오늘의 우주 사진 (2022-10-17)

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

 

이 사진의 이름은 X-Ray Rings Around a Gamma Ray Burst 인데요 국제기구인 NASA에서도 공식 자료를 확인해보도록 하겠습니다

 

Why would x-ray rings appear around a gamma-ray burst? The surprising answer has little to do with the explosion itself but rather with light reflected off areas of dust-laden gas in our own Milky Way Galaxy. GRB 221009A was a tremendous explosion -- a very bright gamma-ray burst (GRB) that occurred far across the universe with radiation just arriving in our Solar System last week. Since GRBs can also emit copious amounts of x-rays, a bright flash of x-rays arrived nearly simultaneously with the gamma-radiation. In this case, the X-rays also bounced off regions high in dust right here in our Milky Way Galaxy, creating the unusual reflections. The greater the angle between reflecting Milky Way dust and the GRB, the greater the radius of the X-ray rings, and, typically, the longer it takes for these light-echoes to arrive.

 

이번에도 광대한 우주크기에 인간이 얼마나 작은지 확인하게 되는 사건입니다
그러면 다음시간에 더 좋은 정보들을 들고 오도록 하겠습니다 행복한 지구여행 되시길 바랍니다
