Just curious but why?

#12This announcement was released simultaneously with 6 papers that use the newly released data. They are linked in the bottom of the press release and are definitely worth checking out.
10 papers total in this batch.

#13I'm looking forward to JWST shots of stuff like this.
Unfortunately JWST won’t come close to being able to resolve Sgr A*. They measured its diameter in micro-arcseconds, whereas JWST’s limiting resolution will be measured in 10s-100s of milli-arcseconds.
And would it even be able to see past the dust clouds and stars and stuff in front of it?
I mean if they could, they could do another longer term observation like from that clip where you can see stars swishing around it.

JWST is not large enough to have that kind of resolution. EHT collaboration has effective lens size comparable to the diameter of the earth.

GR and quantum field theory don't work together, so at least one of them is wrong, and it would be good to figure out which and how.

#18ithought this was old news from couple of years ago, did i miss something?

Thanks. Can you please point me to some popular science article that explains why the two do not agree with each other?

Yes, IR better penetrates the dust cloud hiding Sgr A*, so here's hoping.
The EHT reveals the black hole shadow of about 50 micro-arcseconds [1], while JWST has resolution of about 0.1 arcsec [2], thus resolution of JWST is more than 2000 worse.
It is physically impossible (regardless of the exposure time) for JWST to resolve Sgr A*.
