오늘의 NASA 우주 사진 (2023-02-24)

안녕하세요, 히제입니다.
오늘 NASA에서 비춰주는 우주의 모습은 어떠할까요?
사진 먼저 감상하시죠!

 

이 사진의 제목은 Jones-Emberson 1 입니다. NASA에서 제공한 공식 설명은 아래와 같습니다.

 

Planetary nebula Jones-Emberson 1 is the death shroud of a dying Sun-like star. It lies some 1,600 light-years from Earth toward the sharp-eyed constellation Lynx. About 4 light-years across, the expanding remnant of the dying star's atmosphere was shrugged off into interstellar space, as the star's central supply of hydrogen and then helium for fusion was finally depleted after billions of years. Visible near the center of the planetary nebula is what remains of the stellar core, a blue-hot white dwarf star. Also known as PK 164 +31.1, the nebula is faint and very difficult to glimpse at a telescope's eyepiece. But this deep broadband image combining 22 hours of exposure time does show it off in exceptional detail. Stars within our own Milky Way galaxy as well as background galaxies across the universe are scattered through the clear field of view. Ephemeral on the cosmic stage, Jones-Emberson 1 will fade away over the next few thousand years. Its hot, central white dwarf star will take billions of years to cool.

 

우주 사진을 볼 때마다, 끝을 알 수 없는 저 광활한 우주 속에서 우리 사람이란 존재가 얼마나 작은 부분인가 실감하게 됩니다.
그럼 저는 내일 또 새로운 우주 사진과 함께 돌아오겠습니다:-) 좋은 하루 되세요!
