오늘의 우주 사진 (2023-06-01)

최근 NASA에서 우주 모습을 알려줬는데요 과연 어떻게 보여질지 기대가 됩니다
그러면 지금부터 이미지를 살펴보겠습니다

 

이 사진의 이름은 Recycling Cassiopeia A 인데요 국제기구인 NASA에서도 공식 자료를 확인해보도록 하겠습니다

 

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 a few million years, 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 explosion which created this supernova remnant would have been first seen in planet Earth's sky about 350 years ago, although it took that light about 11,000 years to reach us. This false-color image, composed of X-ray and optical image data from the Chandra X-ray Observatory and Hubble Space Telescope, shows the still hot filaments and knots in the remnant. It spans about 30 light-years at the estimated distance of Cassiopeia A. High-energy X-ray emission from specific elements has been color coded, silicon in red, sulfur in yellow, calcium in green and iron in purple, to help astronomers explore the recycling of our galaxy's star stuff. Still expanding, the outer blast wave is seen in blue hues. The bright speck near the center is a neutron star, the incredibly dense, collapsed remains of the massive stellar core.

 

이번에도 광대한 우주크기에 인간이 얼마나 작은지 확인하게 되는 사건입니다
그러면 다음시간에 더 좋은 정보들을 들고 오도록 하겠습니다 행복한 지구여행 되시길 바랍니다
