오늘의 NASA 우주 사진 (2021-12-27)

안녕하세요, 히제입니다.
오늘 NASA에서 비춰주는 우주의 모습은 어떠할까요?
사진 먼저 감상하시죠!

 

이 사진의 제목은 Comet Leonard behind JWST Launch Plume 입니다. NASA에서 제공한 공식 설명은 아래와 같습니다.

 

Which one of these two streaks is a comet? Although they both have comet-like features, the lower streak is the only real comet. This lower streak shows the coma and tail of Comet Leonard, a city-sized block of rocky ice that is passing through the inner Solar System as it continues its looping orbit around the Sun. Comet Leonard has recently passed its closest to both the Earth and Venus and will round the Sun next week. The comet, still visible to the unaided eye, has developed a long and changing tail in recent weeks. In contrast, the upper streak is the launch plume of the Ariane V rocket that lifted the James Webb Space Telescope (JWST) off the Earth two days ago. The featured single-exposure image was taken from Thailand, and the foreground spire is atop a pagoda in Doi Inthanon National Park. JWST, NASA's largest and most powerful space telescope so far, will orbit the Sun near the Earth-Sun L2 point and is scheduled to start science observations in the summer of 2022.

우주 사진을 볼 때마다, 끝을 알 수 없는 저 광활한 우주 속에서 우리 사람이란 존재가 얼마나 작은 부분인가 실감하게 됩니다.
그럼 저는 내일 또 새로운 우주 사진과 함께 돌아오겠습니다:-) 좋은 하루 되세요!
