NASA 오늘의 사진(2023-07-17)

안녕하세요, 프리덤 알제이입니다. 

오늘은 NASA에서 어떤 우주의 모습을 보여주는지 궁금합니다.

이 사진의 제목은 Shells and Arcs around Star CW Leonis 입니다. 

NASA에서의 공식적으로 제공한 설명을 보시죠.

 

<What's happening around this star? No one is sure. CW Leonis is the closest carbon star, a star that appears orange because of atmospheric carbon dispersed from interior nuclear fusion. But CW Leonis also appears engulfed in a gaseous carbon-rich nebula. What causes the nebula's complexity is unknown, but its geometry of shells and arcs are surely intriguing. The featured image by the Hubble Space Telescope details this complexity. The low surface gravity of carbon stars enhances their ability to expel carbon and carbon compounds into space. Some of this carbon ends up forming dark dust that is commonly seen in the nebulas of young star-forming regions and the disks of galaxies. Humans and all Earth-based life are carbon-based, and at least some of our carbon was likely once circulating in the atmospheres of near-death stars like carbon stars.;

 

오늘도 흥미로운 우주, 광할한 우주영상을 보며, 그 우주에 살고있는 저희가 위대해 보입니다.

오늘도 즐거운 하루 되시고, 우주 영상/사진은 꾸준히 업로드 되니 꼭 또 구경오세요.
