NASA 오늘의 사진(2023-12-27)

안녕하세요, 프리덤 알제이입니다. 

오늘은 NASA에서 어떤 우주의 모습을 보여주는지 궁금합니다.

이 사진의 제목은 Rainbow Aurora over Icelandic Waterfall 입니다. 

NASA에서의 공식적으로 제공한 설명을 보시죠.

 

<Yes, but can your aurora do this? First, yes, auroras can look like rainbows even though they are completely different phenomena. Auroras are caused by Sun-created particles being channeled into Earth's atmosphere by Earth's magnetic field, and create colors by exciting atoms at different heights. Conversely, rainbows are created by sunlight backscattering off falling raindrops, and different colors are refracted by slightly different angles. Unfortunately, auroras can’t create waterfalls, but if you plan well and are lucky enough, you can photograph them together. The featured picture is composed of several images taken on the same night last month near the Skógafoss waterfall in Iceland. The planning centered on capturing the central band of our Milky Way galaxy over the picturesque cascade. By luck, a spectacular aurora soon appeared just below the curving arch of the Milky Way. Far in the background, the Pleiades star cluster and the Andromeda galaxy can be found. Your Sky Surprise: What picture did APOD feature on your birthday? (post 1995);

 

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.
