[漢羅] 捲螺仔星系 NGC 2841

捲螺仔星系 NGC 2841 離咱有 4600 萬光年遠，會當 tī 北方星座 大熊座 ê 方向揣著。 這張 深空景色 內底 ê 美麗 島宇宙，是 kā 2021 年 11 月 到 2022 年 1 月 之間，32 暗 好天 ê 時陣 翕著 ê 相片，疊做一張 ê。 相片內底有明顯 ê 黃色 星系核、星系盤、佮 外圍較暗 ê 區域。 毋閣塗粉帶、較細區 ê 恆星形成區、佮 少年星系團，to̍h 藏 tī 一節一節、捲 絚絚 ê 捲螺仔 手骨 內底。 若是佮其他 ê 捲螺仔星系 相比，in ê 捲螺仔手骨攏較大支，嘛有較大範圍 ê 恆星形成區。 NGC 2841 ê 直徑超過 15 萬光年闊，比咱 ê 銀河系閣較大。 伊 ê X-光影像 kā 咱講，星系風 kah 恆星爆炸產生 ê 高溫氣體煙，攏走入去 NGC 2841 外圍 ê 星系暈 內底矣！

[English] Spiral Galaxy NGC 2841

A mere 46 million light-years distant, spiral galaxy NGC 2841 can be found in the northern constellation of Ursa Major. This deep view of the gorgeous island universe was captured during 32 clear nights in November, December 2021 and January 2022. It shows off a striking yellow nucleus, galactic disk, and faint outer regions. Dust lanes, small star-forming regions, and young star clusters are embedded in the patchy, tightly wound spiral arms. In contrast, many other spirals exhibit grand, sweeping arms with large star-forming regions. NGC 2841 has a diameter of over 150,000 light-years, even larger than our own Milky Way. X-ray images suggest that resulting winds and stellar explosions create plumes of hot gas extending into a halo around NGC 2841.
