'''NGC 604'''是位於[[三角座星系]]內的一個[[電離氫區]]，它是[[威廉·赫歇爾]]在1784年9月11日發現的。它是[[本星系團]]最大的電離氫區之一，距離地球約270萬[[光年]]，最長處的直徑約1,500光年（460[[秒差距]]），可見部分的大小是[[獵戶座大星雲]]的40倍，[[亮度]]則是6,300倍。如果在相同的距離上，它會如同[[金星]]般的明亮。像所有的[[發射星雲]]一樣，它的氣體被群聚在中心的大質量[[恆星]][[電離]]<ref>{{Cite web|url=http://antwrp.gsfc.nasa.gov/apod/ap021102.html|title=Astronomy Picture of the Day, November 2, 2000 '''NGC 604: Giant Stellar Nursery'''|publisher=[[NASA]]|accessdate=2007-02-10|archive-date=2007-02-05|archive-url=https://web.archive.org/web/20070205084756/http://antwrp.gsfc.nasa.gov/apod/ap021102.html|dead-url=no}}</ref>。這些恆星大約有200顆是[[恆星光譜|O型星]]和[[沃夫–瑞葉星]]，質量是10<sup>5</sup>[[太陽質量]]，而年齡大約350萬歲<ref name="Barba2004"/>。不同於[[大麥哲倫星系]][[蜘蛛星雲]]中心的星團（[[R136]]），NGC 604是一個更緊湊，更類似於巨大[[星協]]，原型的鱗狀排列星協（''Scaled OB Association''，''SOBA''）<ref name="Maíz-Apellaníz2004">{{cite journal<br />
