NASA의 오늘의 우주사진 (2023-07-25)

안녕하세요, 대디스입니다. 오늘은 NASA에서 어떤 우주의 모습을 비춰줄까요?
먼저 사진부터 감상하시죠~

 

이 사진의 제목은 The Eagle Nebula with X-ray Hot Stars 입니다. NASA에서 공식적으로 제공한 설명을 보시죠.

 

What do the famous Eagle Nebula star pillars look like in X-ray light? To find out, NASA's orbiting Chandra X-ray Observatory peered in and through these interstellar mountains of star formation. It was found that in M16 the dust pillars themselves do not emit many X-rays, but a lot of small-but-bright X-ray sources became evident. These sources are shown as bright dots on the featured image which is a composite of exposures from Chandra (X-rays), XMM (X-rays), JWST (infrared), Spitzer (infrared), Hubble (visible), and the VLT (visible). What stars produce these X-rays remains a topic of research, but some are hypothesized to be hot, recently-formed, low-mass stars, while others are thought to be hot, older, high-mass stars. These X-ray hot stars are scattered around the frame -- the previously identified Evaporating Gaseous Globules (EGGS) seen in visible light are not currently hot enough to emit X-rays.

 

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