The 365 Days of Astronomy

The 365 Days of Astronomy

Author: 365DaysOfAstronomy.org Language: English Episodes: 269
Imagine a daily conversation about the cosmos, where each sunrise brings a fresh perspective from a different corner of the globe. That’s the essence of The 365 Days of Astronomy. Born from the spirit of the 2009 International Year of Astronomy, this enduring project has evolved into a genuine community effort, releasing a new episode every single day. You won’t hear the same host each time; instead, the microphone passes to astronomers, educators, enthusiasts, and scientists, each sharing their unique passion and expertise. This structure means the tone and topic can shift wonderfully from one day to the next-you might delve into the mechanics of a black hole on Tuesday and then explore ancient celestial myths on Wednesday. The consistent thread is a shared wonder for the universe, presented in accessible, bite-sized pieces. Managed by Avivah Yamani and edited by Richard Drumm, this daily podcast is a production of the Planetary Science Institute, sustained by listener support. It’s a calendar of the cosmos, offering a daily moment of reflection and discovery that proves you don’t need a telescope to have your perspective shifted. Tuning in regularly builds a habit of cosmic curiosity, connecting the vastness of space to the rhythm of our own days.
