M 1 :蟹狀星雲
M1: The Crab Nebula

這就是恆星爆炸後留下的爛攤子。 蟹狀星雲是公元 1054 年一顆超新星爆炸的結果,星雲中充滿了神秘的細絲。 這些細絲不僅極其複雜,而且其質量似乎小於最初超新星爆炸時的質量,速度也高於自由爆炸時的預期速度。 這張照片是由美國佛羅里達州利斯堡的一位業餘天文學家在上個月的三個晚上拍攝的。它是以三原色拍攝的,但氫氣的特殊發射提供了額外的細節。蟹狀星雲的跨度約為 10 光年。 在星雲的最中心有一顆脈衝星:它是一顆質量與太陽相當的中子星,但體積只有一個小鎮那麼大。 蟹狀脈衝星每秒旋轉約 30 次。 探索宇宙隨機 APOD 生成器
原文:This is the mess that is left when a star explodes. The Crab Nebula, the result of a supernova seen in 1054 AD, is filled with mysterious filaments. The filaments are not only tremendously complex but appear to have less mass than expelled in the original supernova and a higher speed than expected from a free explosion. The featured image was taken by an amateur astronomer in Leesburg, Florida, USA over three nights last month. It was captured in three primary colors but with extra detail provided by specific emission by hydrogen gas. The Crab Nebula spans about 10 light years. In the Nebula's very center lies a pulsar: a neutron star as massive as the Sun but with only the size of a small town. The Crab Pulsar rotates about 30 times each second.
