아름답고 멋진 우주사진 2023년 12월 14일

2023년 12월 14일자 도착할 우주여행 장소는 사진에 나온 장소입니다.

여기는 Supernova Remnant Cassiopeia A 입니다. 

 

 

Massive stars in our Milky Way Galaxy live spectacular lives. Collapsing from vast cosmic clouds, their nuclear furnaces ignite and create heavy elements in their cores. After only a few million years for the most massive stars, the enriched material is blasted back into interstellar space where star formation can begin anew. The expanding debris cloud known as Cassiopeia A is an example of this final phase of the stellar life cycle. Light from the supernova explosion that created this remnant would have been first seen in planet Earth's sky about 350 years ago, although it took that light 11,000 years to reach us. This sharp NIRCam image from the James Webb Space Telescope shows the still hot filaments and knots in the supernova remnant. The whitish, smoke-like outer shell of the expanding blast wave is about 20 light-years across, while the bright speck near center is a neutron star, the incredibly dense, collapsed remains of the massive stellar core. Light echoes from the massive star's cataclysmic explosion are also identified in Webb's detailed image of supernova remnant Cassiopeia A. Tonight watch: The Geminids

 

멋지고 아름다운 우주여행에 탑승해주셔서 감사합니다.

다음에도 멋진 장소로 모실 수 있도록 노력하겠습니다.
