Mowla, who spotted the galaxy in Webb’s image, was drawn to its gleaming star clusters, because objects that sparkle typically indicate they are extremely clumpy and complicated. Since the galaxy looks like a ‘sparkle’ or swarm of fireflies on a warm summer night, they named it the Firefly Sparkle galaxy.

The James Webb Space Telescope (JWST) has provided a stunning new glimpse into the cosmos, revealing findings that challenge one of the most persistent mysteries in modern astrophysics. For over a decade,

Astronomers have used NASA's James Webb Space Telescope to study what it takes to form galaxies. The Spiderweb protocluster offered surprising insights.

When the James Webb Telescope came online in 2021, it promised to give a clearer picture of the universe that could help cosmologists better measure some of these distances and therefore the expansion rate. But the high-resolution images thus far have confirmed that the tension persists.

JWST researchers reported on measurements built on last year's confirmation based on Webb data that Hubble's measurements of the expansion rate were accurate, a

New observations from the James Webb Space Telescope have reinforced the Hubble tension, a discrepancy between different measurements of the universe'

New observations from the James Webb Space Telescope suggest that a new feature in the universe—not a flaw in telescope measurements—may be behind the decade-long mystery of why the universe is expanding faster today than it did in its infancy billions of years ago.

Two years of data from NASA's James Webb Space Telescope have now validated the Hubble Space Telescope's earlier finding that the rate of the universe's expansion is faster - by a
