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,

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.

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,

Recent observations from the James Webb Space Telescope (JWST) challenge the previously held cosmic theory on the universe's expansion.

A dense cluster of bright stars, each with six large and two small diffraction spikes, due to the telescope’s optics.

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.
