Directions: Read the passage carefully and answer the questions that follow.
It was astronomers who spotted J0529-4351, the most powerful quasar thanks to its brightness 500 trillion times greater than that of the sun. This quasar’s incredible brightness, previously described in a study focused on data from the Very Large Telescope in Chile, comes from an active supermassive black hole (~17 Billion solar masses), which devours the mass at a rate of 1 sun per day.
The mass of this black hole is roughly 17 billion times the mass of the sun, making it the fastest growing black hole known to be. The light from the quasar, which requires 12 billion years to travel to Earth, is of extreme importance in understanding the first stages in the evolution of the Universe.
Understanding the challenges of discovery
Yet, even with this incredible brightness, J0529-4351 was the first star to be identified as a potential stellar source of J0529-4351 in no other studies before. It is more satisfactory than other methods at this sun’s tranquillity and brightness, as this simple computing system can confuse such nearby stars. For the same reason, it was also missed by the Gaia probe. That discovery, made rather recently, emphasises the challenges many astronomers face in doing so for such bright objects.
Implications for future research
The sources assert that these findings open up new possibilities in the research of supermassive black holes and the building of galaxies in the early universe. Going forward, research will concentrate on J0529-4351 using advanced tools like gravitational lenses and the GRAVITY+, upgrading on the VLT Interferometer and the forthcoming Extremely Large Telescope also having the objective of more accurately investigating the secrets of the universe.
