An impressive discovery that will shed light on the creation of the universe
The oldest supermassive black hole to date, which dates back to the time of the Big Bang, has been discovered by NASA scientists.
The black hole, which it is estimated to be 10 to 100 million times larger than our sunis estimated to have formed 470 million years after the Big Bang, when the universe was only 3% of its current age.
NASA’s James Webb Space Telescope and Chandra X-ray Observatory spot black hole 13.2 billion light years awayin the UHZ-1 galaxy.
This means that its light has traveled 13.2 billion years to reach our space telescopes – making it a “stunning snapshot of the ancient past”, according to the astronomers.
Researchers believe that the black hole was formed by colossal clouds of gas that collapsed into a galaxy next to a galaxy of stars. The two galaxies merged and the black hole prevailed.
The scientists published their study in the scientific journal Nature Astronomy.
According to the study’s lead author, Akos Bogdan of the Harvard-Smithsonian Center for Astrophysics, the black hole is estimated to weigh between 10% and 100% of the mass of all the stars in its galaxy.
In fact, this size cannot even be compared to the tiny sizes of black holes in our Galaxy and other nearby Galaxies (which reach 0.1%).
