TheBB TriCope in James Webber (JWST) is more than a lot of things, but there are two things better than any other historical historical instrument: which breaks his own records!
Today, the NASA’s $ 10 billion telescopes have also been able to do things, found a galaxy with a 280 million years after The Big Bang, One reason the team behind this research calls a “cosmic miracle.”
Now, as the first and farthest galaxy found, it is “the mother of all the first galaxies,” this new JWST Discover is suited to designate “mama z14.”
“First and foremost, at present, this is the farthest thing that man knows. The title changes in astronomy and meditation on physicate Pieter van Dokkum.
“To put that in the context, sharks are on the ground for a long time.”
Jwst has seen again
Since it begins to send the summer land data of 2022, the JWST heals the discovery of galaxies in so-called “high redshifts.”
Redsohift refers to the wavelength of light from distance and thus the first sources spread and transferred to the “red end” of Electromagnetic spectrum as roaming around space.
The first one and thus more distance something is, the more redshift.
Before discovering Mama Z14, the galaxy holds the title earlier and far JADES-GS-Z14-0existing 300 million years after Big Bang, or about 13.5 billion years ago.
This previous record galaxy has a redshift to OT Z = 14.32, while Mama Z14 has redshift in z = 14.44.
What do we know about the mother of all the first galaxies?
There is a wider context of Mama Z14 observing than the fact that the record is breached for the earliest known Galaxy in 20 million years, however, Van Dokkum explained.
“The wider story here is that JWST is not expected to find any galaxies early in History of the universeAt least not at this time of mission, “Van Dokkum said.” There is, too much, over 100 more bright galaxies than the first universe than expected to be based on pre-jwst observations. “
Also, in addition to discovering this new, earliest, and farthest galaxy, the team understands certain behaviors using JWST.
Researchers know that Mama Z14 are about 50 times less than The Milky Way. The team also measured releasing lines from galaxy, indicating the presence of elements such as nitrogen and carbon.
“Release lines are not unusual; it indicates that the galaxy is still young, with a rapid increase rate to form new stars,” says Van Dokkum. “There are also signs of no many neutral hydrogen gas surrounding galaxy, astonishing: early universe is expected to be filled with neutral hydrogen.
“That requires more good spectra and many galaxies, to check more perfectly.”
The presence of carbon and nitrogen in Mom Z14 indicates that there are first galaxies to discover than this 13.52 billion ages.
That’s because the first galaxies of the universe and their stars are filled with the simplest elements of the cosmos, hydrogen and helium.
Later the galaxies can be populated with more heavy elements, where astronomers are confusing “metal,” as they are scattered by supbs for explosion.
“Mama Z14 is not one of the first things formed in the universe, because the stars of the galaxies are made up of hydrogen and helium,” as van doctors. “This is CAN be part of the first wave of formation of ‘normal’ galaxiesthat is, the first galaxies with elements such as nitrogen and carbon – but we think of it before! “
Like to find even the first galaxies than Mama Z14 and maybe even the first generation, Van Dokkum is confident that JWST is on the task.
He explained: “The JWST keeps pushing the front border where we thought it was, and at this point I wasn’t surprised if the galaxies were found in OT Z = 15 or OT Z = 16! “
Now, Van Dokkum and the rest of this team, led by Rohan Naidu at Kavli Institute for Asrophysissics and Space Research, can celebrate the new land in the first cosmos.
“In a program like this, the whole team is always hoping for a ‘miracle,’ that is some of the candidates extremely early galaxies actually pan out and are not ‘mirages,’ Objects whose colors looks like extremely early objects,” van dokkum concluded. “As we hope for some early things, I don’t think any of us expect to break the recthift record!”
A version checked by the team’s pre-peer research is published in the role-repository site Arxiv.
