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.

🌌 近日，全球的天文望遠鏡都在追蹤一顆明亮的超新星，這次的爆炸現象發生在一個附近的多塵星系。這場強大的恆星爆炸於本月初首次被發現，該星系乃是攝政座A（Centaurus A），用雙筒望遠鏡就能看見，並以其壯觀的吸光塵埃光絲而聞名。💫
在這裡展示的是一張高解析度的哈勃太空望遠鏡存檔圖像，並附上了在發現後僅僅兩天拍攝的地面影像，超新星SN2016adj被十字準星標示出來，位於我們銀河系的一顆明亮前景恆星的左側。✨
目前，這顆超新星被認為是IIb型超新星，它是恆星核心崩潰而形成的，因為它的近距離以及觀測到的已知塵埃光絲，使得這次的觀測特別重要。對於這顆超新星的當前及未來觀測可能會為我們提供有關大質量恆星命運的新線索，並揭示一些存在於地球上的元素是如何形成的。🌍🔭
