A team from the International Astronomy Center was able to follow and photograph “Quaser” J0529-4351, which is considered one of the brightest astronomical objects in the universe. It was captured and photographed while the “Quaser” reached its maximum height (about 22 degrees) from the Seal Astronomical Observatory in Abu Dhabi, and its luminosity was… The magnitude is 15.7, and the limit magnitude on that day and in that spot in the sky was 17. This image is a collection of several images, and the exposure time for each image is 3 minutes. The “quasar” appears in the image in the form of a star between the two yellow lines, and if this “quasar” is observed “The light of which takes 12 billion years to reach us constitutes a message from the faint lights coming from the early past of the universe, and gives a unique glimpse into the childhood of the universe, according to the International Astronomy Center.
“Quasars” are the compressed areas around a black hole or black holes in the nuclei of active galaxies, where black holes devour the matter surrounding them, and as a result of the collapse of matter during the devouring stage, they emit huge amounts of energy and light, and “quasars” are considered among the brightest cosmic objects. , which means that even very distant objects can be seen or monitored from Earth, as was done yesterday at the Al Khatam Astronomical Observatory.
It is noteworthy that this “quasar” was discovered using the large telescopes of the European Southern Observatory, and that it is not only one of the brightest “quasars”, but it is the brightest object ever observed, as it is 500 trillion times more luminous than the sun, and that the black hole in… This “quasar” broke records, as it devours matter as large as a star the size of our sun every day, making it the largest black hole to date. Its mass is 17 billion times the mass of the sun and it is found in the nuclei of active galaxies, and it is more than 12 billion away from us. Light years, and that the accretion radius of the black hole is approximately equal to the distance between the Earth and the star Alpha Centauri, and it is considered the largest accretion disk in the universe, and that this discovery, formed 1.7 billion years after the Big Bang, may put cosmic models to the test, especially theories of the formation of galaxies and black holes. Giants in the early past of the universe.
This “quasar” was observed through the “Schmidt” survey of the southern sky, in 1980, but it took decades of research and scrutiny to confirm that it is a “quasar”, and it has now been confirmed that the scientific research has been published in the prestigious journal Nature Astronomy on February 19, 2024. Scientific research and analysis on this “quasar” are still ongoing, as astronomers suggest using artificial intelligence and machine learning to help detect “quasars” found in sky survey databases.
