[漢羅] NGC 3628 ê 肖像

這張清楚 ê NGC 3628 望遠鏡景色內底，有一个蓬鬆蓬鬆 ê 星系盤，中央去予烏暗 ê 塗粉帶切做兩爿。 是講這幅雄偉 ê 側向捲螺仔星系 肖像，予一寡天文學家 想著 伊閣有一个流行 ê 偏名，號做美國割包星系。 NGC 3628 下底附近有一个較細 ê 星系，應該是伊 ê 衛星星系。 伊閣有一條足暗毋過搝甲足長 ê 潮汐尾溜。 這條搝甲長長 ê 尾溜有 30 萬光年長，超過這幅圖倒爿 ê 範圍。 Tī 本地宇宙內底，NGC 3628 kah 伊厝邊兩个大型捲螺仔星系 M65 kah M66 是一組--ê，in 就叫做 獅仔座三生仔。 發生 tī 宇宙厝邊之間 ê 重力 交互作用，可能是製造潮汐尾溜 ê 原因，嘛是造成捲螺仔星系盤 噴出物質 kah 變形 ê 原因。 這个美麗 ê 島宇宙 差不多有 10 萬光年闊，kah 咱 ê 距離有 3500 萬光年遠。 伊就 tī 北方 ê 春季星座，獅仔座遐。

[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 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.
