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.

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.

These instruments, like the Hubble Space Telescope, reported a value of around 73 km/s/Mpc. The difference between these numbers is known as the Hubble Tension. "The discrepancy between the observed expansion rate of the universe and the predictions of the standard model suggests that our understanding of the universe may be incomplete,

Findings based on two years of Webb telescope observations Data shows universe expanding 8% faster than expected WASHINGTON — Fresh corroboration of the perplexing observation that the universe is expanding more rapidly than expected has scientists pondering the cause — perhaps some unknown factor involving the mysterious cosmic components dark energy and dark matter.
