Ottawa science enthusiasts who remember the buzz when the first image of a black hole dropped in 2019 are in for an even bigger treat, astronomers are now working to capture the first-ever video of one.
Using a planet-spanning network of radio telescopes known as the Event Horizon Telescope (EHT), researchers are training their collective gaze on the supermassive black hole at the heart of Messier 87, a galaxy roughly 50 million light-years from Earth. If successful, this would be the first time humanity has ever watched a black hole move in real time.
Why Video Changes Everything
A single image tells you a black hole exists. A video tells you how it behaves.
By stringing together multiple observations over time, scientists hope to catch the black hole's accretion disk, a swirling ring of superheated gas and matter, shifting, flickering, and churning as material spirals toward the event horizon. These dynamics could reveal never-before-seen details about gravity, magnetic fields, and the extreme physics at play when matter approaches a point of no return.
CBC's Bob McDonald, host of the beloved Quirks and Quarks, broke down the significance of the project, noting that what we learn about Messier 87's black hole could reshape our understanding of how these cosmic giants interact with the galaxies around them.
How Do You Film Something That Eats Light?
Black holes don't emit light. They absorb it. So what you're actually filming is the shadow of the black hole against the glowing ring of gas orbiting it.
The EHT achieves this by synchronizing radio telescopes across multiple continents, effectively turning the entire planet into one enormous telescope dish. The longer the baseline between dishes, the finer the resolution. It's the same principle behind why big telescopes see more detail than small ones, just scaled up to the size of Earth itself.
Data from these telescopes is compiled and processed using sophisticated algorithms, gradually building up a picture, or, in this case, a sequence of pictures, of the black hole's environment.
What Ottawa Residents Can Take Away
For Ottawans who follow Canadian science journalism, this project is a reminder of how much homegrown science communication matters. Quirks and Quarks has been explaining complex science to Canadian audiences since 1975, and Bob McDonald's ability to translate something as mind-bending as black hole physics into plain language is genuinely rare. CBC Radio's science coverage keeps Ottawa and the rest of Canada connected to the cutting edge of human knowledge.
The University of Ottawa and Carleton University both have active physics and astronomy departments, and stories like this one are exactly the kind of thing that inspires the next generation of Canadian scientists.
What Comes Next
The EHT collaboration hasn't announced a release date for the video footage yet, but the global science community is watching closely. When it drops, it could be the most significant astronomical release since the original black hole image, and a moment worth gathering around the screen for.
