We are seeing P352-15 as it was when the Universe was less than a billion years old, or only about 7 percent of its current age, this is near the end of a period when the first stars and galaxies were re-ionizing the neutral hydrogen atoms that pervaded intergalactic space. 'SUPERSTAR' ETA CARINAE ACTS LIKE A GINORMOUS COSMIC-RAY GUN, BUT WHY? Carilli added: Further observations may allow us to use this quasar as a background ‘lamp’ to measure the amount of neutral hydrogen remaining at that time.

This quasar’s brightness and its great distance make it a unique tool to study the conditions and processes that prevailed in the first galaxies in the Universe, we look forward to unraveling more of its mysteries.
