[漢羅] 探索蝶仔鬚星系

Tī 南方 ê 烏鴉座 方向，離咱差不多 6000 萬光年遠 ê 所在，有兩个大星系當咧相挵。 這兩个星系編做 NGC 4038 kah NGC 4039。 自 in 兩个相挵到今，這个災難已經幾若億年矣。 毋閣 in 內底 ê 恆星，無啥會相挵。 星系 ê 大型 分子氣體塗粉雲，嘛定定會 tī 宇宙殘骸 ê 中心附近，驅動 激烈 ê 恆星形成活動。 這个壯麗 ê 景色有 50 萬光年闊。 咱看會著新 ê 星團 kah 去予 引潮力 ùi 事故現場擲到足遠 ê 物質。 這張 遮爾清楚 ê 地面望遠鏡影像，是 kā 2012 年到 2021 年之間翕 ê 相片，揀 88 點鐘久 ê 感光時間 累積--起來 ê 結果。 視野內底閣有較暗 ê 潮汐尾溜 kah 較遠 ê 背景星系。 這个伸長 ê 弧形結構，予這兩个星系看--起來敢若是一對，這規組 to̍h 編做 Arp 244。 咱一般攏 kā 叫做是：蝶仔鬚星系。

[English] Exploring the Antennae

Some 60 million light-years away in the southerly constellation Corvus, two large galaxies are colliding. Stars in the two galaxies, cataloged as NGC 4038 and NGC 4039, very rarely collide in the course of the ponderous cataclysm that lasts for hundreds of millions of years. But the galaxies' large clouds of molecular gas and dust often do, triggering furious episodes of star formation near the center of the cosmic wreckage. Spanning over 500 thousand light-years, this stunning view also reveals new star clusters and matter flung far from the scene of the accident by gravitational tidal forces. The remarkably sharp ground-based image, an accumulation of 88 hours of exposure captured during 2012-2021, follows the faint tidal tails and distant background galaxies in the field of view. The suggestive overall visual appearance of the extended arcing structures gives the galaxy pair, also known as Arp 244, its popular name - The Antennae.
