Scientists Get Ready to Capture Mind-Bending Footage of Supermassive Black Hole
For the first time ever, astronomers are on the cusp of capturing a mesmerizing video of a supermassive black hole in action. This groundbreaking observation is set to revolutionize our understanding of these enigmatic cosmic objects and could help unlock some of the universe's biggest mysteries.
The Event Horizon Telescope (EHT), a global network of 12 radio telescopes spanning locations from Antarctica to Spain and Korea, will track the colossal black hole at the center of Messier 87 galaxy over March and April. The goal is to capture footage of the swirling disc that outlines the event horizon – the point beyond which no light or matter can escape.
"This movie campaign is really revolutionary," says Sera Markoff, newly appointed Plumian professor of astronomy and experimental philosophy at Cambridge University. "It's not just because it's technologically extremely challenging, but because it will accelerate our science by an order of magnitude."
The black hole in question has a mass equivalent to 6 billion suns and spans an area equivalent to that of the solar system. Its slow rotation means that these snapshots can be stitched together into a moving sequence, providing unparalleled insight into its behavior.
Measuring the black hole's spin speed is crucial because it could help determine how these objects reached such enormous sizes. If they grow mostly through accretion – gradually accumulating material nearby – they would be expected to spin at incredibly high speeds. In contrast, if they expand mostly through merging with other black holes, each merger could slow them down.
The observations also aim to shed light on the formation of massive jets that channel vast columns of gas out of galaxies, slowing down star formation and limiting galaxy growth. These powerful structures can even alter the evolution of nearby galaxies.
While the movie campaign will take place in the spring, scientists won't be able to analyze the data until next year when it's physically shipped to Germany and the US for processing.
Markoff hopes that her appointment as Plumian professor will inspire more people from underrepresented backgrounds to pursue careers in science. Her own journey was unconventional, with a background in art school and an interest sparked by science fiction and comic books.
