SMRTR summary

A newly discovered quasar called EUCL J1729 has set a record as the most distant supermassive black hole ever found, sending light from just 662 million years after the Big Bang. Spotted by the European Space Agency's Euclid telescope, the find deepens the mystery of how black holes grew so massive so early. Euclid also found 11 additional early quasars, shifting the field from studying rare outliers to examining entire populations of ancient black holes.
