Deocamdata, cea mai veche galaxie cunoscuta este MACS0647-JD, cu o varsta de 13.3 miliarde de ani, adica cu 420 de milioane de ani mai tanara decat Universul. Pozitia sa este (in coordonate J2000):
R.A. 06h 47m 45s.90
Dec. +70° 15' 02".99
In septembrie 2012, o alta galaxie ancestrala fusese descoperita (MACS1149-JD cu varsta de aproximativ 500 de milioane de ani dupa Big Bang).
