- NASA’s James Webb Space Telescope confirmed a new “most distant galaxy” record with MoM-z14.
- The object is seen as it existed about 280 million years after the Big Bang, agencies said.
- Researchers say the find adds to evidence that bright galaxies showed up earlier than many models expected.
NASA’s James Webb Space Telescope has confirmed the most distant galaxy yet seen, catching MoM-z14 as it looked just 280 million years after the Big Bang, NASA and the European Space Agency said on Wednesday. The agencies measured a redshift of 14.44 — how much the universe’s expansion has stretched the galaxy’s light — putting it at the current edge of what telescopes can observe. Nasa
The detection pushes Webb deeper into “cosmic dawn,” the universe’s first few hundred million years, when the earliest galaxies were switching on. Astronomers chase these targets because they offer direct checks on how fast stars and galaxies could assemble after the universe began.
The team said MoM-z14 adds to a growing set of early galaxies that appear far brighter than expected, pressing theorists to rethink how common such objects were at the dawn of time. The galaxy may also help map a transition called reionization, when intense early starlight began to clear a fog of hydrogen gas that once blocked light from traveling freely.
Webb first spotted MoM-z14 in the COSMOS survey field using NIRCam, its near-infrared camera, before confirming its distance with NIRSpec, a spectrograph that splits light into its component wavelengths. NASA said the light has travelled for about 13.5 billion years in a universe estimated to be 13.8 billion years old.
“With Webb, we are able to see farther than humans ever have before … and it looks nothing like what we predicted,” said Rohan Naidu of the Massachusetts Institute of Technology, lead author of a paper on the galaxy published in the Open Journal of Astrophysics. Esa
MoM-z14 belongs to an unexpectedly bright population of early galaxies that researchers said is about 100 times more common than theoretical studies predicted before Webb launched. “There is a growing chasm between theory and observation related to the early universe,” said Jacob Shen, a postdoctoral researcher at MIT.
NASA and ESA said some of Webb’s earliest galaxies, including MoM-z14, show unusually high nitrogen levels, echoing a small class of ancient stars in the Milky Way. “We can take a page from archeology and look at these ancient stars in our own galaxy like fossils,” Naidu said.
With MoM-z14 appearing so soon after the Big Bang, the researchers said there may not have been time for multiple generations of stars to build up nitrogen in the usual way, and pointed to a possible role for supermassive stars. The team also said the galaxy shows signs of clearing the primordial hydrogen haze in its immediate neighbourhood, adding a data point for reionization’s timeline.
The Hubble Space Telescope first pushed the frontier with GN-z11, a bright galaxy seen about 400 million years after the Big Bang; Webb later confirmed that distance, NASA said. “To figure out what is going on in the early universe, we really need more information,” said Yijia Li of Pennsylvania State University, citing more Webb work and NASA’s planned Nancy Grace Roman Space Telescope, designed to survey wide areas in infrared light.
But the search for record-distance galaxies can stumble because nearer objects can masquerade as extreme ones in images, making spectroscopic follow-up critical. “We can estimate the distance of galaxies from images, but it’s really important to follow up … with more detailed spectroscopy,” said Pascal Oesch of the University of Geneva.
NASA said it expects Webb to beat this record again as surveys deepen and more data comes in, while researchers treat MoM-z14 as another sign that the early universe may have built bright galaxies faster than expected. Scientificamerican
