Two new analyses of the Hubble tension are based solely on data from the JWST telescope and serve as a check of the measurements using the Hubble Space Telescope (HST), which initially led to the tension in the first place. In the paper today (https://arxiv.org/abs/2408.11770), a value of H0 of 72.6 plus-minus 2.0 km/s/Mpc using JWST data alone is reported. This is also consistent with previous values reported by SH0ES using HST data and consistent with the slightly lower values reported by the CCHP team in another analysis based on JWST data alone (https://arxiv.org/abs/2408.06153) when accounting for the smaller subsample of supernovae used by CCHP. Restricting their analysis to the same smaller subsample as used by CCHP, the SH0ES team reproduces their values, a strong indication of overall agreement. It seems we are very close to a confirmation of the Hubble tension independent from the original HST data.
