Morning, 

So at some point today we should get our first detailed glimpse of the area around the super massive black hole at the centre of our gallaxy (Sagittarius A)

 https://news.sky.com/story/scientists-to-unveil-first-ever-real-picture-of-black-hole-11687509

"The Event Horizon Telescope (EHT) is a project connecting dozens of observatories to scan the environment directly around the supermassive black hole at the centre of the Milky Way."

"The results of this scan are set to be announced on Wednesday in six major news conferences heralding a breakthrough in humanity's understanding of the universe."

I'm really intrigued to see the results.

Stay tuned.

Astonishing ! From unbelievable artefacts of a mathematical model of gravity through SciFi staple to accepted main stream cosmology through to (potentially) bedroom posters pretty much in a lifetime.

They are truly amazing things to contemplate aren't they.

I often think to myself what the environment of a black hole would be like to a close observer (sort of a mental thought experiment) .    The sheer notion of the power/gravity involved and general conditions that cause an event like that. 

 There can't be much else conceived of that could come close to such a phenomenon .  

Save maybe the big bang.

The collapse of our notions of physical laws, time, and causality.

This is incredible, I had no idea this was about to happen!  I'll keep an eye out for the results

to flying through it to emerge in another universe! 

And possibly for the demons dwelling there then to follow our trail back to Earth...maybe should just stick to our own universe...

You read Caleb Scharf: Gravity's engines ?

No , I'll look into it.

A fairly brief (9 min) video that describes what we're seeing:

There'll be someone on Daily Mail online right now saying: 'It looks nothing like one. What a waste of money'

I note that the image is of the black hole at the centre of a distant galaxy, not ours. The original Sky link is wrong in this respect.

Seriously cool stuff!

Thanks for the suggestion:

"Why [sic] come they don't put the camera in focus?"

"Whoopy do dah. I couldn't care less, I thought it was about Tiger Woods."

"It's like a donut. kinda disappointed"

Indeed - Although Sagittarius A has never been photographed directly, here is a 20 years time lapse of stars orbiting it...

An inter-dimensional portal that resembles the Eye of Sauron.

It should be a horrifying discovery. But I am feeling mainly awe (and thankful for our blue and green orb).

Can't help but notice there's a lack of detail in the shadows.

Yes I noticed that .  I was hoping we might get 2 images while I was watching.

Should have used medium format, say what you like about m4/3, ultimately it just can not realise the range that a good medium format sensor can.

I can't work out whether you're being serious. If not, hats off to you for your deadpan tone!

Lol, pretty much word for word what an old aqauintance of mine just put out on Facebook. Trying to carve a niche out for himself as a rightwing commentator in his small pond.

Jk

You ought to see some of the comments on some US based hobby boards for entertainment value. I have seen everything from "as fake as climate change" to "how can it be 26000 light years away when the universe is 6023 years old". I am in awe of their stupidity.

But joking aside, I am completely blown away by this picture and the international scientific cooperation that produced it. It almost makes me hopeful for the future.

Dark energy and cosmic hyperinflation.  Obviously.
