This statement gets me. They couldn't see it because it was too bright. That's wild.

These models are also trained using currently discovered objects, which means they can miss candidates with exceptional properties like J0529-4351.
Indeed, this quasar is so bright that models passed it over believing it to be a star located relatively close to Earth.

This misclassification was spotted in 2023, when astronomers realized J0529-4351 is, in fact, a quasar after having a look at the object's region using the 2.3-meter telescope at the Siding Spring Observatory in Australia.
