[Interview] We Really Need a Far-Infrared Space Interferometer. Here's Why Oct 01, 2023

Show notes

JWST has shown us what the modern infrared telescope is capable of. But it's not far-infrared. There are no space telescopes operating in that spectrum at the moment. But why? And what would we be able to see if we had one? Let's find out with Dr David Leisawitz, Chief at NASA Science Proposal Support Office.
