오늘의 NASA 우주 사진 (2022-07-20)

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

 

이 사진의 제목은 Jupiter and Ring in Infrared from Webb 입니다. NASA에서 제공한 공식 설명은 아래와 같습니다.

 

Why does Jupiter have rings? Jupiter's main ring was discovered in 1979 by NASA's passing Voyager 1 spacecraft, but its origin was then a mystery. Data from NASA's Galileo spacecraft that orbited Jupiter from 1995 to 2003, however, confirmed the hypothesis that this ring was created by meteoroid impacts on small nearby moons. As a small meteoroid strikes tiny Metis, for example, it will bore into the moon, vaporize, and explode dirt and dust off into a Jovian orbit. The featured image of Jupiter in infrared light by the James Webb Space Telescope shows not only Jupiter and its clouds, but this ring as well. Also visible is Jupiter's Great Red Spot (GRS) -- in comparatively light color on the right, Jupiter's large moon Europa -- in the center of diffraction spikes on the left, and Europa's shadow -- next to the GRS. Several features in the image are not yet well understood, including the seemingly separated cloud layer on Jupiter's right limb. Celestial Surprise: What picture did APOD feature on your birthday?

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!
