[漢羅] NGC 3628 ê 肖像

佇 NGC 3628 這張清楚 ê 望遠鏡影像內底，咱看會著膨獅獅 ê 星系盤，去予烏暗 ê 塗粉帶破做兩爿。 這張華麗 ê 側向捲螺仔星系 肖像，予一寡天文學家 想著，伊閣有一个較有名 ê 偏名，叫做美國割包星系。 NGC 3628 下跤閣有一个較細 ê 星系，應該是伊 ê 衛星星系。 伊閣有一條足暗，毋閣伸足長 ê 潮汐尾溜。 這條搝長 ê 尾溜差不多是 30 萬光年長，超過這幅圖倒爿頂懸 ê 範圍。 NGC 3628 佮 伊兩个 厝邊星系，大捲螺仔星系 M65 佮 M66，去 hŏng 鬥做一組，叫做 獅仔座三生仔，in 三个是佇仝一个本地宇宙 ê 環境內。 這三个厝邊星系 ê 重力交互作用，應該就是造成潮汐尾溜 ê 原因。 而且這嘛是造成捲螺仔星系盤面頂有大片 ê 爍光，造成星系盤扭曲 ê 原因。 這个迷人 ê 島宇宙 就佇北天 ê 春季星座 獅仔座 內底。 伊差不多有 10 萬光年闊，離咱有 3500 萬光年遠。

[English] Portrait of NGC 3628

Sharp telescopic views of NGC 3628 show a puffy galactic disk divided by dark dust lanes. Of course, this portrait of the magnificent, edge-on spiral galaxy puts some astronomers in mind of its popular moniker, the Hamburger Galaxy. It also reveals a small galaxy nearby (below), likely a satellite of NGC 3628, and a very faint but extensive tidal tail. The drawn out tail stretches for about 300,000 light-years, even beyond the upper left edge of the frame. NGC 3628 shares its neighborhood in the local universe with two other large spirals M65 and M66 in a grouping otherwise known as the Leo Triplet. Gravitational interactions with its cosmic neighbors are likely responsible for creating the tidal tail, as well as the extended flare and warp of this spiral's disk. The tantalizing island universe itself is about 100,000 light-years across and 35 million light-years away in the northern springtime constellation Leo.
