This week we have another longform episode! David got a little obsessed with the James Webb Space Telescope (JWST) a few months ago and spent hours and hours researching and talking to experts so that he can try to explain it here on the podcast for Marques and Andrew. This one is a little dense but if you're even remotely interested in the mysteries of our universe this one is for you. David explains why the JWST is such a big deal and what we hope to discover once it begins sending back pictures.Special thanks to:Paul GeithnerDr. Jonathan McDowellDr. Peter GaoTim DoddSources:How James Webb Orbits NothingWebb vs Hubble (NASA)Fine Guidance Sensor (NASA)JWST FAQ (NASA)Where is Webb?
