The Black Hole at the Centre of the Galaxy

That sounds like a title from a 1960s or 70s SF story.
It isn’t though.
What was more or less theoretical then is real now.
And Sgr A* at the centre of the Milky Way has finally been photographed (well at radio wavelengths. The main image is composed of X-ray and infra-red data and spans 7 light years. By contrast the inset of the black hole’s surroundings is only ten light minutes across.)
No doubt you’ve already seen this but it’s worth posting anyway.
The picture is from Astronomy Picture of the Day for 13/5/22.
