NASA에서 보낸 오늘의 우주 사진 (2022-07-18)

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

 

이 사진의 제목은 Stephan's Quintet from Webb, Hubble, and Subaru 입니다. NASA에서 공식적으로 제공한 설명을 보시죠.

 

OK, but why can't you combine images from Webb and Hubble? You can, and today's featured image shows one impressive result. Although the recently launched James Webb Space Telescope (Webb) has a larger mirror than Hubble, it specializes in infrared light and can't see blue -- only up to about orange. Conversely, the Hubble Space Telescope (Hubble) has a smaller mirror than Webb and can't see as far into the infrared as Webb, but can image not only blue light but even ultraviolet. Therefore, Webb and Hubble data can be combined to create images across a wider variety of colors. The featured image of four galaxies from Stephan's Quintet shows Webb images as red and also includes images taken by Japan's ground-based Subaru telescope in Hawaii. Because image data for Webb, Hubble, and Subaru are made freely available, anyone around the world can process it themselves, and even create intriguing and scientifically useful multi-observatory montages.

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