 Analemma over the Callanish Stones 인데요 우선 NASA에서 공식적으로 발표한 설명들을 확인해 보겠습니다

 

If you went outside at the same time every day and took a picture that included the Sun, how would the Sun's position change? A more visual answer to that question is an analemma, a composite image taken from the same spot at the same time over the course of a year. The featured analemma was composed from images taken every few days at noon near the village of Callanish in the Outer Hebrides in Scotland, UK. In the foreground are the Callanish Stones, a stone circle built around 2700 BC during humanity's Bronze Age. It is not known if the placement of the Callanish Stones has or had astronomical significance. The ultimate causes for the figure-8 shape of this and all analemmas are the tilt of the Earth axis and the ellipticity of the Earth's orbit around the Sun. At the solstices, the Sun will appear at the top or bottom of an analemma. The featured image was taken near the December solstice and so the Sun appears near the bottom. Equinoxes, however, correspond to analemma middle points -- not the intersection point. This coming Friday at 1:04 am (UT) -- Thursday in the Americas -- is the equinox ("equal night"), when day and night are equal over all of planet Earth. Many cultures celebrate a change of season at an equinox. Explore Your Universe: Random APOD Generator

 

이번에도 광활한 우주 앞에 인간이 얼마나 작은 존재인지 다시 한번 알게 되는것 같습니다
저는 내일도 더 좋은 사진과 함께 돌아오겠습니다, 그럼 행목한 하루 되시길 바랍니다
