[漢羅] NGC 7331 ê 特寫

大閣媠 ê 捲螺仔星系 NGC 7331 定定去 hŏng 提來 kah 咱 ê 銀河 做比較。 NGC 7331 離咱差不多有 5000 萬光年遠，就 chhāi tī 北天星座 飛馬座 遐。 伊早期去 hŏng 認為是一个 捲螺仔星雲，雖罔講伊嘛足光--ê，毋閣伊煞無去予編入去 18 世紀彼个 有名 ê Charles Messier 星表內底。 因為這个星系盤 趨 tùi 咱 ê 視線方向，所以咱若是用望遠鏡長時間感光，翕出來 ê 影像定定會 hŏng 感受著宇宙是有偌深。 這張 Hubble 太空望遠鏡 ê 特寫相片，有 4 萬光年遐爾闊。 這个星系實在是有夠壯觀 ê 啦！ 伊 ê 捲螺仔手骨內底，有烏暗閘光 ê 塗粉帶、藍光閃閃 ê 大質量少年星團、kah 紅光爍爍 ê 活跳恆星形成區。 星系中央發黃光 ê 區域，有足濟較老、較冷 ê 恆星。 捲螺仔星系 NGC 7331 kah 咱 ê 銀河仝款，tī 伊 ê 中心有一粒超大質量烏洞。

[English] NGC 7331 Close Up

Big, beautiful spiral galaxy NGC 7331 is often touted as an analog to our own Milky Way. About 50 million light-years distant in the northern constellation Pegasus, NGC 7331 was recognized early on as a spiral nebula and is actually one of the brighter galaxies not included in Charles Messier's famous 18th century catalog. Since the galaxy's disk is inclined to our line-of-sight, long telescopic exposures often result in an image that evokes a strong sense of depth. This Hubble Space Telescope close-up spans some 40,000 light-years. The galaxy's magnificent spiral arms feature dark obscuring dust lanes, bright bluish clusters of massive young stars, and the telltale reddish glow of active star forming regions. The bright yellowish central regions harbor populations of older, cooler stars. Like the Milky Way, a supermassive black hole lies at the core of spiral galaxy NGC 7331.
