  1. We never took (EDIT: detailed) pictures of exoplanets. These pictures are illustrated and fake. The only pictures we have, are spectral lines and so on.
  2. We took a picture of Sagittarius A*, not exactly of the black hole but of the hot gas around it

A black hole itself cannot be seen as it absorbs everything including light, but hypothesis says that black holes do emit some radiation, which we can photograph in the appropriate spectrum.

It actually IS from the black hole. If you read on in that text:

>Hawking radiation reduces the mass and rotational energy of black holes and is therefore also theorized to cause black hole evaporation. Because of this, black holes that do not gain mass through other means are expected to shrink and ultimately vanish.

It's not a dumb question given how the scientific community often present images to the general non technical public without properly explaining that they are completely made up representations of how these astronomical entities might look.

We have "data" of exoplanets. Low rez maps spectrograph, thermal etc.

We have not the resolution yet. Picture of the forge of God voyager would only be a pixel away from sun on jwt image. We talking things so far away they don't even take up a pixel at current resolutions. Give it time, ten years from now we will have doubled or maybe even quadrupled resolution.
