Will the JWT be able to see the actual shape of stars and planets rather than just points of light?

- Jabbles 5y agoNo, it would need ~3 orders of magnitude better resolving power to do that, even for the closest star. Definition of parsec: https://en.wikipedia.org/wiki/Parsec https://en.wikipedia.org/wiki/Parsec Angular resolution of JWST: https://jwst.nasa.gov/content/about/faqs/faq.html#sharp https://jwst.nasa.gov/content/about/faqs/faq.html#sharp

- pkaye 5y agoThe Roman telescope coming later this decade might do it. It will have an improved coronagraph that might help see exoplanets. They are using adaptive optics and special lenses in a coronagraph to better mask out the light form the star. But mostly likely that coronagraph on a proposed 15m LUVOIR telescope is where we start seeing things in detail. https://roman.gsfc.nasa.gov/exoplanets_direct_imaging.html https://roman.gsfc.nasa.gov/exoplanets_direct_imaging.html
