Abstract

As JWST observes much more distant galaxies, it will become harder for the telescope to decipher Cepheids from neighboring stars, Freedman suspects. JWST took images of the same stars as the Hubble telescope, and the data suggest a very similar Hubble constant. Riess presented preliminary Cepheid data from four more galaxies - including one that, at 140 millionlight-years, is among the most distant galaxies in the Hubble telescope observations.
