[漢羅] 孤張感光 ê 仙女座星系

你會當看偌遠？ 離咱有 250 萬光年遠 ê 仙女座星系，是咱直接用目睭 to̍h 看會著 ê 上遠 ê 天體。 夜空內底其他 ê 住民，親像是恆星、星團、星雲，差不多幾若百抑是幾若千光年遠爾爾。 Tùi 太陽系來講 in 已經有夠遠矣，毋閣 in 猶 tī 咱 ê 銀河系 內底。 仙女座星系又閣叫做 M31，是 銀河外 ê 星系。 這張精心設計 ê 深空夜景，是 tī 葡萄牙南部一个老礦場，M31 to̍h tī 煙筒管 ê 頭殼頂。 這个影像是追蹤天景 ê 孤張感光，所以前景才會因為 kha-mé-lah ê 振動煞小可仔霧霧。 毋閣 仙女座星系看起來是有夠大。 這个星系較光 ê 中心區，一般來講用目睭是攏看有。 外沿 ê 捲螺仔手骨 to̍h 較暗，tī 天頂 ê 大細差不多有 4 粒月圓遐爾闊。 是講時間差不多賰 50 億年左右爾爾，仙女座星系 kah 銀河系 to̍h 會合併。 到時仙女座星系內底 ê 恆星 to̍h 會湠到咱 規个夜空。

[English] Andromdeda in a Single Shot

How far can you see? The Andromeda Galaxy, 2.5 million light years away, is the most distant object easily seen by the unaided eye. Other denizens of the night sky, like stars, clusters, and nebulae, are typically hundreds to thousands of light-years distant. That's far beyond the Solar System but well within our own Milky Way Galaxy. Also known as M31, the external galaxy poses directly above a chimney in this well-planned deep night skyscape from an old mine in southern Portugal. The image was captured in a single exposure tracking the sky, so the foreground is slightly blurred by the camera's motion while Andromeda itself looms large. The galaxy's brighter central region, normally all that's visible to the naked-eye, can be seen extending to spiral arms with fainter outer reaches spanning over 4 full moons across the sky. Of course in only 5 billion years or so, the stars of Andromeda could span the entire night sky as the Andromeda Galaxy merges with the Milky Way.
