The new milestone that the James Webb Space Telescope brings us, and that has to do with a proto cluster of galaxies of enormous magnitude.
Thanks to the technology Now the human being has enormous binoculars in space to be able to see even light years away, and with the premiere of the James Webb a few months ago we managed to see further than ever.
Since its debut, the space telescope James Webb has offered us a series of incredible panoramas and snapshots of the universe, be it comets, galaxies and even black holes, a telescope that allows us to see much further than ever before.
And now astronomers have been able to use this telescope to detect the most distant cluster of galaxies ever found, and this time it is located almost 30 billion light-years away from our planet.
It should be noted that these seven cluster galaxies had been observed before with the Hubble Space Telescope, but its technology did not allow it to know how far away they were or if these galaxies were really united.
Specifically, James Webb has been able to measure the redshifts of these galaxies, a phenomenon caused by the expansion of the universe, which means that the further away an object is, the faster it moves away from us.
“We had known for a while from the Hubble data that there was an interesting overdensity of galaxies. It came as a surprise when we first saw the spectra of James Webb: all seven galaxies were aligned with exactly the same redshift.“, it states takahiro morishita from the California Institute of Technology.
Data on what these galaxies were like 650 million years after the Big Bang
It should be noted that because light takes a long time to travel to the position of James Webb, we now receive data on what these galaxies were like 650 million years after the Big Bang.
They comment that if we could receive the data instantly, seeing how it is today, it is likely that it was a colossal cluster of galaxies that would have already trapped thousands of other galaxies.
“We can see these distant galaxies as little drops of water in different rivers, and we can see that they will eventually become part of a great powerful river.or”, points out Benedetta Vulcani from the Italian National Institute of Astrophysics.
In this way, the astronomers’ simulation comments that this cluster may now be one of the most gigantic clusters of galaxies in the universe.
