New observations from the James Webb Space Telescope (JWST) have corroborated data from its predecessor, the Hubble Space Telescope, to determine something is missing from our recipe of the cosmos.

JWST researchers reported on measurements built on last year's confirmation based on Webb data that Hubble's measurements of ...

This time, scientists analyzed new data from the James Webb Space Telescope, which aligns perfectly with Hubble's findings regarding the expansion rate discrepancy. Published in The Astrophysical ...

After the Hubble Space Telescope studied the oldest-known exoplanet in the galaxy, scientists used the James Webb Space Telescope to learn how planets were able to form in the early universe.

New findings from the James Webb Space Telescope (JWST) bring researchers closer to solving the "Hubble tension," the mystery ...

The availability of the James Webb Space Telescope is finally ... offers the most accurate assessment yet, employing both Webb and Hubble to show that the so-called Hubble Tension may be real.

New observations from the James Webb Space Telescope suggest that ... Riess' team used the largest sample of Webb data collected over its first two years in space to verify the Hubble telescope's ...

The universe appears to be expanding faster than expected, and scientists hope the discovery could lead to new physics.
