space telescope images James Webb have served scientists to recognize the galaxy farthest and oldest detected in the universe to date: the so-called JADES-GS-z13-0.
the light of this galaxy it has traveled more than 13.4 billion years to reach the eyes of Webb, who was able to capture it thanks to spectroscopic observations. It is, according to new analysis, one of the first to illuminate the universe.
Near the Big Bang
The galaxy formed 330 million years after the Big Bang, according to researchers.
Currently, JADES-GS-z13-0 It is 33 billion light years from us.
“It was crucial to show that you are galaxies, in fact, they inhabit the primitive universe. It is very possible that the galaxies closest ones masquerade as very distant galaxies. See the spectrum revealed as we expected, confirming that these galaxies they are at the actual edge of our view, some further than Hubble could see! It’s a tremendously exciting achievement for the mission,” says astronomer and co-author Emma Curtis-Lake of the University of Hertfordshire in the UK.
Our “galaxy distant” earlier was detected by Webb’s predecessor telescope, the veteran Hubble Space Observatory. He discovered the equally peculiar name GN-z11. This galaxy was seen to be slightly closer to us, at a time when the universe was only 400 million years old.
His composition
In addition to age, the images of the James Webb they also yielded details about the galaxy’s composition.
The study indicates that these galaxies they have a mass of about 100 million suns and are less than 100 million years old. Also that they formed in a very short time and quickly ionized the hydrogen gas around them.
