오늘의 우주 사진 (2023-09-23)

최근 NASA에서 우주 모습을 알려줬는데요 과연 어떻게 보여질지 기대가 됩니다
그러면 지금부터 이미지를 살펴보겠습니다

 

이 사진의 이름은 Afternoon Analemma 인데요 국제기구인 NASA에서도 공식 자료를 확인해보도록 하겠습니다

 

An analemma is that figure-8 curve you get when you mark the position of the Sun at the same time each day for one year. To make this one, a 4x5 pinhole camera was set up looking north in southern New Zealand skies. The shutter was briefly opened each clear day in the afternoon at 4pm local time exposing the same photosensitized glass plate for the year spanning September 23, 2022 to September 19, 2023. On two days, the winter and summer solstices, the shutter was opened again 15 minutes after the main exposure and remained open until sunset to create the sun trails at the bottom and top of the curve. The equinox dates correspond to positions in the middle of the curve, not the crossover point. Of course, the curve itself is inverted compared to an analemma traced from the northern hemisphere. And while fall begins today at the Autumnal Equinox for the northern hemisphere, it's the Spring Equinox in the south.

 

이번에도 광대한 우주크기에 인간이 얼마나 작은지 확인하게 되는 사건입니다
그러면 다음시간에 더 좋은 정보들을 들고 오도록 하겠습니다 행복한 지구여행 되시길 바랍니다
