NASA 나사의 오늘의 이미지들 (2023-07-05)

안녕하세요, 잡학다식 입니다. 오늘은 과연 나사에서 어떤 방식으로 우주의 형상을 표현해 줄까요?
우선 이미지부터 볼 수 있도록 하겠습니다

 

해당 사진의 이름은 A Map of the Observable Universe 인데요 우선 NASA에서 공식적으로 발표한 설명들을 확인해 보겠습니다

 

What if you could see out to the edge of the observable universe? You would see galaxies, galaxies, galaxies, and then, well, quasars, which are the bright centers of distant galaxies. To expand understanding of the very largest scales that humanity can see, a map of the galaxies and quasars found by the Sloan Digital Sky Survey from 2000 to 2020 -- out to near the edge of the observable universe -- has been composed. Featured here, one wedge from this survey encompasses about 200,000 galaxies and quasars out beyond a look-back time of 12 billion years and cosmological redshift 5. Almost every dot in the nearby lower part of the illustration represents a galaxy, with redness indicating increasing redshift and distance. Similarly, almost every dot on the upper part represents a distant quasar, with blue-shaded dots being closer than red. Clearly shown among many discoveries, gravity between galaxies has caused the nearby universe to condense and become increasingly more filamentary than the distant universe.

이번에도 광활한 우주 앞에 인간이 얼마나 작은 존재인지 다시 한번 알게 되는것 같습니다
저는 내일도 더 좋은 사진과 함께 돌아오겠습니다, 그럼 행목한 하루 되시길 바랍니다
