오늘의 우주 사진 (2023-05-31)

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

 

이 사진의 이름은 Simulation: A Disk Galaxy Forms 인데요 국제기구인 NASA에서도 공식 자료를 확인해보도록 하겠습니다

 

How did we get here? We know that we live on a planet orbiting a star orbiting a galaxy, but how did all of this form? Since our universe moves too slowly to watch, faster-moving computer simulations are created to help find out. Specifically, this featured video from the IllustrisTNG collaboration tracks gas from the early universe (redshift 12) until today (redshift 0). As the simulation begins, ambient gas falls into and accumulates in a region of relatively high gravity. After a few billion years, a well-defined center materializes from a strange and fascinating cosmic dance. Gas blobs -- some representing small satellite galaxies -- continue to fall into and become absorbed by the rotating galaxy as the present epoch is reached and the video ends. For the Milky Way Galaxy, however, big mergers may not be over -- recent evidence indicates that our large spiral disk Galaxy will collide and coalesce with the slightly larger Andromeda spiral disk galaxy in the next few billion years.

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