[漢羅] 厝邊 ê 大質量捲螺仔星系 NGC 2841
NGC 2841 是一个咱熟似 ê 大質量星系。伊是一个佇北爿 ê 大熊座 內底,干焦 4600 萬光年遠 ê 捲螺仔星系。這个遮爾清楚 koh 美麗 ê 宇宙島,有一个足明顯 ê 黃色星系核 kah 星系盤。佇一節一節、絞 ân ê 捲螺仔 手骨內底,有塗粉帶、有粉紅仔斑 ê 恆星形成區、閣有少年 ê 藍色星團。毋閣,大部份 ê 捲螺仔星系 sī 有較分明 ê 手骨 kah 較大 ê 恆星形成區。NGC 2841 ê 直徑超過 15 萬 光年 闊,比 咱 ê 銀河閣較大。這張組合影像是 kā 2.4 公尺闊 ê 踅地衛星 哈伯太空望遠鏡 kah 8.2 公尺闊 ê 地面望遠鏡 Subaru 望遠鏡,合併感光而成 ê。Ùi X 光 ê 影像推測,恆星風 kah 恆星爆炸產生噴懸 ê 高溫氣體,湠到 NGC 2841 ê 銀暈。

[English] Massive Nearby Spiral Galaxy NGC 2841
It is one of the more massive galaxies known.A mere 46 million light-years distant, spiral galaxy NGC 2841 can be found in the northern constellation of Ursa Major .This sharp view of the gorgeous island universe shows off a striking yellow nucleus and galactic disk.Dust lanes, small, pink star-forming regions, and young blue star clustersare embedded in the patchy, tightly wound spiral arms. In contrast , many other spiralsexhibit 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.The featured composite image merges exposures from the orbiting 2.4-meter Hubble Space Telescope and the ground-based 8.2-meter Subaru Telescope . X-ray images suggest that resulting winds and stellar explosions createplumes of hot gas extending into a halo around NGC 2841 .
