First image of a black hole

Well zoom really isnt the correct terminology. But I get your meaning. Its reading light and radio frequency. The longer we can "see" it the better the pic. Which is why this array works. As the earth spins and the first telescope gets out of alignment the next one pics up the signal and continues monitoring. If you look at the pics of the "telescopes" you will see its a dish not a lense.
You are just being inflammatory. I think you are to smart to not believe this and you also like to push buttons.
We can, only because that thing is supermassive. It sucks all the oxygen out of the room, as they say. Plus it's accretion is a mini-galaxy of its own.
This whole thing may have already blown up. the light we're seeing is very old. It's been coming almost forever for a distance we can't imagine, and those photons got here without getting blocked out. It's amazing how empty space is, and how small a photon.
(Not just photons of course. A spectrum of EMR)
Hello; My guess is it is something like computer graphics. May be something like the actual thing or more likely an approximation. Maybe like a weather map we see on the evening news. Millions of bits of data fed into a program. Sort of like hurricane predictions maybe where they sometimes show multiple possible paths depending on which computer model they use.
Back before they sent the Voyagers out the astronomers had books about how they thought our solar system was. Then with new evidence they had to change the texts. Pretty much the same with the dinosaurs. Every decade or so some new bit of data rewrites bits and pieces of the story.
I still find it of much interest. Even if the image is not like a true photo it is representative of the data. An interpretation perhaps but still in a sense real.

Yes exactly its an extrapolation of the data. Its a pic based off of actual light wavelengths, radiation, and radio frequencies. All of this is gathered by the array and computers put together a picture, it's a true picture based off of data. Like an MRI its an actual picture again but its based off data received back to a computer gathered by radio waves sent out. But in the case of the black hole we are just receiving the info because we have pointed this super sensitive array of dishes at it.
Pluto is quite small compared to this enormous black hole, it is bigger than our entire solar system.
There are photographs, and then there are images which are not photos.
Just because an image isn't a photo doesn't mean it isn't a "real picture".
But it can mean it displays radiation not normally visible to the human eye.
In most cases they computer-shift the frequencies in the image to make it more visible to us.

Yup, I can attest to this having worked in library digitization for years. All anyone at work talks about is “big data” with reference primarily to images.
