For us on Earth, the brightest object in heaven is without a doubt the sun. But this fiery glow of light fades in comparison to quasars – giant, light-hearted galaxies that radiate enormous amounts of energy.
Astronomers believe that quasars like monstrous hungry black holes in the center of the young galaxies. The light emitted comes from an explosion of energy when the objects spirally fall into the gravitational vortex of quasars, where they are heated to temperatures of several degrees hot in this process.
It has been considered that quasars are far more in the universe about 10 billion years ago, making them an object of great interest to astronomers who study the early evolution of our cosmos.
According to the researchers, the newly discovered quasar was active when the universe was less than a billion years old – when the first galaxy was created in the universe.
12.8 billion years later, Hubble's telescope has now picked up the light of the object – 600 trillion times brighter than our Sun. This wins the last such record that has a quasar, equal to only the light of just 420 trillions of Suns.
A team of researchers from the University of Arizona Posted in their findings Astrophysical letters of the journal.
"We do not expect to find many quasars brighter than the one in the whole visible universe," He said Xiaohui Fan, a leading researcher at the University Press.
How can something so bright be overlooked by telescopes that actively seek such phenomena? Simply put, the quasar is almost universally spaced – 12.8 billion light years. In fact, it is only seen because of the rare physical phenomena called "gravitational treatment".
Gravity forces that are very strong have the power to literally bend & # 39; the path of light that passes through them. In the case of newly discovered quasar, the quasar light was distorted approximately halfway between the quasars and the Earth.
This process increased its intensity of quasar 50 times and also divided the quasar image so that it was simultaneously visible at three different points in the space.
Without this high level of increase, it would make it impossible for us to see the galaxy, said Feige Wang, another member of the team, University Press.
"We think there might be 10 to 20 such facilities we did not find because they would look unclear, and the colors would not be red shifted," Fan said. "This means that our traditional way of finding quasars may not work, and we have to find some new, big information to expand our search."
Kvazar was first observed in the Earth-based telescope called the Multi-Mirror Observatory in Arizona after which scanned objects were detected in archive data from Pan-STARRS1 in Hawaii, the Infrared Telescope Hemisphere Survey in the UK and the WISE telescope in orbit.
Finally, Hubble confirmed it as a quasitor subjected to & # 39; objectivity & # 39; thanks to the clearer view that comes from the universe.
