#2This 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.

#3> Because the black hole is about 27,000 light-years away from Earth, it appears to us to have about the same size in the sky as a donut on the Moon.
I'm still sad we can't post donut emojis here. This place sucks.

#4This is some great work, kudos to the researchers working in the Event Horizon Telescope team.

#5> “We were stunned by how well the size of the ring agreed with predictions from Einstein’s Theory of General Relativity,"
And ten thousand physicists sighed disappointingly.

#6I'm looking forward to JWST shots of stuff like this.

Yes, IR better penetrates the dust cloud hiding Sgr A*, so here's hoping.

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.

#10One of the findings they announced at the press conference is that the spin of the black hole is not aligned with the galactic plane but is tilted "towards us" so that it is viewed face on.
How unexpected is that?
