[漢羅] NGC 1097：有超新星 ê 捲螺仔星系

這个捲螺仔星系下面彼支捲螺仔手骨是發生啥物代誌？ 是出現一粒 超新星 啦！ 頂個月，阿拉伯聯合大公國 ê Al-Khatim 天文台 發現一粒 超新星 SN 2023rve。 紲落來閣 發現 伊 ê 特性 kah 大質量恆星死亡爆炸 ê 情形仝款，表示講伊嘛有可能留一粒 烏洞 tī 遐。 捲螺仔星系 NGC 1097 是一个 tī 咱附近 ê 星系，才 4500 萬 光年 遠爾爾，用細台望遠鏡就會使 tī 南天 ê 天爐座 方向看著伊。 這个星系會有名，毋但是因為伊有 足媠 ê 捲螺仔手骨，嘛是因為伊有 暗淡 ê 噴射流。 這个噴射流 和 伊 tī 古早時代 kah 其他星系相挵 留落來 ê 恆星流 有對同。 Kah 伊相挵 ê 星系，可能就是倒爿下跤 彼个 tī 捲螺仔手骨之間 ê 細粒星系。 這張影像 是靠 兩張差幾若個月 ê 相片 相疊比較，才標出這粒新發現 ê 超新星。 Tī 厝邊星系 揣超新星 是一項足重要 ê 工課，因為這會當決定咱 規个宇宙 ê 尺度 kah 脹大速度。 這是一个目前猶 足緊張、猶有 足濟爭論 ê 研究主題。

[English] NGC 1097: Spiral Galaxy with Supernova

What's happening in the lower arm of this spiral galaxy? A supernova. Last month, supernova SN 2023rve was discovered with UAE's Al-Khatim Observatory and later found to be consistent with the death explosion of a massive star, possibly leaving behind a black hole. Spiral galaxy NGC 1097 is a relatively close 45 million light years away and visible with a small telescope toward the southern constellation of the Furnace (Fornax). The galaxy is notable not only for its picturesque spiral arms, but also for faint jets consistent with ancient star streams left over from a galactic collision -- possibly with the small galaxy seen between its arms on the lower left. The featured image highlights the new supernova by blinking between two exposures taken several months apart. Finding supernovas in nearby galaxies can be important in determining the scale and expansion rate of our entire universe -- a topic currently of unexpected tension and much debate.
