about the episode
Researchers have discovered the most distant active supermassive black hole to date using the James Webb Space Telescope. But it is not very heavy.
Those who have paid close attention have seen messages about this before. But now she is together With some other discoveries officially published. Three black holes and 11 galaxies in total, all of which existed shortly after the Big Bang.
They found one of the black holes at CEERS 1019. This system was already in existence about 570 million years after the Big Bang, and the black hole they found there is the most distant supermassive black hole ever observed. But they are much less massive than other black holes discovered in the early universe. Their mass was a billion times the mass of our Sun, and this mass is only 9 million times. This is also why it had not been seen before: so it was not bright enough for other telescopes.
The other two discovered black holes, also not very massive with a mass of about 10 million times the mass of the Sun, formed after the Big Bang: 1.1 billion years ago and a billion years after it. The 11 spotted galaxies were there very early on, they were already around 470 million to 675 million years after the Big Bang.
With this data and future measurements, the researchers hope to be able to say more about how black holes formed in that period — shortly after the Big Bang.
