🔴 [Interview+] No YT ads https://www.patreon.com/collection/44300 👉 Previous interview about the DICER telescope: https://www.youtube.com/watch?v=VLsWeMYh7fQ James Webb can't resolve Earth-size planets around Sun-like stars. Not just because of the contrast but also because of the diffraction limit. To do that you need a mirror of 20+ meters. But what if you increase the size in just one direction? You get the required resolution but keep the mirror relatively small and easy to transport. This is the idea behind the Rectangular Mirror Telescope. 🟣 Guest: Dr. Heidi Jo Newberg https://faculty.rpi.edu/heidi-newberg 📜 The case for a rectangular format space telescope for finding exoplanets https://www.frontiersin.org/journals/astronomy-and-space-sciences/articles/10.3389/fspas.2025.1441984/full 00:00 Intro 01:50 The challenge of resolving Earth-like planets around Sun-like stars 09:57 Rectangular telescope 23:21 Hunting for exoplanets 31:01 Update on the DICER telescope https://youtu.be/VLsWeMYh7fQ?si=h4vFx0YqsYytcsQQ 36:39 Current obsessions 45:10 Final thoughts 📰 GUIDE TO SPACE NEWSLETTER Read by 70,000 people every Friday.
