NASA's James Webb Telescope Reveals Universe Expanding Faster Than Thought
The rate of expansion of the universe today is a figure known as the Hubble constant, which is typically measured in units of kilometers per second per megaparsec (km/s/Mpc), where a megaparsec (Mpc) is about 3.26 million light-years.
'Our understanding of the universe may be incomplete': James Webb Space Telescope data suggests we need a 'new cosmic feature' to explain it all
"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. "
James Webb telescope confirms we have no idea why the universe is growing the way it is
Astronomers can't agree how fast our cosmos is expanding. A new James Webb Space Telescope study has made the crisis even worse.
Webb telescope's largest study of universe expansion confirms challenge to cosmic theory
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.
James Webb Space Telescope finds smallest asteroids ever seen between Mars and Jupiter
By reverse-engineering James Webb Space Telescope (JWST) exoplanet data, a team of astronomers just spotted dozens of tiny asteroids — including the smallest ever seen in the main belt between Mars and Jupiter.
Webb telescope confirms the universe is expanding at an unexpected rate
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.

James Webb Space Telescope Exposes a Cosmic Mystery That Could Change Everything We Know!
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,
Cracks in cosmological theory: James Webb telescope is challenging what we know about the universe
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.
James Webb telescope data suggests undiscovered cosmic force could be behind Universe’s expansion
There is something missing in our understanding of the Universe to explain its expansion, known as dark energy, that began after the Big Bang, according to a new study using James Webb Space Telescope observations.
