오늘의 우주 사진 (2022-10-12)

최근 NASA에서 우주 모습을 알려줬는데요 과연 어떻게 보여질지 기대가 됩니다
그러면 지금부터 이미지를 살펴보겠습니다

 

이 사진의 이름은 Ou4: The Giant Squid Nebula 인데요 국제기구인 NASA에서도 공식 자료를 확인해보도록 하겠습니다

 

A mysterious squid-like cosmic cloud, this nebula is very faint, but also very large in planet Earth's sky. In the image, composed with 30 hours of narrowband image data, it spans nearly three full moons toward the royal constellation Cepheus. Discovered in 2011 by French astro-imager Nicolas Outters, the Squid Nebula's bipolar shape is distinguished here by the telltale blue-green emission from doubly ionized oxygen atoms. Though apparently surrounded by the reddish hydrogen emission region Sh2-129, the true distance and nature of the Squid Nebula have been difficult to determine. Still, a more recent investigation suggests Ou4 really does lie within Sh2-129 some 2,300 light-years away. Consistent with that scenario, the cosmic squid would represent a spectacular outflow of material driven by a triple system of hot, massive stars, cataloged as HR8119, seen near the center of the nebula. If so, this truly giant squid nebula would physically be over 50 light-years across.

 

이번에도 광대한 우주크기에 인간이 얼마나 작은지 확인하게 되는 사건입니다
