NASA 오늘의 사진 (2022-07-06)

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

 

이 사진의 제목은 Milky Way Motion in 3D from Gaia 입니다. NASA에서 공식적으로 제공한 설명을 보시죠.

 

Our sky is alive with the streams of stars. The motions of 26 million Milky Way stars are evident in the featured map constructed from recent data taken by ESA's Gaia satellite. Stars colored blue are moving toward us, while red indicates away. Lines depict the motion of the stars across the sky. The large blue on the left and red areas on the map's right give the overall impression that stars in the Milky Way are rotating around the center. However, there is a region near the middle -- caused by our own Sun's motion relative to a rigidly-rotating central Galactic bar -- that seems to reverse it. Understanding details about the motion of stars is helping humanity to better understand the complex history of our Milky Way galaxy and the origin of our Sun.

 

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