Scientists reveal first image ever made of a black hole
WASHINGTON — Scientists on Wednesday revealed the first image ever made of a black hole, depicting its hot, shadowy edges where light bends around itself in a cosmic funhouse effect.
Assembling data gathered by eight radio telescopes around the world, astronomers created the picture showing the violent neighbourhood around a supermassive black hole, the light-sucking monsters of the universe theorized by Einstein more than a century ago and confirmed by observations for decades.
It looked like a flaming orange, yellow and black ring.
“We have seen what we thought was unseeable. We have seen and taken a picture of a black hole. Here it is,” said Sheperd Doeleman of Harvard.
Jessica Dempsey, a co-discoverer and deputy director of the East Asian Observatory in Hawaii, said it reminded her of the powerful flaming Eye of Sauron from the “Lord of the Rings” trilogy.
Unlike smaller black holes that come from collapsed stars, supermassive black holes are mysterious in origin. Situated at the centre of most galaxies, including ours, they are so dense that nothing, not even light, can escape their gravitational pull. This one’s “event horizon” — the point of no return around it, where light and matter begin to fall inexorably into the abyss — is as big as our entire solar system.
Three years ago, scientists using an extraordinarily sensitive observing system heard the sound of two much smaller black holes merging to create a gravitational wave, as Albert Einstein predicted. The new image, published in the Astrophysical Journal Letters and announced around the world in several news conferences, adds light to that sound.
Outside scientists suggested the achievement could be worthy of a Nobel Prize, just like the gravitational wave discovery.
While much around a black hole falls into a death spiral and is never to be seen again, the new image captures “lucky gas and dust” circling at just far enough to be safe and seen millions of years later on Earth, Dempsey said.
Taken over four days when astronomers had “to have the perfect weather all across the world and literally all the stars had to align,” the image helps confirm Einstein’s general relativity theory, Dempsey said. Einstein a century ago even predicted the symmetrical shape that scientists just found, she said.
“It’s circular, but on one side the light is brighter,” Dempsey said. That’s because that light is approaching Earth.
The measurements are taken at a wavelength the human eye cannot see, so the astronomers added colour to the image. They chose “exquisite gold because this light is so hot,” Dempsey said. “Making it these warm gold and oranges makes sense.”
What the image shows is gas heated to millions of degrees by the friction of ever-stronger gravity, scientists said. And that gravity creates a funhouse effect where you see light from both behind the black hole and behind you as the light curves and circles around the black hole itself, said astronomer Avi Loeb, director of the Black Hole Initiative at Harvard. (The lead scientists in the discovery are from Harvard, but Loeb was not involved.)
The project cost $50 million to $60 million, with $26 million of that coming from the National Science Foundation.
Johns Hopkins astrophysicist Ethan Vishniac, who was not part of the discovery team but edits the journal where the research was published, pronounced the image “an amazing technical achievement” that “gives us a glimpse of gravity in its most extreme manifestation.”
He added: “Pictures from computer simulations can be very pretty, but there’s literally nothing like a picture of the real universe, however fuzzy and monochromatic.”
“It’s just seriously cool,” said John Kormendy, a University of Texas astronomer who wasn’t part of the discovery team. “To see the stuff going down the tubes, so to speak, to see it firsthand. The mystique of black holes in the community is very substantial. That mystique is going to be made more real.”
There is a myth that says a black hole would rip you apart, but Loeb and Kormendy said the one pictured is so big, someone could fall into it and not be torn to pieces. But the person would never be seen from again.
Black holes are “like the walls of a prison. Once you cross it, you will never be able to get out and you will never be able to communicate,” Loeb said.
The first image is of a black hole in a galaxy called M87 that is about 53 million light years from Earth. One light year is 5.9 trillion miles, or 9.5 trillion kilometres. This black hole is about 6 billion times the mass of our sun.
The telescope data was gathered by the Event Horizon Telescope two years ago, but it took so long to complete the image because it was a massive undertaking, involving about 200 scientists, supercomputers and hundreds of terabytes of data delivered worldwide by plane.
The team looked at two supermassive black holes, the M87 and the one at the centre of our own Milky Way galaxy. The one in our galaxy is closer but much smaller, so they both look the same size in the sky. But the more distant one was easier to take pictures of because it rotates more slowly.
“We’ve been hunting this for a long time,” Dempsey said. “We’ve been getting closer and closer with better technology.”

What is ‘productivity’ and how can we improve it
From the Fraser Institute
Earlier this year, a senior Bank of Canada official caused a stir by describing Canada’s pattern of declining productivity as an “emergency,” confirming that the issue of productivity is now in the spotlight. That’s encouraging. Boosting productivity is the only way to improve living standards, particularly in the long term. Today, Canada ranks 18th globally on the most common measure of productivity, with our position dropping steadily over the last several years.
Productivity is the amount of gross domestic product (GDP) or “output” the economy produces using a given quantity and mix of “inputs.” Labour is a key input in the production process, and most discussions of productivity focus on labour productivity. Productivity can be estimated for the entire economy or for individual industries.
In 2023, labour productivity in Canada was $63.60 per hour (in 2017 dollars). Industries with above average productivity include mining, oil and gas, pipelines, utilities, most parts of manufacturing, and telecommunications. Those with comparatively low productivity levels include accommodation and food services, construction, retail trade, personal and household services, and much of the government sector. Due to the lack of market-determined prices, it’s difficult to gauge productivity in the government and non-profit sectors. Instead, analysts often estimate productivity in these parts of the economy by valuing the inputs they use, of which labour is the most important one.
Within the private sector, there’s a positive linkage between productivity and employee wages and benefits. The most productive industries (on average) pay their workers more. As noted in a February 2024 RBC Economics report, productivity growth is “essentially the only way that business profits and worker wages can sustainably rise at the same time.”
Since the early 2000s, Canada has been losing ground vis-à-vis the United States and other advanced economies on productivity. By 2022, our labour productivity stood at just 70 per cent of the U.S. benchmark. What does this mean for Canadians?
Chronically lagging productivity acts as a drag on the growth of inflation-adjusted wages and incomes. According to a recent study, after adjusting for differences in the purchasing power of a dollar of income in the two countries, GDP per person (an indicator of incomes and living standards) in Canada was only 72 per cent of the U.S. level in 2022, down from 80 per cent a decade earlier. Our performance has continued to deteriorate since 2022. Mainly because of the widening cross-border productivity gap, GDP per person in the U.S. is now $22,000 higher than in Canada.
Addressing Canada’s “productivity crisis” should be a top priority for policymakers and business leaders. While there’s no short-term fix, the following steps can help to put the country on a better productivity growth path.
- Increase business investment in productive assets and activities. Canada scores poorly compared to peer economies in investment in machinery, equipment, advanced technology products and intellectual property. We also must invest more in trade-enabling infrastructure such as ports, highways and other transportation assets that link Canada with global markets and facilitate the movement of goods and services within the country.
- Overhaul federal and provincial tax policies to strengthen incentives for capital formation, innovation, entrepreneurship and business growth.
- Streamline and reduce the cost and complexity of government regulation affecting all sectors of the economy.
- Foster greater competition in local markets and scale back government monopolies and government-sanctioned oligopolies.
- Eliminate interprovincial barriers to trade, investment and labour mobility to bolster Canada’s common market.

COP29 was a waste of time
From Canadians For Affordable Energy
The twenty-ninth edition of the U.N. Climate Change Committee’s annual “Conference of the Parties,” also known as COP29, wrapped up recently, and I must say, it seemed a much gloomier affair than the previous twenty-eight. It’s hard to imagine a more downcast gathering of elitists and activists. You almost felt sorry for them.
Oh, there was all the usual nutty Net-Zero-by-2050 proposals, which would make life harder and more expensive in developed countries, and be absolutely disastrous for developing countries, if they were even partially implemented. But a lot of the roughly 65,000 attendees seemed to realize they were just spewing hot air.
Why were they so down? It couldn’t be that they were feeling guilty about their own hypocrisy, since they had flown in, many aboard private jets, to the Middle Eastern petrostate of Azerbaijan, where fossil fuels count for two-thirds of national GDP and 90% of export revenues, to lecture the world on the evils of flying in planes and prospering from the extraction of oil and natural gas. Afterall, they did the same last year in Dubai and there was no noticeable pang of guilt there.
It’s likely that Donald Trump’s recent reelection had a lot to do with it. Living as they do in a media bubble, our governing class was completely blindsided by the American people’s decision to return their 45th president to the White House. And the fact that he won the popular vote this time made it harder to deny his legitimacy. (Note that they’ve never questioned the legitimacy of Justin Trudeau, even though his party has lost the popular vote in the past two federal elections. What’s the saying about the modern Left? “If they didn’t have double standards, they’d have no standards at all.”)
Come January, Trump is committed to (once again) pulling the U.S. out of the Paris Climate Accords, to rolling back the Biden Administration’s anti-fracking and pro-EV regulations, and to giving oil companies the green light to extract as much “liquid gold” (his phrase) as possible, with an eye towards making energy more affordable for American consumers and businesses alike. The chance that they’ll be able to leech billions in taxpayer dollars from the U.S. Treasury while he’s running the show is basically zero.
But it wasn’t just the return of Trump which has gotten the climate brigade down. After a few years on top, environmentalists have been having one setback after another. Green parties saw a huge drop off in support in the E.U. parliament’s elections this past June, losing one-third of their seats in Brussels.
And wherever they’ve actually been in government, in Germany and Ireland for instance, the Greens have dragged down the popularity of the coalitions they were part of. That’s largely because their policies have been like an arrow to the heart of those nations’ economies – see the former industrial titan Germany, where major companies like Volkswagen, Siemens, and the chemical giant BASF are frantically shifting production to China and the U.S. to escape high energy costs.
But while voters around the world are kicking climate ideologues to the curb, there are still a few places where they’re managing to cling to power for dear life.
Here in Canada, for instance, Justin Trudeau and Steven Guilbeault steadfastly refuse to consider revisiting their ruinous Net Zero policies, from their ever-increasing Carbon Tax, to their huge investments in Electric Vehicles and the mandates which will force all of us to buy pricey, unreliable EVs in just over a decade, and to the emissions caps which seek to strangle the natural resource sector on which our economy depends.
Minister Guilbeault was all-in on COP29, heading the Canadian delegation, which “hosted 65 events showcasing Canada’s leadership on climate action, nature-based solutions, sustainable finance, and Canadian clean technologies—while discussing gender equality, youth perspectives, and the critical role of Indigenous knowledge and climate leadership” and stood up for Canadian values such as “2SLGBTQI+” and “gender inclusivity.” Once again, in Azerbaijan, which has been denounced for its human rights abuses.
And no word yet on the cost of all of this – for last year’s COP28 the government – or should I say the taxpayers – spent $1.4M on travel and accommodations alone for the 633 member delegation. That number, not counting the above mentioned events, are sure to be higher, as Azerbaijan is much less of a travel destination than Dubai, and so has fewer flights in and available hotel rooms.
At the same time all of this was going on, Trudeau was 12,000 kms away in Rio de Janeiro, Brazil, telling an audience that carbon taxation is a “moral obligation” which is more important than the cost of living: “It’s really, really easy when you’re in a short-term survive, [to say] I gotta be able to pay the rent this month, I’ve gotta be able to buy groceries for my kids, to say, OK, let’s put climate change as a slightly lower priority.”
This is madness, and it underscores how tone-deaf the prime minister is, and also why current polling looks so good for the Conservatives that Pierre Poilievre might as well start measuring the drapes at the PMO.
He has the Trudeau Liberals’ obsessive pursuit of Net Zero policies in large part to thank for that.
The world is waking up to the true cost of the Net Zero ideology, and leaving it behind. That doesn’t mean the fight is over – the activists and their allies in government are going to squeeze as many tax dollars out of this as they possibly can. But the writing is on the wall, and their window is rapidly closing.
Dan McTeague is President of Canadians for Affordable Energy.
