아름답고 멋진 우주사진 2022년 05월 21일

2022년 05월 21일자 도착할 우주여행 장소는 사진에 나온 장소입니다.

여기는 Planetary Nebula Abell 7 입니다. 

 

 

Very faint planetary nebula Abell 7 is some 1,800 light-years distant, just south of Orion in planet Earth's skies in the constellation Lepus, The Hare. Surrounded by Milky Way stars and near the line-of-sight to distant background galaxies, its generally simple spherical shape, about 8 light-years in diameter, is outlined in this deep telescopic image. Within its confines are beautiful, more complex details enhanced by the use of narrowband filters. Emission from hydrogen is shown in reddish hues with oxygen emission mapped to green and blue colors, giving Abell 7 a natural appearance that would otherwise be much too faint to be appreciated by eye. A planetary nebula represents a very brief final phase in stellar evolution that our own Sun will experience 5 billion years hence, as the nebula's central, once sun-like star shrugs off its outer layers. Abell 7 itself is estimated to be 20,000 years old. Its central star is seen here as a fading white dwarf some 10 billion years old.

 

멋지고 아름다운 우주여행에 탑승해주셔서 감사합니다.

다음에도 멋진 장소로 모실 수 있도록 노력하겠습니다.
