오늘의 NASA 우주 사진 (2022-06-05)

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

 

이 사진의 제목은 Two Black Holes Dancing in 3C 75 입니다. NASA에서 제공한 공식 설명은 아래와 같습니다.

 

What's happening at the center of active galaxy 3C 75? The two bright sources at the center of this composite x-ray (blue)/ radio (pink) image are co-orbiting supermassive black holes powering the giant radio source 3C 75. Surrounded by multimillion degree x-ray emitting gas, and blasting out jets of relativistic particles the supermassive black holes are separated by 25,000 light-years. At the cores of two merging galaxies in the Abell 400 galaxy cluster they are some 300 million light-years away. Astronomers conclude that these two supermassive black holes are bound together by gravity in a binary system in part because the jets' consistent swept back appearance is most likely due to their common motion as they speed through the hot cluster gas at about 1200 kilometers per second. Such spectacular cosmic mergers are thought to be common in crowded galaxy cluster environments in the distant universe. In their final stages, the mergers are expected to be intense sources of gravitational waves.

 

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!
