[漢羅] 獅仔座三重奏

Tī 三月 ê 春分 kah 北半球春天 ê 暗頭仔，會當看著這个足紅 ê 星群。 In to̍h 是有名 ê 獅仔座三生仔。 這三个華麗 ê 星系，to̍h tī 這个特別 ê 獅仔座 內底，拄仔好 tī 仝一个天文視野內底會當看著。 To̍h 算是一般民眾用普通 ê 望遠鏡來 kā 看，in 嘛會使分出 NGC 3628（正爿），M66（倒爿面頂），kah M65（下跤）。 In 攏是較大 ê 捲螺仔星系，毋閣看起來有淡薄仔無仝。 因為 in ê 星系盤 tùi 咱 ê 視線方向來講，是敧無仝款 ê 方向。 NGC 3628 嘛叫做美國割包星系。 伊是一个足迷人 ê 側向星系，有一條塗粉烏帶 kā 伊蓬鬆蓬鬆 ê 星系盤切做兩爿。 M66 kah M65 ê 星系盤攏趨有夠，予人看會著 in ê 捲螺仔結構。 這三个星系 ê 引力交互作用有留一寡仔線索落來。 包括潮汐尾溜 kah 彎曲 無平 ê 星系盤，閣有 kā 捲螺仔手骨伸出來 ê M66。 這个華麗 ê 景色 tī 天頂有 1 度闊（兩粒月圓 ê 闊度）ê 範圍。 若是用三重奏 ê 估算距離 3000 萬光年來 kā 算，這幅圖有超過 50 萬光年闊。 毋免講，tī 遐彼粒足光 ê 前景星，是 tī 咱 ê 銀河內底。

[English] The Leo Trio

This popular group leaps into the early evening sky around the March equinox and the northern hemisphere spring. Famous as the Leo Triplet, the three magnificent galaxies found in the prominent constellation Leo gather here in one astronomical field of view. Crowd pleasers when imaged with even modest telescopes, they can be introduced individually as NGC 3628 (right), M66 (upper left), and M65 (bottom). All three are large spiral galaxies but tend to look dissimilar, because their galactic disks are tilted at different angles to our line of sight. NGC 3628, also known as the Hamburger Galaxy, is temptingly seen edge-on, with obscuring dust lanes cutting across its puffy galactic plane. The disks of M66 and M65 are both inclined enough to show off their spiral structure. Gravitational interactions between galaxies in the group have left telltale signs, including the tidal tails and warped, inflated disk of NGC 3628 and the drawn out spiral arms of M66. This gorgeous view of the region spans over 1 degree (two full moons) on the sky in a frame that covers over half a million light-years at the trio's estimated distance of 30 million light-years. Of course the spiky foreground stars lie well within our own Milky Way.
