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.
James Webb Space Telescope's First Targets
NASA released full color James Webb Space Telescope images of the Carina Nebula, exoplanet WASP-96 b, Southern Ring Nebula, Stephan’s Quintet and SMACS 0723. Here's a preview of the 5 targets from previous observations and an artist impression.

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'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.

Cracks in cosmological theory: James Webb telescope is challenging what we know about the universe
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.
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.
