You might have heard of TRAPPIST-1. Discovered in 2017, this system of rocky planets orbiting a red dwarf star has been hailed as the most promising place to search for life outside our solar system.

And now, one of these planets has just got even more exciting. New observations from the James Webb Telescope reveal the most compelling evidence yet: planet TRAPPIST-1e might have an Earth-like atmosphere. Join us to see what JWST found and why this could be huge.
