“A quasar with a black hole swallows up a sun a day.”
Australian research team announced in the latest issue of ‘Nature Astronomy’
An Australian-led team of astronomers announced in the scientific journal ‘Nature Astronomy’ published on the 19th (local time) that they had discovered a quasar (quasar), which is believed to be the brightest celestial body in outer space.
Nature Astronomy is an online international journal in the field of astronomy and astrophysics published regularly by Nature every month. Whether or not to publish a paper is decided by three peer reviews.
The researchers said that the newly announced celestial body, a quasar, has a black hole at its center, which grows so rapidly that it can swallow up about one sun a day.
The brightness of this quasi-star is about 500 trillion times the brightness of the sun we see.
Although its shape or photo simply looks like a single dot, scientists suspect that it is an enormous, violent, moving celestial body.
The disk-shaped body orbiting the star’s black hole engulfs other stars in a whirlpool of gas and other material that emits bright light. It’s like a hurricane in outer space.
“This quasi-planet is the most violent of all the planets we have discovered in space,” Australian National University professor Christian Wolf, lead author of the study, told The Associated Press in an email.
This planet was first discovered by the European Southern Observatory during space observation in 1980 and named J0529-4351, but at the time it was thought to be just an ordinary star. Unlike ordinary celestial bodies, quasars, which are quasi-planets, are very active and form the brightest center in the galaxy.
This planet, which was very active until last year, was once traced at observatories in Australia and the Atacama Desert in Chile.
“The most unusual thing is that this quasar looks like an ordinary planet, so it was previously mistaken for an ordinary star,” said Briyambada Natarajan, a professor at Yale University who was not involved in the paper.
According to post-discovery research and computer modeling, this quasar devours about 370 sun-equivalent objects a year. That’s almost one a day. Additional observations and research are needed to calculate the exact growth rate.
This quasar is located 12 billion light years from Earth and is believed to have existed since the beginning of the formation of the universe.
One light year is equivalent to a distance of 5.8 trillion miles.
