Move over Pluto, a new dwarf planet just dropped. Scientists announced that they’ve likely discovered a tiny new planet beyond Neptune, in the far-out ring of icy and rocky bits called the Kuiper Belt. The possible dwarf planet was spotted by the Vera C. Rubin Observatory. Flora talks with Matthew Holman, the astrophysicist who made the discovery.

One more thing: The new dwarf planet is currently called 2026 ED138. We think the name needs a little work. What would you call it? Give us a ring at 877-472-4374.

Dr. Matthew Holman is a senior astrophysicist at the Center for Astrophysics | Harvard & Smithsonian.

Math is the talk of the town in a way that it hasn't been before, thanks to recent developments in AI. And some mathematicians, like Steven Strogatz, are using this moment as a reminder of the invisible ways that math is embedded in our daily lives. That’s the focus of his new book, “Big Math: The Hidden Codes That Run Our World.” He wrote it with mathematician Alex Townsend.

Many of us have gotten sucked into the tiny dramas unfolding in our backyards, or on the bird feeder or the fire escape. But not everyone can turn those observations into a best-selling book.

Author Margaret Renkle joins Host Flora Lichtman to talk about the SciFri Book Club pick for November and December, “The Comfort of Crows: A Backyard Year.” In it, she tells the stories of her own yard over the course of a year to help her make sense of the changes in our world and in her own life.
