Life, but not as we know it?

Chris and Edward discuss some recent stories, such as tantalising possible (emphasis on the possible) detections by JWST of interesting molecules on an exoplanet which coul (emphasis on the could) indicate signs of life. There's also new data on Europa, also from JWST, showing carbon dioxide on its surface - what does this mean? And further afield, astronomers have used ALMA to measure magnetic fields in incredibly distant galaxies, opening a potential new way to study the early Universe.
