Dr. Becky | Black hole image gets AI upgrade (Messier 87* Event Horizon Telescope) @DrBecky | Uploaded 1 year ago | Updated 2 days ago
The Event Horizon Telescope released the first ever image of a black hole in 2019. A telescope that combines multiple radio dishes across the entire Earth to observe tiny pieces of the overall image, then fills in the remaining gaps using machine learning (a branch of artificial intelligence, AI). This month the image has had an upgrade ("can you enhance that?"), with a new AI algorithm used to generate the image from the same data. So how does this new algorithm differ from the first? #blackhole #eventhorizontelescope #ai

👩🏽💻 I'm Dr. Becky Smethurst, an astrophysicist at the University of Oxford (Christ Church). I love making videos about science with an unnatural level of enthusiasm. I like to focus on how we know things, not just what we know. And especially, the things we still don't know. If you've ever wondered about something in space and couldn't find an answer online - you can ask me! My day job is to do research into how supermassive black holes can affect the galaxies that they live in. In particular, I look at whether the energy output from the disk of material orbiting around a growing supermassive black hole can stop a galaxy from forming stars.
