Scientists have discovered the oldest black hole yet, formed a mere 470 million years after the Big Bang.
Given the universe is 13.7 billion years old, that puts the age of this black hole at 13.2 billion years.
It's believed to weigh anywhere from 10% to 100% the mass of all the stars in its galaxy, said lead author Akos Bogdan of the Harvard-Smithsonian Center for Astrophysics. That is nowhere near the miniscule ratio of the black holes in our Milky Way and other nearby galaxies — an estimated 0.1%, he noted.
The fact that Chandra detected it via X-ray confirms “without a doubt that it is a black hole,” according to Natarajan. With X-rays"you’re actually capturing the gas that is being gravitationally pulled into the black hole, sped up and it starts glowing in the X-rays," she said. The Webb telescope alone may have spotted a black hole that is 29 million years older, according to scientists, but it’s yet to be observed in X-rays and verified. Natarajan expects more early black holes will be found — perhaps not as far out, but still quite distant.
