1 rich Libsyn https://www.libsyn.com 90 600 From Wednesday, March 25, 2026. In this special episode, funded by the National Science Foundation, we’re taking a break from the headlines to share the background story of comets. Today, we’ll focus on the origin of comets and their basic anatomy, and in future episodes, we’ll dive deep into how comets are discovered, what we can learn from them, and how they can literally and figuratively impact our world. &amp;nbsp; We've added a new way to donate to 365 Days of Astronomy to support editing, hosting, and production costs.&amp;nbsp; Just visit: https://www.patreon.com/365DaysOfAstronomy and donate as much as you can!
