안녕하세요. 겨울인데 겨울날씨 같지가 않네요.
오늘은 사진 감상을 한번 해보려고 해요. NASA에서 보내준 사진.
이 사진의 타이틀을 보면, The Butterfly Nebula from Hubble 입니다. NASA에서는 어떻게 이 사진을 설명하고 있나 볼게요.
Stars can make beautiful patterns as they age -- sometimes similar to flowers or insects. NGC 6302, the Butterfly Nebula, is a notable example. Though its gaseous wingspan covers over 3 light-years and its estimated surface temperature exceeds 200,000 degrees C, the aging central star of NGC 6302, the featured planetary nebula, has become exceptionally hot, shining brightly in visible and ultraviolet light but hidden from direct view by a dense torus of dust. This sharp close-up was recorded by the Hubble Space Telescope and is processed here to show off remarkable details of the complex planetary nebula, highlighting in particular light emitted by oxygen (shown as blue), hydrogen (green), and nitrogen (red). NGC 6302 lies about 3,500 light-years away in the arachnologically correct constellation of the Scorpion (Scorpius). Planetary nebulas evolve from outer atmospheres of stars like our Sun, but usually fade in about 20,000 years.
저는 어릴때 우주비행사가 꿈이었어요. 하하하.
꿈은 꿈일뿐.ㅠㅠ 동경 같은 것이죠. 지금 우주비행사가 된다고 생각하면 너무 무서워요. ㅠㅠ 오늘도 좋은 하루 되세요!
