[漢羅] 真特殊 ê 半人馬座 A ê 噴流

這个 ùi 半人馬座 A 噴出來 ê 噴流有百外萬光年長。這个 ùi 捲螺仔星系中央 ê 超大烏洞噴出來 ê 電漿 噴流，kā 這張影像 ê 半人馬座 A 照予光。是講，烏洞 是按怎 kā 食入來 ê 物件噴出去，到今逐家猶是捎攏無。噴流 離開星系了後，to̍h 歕出一个足大 ê 電波氣泡，差不多會發光幾仔百萬年遐爾長。伊若是去予噴過 ê 氣體激發，這个電波氣泡 to̍h 會當佇 十億年了後 閣再繼續發光。X 光 佇 這張組合影像 是藍色 ê，微波 光 是柑仔色 ê。佇這个 電波 噴流 ê 源頭，看會著 噴流上中央 1 光年闊 ê 詳細狀況。

[English]  Jets from Unusual Galaxy Centaurus A

The jets emanating from Centaurus A are over a million light years long. These jets of streaming plasma, expelled by a giant black hole in the center of this spiral galaxy, light up this composite image of Cen A. Exactly how the central black hole expels infalling matter remains unknown. After clearing the galaxy, however, the jets inflate large radio bubbles that likely glow for millions of years. If energized by a passing gas cloud, the radio bubbles can even light up again after billions of years. X-ray light is depicted in the featured composite image in blue, while microwave light is colored orange. The base of the jet in radio light shows details of the innermost light year of the central jet.
