NASA에서 보낸 오늘의 우주 사진 (2023-07-27)

안녕하세요, 화이트입니다. 오늘은 NASA에서 어떤 우주의 모습을 비춰줄까요?
먼저 사진부터 감상하시죠!

 

이 사진의 제목은 Galaxies in the River 입니다. NASA에서 공식적으로 제공한 설명을 보시죠.

 

Large galaxies grow by eating small ones. Even our own galaxy engages in a sort of galactic cannibalism, absorbing small galaxies that are too close and are captured by the Milky Way's gravity. In fact, the practice is common in the universe and illustrated by this striking pair of interacting galaxies from the banks of the southern constellation Eridanus, The River. Located over 50 million light years away, the large, distorted spiral NGC 1532 is seen locked in a gravitational struggle with dwarf galaxy NGC 1531, a struggle the smaller galaxy will eventually lose. Seen nearly edge-on, spiral NGC 1532 spans about 100,000 light-years. The merging galaxies are captured in this sharp image from the Dark Energy Camera mounted on the National Science Foundation’s Blanco 4-meter Telescope at Cerro Tololo Inter-American Observatory in Chile. The NGC 1532/1531 pair is thought to be similar to the well-studied system of face-on spiral and small companion known as M51.

오늘도 광활한 우주 앞에 인간이 얼마나 작은 존재인지 깨닫게 되네요.
저는 내일도 더 좋은 사진과 함께 돌아오겠습니다, 행복한 지구여행 되세요!
