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.
4K James Webb Space Telescope Snaps 90,000 Light-Year Wreath
The James Webb Space Telescope has captured imagery of spiral galaxy NGC 7469, which is 90,000 light-years in diameter. The galaxy is "roughly 220 million light-years from Earth in the constellation Pegasus,
New research challenges dark matter theory in galaxy formation
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 the popular hypothesis that invisible dark matter helped the earliest stars and galaxies clump together.
Webb Telescope Uncovers Bright Ancient Galaxies That Challenge Cosmic Theories
Since its launch, the James Webb Space Telescope has identified early galaxies that shine unexpectedly brightly, suggesting rapid maturity and challenging current cosmological models. The James Webb Space Telescope (JWST),
5 beautiful images of distant galaxies captured by NASA James Webb Space Telescope
With highly capable instruments James Webb Space Telescope (JWST) was able to capture the image of a distant galaxy. Arp 107: This image reveals facts about how two galaxies collided hundreds of million years ago and star formation.
New study suggests standard theory of how galaxies formed could be wrong
Dark matter is an essential element of galaxy formation and physics, according to the standard theory of how the universe formed, but a new study suggests that might not be the case.
