[漢羅] Arp 93：宇宙級 ê 攬牢牢

這張清楚 ê 望遠鏡視野中央有兩个大型星系合併，產生這款 宇宙級 ê 攬牢牢。 這組交互作用系統 去 hŏng 編做 Arp 93，伊就 tī 寶瓶座 方向 2 億光年遠 ê 所在。 這兩粒星系分別是 NGC 7285 (正爿彼个) kah NGC 7284 (倒爿彼个)。 兩粒光爍爍 ê 星系核 距離猶差 2 萬光年，毋過 in 之間 因為 引力交互作用 產生 ê 大片 潮汐流，是伸 tùi 影像下底 20 萬光年遠 ê 所在去。 交互作用星系看起來攏 足特別–ê，毋過咱這馬已經知影 in tī 宇宙內底其實是足四常 ê 天體。 實際上，咱兜附近嘛有。大型捲螺仔星系 仙女座星系，就當 leh 倚近咱 ê 銀河。 Arp 93 真有可能就是 咱 kah 仙女座星系 tī 未來 變做 宇宙級攬牢牢 ê 結果。

[English] Arp 93: A Cosmic Embrace

Locked in a cosmic embrace, two large galaxies are merging at the center of this sharp telescopic field of view. The interacting system cataloged as Arp 93 is some 200 million light-years distant toward the constellation Aquarius in planet Earth’s sky. Individually the galaxies are identified as NGC 7285 (right) and NGC 7284. Their bright cores are still separated by about 20,000 light-years or so, but a massive tidal stream, a result of their ongoing gravitational interaction, extends over 200,000 light-years toward the bottom of the frame. Interacting galaxies do look peculiar, but are now understood to be common in the Universe. In fact, closer to home, the large spiral Andromeda Galaxy is known to be approaching the Milky Way. Arp 93 may well present an analog of their distant future cosmic embrace.
