Inside the James Webb Space Telescope Conversation on JRE
In this excerpt from Joe Rogan Experience #1904, Neil deGrasse Tyson walks through the James Webb Space Telescope’s design, deployment, and scientific purpose. He compares it with Hubble, explains the engineering challenges of launching a larger observatory, and describes how JWST is tuned to observe infrared light from the early universe and from within dusty star-forming regions.
A Telescope Bigger Than Its Rocket
Neil deGrasse Tyson explains why the telescope had to be folded into a rocket fairing and deployed in space like a series of petals.
Foldable Design and Extreme Cooling
The discussion covers hexagonal mirror segments, sunshield layers, and the engineering needed to keep the instrument extremely cold for infrared observations.
Why Infrared Matters
Tyson describes why infrared is key for seeing early galaxies, stars forming inside gas clouds, and other distant or hidden cosmic structures.
Topics
Hubble vs. James Webb
Tyson contrasts JWST with Hubble and explains how rocket size limited earlier telescope designs.
Engineering and Deployment
The conversation covers the telescope’s segmented mirror, sunshield, and deployment sequence in space.
Infrared Astronomy
Tyson explains how infrared light helps observe the early universe and see through gas clouds.

a telescope specifically tuned to see galaxies born at the edge of the universe and infrared also allows you to see deep into gas clouds now when they're showing you an image like so right here this is The Pillars of Creation which were so named at the time Hubble first attempted this we were Gaga

It's always nice when Neil invites Joe Rogan to his podcast.
It was cool to see Joe Rogan as a guest on StarTalk 😂
I personally LOVE the passion Neil has while explaining this stuff. English is not my first language, but I've been glued to the screen for the past 2 hours. This is amazing.
I listen to Neil every night to go to sleep…not because he is boring but because my brain hears him talking whilst it’s working free of my own interruption and can absorb
No matter how many times I watch Neil ill never get bored of hearing him explaining space
Ngl I have the best smoke sessions listening to Neil explain anything and everything.
