NASA 나사의 오늘의 이미지들 (2023-12-20)

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

 

해당 사진의 이름은 Ice Halos over Bavaria 인데요 우선 NASA에서 공식적으로 발표한 설명들을 확인해 보겠습니다

 

What's causing those unusual sky arcs? Ice crystals. While crossing a field of fresh snow near Füssen, Bavaria, Germany, earlier this month, the photographer noticed that he had entered an ice fog. For suspended water to freeze into an ice fog requires quite cold temperatures, and indeed the air temperature on this day was measured at well below zero. The ice fog reflected light from the Sun setting behind St. Coleman Church. The result was one of the greatest spectacles the photographer has ever seen. First, the spots in the featured picture are not background stars but suspended ice and snow. Next, two prominent ice halos are visible: the 22-degree halo and the 46-degree halo. Multiple arcs are also visible, including, from top to bottom, antisolar (subsun), circumzenithal, Parry, tangent, and parhelic (horizontal). Finally, the balloon shaped curve connecting the top arc to the Sun is the rarest of all: it is the heliac arc, created by reflection from the sides of hexagonally shaped ice crystals suspended in a horizontal orientation.

 

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
