안녕하세요, 프리덤 알제이입니다. 

오늘은 NASA에서 어떤 우주의 모습을 보여주는지 궁금합니다.

이 사진의 제목은 MyCn 18: The Engraved Hourglass Planetary Nebula 입니다. 

NASA에서의 공식적으로 제공한 설명을 보시죠.

 

<Do you see the hourglass shape -- or does it see you? If you can picture it, the rings of MyCn 18 trace the outline of an hourglass -- although one with an unusual eye in its center. Either way, the sands of time are running out for the central star of this hourglass-shaped planetary nebula. With its nuclear fuel exhausted, this brief, spectacular, closing phase of a Sun-like star's life occurs as its outer layers are ejected - its core becoming a cooling, fading white dwarf. In 1995, astronomers used the Hubble Space Telescope (HST) to make a series of images of planetary nebulae, including the one featured here. Pictured, delicate rings of colorful glowing gas (nitrogen-red, hydrogen-green, and oxygen-blue) outline the tenuous walls of the hourglass. The unprecedented sharpness of the Hubble images has revealed surprising details of the nebula ejection process that are helping to resolve the outstanding mysteries of the complex shapes and symmetries of planetary nebulas like MyCn 18.;

 

오늘도 흥미로운 우주, 광할한 우주영상을 보며, 그 우주에 살고있는 저희가 위대해 보입니다.

오늘도 즐거운 하루 되시고, 우주 영상/사진은 꾸준히 업로드 되니 꼭 또 구경오세요.
