What a Star Is (and What It Isn’t)

This week, we begin a month-long exploration of the most familiar objects in the night sky, and wonder why they’re still so often misunderstood.

In this episode, we take a deep dive into what a star really is, and just as importantly, what it isn’t. We’ll talk about how stars form, why they live such turbulent lives, how light escapes their interiors over immense spans of time, and why the stars we see from Earth are not representative of the galaxy as a whole.

Along the way, we’ll challenge common assumptions about color, brightness, and magnitude, explore the strange world of brown dwarves and “failed” stars, and reflect on why nearly everything around us exists because earlier generations of stars lived and died long before the Sun was born.

After the break, we turn our attention to the night sky for February 1st through the 7th. The week opens under the light of the full Snow Moon. We’ll talk about a close lunar encounter with Regulus in Leo, and a selection of star clusters and overlooked regions that still shine through imperfect conditions, including the Beehive Cluster, M67, Monoceros, and a charming little cluster in Orion known as “the 37.”

We also kick off the Star Trails book club with the first three chapters of NightWatch by Terence Dickinson. We’ll discuss why this classic guide remains so valuable, how different editions compare, and why books are still some of the best companions you can bring to the night sky.
