For scientists 2017 is the most fruitful year. Scientists have now found a super-sized black hole. It is the most distant black hole ever discovered. The old and farthest black hole ever witnessed is a celestial brute 800 million times more extensive than the sun which is providing scientists with some wonders about the nature of the universe.
Astronomers on Wednesday declared the black hole, residing at the centre of a highly bright celestial object named a quasar, is located about 13.1 billion light-years away from Earth. The quasar’s light discovered by the researchers dates back to approximately 690 million years after the Big Bang that formed the universe when the cosmos was only 5% of its present age.
The researcher Eduardo Banados of the Carnegie Institution for Science, who led the research published in the journal Nature said that so if the universe was a 50-year-old person, we are seeing a picture of that character when he or she was 2-1/2 years old. When we were looking at further distances, we were also looking for the history because of the time it takes for light to move across the universe. That means this object dates back 13.1 billion years. By way of observation, Earth is about 4.5 billion years old.
Professor Robert Simcoe of the Massachusetts Institute of Technology said that this object provides us with the measurement of the time at which the universe first became illuminated with starlight. Discovering such a massive black hole existing so early in the universe’s history amazed the researchers. Its very existence then challenges current notions about the formation and growth of such objects, they said. “The universe is full of wonders,” Banados said.
Throughout the time of this newest quasar, the universe was arising from the Dark Ages. Stars and galaxies were first resembling, and their radiation is ionising the around hydrogen gas to illustrate the universe. Banados suggest that there are more examples like this out there, between 20 and 100. Quasars, strengthened by gases spiralling at high speeds into an enormous black hole, are identified to inhabit the centre of individual galaxies, sometimes outshining all the stars in those galaxies.
In black holes, gravity has such a high pull that not even light can escape. This black hole was seen gorging material at the centre of the galaxy.
The object was examined using ground-based telescopes in Chile and Hawaii and NASA’s orbiting Wide-field Infrared Survey Explorer.
