[漢羅] M44：鬼宿星團

M44 是咱太陽系附近 ê 星團之一，伊離咱干焦 600 光年遠爾爾。 伊嘛叫做 蜂岫星團 抑是 鬼宿星團。 伊內底 ê 恆星攏足少年 ê，差不多有 6 億歲，太陽是 45 億 歲。 M44 ê 歲數，佮 佇金牛座內底的 畢宿星團 差不多，in 佇太空 ê 運動方式嘛差不多。 所以 in 兩个 去 hŏng 認為講，是 ùi 仝一个大分子雲生出來 ê。 M44 chhāi 佇哩 巨蟹座 內底，是一个 15 光年闊 ê 開放星團，內底差不多有 1000 粒恆星。 這个闊度佇天頂 ê 角寸尺，差不多是 3 粒月娘 (1.5 度) 遐爾闊。 M44 自古早時代就通人知，咱用目睭直接看就看會著。 這个星團 tī 18 世紀編 ê Charles Messier 星表內底，排第 44。 伊去予編入去星表進前，hŏng 講做是一个較暗 ê 星雲、抑是 天頂 ê 雲霧。 一直到天文望遠鏡出現了後，咱才有法度知影星團內底，其實是一粒一粒 ê 恆星。 對有雙筒千里鏡 ê 現代觀星者來講，這个星團是一个有名 ê 觀測目標。 這張星團 ê 團體相片，是用天文望遠鏡 速翕 ê。 星團內底一寡 較黃、較冷 ê 紅巨星，就四界 chhāi 佇較藍、較光、較燒 ê 主序帶恆星之間。 相片內底彼寡 繞射光尖，表示講 in 是星團內底較光 ê 恆星。 這个形是 ùi 望遠鏡 物鏡面頂 ê 十字線來 ê。

[English] M44: The Beehive Cluster

A mere 600 light-years away, M44 is one of the closest star clusters to our solar system. Also known as the Praesepe or the Beehive cluster its stars are young though, about 600 million years old compared to our Sun's 4.5 billion years. Based on similar ages and motion through space, M44 and the even closer Hyades star cluster in Taurus are thought to have been born together in the same large molecular cloud. An open cluster spanning some 15 light-years, M44 holds 1,000 stars or so and covers about 3 full moons (1.5 degrees) on the sky in the constellation Cancer. Visible to the unaided eye, M44 has been recognized since antiquity. Described as a faint cloud or celestial mist long before being included as the 44th entry in Charles Messier's 18th century catalog, the cluster was not resolved into its individual stars until telescopes were available. A popular target for modern, binocular-equiped sky gazers, the cluster's few yellowish tinted, cool, red giants are scattered through the field of its brighter hot blue main sequence stars in this telescopic group snapshot. Dramatic diffraction spikes highlighting the brighter cluster members were created with string crossed in front of the telescope's objective lens.
