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.
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.
'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. "
Webb telescope's largest study of universe expansion confirms challenge to cosmic theory
The findings offer a crucial cross-check for previous Hubble Space Telescope measurements of the universe's mysterious expansion
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.
4K James Webb Space Telescope Snaps 90,000 Light-Year Wreath
The James Webb Space Telescope has captured imagery of spiral galaxy NGC 7469, which is 90,000 light-years in diameter. The galaxy is "roughly 220 million light-years from Earth in the constellation Pegasus,
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 confirms we have no idea why the universe is growing the way it is
A dense cluster of bright stars, each with six large and two small diffraction spikes, due to the telescope’s optics.
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.
