아름답고 멋진 우주사진 2022년 07월 31일

2022년 07월 31일자 도착할 우주여행 장소는 사진에 나온 장소입니다.

여기는 Starburst Galaxy M94 from Hubble 입니다. 

 

 

Why does this galaxy have a ring of bright blue stars? Beautiful island universe Messier 94 lies a mere 15 million light-years distant in the northern constellation of the Hunting Dogs (Canes Venatici). A popular target for Earth-based astronomers, the face-on spiral galaxy is about 30,000 light-years across, with spiral arms sweeping through the outskirts of its broad disk. But this Hubble Space Telescope field of view spans about 7,000 light-years across M94's central region. The featured close-up highlights the galaxy's compact, bright nucleus, prominent inner dust lanes, and the remarkable bluish ring of young massive stars. The ring stars are all likely less than 10 million years old, indicating that M94 is a starburst galaxy that is experiencing an epoch of rapid star formation from inspiraling gas. The circular ripple of blue stars is likely a wave propagating outward, having been triggered by the gravity and rotation of a oval matter distributions. Because M94 is relatively nearby, astronomers can better explore details of its starburst ring.

 

멋지고 아름다운 우주여행에 탑승해주셔서 감사합니다.

다음에도 멋진 장소로 모실 수 있도록 노력하겠습니다.
