About a year ago, we asked astrophysicist Dr Becky Smethurst why the James Webb Space Telescope is such a big deal. Her answers were pretty exciting, to say the least. So, in the months that have passed since then, what has it found out? What mysteries of the universe has it begun to unravel, and has it lived up to expectations? We got back in touch with Becky for an update.  This is the last episode in this series of the Big Questions Podcast! We hope you've enjoyed learning about everything from Martian craters to the human microbiome. Be sure to look out for our next series, beginning in October 2023, and until then, you can find a catalogue of our episodes on the Oxford Sparks website.
