She says that she has used many telescopes. Are you doubling down on your claim that her statement applies only to space telescope, despite its general nature?
Can you please explain why space telescopes can't determine distance but that Earth telescopes can?
I never said space telescopes can't determine anything. The point you are not 'addressing' is that your sig quote comes from a researcher that based the information on data from a NASA space telescope. In case you're unclear on how the data was derived from a NASA telescope in space, here's the original article from Barmby and others:
From Barmby’s paper which is cited in the article where you got your cherry-picked sig quote:
Galactic Cepheids with Spitzer: II. Search for Extended Infrared Emissionhttps://arxiv.org/pdf/1011.3386.pdf"A deep and detailed examination of 29 classical Cepheids with the
Spitzer Space Telescope has revealed three stars with strong nearby extended emission detected in multiple bands which appears to be physically associated with the stars...
Nevertheless, our direct evidence that mass loss is active during the Cepheid phase is an important confirmation that these processes need to be included in evolutionary and pulsation models of these stars, and should be taken into account in the calibration of the Cepheid distance scale."
So do you now believe in NASA acquired research and data?
