Media and scientist get popular and describe:
- the hole as a "shadow" - is that a good/accurate description really?
- ... there is now a photo of... really... they created an image out of radio wave receptions.. public will feel cheated once they understand.
Big think for sure! But I think that the gravitational waves where bigger.

That it is not a photo - i.e. it is not an image captured from visible light. So it has not been *seen* yet.

Narrow definition, radio astronomers have been constructing "images" at radio frequencies for decades. The electromagnetic spectrum is a lot more than visible light.

So it has not been seen yet.
Research telescopes (including Hubble) use CCDs, not eyepieces or cameras.
There will never be a photo of this.

Never ? what is needed is a very long baseline telescope in order to get enough resolving power - which means retaining phase information about the signal photons across thousands of km. Just because we can't do that today with visible photons doesn't rule it out. It's a matter of engineering and $. Maybe not in our lifetimes though.
There is a huge amount of information in the slim ring of plasma just before the event horizon. Researchers have been looking at this for 2 yrs (?) now and they have presented a still in time, but the raw data is really a movie. Expect more telescopes to join in and computing sophistication will improve th eresolution of the captured image.
This black hole is 50 million light years away and huge. They are also trying to image the black hole in the centre of our galaxy which is much smaller but also a lot closer (26k light years).
What this brings to gravational theory & potentially the unification with quantum physics will not be told for many years if not decades.

This is done optically now with distributed telescopes for better resolution.
