전세계의 모든 망원경들이 지근거리의 먼지를 가득 둘러쓴 은하에서 발생한 밝은 초신성을 쫓고 있다.
이 강력한 별의 폭발은 이달 초 관측되었다.

가까운 거리에 위치하며 멋진 사진 촬영대상이기도 한 센타우루스 A는 쌍안경으로도 볼 수 있는 은하이며 중심지역을 가로지르며 별빛을 흡수하는 먼지다발이 인상적인 은하이다.

사진의 센타우루스 A는 허블우주망원경이 촬영하여 축적하고 있는 데이터에 초신성  발견 이틀 후 지상에서 촬영한 초신성의 모습을 입힌 것이다.

 

SN2016adj로 등재되어 있는 이 초신성이 상단 우측 네모 사진에서 미리내에 속한 밝은 별 바로 옆에 십자선으로 표시되어 있다.
이 초신성은 현재 중심핵의 붕괴를 통해 발생하는 IIb 유형의 초신성으로 생각되고 있다.
이 초신성은 너무나 가까운 위치에서 발생했기 때문에, 그리고 은하의 먼지다발을 통해 그 모습이 목격되고 있기 때문에 큰 흥미를 끌고 있다.

이 초신성에 대한 현재와 향후 관측을 통해 무거운 별의 운명에 대해서, 그리고 지구에서 발견되는 몇몇 원소들이 어떻게 형성되었는지에 대해서 알 수 있게 될 것이다.

A Supernova through Galaxy Dust

Explanation: Telescopes around the world are tracking a bright supernova that occurred in a nearby dusty galaxy. The powerful stellar explosion was first noted earlier this month. The nearby galaxy is the photogenic Centaurus A, visible with binoculars and known for impressive filaments of light-absorbing dust that cross its center. Cen A is featured here in a high-resolution archival Hubble Space Telescope image, with an inset image featuring the supernova taken from the ground only two days after discovery. Designated SN2016adj, the supernova is highlighted with crosshairs in the inset, appearing just to the left of a bright foreground star in our Milky Way Galaxy. This supernova is currently thought to be of Type IIb, a stellar-core-collapse supernova, and is of high interest because it occurred so nearby and because it is being seen through a known dust filament. Current and future observations of this supernova may give us new clues about the fates of massive stars and how some elements found on our Earth were formed.
