[漢羅] 脹大 ê 毛蟹星雲

你 ê 目睭敢有好甲會當看著毛蟹星雲咧脹大？ 毛蟹星雲 ê 編號是 M1，伊是彼个有名 ê Charles Messier's 星表 頭一个天體。 這个星表內底 ê 天體，無一粒是彗星。 實際上，咱這馬知影 毛蟹星雲 是一个 超新星殘骸，是懸質量恆星爆炸了後產生 ê 脹大星雲內底 ê 雲屑仔。 這个 激烈出世 ê 毛蟹星雲，tī 1054 年 ê 時陣有 去予天文學家觀測著。 這个星雲這馬差不多有 10 光年 闊，毋過伊猶閣繼續咧 脹大。 這个脹大 ê 速度，一秒鐘有超過 1000 公里。 過去這 10 冬 ê 脹大狀況，就紀錄 tī 這支 予人讚嘆 ê 縮時攝影影片 內底。 Ùi 2008 年 到 2022 年之間，澳洲 ê 遙控天文台 逐年攏用 仝一台望遠鏡、仝一台 kha-mé-lah tùi 這个天體翕一張相片。 咱會當 tī 這張處理過--ê 清楚影像 看著 踅 中心彼粒 自旋速度足緊 ê 脈動星 邊仔 ê 動態高能 發射光。 毛蟹星雲 離咱有 6500 光年遠，就 tī 牛犅星座，金牛座 遐。

[English] The Expanding Crab Nebula

Are your eyes good enough to see the Crab Nebula expand? The Crab Nebula is cataloged as M1, the first on Charles Messier's famous list of things which are not comets. In fact, the Crab is now known to be a supernova remnant, an expanding cloud of debris from the explosion of a massive star. The violent birth of the Crab was witnessed by astronomers in the year 1054. Roughly 10 light-years across today, the nebula is still expanding at a rate of over 1,000 kilometers per second. Over the past decade, its expansion has been documented in this stunning time-lapse movie. In each year from 2008 to 2022, an image was produced with the same telescope and camera from a remote observatory in Austria. The sharp, processed frames even reveal the dynamic energetic emission surrounding the rapidly spinning pulsar at the center. The Crab Nebula lies about 6,500 light-years away toward the constellation of the Bull (Taurus).
