Two years ago I posted about how the Event Horizon Telescope Collaboration managed to take the first photograph of a black hole, in particular a supermassive black hole at the centre of the M87 galaxy, one of those galaxies far, far away that we see at a long time ago.
This morning, the same group of scientists released the first photograph of Sagittarius A*, the supermassive black hole at the centre of our very own Milky Way Galaxy. The BBC article I read this morning included the photo of the black hole, which you should definitely check out because of its importance in the history of astronomy. But, for our purposes here on Coffeespoons, I wanted to look at the diagram the designers at the BBC made to explain the photograph.
The designer used some simple white lines with a thicker stroke for the axis and defining features and a thinner line to point to elements of the photo. In particular I like the dotted line for the black hole, because there is no real way to photograph the hole itself since it consumes all the light we would need to image it. Instead, we photograph the “black hole” at the centre of the accretion disk, all the super heated gas and matter slowly swirling around and collapsing into the singularity. We also get two axes to show the size of the ring and that of the black hole itself. The ring measures a diameter of about 63 million kilometres. The distance from the Sun to Mercury, the closest planet to our Sun, is 58 million kilometres.
Well done, science. Well done.

I’ve been searching to see if I could find a better motion graphic of this, alas not. I saw a post on Instagram from the Washington Post that featured a timelapse video or graphic of the spread of the Caldor Wildfire. The Caldor Wildfire presently rages southwest of Lake Tahoe and has now forced the evacuation of South Lake Tahoe, a city of more than 20,000 people.
The motion graphic just does a nice job of simply capturing the spread, in both direction and speed, of the wildfire. Obviously, the whole area could use the inches of rain that Hurricane Ida is dumping on the eastern half of the country.

Yesterday I wrote about some new ICBM silos China is building in its western desert. These things clearly interest me and so I was doing a little more digging when I found this even more recent article, this one from the BBC about an entirely different ICBM silo field that China is building in another western desert.
In terms of data visualisation and information design, we are looking at the same kind of graphic: an annotated satellite photograph. But the story it paints is the same: China is rapidly expanding its nuclear missile arsenal.
Similar to the earlier piece we see dots to indicate missile silo construction sites. But the Federation of American Scientists noted these silos appear to be at earlier phase of the construction process given that sites were still being cleared and prepared for construction activity.
But put it together with the publicly available information from yesterday and, again, we can only draw the conclusion that China wants to greatly increase its nuclear arsenal. And like yesterday we’re left with the same question:
How will the United States and her allies respond?
Credit for the piece goes to the Federation of American Scientists.
We can move from the microscopic things that will kill us to the very big things that will kill us. Nuclear missiles.
Because satellite photography from late June indicated that China is presently building over 100 ICBM silos in its western deserts. China has long had nuclear weapons, but has also long kept its arsenal small, compared to the two nuclear behemoths: the United States and the Soviet Union/Russia. But you don’t begin building over 119 missile silos unless you intend to build ICBMs.
To be clear, this doesn’t mean that China will build 119 missiles. More than likely it’ll be a very expensive and potentially deadly shell game. How many missiles are underneath the silo covers? Can you keep track of them? But even if China builds a fraction of 100, modern ICBMs come with multiple independent reentry vehicles (MIRVs) that allow a single missile to target several cities independently.
We also know that China has been building shorter and more intermediate range ICBMs. But some of those are thought to be equipped with conventional warheads, designed to target and sink American supercarriers in the Pacific. The goal to deny American sea and airpower effective bases to defend Taiwan or other allies in the South China Sea.
We know about this most recent buildup because of a Washington Post article that used satellite photography to pinpoint those new silos.
Of course this isn’t news to the defence and intelligence agencies. For sometime now they’ve been warning of China’s build-out of its military capacities. The question will be is how does the United States and her allies respond?

Okay, technically not Spring Garden Street, but a strip mall along one of Philadelphia’s main arterial city streets. Luckily these aren’t some victims of a serial murderer, but rather the result of Philadelphia being an old city (for the United States). As this article from the Philadelphia Inquirer explains, the bodies were discovered during excavations for new construction at the site.
The reason I shared this today was that this past weekend, I had a pint with a colleague of mine at Yards Brewery located at 5th and Spring Garden. We sat at an outside table along Spring Garden and at some point I recall pointing out that Spring Garden hadn’t always been a street. Originally it only existed west of Broad.
Little did I know that the construction site across the street on that sultry Sunday afternoon was home to an archaeological excavation of an old, long since demolished city church cemetery.
You can use the slider in the article to compare the layout of the intersection in 2021 to that of 1860. I love these old timey maps, especially when working on genealogy. Because while we know the cities where we live today, they didn’t look like we know them 150 years ago. And in lieu of photography, it’s otherwise difficult to try and make sense of our ancestors’ world.
Just a few doors south of the Methodist church we had a bakery and a small alley called Brussels Place. And facing the alley we had what look like a number of small homes or perhaps stables. Larger presumably rowhomes lined the main streets of the intersection.
At the right of the screen, I also remember my colleague and I discussing some of the old-looking rowhomes. They may very well be the same ones depicted on this 1860 map. They are the few survivors as most of the area, as the article points out, was eventually turned into a petrol station that later became the strip mall today fenced off to be turned into flats.
If you were unaware, in the wee hours of Friday, President Trump announced that he had tested positive for the coronavirus that causes Covid-19. It should be stated in the just three days hence, there is an enormous amount of confusion about the timeline as the White House is not commenting. From the prepared statement initially released it seems Trump first tested positive Wednesday. But that statement was then changed to fit the diagnosis in the wee hours of Friday morning. But just last night I saw reporting saying that test was actually a second, confirmatory test and the president first tested positive earlier Thursday.
The timeline is also important because it would allow us to more definitively determine when the president was infected. The reporting indicates that he caught the virus at a Rose Garden ceremony at the White House to introduce his Supreme Court nominee, Amy Coney Barrett. This BBC graphic does a great job showing who from that ceremony has tested positive with the virus.
The photo also does a great job showing how the seven people there were situated. Six of the seven did not wear masks, only North Carolina Senator Thom Tillis did. There is no social distancing whatsoever. And not shown in this photo are the indoor pre- and post-ceremony festivities where people are in close quarters, mingling, talking, hugging, shaking hands, all also without masks.
It should be noted others not in the photograph, e.g. campaign manager Bill Stepien, communications advisor Hope Hicks, and body man Nicholas Luna, have also now been confirmed positive.
The final point is that this goes to show how much the administration does not take the pandemic seriously. Right now the Covid data for some states indicates that the virus is beginning to spread once again. And so maybe this serves as a good reminder to the general public.
Just because you are socialising outdoors does not make you safe. Outdoors is better than indoors. No gatherings is better than small gatherings is better than large, well attended garden parties. Masks are better than no masks. Rapid result test screening is better than no test screening. Temperature checks are better than no temperature checks.
But the White House only did that last one, temperature checks, in order to protect the president before admitting people to the Rose Garden. Compare that to how they protect the president from other physical threats. He has Secret Service agents standing near him (or riding with him in hermetically sealed SUVs for joyrides whilst he is infected and contagious); he has checkpoints and armed fences further out to secure the perimeter. Scouts and snipers are on the White House roof for longer range threats. And there is a command centre coordinating this with I presume CCTV and aerial surveillance to monitor things even further out. In short, a multi-layered defence keeps the president safe.
If you just take temperatures; if you just hang out outside; if you just wear masks; if you just do one of those things without doing the others I mentioned above, you are putting yourself—and through both pre-diagnostic/pre-symptomatic and asymptomatic spreading, others—at risk.
But on Sunday night, Trump campaign strategist went on television said that now that President Trump has been infected, been hospitalised, he is ready to lead the fight on coronavirus. Great. We need leadership.
But where was that leadership seven months ago when your advisors told you in January about the impact this pandemic would likely have on the United States? Where was the leadership in February saying the coverage was a hoax? Where was it in March when he said the virus would go away in April with the warmer weather? Where was it in April when it didn’t go away, when things continued to get worse? Where was it in May when thousands of Americans were dying? Where was it in June when states began to reopen even though the virus was still out-of-control and testing and contact tracing was less available than necessary to contain outbreaks? Where was it in July? And August? And September? Where was the leadership at a Rose Garden party celebrating the nomination of a Supreme Court justice, a party where at least seven people have been infected and one of them, the president of the United States, has been hospitalised with moderate to severe symptoms?
As many of my readers know, I have a keen interest in genealogy. And for me that has often met spending hours—far too many hours—wandering around cemeteries attempting to find memorials to ancestors, links to my history, a context to that soil from a different time.
But if you live in Xinjiang or more broadly western China, and you’re not Han Chinese, you probably don’t have that luxury. The Uighurs, a Turkic Muslim people native to that part of Asia, have long been oppressed by the Chinese central government. Most recently they have been in the news after scholars and leading figures have “disappeared”, after news of re-education and concentration camps (though thankfully I have read nothing of industrialised death camps).
Instead, now Chinese authorities are destroying mosques (not news), but also now cemeteries, as this article in the Washington Post explains.
The piece just uses some simple before and after photography to visualise its point. Sadly it does it to great effect.
I forget who originally said it, but someone once said that we all die, each of us, two deaths. The first time is when we die and our buried in the ground. The second and final time is when the last person who remembers us forgets us.
And we are now watching thousands of Uighurs in western China die for the second and final time.
There is a lot going on in the world—here’s looking at you Brexit vote today—but I did not want to miss this frightening article from the BBC on the melting of Greenland’s ice. It’s happening. And it’s happening faster than thought.
There are several insightful graphics, including the standard photo slider of before and after, a line chart showing the forecast rise of sea levels within the possible range. But this one caught my eye.
The colour palette here works fairly well. The darkest reds are not matched by a dark blue, but that is because the ice gain does not match the ice loss. Usually we might see a dark blue just to pair with a dark red, but again, we don’t because the designers recognised that, as another chart shows, the ice loss is outweighing the gains, though there are some to be found most notably at the centre of the ice sheets. This is a small detail, but something that struck me as impressive.
My only nitpick is that the legend does not quantify the amounts of gain or loss. That could show the extremes and reinforce the point that the loss is dwarfing the gain.

Happy Friday, all. We made it to the end of the week. Though if you are like me, i.e. living on the East Coast, welcome to Hell. As in so hot and humid.
So last month President Trump visited the United Kingdom on a state visit. He drew attention to himself not just because of his rhetoric, but also for his fashion choices. Consequently, the Washington Post published a piece about those fashion choices from the perspective of a professional tailor.
The overall piece is well worth a read if you find presidential fashion fascinating. But how does it qualify for Coffeespoons? A .gif that shows how Trump would look in a properly tailored suit.
Since this is a screenshot, you miss the full impact. The piece is an animation of an existing photo and how that then morphs into this for comparison’s sake.
I really enjoy the animated .gif when it works for data visualisation and story-telling.
This isn’t really a graphic so much as it is an x-ray photograph. But I also can’t get it out of my head. We all know that mobile phones has changed the way we live. But now we have evidence that our use of them is changing us physically. Young people are growing horns or spikes at the back of their skull. Don’t believe, photo:
The article in the Washington Post from which I screen captured the image is well worth a read. But I advise you to not do it on a mobile phone.
