「繞固定點或中心旋轉,像螺絲的螺紋一樣排列」,1550年代,來自法語 spiral(16世紀),來自中世紀拉丁語 spiralis「繞固定中心旋轉,盤繞」(13世紀中期),來自拉丁語 spira「一圈,折疊,扭曲,螺旋」,來自希臘語 speira「一個繞行,蛇等的圈,扭曲,一個花環,任何盤繞或纏繞的物體(腰帶,繩子)」,來自原始印歐語 *sperieh-,來自基礎 *sper-「轉動,扭曲,纏繞」,但Beekes似乎表示懷疑。相關詞:Spirally。Spiral galaxy的證據出現在1870年;早些時候它被稱為spiral nebula(1846年),在其性質被理解之前。
A spiral nebula has been discovered in the Dog's Ear, so strange and complex, that there is nothing to which it can be likened except a scroll gradually unfolding, or the evolution of a gigantic shell. Some of those nebulae which formerly appeared as nearly circular masses, have now been descried to have numerous luminous filaments streaming out in every direction, and interwoven with streams of stars. [Thomas Dick, LL.D., "The Christian Philosopher," 1846]
在狗耳星座中發現了一個螺旋星雲,如此奇特而複雜,除了漸漸展開的卷軸,或一個巨大貝殼的演變,沒有什麼可以與之相比擬。一些以前看起來幾乎是圓形質量的星雲,現在已被發現有許多發光的絲狀物體向各個方向流出,並與星星的流動交織在一起。[Thomas Dick, LL.D., "The Christian Philosopher," 1846]
