[漢羅] 仙女座星系 ê 紫外光影像

仙女座星系 tī 紫外光看起來是啥款？ 伊 ê 星系中心主要是少年藍色恆星 leh 踅。 仙女座星系 離咱干焦 250 萬光年爾爾，伊嘛叫做 M31，伊真正是咱厝邊 ê大星系。 這个星系有 23 萬光年 闊。 這張華麗 ê 影像，是 NASA ê 星系演化探索計畫 (GALEX) 衛星太空望遠鏡 tī 2003 年翕 ê。 這是 捲螺仔星系 ê 紫外光影像。 仙女座 ê 捲螺仔手骨 tī 可見光影像 足明顯 ê。 毋閣伊 tī 紫外光看起來較成是一个環。 這个環內底有足強 ê 恆星形成活動。 這應該是仙女座星系 kah 伊較細粒 ê 厝邊星系，長株圓星系 M32，tī 2 億年前相碰 ê 證據。 仙女座星系 kah 咱 ê 銀河系 攏是 本底星系團 內底上大質量 ê 成員。 閣幾若十億年了後，in 可能 to̍h 會相碰。 彼 ê 時陣，咱 ê 太陽 大氣會脹大 到 kā 地球食去。

[English] The Andromeda Galaxy in Ultraviolet

What does the Andromeda galaxy look like in ultraviolet light? Young blue stars circling the galactic center dominate. A mere 2.5 million light-years away, the Andromeda Galaxy, also known as M31, really is just next door as large galaxies go. Spanning about 230,000 light-years, it took 11 different image fields from NASA’s Galaxy Evolution Explorer (GALEX) satellite telescope to produce this gorgeous portrait of the spiral galaxy in ultraviolet light in 2003. While its spiral arms stand out in visible light images, Andromeda’s arms look more like rings in ultraviolet. The rings are sites of intense star formation and have been interpreted as evidence that Andromeda collided with its smaller neighboring elliptical galaxy M32 more than 200 million years ago. The Andromeda galaxy and our own comparable Milky Way galaxy are the most massive members of the Local Group of galaxies and are projected to collide in several billion years – perhaps around the time that our Sun’s atmosphere will expand to engulf the Earth.
