SMACS J0723.3–7327,通常称为SMACS 0723,是在南天星座飞鱼座内,距离地球40亿光年[2]的一个星系团(RA/Dec = 110.8375, −73.4391667)[6][7][8][9]。它是从地球上的南半球可见的一片天空,经常被哈伯太空望远镜和其它望远镜观测到,以寻找遥远的过去[2]。它是詹姆斯·韦伯太空望远镜(JWST)拍摄的第一张全彩影像的目标,使用{{link-en|NIR相机|NIRCam]]成像,包括谱密度,显示了被该星团透镜化的物体,红移意味着它们有131亿年的历史[10]。该星系团先前已由哈伯太空望远镜(HST)以及普朗克[11]和钱卓[12],作为南天大质量星团调查(SMACS)的一部分进行了观测[13]。
在2022年,在SMAC 0723的引力透镜场中,一些当时最古老的大质量星系团在被称为"火花星系"的一个透镜星系中被发现[21],可能包含第三星族星[来源请求]。
