Webb spots a new record-setting galaxy, only 280 million years after the Big Bang

The uncertainty of science: Using the Webb Space Telescope, astronomers have now identified a galaxy that formed only 280 million years after the Big Bang, far earlier than their theories of the origins of the universe had predicted.
“The broader story here is that JWST was not expected to find any galaxies this early in the history of the universe, at least not at this stage of the mission,” van Dokkum said. “There are, very roughly, over 100 more relatively bright galaxies in the very early universe than were expected based on pre-JWST observations.”
The data suggests MoM z14 is 50 times smaller than the Milky Way, contains nitrogen and carbon, and appears to be forming stars. The data also found little neutral hydrogen surrounding the galaxy, which also contradicts those same cosmological theories. According to those theories, the early universe should be filled with neutral hydrogen.
The nitrogen and oxygen are also there earlier than expected, and suggest there will be more such galaxies, including some even closer to the Big Bang.

On Christmas Eve 1968 three Americans became the first humans to visit another world. What they did to celebrate was unexpected and profound, and will be remembered throughout all human history. Genesis: the Story of Apollo 8, Robert Zimmerman's classic history of humanity's first journey to another world, tells that story, and it is now available as both an ebook and an audiobook, both with a foreword by Valerie Anders and a new introduction by Robert Zimmerman.
The print edition can be purchased at Amazon. from any other book seller, or direct from my ebook publisher, ebookit.
The ebook is available everywhere for $5.99 (before discount) at amazon, or direct from my ebook publisher, ebookit. If you buy it from ebookit you don't support the big tech companies and the author gets a bigger cut much sooner.
The audiobook is also available at all these vendors, and is also free with a 30-day trial membership to Audible.
"Not simply about one mission, [Genesis] is also the history of America's quest for the moon... Zimmerman has done a masterful job of tying disparate events together into a solid account of one of America's greatest human triumphs."--San Antonio Express-News
