I was surprised it isn't just black - which wouldn't have made for a very good picture of course. It's got a halo of light around it.

Crikey!
Theoretical Physics? Black Holes?
Are you sure this Forum can cope with such erudition?
"...as dry as the Atacama desert".
Looks like the shadow of the light from the infalling material. After a lot of data processed from a lot of telscopes over a fair bit of time, or somat. See this link, more info than bbc but not the full blown paper https://astrobites.org/2019/04/11/th...-a-black-hole/
Measure the whole Surface of the Earth with our own feet. Don Quixote
Think slingshot. Photons trapped in a layer whirling round just above the event horizon then thrown out into space. So it is seen emerging only from the periphery, several times the diameter of the hole. So the central area seen as dark, nothing emanates from there. The colours are only symbolic, it is not visible radiation. The bright side is because of rotation.

Be warned. The next thing these boffins will be telling us is that man has walked on the moon
Visibility good except in Hill Fog
Today, nearly 50 years since Neil Armstrong supposedly walked on the moon the Israeli’s couldn’t even land an unmanned craft there. With all today’s modern technology I would have thought if it was possible to put a man on the moon we would have been going regularly by now.
It never happened, so you missed nothing on those lousy pictures Oracle!

Maybe so, and interesting; but if you want any credibilty attached to your doom and gloom, end of the world, Brexit scenario then where do you stand on how important Johnny Burnette and the Rock'n'Roll trio's The Train Kept A-Rollin' stands in the pantheon - particularly the never-before-heard sound of Paul Burlison on guitar which pre-dated eg Keith Richards' fuzz-tone sound?
