James Webb Space Telescope, galaxies and dark matter

Webb telescope scientists forced to reckon with enormous galaxy outliers
The galaxies, each as vast as the Milky Way, are baffling because most scientific models for galaxy evolution suggest processes that would have been slow and inefficient, said Stijn Wuyts, an astronomer from the University of Bath in the United Kingdom.
James Webb Space Telescope finds galaxies pointing toward a dark matter alternative
A group of astronomers analyzing data from the James Webb Space Telescope ( JWST) say some of the oldest galaxies in our universe appear much larger and brighter than expected, suggesting they formed early and grew rapidly — potentially without the influence of dark matter.
James Webb Space Telescope’s data unveils galaxies that could lead to a dark matter revolution
The James Webb Space Telescope has discovered surprisingly large and bright early galaxies. This discovery challenges the traditional understanding of
James Webb Telescope: “Red monster galaxies” problem for the standard model
The James Webb Telescope once again discovered galaxies that form stars so early and so effectively that they don't fit into the standard model of cosmology.
James Webb Telescope makes significant discovery that changes everything scientists thought they knew
Space never ceases to amaze us, but what the James Webb Space Telescope (JWST) just found has changed everything that we know about the universe. The JWST is an advanced version of the 1990 Hubble telescope, which was launched into space in December 2021.
Galaxy Observations Agree With Alternate Theory to Dark Matter
The standard model for how galaxies formed in the early universe predicted that the James Webb Space Telescope (JWST) would see dim signals from small, primitive galaxies. But data are not confirming
James Webb Telescope: galaxy discoveries are set to shake up the standard model
Since its launch, the James Webb Space Telescope has been finding unusually bright galaxies in the early cosmos. Now there is supposed to be an explanation.
