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,

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.

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.

This NIRCam image showcases Pillars of Creation which is rapidly forming new stars which are estimated to be a few hundred thousand years old. This NIRCam image showcases Galaxy cluster SPT-CL J0615−5746 which was first discovered when was Universe was 460 million years old.

This month marks three years since the James Webb Space Telescope was first launched, which still feels something like a miracle given how many years of delays it took to finally get it orbiting our planet.

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,
