No, JWST has not discovered aliens...
Just clarifying some comments I made in an earlier video that got picked up and twisted by UFO enthusiasts and then again in the media! Remember, any future claims of a potential biosignature detection of a molecule in an exoplanet atmosphere means it could be due to life but also could be unknown chemistry. The jump from there to aliens is ridiculous and what's more, it's bad science communication.

👩🏽💻 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.
