[漢羅] 捲螺仔星系 NGC 2841

咱會當 tī 北天 ê 大熊座 方向揣著捲螺仔星系 NGC 2841，伊是 夜空 中算袂䆀揣 ê 天體，離咱才 4600 萬光年遠爾爾。 這張 清楚相片中央 有一个華麗 ê 島宇宙。 前景 ê 光針，其實是銀河系內底 ê 恆星，kah 背景遙遠 ê 星系，做伙出現 tī 仝一个望遠鏡景色內底。 NGC 2841 有一个光 iàⁿ-iàⁿ ê 星系核，坦敧 ê 星系盤，kah 暗淡 ê 外部區域。 星系內底 花貓貓、踅 絚絚 ê 捲螺仔手骨 頂懸，有塗粉帶、較細區 ê 恆星形成區、kah 少年星團。 相對來講，大部份其他捲螺仔星系 ê 捲螺仔手骨攏較闊、較散，嘛有較大區 ê 恆星形成區。 NGC 2841 ê 直徑超過 15 萬 光年，比咱銀河系閣較大。 X 光影像 表示講，巨星 ê 大尺度噴流 kah 恆星爆炸產生 ê 高溫氣體雲煙，會湠到 NGC 2841 ê 星系暈去。

[English] Spiral Galaxy NGC 2841

A mere 46 million light-years distant, spiral galaxy NGC 2841 can be found in planet Earth's night sky toward the northern constellation of Ursa Major. This sharp image centered on the gorgeous island universe also captures spiky foreground Milky Way stars and more distant background galaxies within the same telescopic field of view. It shows off the bright nucleus of NGC 2841, along with its inclined galactic disk, and faint outer regions. Dust lanes, small star-forming regions, and young star clusters are embedded in the galaxy's patchy, tightly wound spiral arms. In contrast, many other spirals exhibit broader, sweeping arms with large star-forming regions. NGC 2841 has a diameter of over 150,000 light-years, making it even larger than our own Milky Way. X-ray images suggest that extreme outflows from giant stars and stellar explosions create plumes of hot gas extending into a halo around NGC 2841.
