What I really want to see is the JWST images of Sedna Hubble can only produce one pixel https://esahubble.org/images/opo0414d/ https://esahubble.org/images/op

Apparently JWST was pointed at it a year ago but all they released was an image-less paper on the spectrum?
BTW you know the "deep field" image they use for testing?
I have a new favorite instead. "Abel 2218" just look at that.

- n40487171 3y agoSpectrometers don't always make "images", it's possible they didn't take a picture? Also, that deep field has some amazing gravitational lenses!
- floxy 3y agoWhile the JWST has a larger aperture (6.5 m) than Hubble (2.7 m), the wave lengths it is sensitive to are also longer. So the overall resolution is only between 2 and 3 times better for JWST. So if Hubble can only resolve something to 1 pixel, I'd only expect you'd get at most 9 pixels for JWST.
