Water's Early Journey

우주 어디에선가 새로이 태어나는 태양계의 모습을 보여주고 있습니다.

 

우리가 살고 있는 태양계 가까운 곳에서 태어나서

 

지구와 같은 살기좋은 행성도 생성이 되면 참으로 고맙겠죠.

NASA's Spitzer Space Telescope observed a fledgling solar system, like the one depicted in this artist's concept, and discovered deep within it enough water vapor to fill the oceans on Earth five times. This water vapor starts out in the form of ice in a cloudy cocoon (not pictured) that surrounds the embryonic star, called NGC 1333-IRAS 4B (buried in center of image). Material from the cocoon, including ice, falls toward the center of the cloud. The ice then smacks down onto a dusty pre-planetary disk circling the stellar embryo (doughnut-shaped cloud) and vaporizes. Eventually, this water might make its way into developing planets.
