[漢羅] 捲螺仔星系 M74：較清楚 ê 版本

美麗 ê 捲螺仔星系 Messir 74 (嘛叫做 NGC 628) 就 chhāi tī 雙魚座 ê 方向，離咱有 3200 萬光年遠。 M74 有兩支足大支 ê 捲螺仔手骨，這个島宇宙差不多有 1000 億粒恆星 tī 內底。 長期以來，攏因為伊 ê 宏偉結構，煞去予天文學家 kā 伊當做是捲螺仔星系 ê 模範。 這張是最近 ùi James Webb 太空望遠鏡 ê 公開觀測資料 處理 ê 影像，M74 ê 中央區清楚甲予人掣一趒。 這張彩色 ê 合成影像是 ùi Webb 太空望遠鏡 ê 兩个儀器 NIRcam kah MIRI 來--ê。 In 是 近紅外線 kah 中紅外線波段 ê kha-mé-lah。 Tī 這个有宏偉結構 ê 捲螺仔星系影像內底，看會著較冷 ê 恆星 kah 塗粉結構，這攏是以前 ê 太空望遠鏡 看袂著--ê。

[English] Spiral Galaxy M74: A Sharper View

Beautiful spiral galaxy Messier 74 (also known as NGC 628) lies some 32 million light-years away toward the constellation Pisces. An island universe of about 100 billion stars with two prominent spiral arms, M74 has long been admired by astronomers as a perfect example of a grand-design spiral galaxy. M74's central region is brought into a stunning, sharp focus in this recently processed image using publicly available data from the James Webb Space Telescope. The colorized combination of image data sets is from two of Webb's instruments NIRcam and MIRI, operating at near- and mid-infrared wavelengths. It reveals cooler stars and dusty structures in the grand-design spiral galaxy only hinted at in previous space-based views.
