The next blue moon isn’t until May 2026, but luckily for you, you won’t have to wait that long to hear the Outside/In team answering listeners’ questions. This time, we’re exploring why blue moons are cool (or even what the heck a blue moon even is) and other seasonably appropriate curiosities.

1. What’s all the fuss about a blue moon?
2. Should we leave the leaves?
3. Which is a more sustainable choice: real or fake Christmas trees?
4. What happens to Christmas tree stumps?
5. What does all that road salt do to the environment?

Featuring Asmeret Asefaw Berhe, Tim Gaudreau, Victoria Meert, and Sujay Kaushal.

Thanks to Outside/In listeners Zoe, Janet, Gio, Alexi, Prudence, Wendy, Mo, and Devon for their questions and contributions.
