超新星1604(编号: SN 1604,或称开普勒超新星)是位于银河系内的一颗超新星,位置在蛇夫座内。到目前为止,SN 1604是银河系内最后一颗肉眼可见的超新星,距地球仅4,000秒差距(约13,000光年)。高峰时曾成为全天最亮的恒星,也比金星外的其他行星亮,视星等为−2.5。

开普勒所绘的星图,记录了超新星的位置,以字母"N"标示。(由下数起第四行,左起第四格,蛇夫座的右脚跟)

超新星在1604年10月9日首次被人发现[1]。到10月17日,德国天文学家开普勒发现是次现象,他深入研究后写了一本书钜细无遗地记录此事,书名为《De Stella nova in pede Serpentarii》(蛇夫座足部的新星)。

而在《明史》中对此次超新星爆发也有记载:

超新星1604是当代看见的第二次超新星爆发,前一次发生在1572年(第谷新星)。此后,再无观测到银河系内的超新星爆发,但是河外的超新星则屡见不鲜,最瞩目的有超新星1987A

超新星1604爆发后的遗骸成为了往后发现的同类物体的原型,在四百年后的今天仍然是常常被深入研究的天体
