The Sturgeon Moon and the Fossil in the Dark

This week we bask in the glow of the bright Sturgeon Moon, trace the shifting positions of planets from twilight to dawn, and watch as a few late-season meteors streak across the sky.

Later in the show, we journey beyond Neptune to meet a newly discovered distant object named Ammonite—a cosmic fossil whose strange orbit may upend one of the most compelling mysteries in astronomy: the existence of Planet Nine.

We'll explore how this icy world fits into a tiny family of ultra-distant objects known as sednoids, and why its misaligned path challenges the idea of a hidden giant planet at the edge of our solar system.
