Post a coin with orange peripheral toning and a black center? Or post whatever you like. I just thought this was awesome.

Looks like a donut to me.
..... which makes me miss Bear.
I saw that.....
Really incredible !
just as amazing is the fact that Einstein predicted it and could have never seen anything like it.
Two or three hundred years from now, people will laugh at what we think we know now.
The long wait is over.
I was more than a bit surprised that in the end this first black hole image was from the black hole centered in Messier 87.
All this time I thought we'd get a peek at Sag A-star.
I say let's 'collect 'em all'!!

Here's some black hole toning:
Great transactions with oih82w8, JasonGaming, Moose1913.
Terrific capture. Imagine the zoom on the Event Horizon Telescope. Nothing like it.
I gotta say it looks like a donut too. A glazed donut.
Not that my coin looks like a donut, so don’t get confused.

I could just post a picture of my collection. It's a real money sucker.
Yes-it IS awesome!
More like twenty or thirty years
One small area of confusion in the Times article: interior to the event horizon, matter-energy, space-time do not vanish from existence; we simply cannot observe them.
We know the speed of light changes with the media through which it propagates. Although we can't directly observe it, I wonder what the speed of light is within a black hole, or just interior to the event horizon? Hawking postulated information content exists at the event horizon, but we really don't understand how to interpret or retrieve it. Further, does matter-energy continue to compress as in stellar cores; are their "layers"; is a black hole actually a singularity similar to a monopole, or is there another side -- a sign saying "This Way to the Egress?"
This is the closest I can get.
Send in a probe and let's see what we can see,,,,,,, probably nothing but who knows?
For Gods sake get outta the house 😳
That’s where a lot folks careers went after oil price crash in 2015.

Good job, Rexford !
Now, pop that 10-c off to Alpha Centauri and take a long-base image.
I wonder how many radio telescopes and all their information was processed to produce what they think they see? I think the French have a different term for the astronomical term so as not to confuse it with something else.
Absolutely amazing !!!
I have my own black holes.
My wallet;
My checking account; and
For the past 20+ years my kids (my oldest is out of the nest and my youngest will likely be out of the nest by the end of the year).
Money goes in and never comes back out.
What's at the bottom of that hole?

“No longer available” nice way to say sold-out before it’s on-sale.
There are a couple variations, though.

Edit to add: APMEX has these.
And yet 75% of sellers on eBay can’t take a decent picture of a coin if it’s 12 inches away from them.
One way to think of a Singularity ("inside the black hole event horizon") is not that space-time and matter-energy, and gravity and the nuclear forces and everything and everyplace "disappear" nor is it that they are merely not observable anymore, but that they all sort of collapse into themselves and each other. There is no "there and then", thus no speed (distance/time) and no light (no waves, no photons) and no organization or information.
Black "hole" is probably an unfortunate word choice. Its not a hole: Singularity captures the concept much better when thought about as a region of practicality Infinite density.

The EHT has resolution that could be expressed in terms of spotting the date on a Washington quarter in the grading room at PCGS in California from the steps of the Washington Monument in D.C.
edit to add this cool GIF of a Hubble Pixel resolving to the EHT's image of the black hole.
It is an image.
It is composed of data from direct observations; Just not from electromagnetic waves from the visible spectrum as in this image courtesy Corey S. Powell...

Yes, Black Holes Do Matter.
It's beginning to look like they are necessary for much visible galaxy construction.
Ah, that’s even more impressive than spotting an orange on the surface of the moon, which I’d read last night.

This link has the research papers from this observation, which describes all this. Beware, it is complicated! Just getting the image is complicated enough, to interpret you also have to account for the light being highly bent around the black hole in question.
While I understand the scientific/photographic achievement,, I still do not understand the general excitement (beyond those circles) of this event. Cheers, RickO
I'm sure this is a very exciting time for astronomers. And I have been active in astronomy, more the visual and historical aspects for over 40 years. A local observatory sends out broadcasts to keep the hobby at a fever pitch. Relevance?

Excuse me for being temporarily in awe.
It is a sure sign of the decline here of curmudgeonly behavior, with no small thanks to @She_whomustbeobeyed, that no one has yet compared this to the darkness of a coin dealer's heart.
That particular meme, Colonel, is the proverbial "heart of darkness" which has no bottom!
Wow! Ok so now what? To me it would be looking at an unusual cloud form. At first the "WoW" factor, than the wow is gone! How could this profit anything? Waste of time, that's all I got to say. Sorry, just my

"Jesus died for you and for me, Thank you,Jesus"!!!
--- If it should happen I die and leave this world and you want to remember me. Please only remember my opening Sig Line.Well I think that black holes are an incredible awesome force of nature. And until about 2 years ago, they were really still a theoretical concept. There was evidence for them, but it was not necessarily 100% rock solid. And now we have detected gravity waves from some, and now we SEE one! (Well, around it. It bends light completely around it I think.)
Like logger7 said, this has been an amazing few decades for astronomy. I got my degree in physics, and was always interested in deep theoretical stuff, and the great discoveries since I graduated have been in the sky.
Don't be too disappointed the image is blurry. It did take a telescope the size of the Earth to get enough resolution to see anything at all, which seemed completely impossible not long ago. They are pushing the optical limits a bit!
And almost exactly 100 years since they proved Einstein's prediction of the bending of light due to the sun's gravity, during the May 29, 1919 total eclipse. Not exactly photographic plates this time, but cool to have another "photographic" verification of Einstein's General Theory, 100 years later.
I suspect that if @JoeyCoins and @ricko were around at the time, they would not have been impressed by the first light of Galileo's telescope either.

The image is composed of radio wavelength data, not optical data.
The picture is a symbol - an analog - for what we don't yet understand.
But, but, but... they've had pictures of Philadelphia for years!!!

Kind of looks like "HAL" from the movie "2001" Dave? Dave?
Jobs, Gates, and HAL.
I'm more impressed of who first created "light" to begin with!
