西拉與卡律布迪斯之間:雙重宇宙發現
Between Scylla and Charybdis: A Double Cosmic Discovery

發表日期:2025-06-09
你能認出這個天體嗎? 可能不能--因為這是一張發現圖片。 大質量恆星在其核心中形成重元素,幾百萬年後,在強大的超新星爆炸中結束自己的生命。這些殘餘物冷卻得相對較快並逐漸消失,因此很難被探測到。 為了發現這些微弱的、以前未知的超新星殘餘物,一組專門的業餘天體攝影師透過巡天觀測尋找可能的超新星殘餘物候選者。 結果:首次拍攝到了超新星殘餘 G 115 . 5 + 9 . 1 (發現者將其命名為 Scylla)的影像,它在神話傳說中的埃提俄比亞王的星座中發出微弱的光芒:仙王座。 殘餘物中氫原子的發射顯示為紅色,氧氣的微弱發射顯示為藍色。 令人驚訝的是,右上方還潛伏著另一個發現:一個暗淡的、以前未知的候選行星狀星雲。按照神話傳統,它被命名為卡律布迪斯(賽 2 )--這與古希臘荷馬史詩《奧德賽》中的 "被困在希拉和卡律布迪斯之間 "的說法相吻合。
原文:Can you identify this celestial object? Likely not — because this is a discovery image. Massive stars forge heavy elements in their cores and, after a few million years, end their lives in powerful supernova explosions. These remnants cool relatively quickly and fade, making them difficult to detect. To uncover such faint, previously unknown supernova remnants, a dedicated group of amateur astrophotographers searched through sky surveys for possible supernova remnant candidates. The result: the first-ever image of supernova remnant G115.5+9.1 — named Scylla by its discoverers—glowing faintly in the constellation of the mythological King of Aethiopia: Cepheus. Emission from hydrogen atoms in the remnant is shown in red, and faint emission from oxygen is shown in hues of blue. Surprisingly, another discovery lurked to the upper right: a faint, previously unknown planetary nebula candidate. In keeping with mythological tradition, it was named Charybdis (Sai 2) — a nod to the ancient Greek expression "caught between Scylla and Charybdis" from Homer’s Odyssey.
