NASA 나사의 오늘의 이미지들 (2023-10-07)

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

 

해당 사진의 이름은 The Once and Future Stars of Andromeda 인데요 우선 NASA에서 공식적으로 발표한 설명들을 확인해 보겠습니다

 

This picture of Andromeda shows not only where stars are now, but where stars will be. The big, beautiful Andromeda Galaxy, M31, is a spiral galaxy a mere 2.5 million light-years away. Image data from space-based and ground-based observatories have been combined here to produce this intriguing composite view of Andromeda at wavelengths both inside and outside normally visible light. The visible light shows where M31's stars are now, highlighted in white and blue hues and imaged by the Hubble, Subaru, and Mayall telescopes. The infrared light shows where M31's future stars will soon form, highlighted in orange hues and imaged by NASA's Spitzer Space Telescope. The infrared light tracks enormous lanes of dust, warmed by stars, sweeping along Andromeda's spiral arms. This dust is a tracer of the galaxy's vast interstellar gas, raw material for future star formation. Of course, the new stars will likely form over the next hundred million years or so. That's well before Andromeda merges with our Milky Way Galaxy in about 5 billion years.

 

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
