[漢羅] 半人馬座 A:特殊 ê 天星島
星系是足媠--ê。 星系 內底,干焦引力就會當 kā 足濟恆星、塗粉、星際氣體、恆星殘骸、kah 烏暗物質攏搝做伙。 這張相片 是一个差不多 1200 萬光年遠 ê 星系,伊是天頂第五光 ê 星系,編號是 NGC 5128,毋過伊較 hŏng 會記 ê 名是 半人馬座 A。 半人馬座 A 這个彎曲 ê 形體,是一个 長株圓星系 kah 一个 捲螺仔星系 合併 ê 結果。 半人馬座 A 內底有一个 活跳星系核,中心是一粒 超大質量烏洞。 這粒烏洞 ê 質量差不多是咱太陽 ê 5500 萬 倍左右。 中心這粒烏洞噴出速度足緊 ê 噴射流,tī 電波 波段 kah X 光 波段攏看會著。 噴射流 ê 雲絲是紅色--ê,就 tī 相片倒爿頂懸遐。 Ùi 事件視界望遠鏡 提著 ê 新--ê 觀測資料 表示講,噴射流 ê 四箍圍仔是有較光。 毋過是按怎會按呢,科學家 這馬猶毋是蓋了解,所以這就變做一个足衝 ê 研究主題矣。

[English] Centaurus A: A Peculiar Island of Stars
Galaxies are fascinating. In galaxies, gravity alone holds together massive collections of stars, dust, interstellar gas, stellar remnants and dark matter. Pictured, located at a distance of about 12 million light years, lies the fifth brightest galaxy on the sky cataloged as NGC 5128, but better known as Centaurus A. The warped shape of Cen A is the result of a merger between an elliptical and a spiral galaxy. Cen A has an active galactic nucleus that harbors a supermassive black hole in its center that weighs in at about 55 million times more massive than our Sun. This central black hole ejects a fast jet visible in both radio and X-ray light. Filaments of the jet pointing are visible in red in the upper left. New observations by the Event Horizon Telescope have revealed a brightening of the jet only towards its edges -- but for reasons that are currently unknown and an active topic of research.
