Astronomers have discovered approximately 750,000 quasars, one of the brightest and most powerful objects in the universe. Despite its uninspiring name, J0313-1806 differs from other quasars.This newly-spotted object is the oldest known quasar in the universe, with a supermassive black hole over 13 thousand. Millions of years, in fact, are so old and so big that scientists don’t know exactly how they were formed.

The first quasars were discovered in the middle of the 20th century, but decades later we began to understand what these objects were. Quasars are active galactic nuclei in which the super-massive black holes that hold the galaxy pull matter in to create a gas deposition disk. All matter that collides with each other as it rotates into the black hole emits a large amount of electromagnetic energy, which serves as the hallmark of these objects.For example, J0313-1806 is 1,000 times brighter than all galaxies.

J0313-1806 is definitely 13.03 billion light years away. That means we’re seeing this object when it’s just 670 million years old after the Big Bang. to Astronomers estimate that J0313-1806 will have an estimated 1.6 billion times the mass of the Sun over the observed age. That is not out of line for supermassive black holes elsewhere in the universe. But it took them a long time to absorb matter and enlarge. J0313-1806 There should be no time in the early universe to expand this large.

The team used ground-based instruments such as the Atacama Large Millimeter / submillimeter Array (ALMA) and Mauna Kea Observatories (MKO) to detect J0313-1806 last year. It does not specify the name of the previous record holder for the oldest quasar, which is less than 20 million years old. The current blackhold formation model assumes that the star collapses to become a singular, but “mass”. “Seed” for J0313-1806 must be at least 10,000 Sun Mass to reach 1.6 billion quickly.

The study hypothesized to explain the existence of this bizarre quasar, known as the direct collapse scenario. In this model, it was not the collapse of the star that created the supermassive black hole. But the enormous cold hydrogen gas cloud collapsed inward into a larger black hole than any star source could produce.This could explain why astronomers saw so many massive black holes in the early universe.

Unfortunately, the J0313-1806 is so far away that we can’t gather more details with current technology. However, the upcoming James Webb Space Telescope may be accurate enough for images of objects such as J0313-1806.After years of delays, NASA plans to launch the Webb Telescope in late 2021.
