[漢羅] 咱附近 ê 捲螺仔星系 NGC 4945

這是 大捲螺仔星系 NGC 4945 ê 特寫,這个宇宙星系是一个 側向 星系,kah 咱 ê 銀河系 是差不多大。 Tī 這張彩色 ê 望遠鏡影像內底,咱會當清楚看著 NGC 4945 有厚塗粉 ê 星系盤,少年 ê 藍色星系團,kah 粉紅仔色 ê 恆星形成區。 NGC 4945 tī 南天 ê 星座 半人馬座 ê 方向,離咱差不多 1300 萬 光年遠 ê 所在,按呢差不多是咱到 仙女座星系 距離 ê 6 倍遠。 仙女座星系是離咱銀河系上近 ê 星系。 咱若是用光學望遠鏡來 kā 看,NGC 4945 ê 星系中心區實在是看無。 毋閣 X-光 kah 紅外線 觀測表示,伊 ê 核心區 有 足明顯 ê 高能發射 kah 恆星形成活動。 這粒藏 tī 星系中心、活動力足強 ê 核心,予這个華麗 ê 島宇宙成做一个 Seyfert 星系。 Seyfert 星系 ê 中心,其實有一粒 超大質量烏洞。

[English] Nearby Spiral Galaxy NGC 4945

Large spiral galaxy NGC 4945 is seen nearly edge-on in this cosmic galaxy close-up. It's almost the size of our Milky Way Galaxy. NGC 4945's own dusty disk, young blue star clusters, and pink star forming regions standout in the colorful telescopic frame. About 13 million light-years distant toward the expansive southern constellation Centaurus, NGC 4945 is only about six times farther away than Andromeda, the nearest large spiral galaxy to the Milky Way. Though this galaxy's central region is largely hidden from view for optical telescopes, X-ray and infrared observations indicate significant high energy emission and star formation in the core of NGC 4945. Its obscured but active nucleus qualifies the gorgeous island universe as a Seyfert galaxy and home to a central supermassive black hole.
