The Impossible Quasar at the Dawn of the Universe

The recent extraordinary discovery of the biggest and brightest quasar of the early universe has intrigued astronomers worldwide. The reason behind this? The quasar - SDSS J010013.02+280225.8 (affectionately nick-named J0100+2802), is far larger than current black hole theories predict it should be[1].

Among the oldest and brightest entities in the universe, quasars eject jets of very bright light that can be seen from lightyears away. It was initially believed that different events were being seen when quasars were observed, but it was later established that our line of sight affected the appearance of the quasar, for example a blazar is a quasar with jets that are pointing towards Earth.
