WISE J224607.57−052635.0(或简写为W2246−0526)[3]是一个特亮红外星系, 2015年,它被宣告为宇宙中已知最亮的星系[3][4][5]。它的光度是太阳的350兆倍[3](太阳(349×1012L☉[1]),与附近较小星系的合并可能是其特别亮的原因之一[3][4][5]。光度是由一个质量为太阳100亿倍的类星体产生的。在类星体中环绕超大质量黑洞的吸积盘 辐射出的可见光和超紫外线,被星系的尘埃吸收,然后以红外线汇出。尽管WISE J224607.57–052635.0是两者之中较小的一个星系,但它是出的能量是银河系的10,000倍。WISE J224607.57–052635.0这个星系是由广域红外线巡天探测卫星发现的,它与地球的距离是125亿光年[1][2][6][7][8]。
