A couple of days before the US holiday, Thanksgiving, I will give thanks for the new James Webb Space Telescope and share some early results from it. Specifically I will focus on the increased resolution and sensitivity of JWST in the context of local distance measurements in the hosts of 7 SN Ia and direct comparisons between past results from the Hubble Space Telescope and JWST. We find that systematic errors in HST Cepheid photometry do not play a significant role in the decade-long Hubble Tension, leaving us without a source of error to explain its presence.
