We recently wrote about the picture that this James Webb Space Telescope he captured Saturn. As pointed out several times, this new scientific tool can help scientists study not only nearby celestial objects (perhaps within the solar system), but also more distant ones. soon after -in cosmic terms- The Big Bang.

One of the latest news concerns the discovery of three supermassive black holes which would emit the electromagnetic radiation it captured JWST extension only 1.1 billion years after the Big Bang, 1 billion years after the Big Bang and 570 million years after the Big Bang. In human terms it is so “much time” but when you think of the universe, it’s actually a much shorter time. That was the result of the first analyses.
The James Webb Space Telescope and supermassive black holes
Second what is reported It was possible to discover this thanks to the research called Cosmic Evolution Early Release Science (or simply CEERS). supermassive black hole The most distant active substance ever observed (570 million years after the Big Bang) is named CEERS 1019. Among its distinctive features is that it is the lowest-mass supermassive black hole among the black holes currently known in the early Universe. In particular, its properties indicate 9 million solar masses, i.e. similar (albeit more massive) than that present at the center of the Milky Way.
One of the questions scientists need to answer is “How could a black hole with these properties form so early?”. Answering such questions, in addition to being able to observe other primordial black holes and galaxies, is crucial for understanding the early stages of the evolution of the Universe, but also its future. One of the assumptions about CEERS 1019 is that it formed after the merger of two or more galaxies, which determines its mass but also its activity, including star formation.
Thanks to James Webb Space Telescope However, two supermassive black holes have also been identified. It’s about CEERS 2782which existed when the Big Bang had only lasted 1.1 billion years CEERS 746, existed 1 billion years after the Big Bang. Both have a mass of about 10 million solar masses each and are therefore quite quiet “Light”. The second is then surrounded by a dust cover, which is probably also related to a particularly intense phase of star formation.
The overall picture of CEERS survey The NIRCam image has a width of 23 arc minutes and was obtained with observations made on December 21, 22 and 24 last year. In order to capture the greatest possible amount of information, the F115W, F150W, F200W, F277W, F356W and F444W filters were used. Instead, analysis of black holes was done to correctly determine their properties (including distance and age). NIRS spec.
