NASA 오늘의 사진 – 하늘의 열쇠구멍

옛날에 올라온 NASA의 재미있는 사진입니다.

1999.11에 허블 우주망원경으로 찍은 오리온자리 근처의 반사성운인 NGC1999라는 성운이라고 합니다.
재미있게 생겼죠? 꼭 열쇠구멍같은….

전 이런 사진을 볼 때마다 옛날에 봤던 어떤 사진을 떠올립니다.
망원경으로 천국의 사진이 찍혔다는 사이비종교의 전단물의 그 사진….
하나님께서 이미 천국을 준비해 두고 계신다나요???

그 전단지를 돌린 사람들은 알까요?
만약 그 사진이 진짜라고 하더라도 그 사진에 찍힌 건물들 하나하나의 크기가 태양계보다 훨씬 더 클거라는 사실…
따라서 거기에 살려면 사람보다 수천억[footnote]계산해 본 것이 아니고 그냥 크다는 의미에서…^^[/footnote] 배는 더 큰 사람이어야 한다는 것을…..

Just weeks after NASA astronauts repaired the Hubble Space Telescope in December 1999, the Hubble Heritage Project snapped this picture of NGC 1999, a reflection nebula in the constellation Orion.

Like fog around a street lamp, a reflection nebula shines only because the light from an embedded source illuminates its dust; the nebula does not emit any visible light of its own. The nebula is famous in astronomical history because the first Herbig-Haro object was discovered immediately adjacent to it (it lies just outside the new Hubble image). Herbig-Haro objects are now known to be jets of gas ejected from very young stars.

The nebula is illuminated by a bright, recently formed star, visible just to the left of center. This star is cataloged as V380 Orionis, and its white color is due to its high surface temperature of about 10,000 degrees Celsius, nearly twice that of our own sun. Its mass is estimated to be 3.5 times that of the sun. The star is so young that it is still surrounded by a cloud of material left over from its formation, here seen as the NGC 1999 reflection nebula.

NGC 1999 shows a remarkable jet-black cloud near its center, located just to the right and lower right of the bright star. This dark cloud is an example of a “Bok globule,” named after the late University of Arizona astronomer Bart Bok. The globule is a cold cloud of gas, molecules and cosmic dust, which is so dense it blocks all of the light behind it. The globule is seen silhouetted against the reflection nebula illuminated by V380 Orionis. Astronomers believe that new stars may be forming inside Bok globules, through the contraction of the dust and molecular gas under their own gravity.
