안녕하세요, 프리덤 알제이입니다. 

오늘은 NASA에서 어떤 우주의 모습을 보여주는지 궁금합니다.

이 사진의 제목은 Ice Halos over Bavaria 입니다. 

NASA에서의 공식적으로 제공한 설명을 보시죠.

 

<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.;

 

오늘도 흥미로운 우주, 광할한 우주영상을 보며, 그 우주에 살고있는 저희가 위대해 보입니다.

오늘도 즐거운 하루 되시고, 우주 영상/사진은 꾸준히 업로드 되니 꼭 또 구경오세요.
