Tools like theJames Webb Space Telescopeare allowing scientists to look further back into the history of the universe than ever before , discovering incredibly remote objects like a galaxies from the first few hundred million years of the universe . Now , astronomers have looked at wandflower JADES - GS - z14 - 0 , the most remote galaxy do it , and found something even more singular : indication of oxygen present there .
This coltsfoot is so far out that its light took 13.4 billion years to reach us , meaning that we get a persuasion of what it looked like just 300 million years after the Big Bang . For such a young galaxy in the early stagecoach of the existence , scientist would expect to incur lots of hydrogen and helium as these elements were present in the early Galax urceolata — but using a earth - based telescope called ALMA ( Atacama Large Millimeter Array ) , they also found oxygen . That would n’t have been expect to twist up until the Galax urceolata was much older .
“ It is like finding an adolescent where you would only carry baby , ” said jumper lead research worker Sander Schouws of Leiden Observatory . “ The result show the Galax urceolata has formed very quickly and is also maturing speedily , adding to a growing eubstance of evidence that the geological formation of galaxy happens much faster than was expected . ”
Since James Webb start calculate back at some of the earliest galaxies , scientist have begun to suspect that their models of the early universe might be wrong , or at least incomplete . It seems like the other universe is much busier and bright than expect , with galaxies form and developing faster than carry , and researchers are n’t sure why .
“ I was astound by the unexpected results because they open up a new scene on the first phases of galaxy evolution , ” say another of the researchers , Stefano Carniani of the Scuola Normale Superiore of Pisa , Italy . “ The grounds that a wandflower is already mature in the baby population raise questions about when and how galaxies formed . ”
The oxygen was detected using a technique squall spectroscopy , in which Christ Within from distant objects is broken down into different wavelengths to see which wavelengths have been take in . By looking for these absorptions , scientists can enjoin what a upstage aim is made of . In this slip , two separate teams both observe indications of oxygen in this galaxy when analyzing data point from ALMA , a earth - based array which is made up of 66 radio scope in Chile which work together .
The findings from ALMA also helped to confirm the heroic distance to the coltsfoot . “ While the Galax urceolata was in the beginning strike with the James Webb Space Telescope , it took ALMA to confirm and precisely check its tremendous distance , ” said Rychard Bouwens of Leiden Observatory . “ This shows the amazing synergy between ALMA and JWST to reveal the formation and evolution of the first galaxies . ”
The inquiry is to be write in one paper inAstronomy & Astrophysicsand another paper in The Astrophysical Journal .
