오늘의 NASA 우주 사진 (2023-05-02)

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

 

이 사진의 제목은 Flat Rock Hills on Mars 입니다. NASA에서 제공한 공식 설명은 아래와 같습니다.

 

Why are there so many flat rocks on Mars? Some views of plains and hills on Mars show many rocks that are unusually flat when compared to rocks on Earth. One reason for this is a process that is common to both Mars and Earth: erosion. The carbon-dioxide wind on Mars can act like sandpaper when it blows around gritty Martian sand. This sand can create differential erosion, smoothing over some rocks, while wearing down the tops of other long-exposed stones. The featured image capturing several hills covered with flat-topped rocks was taken last month by NASA's Curiosity Rover on Mars. This robotic rover has now been rolling across Mars for ten years and has helped uncover many details of the wet and windy past of Earth's planetary neighbor. After taking this and other images, Curiosity carefully navigated stones and slippery sand to climb up Marker Band Valley.

 

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!
