The massive gravity of the MACS0647 galaxy cluster acts as a cosmic lens, refracting and magnifying light from the more distant MACS0647-JD system. Due to the triple lensing, we see the system simultaneously in three places, which are marked with numbers and placed in separate blocks on the right (OV1, OV2 and OV3). MACS0647-JD has a redshift of about z=11, which means that the galaxy was formed only 400 million years after the Big Bang.
