  • Four Worlds, One Sun; Plus, a Total Lunar Eclipse
    2026/03/01

    In this milestone 100th episode of Star Trails, we bring the cosmos back home.

    After months of exploring distant stars, nebulae, and black holes, March begins with a tour of our own neighborhood: Mercury, Venus, Earth, and Mars, four rocky worlds born from the same protoplanetary disk 4.5 billion years ago, yet shaped into radically different outcomes.

    We’ll visit Mercury, the tiny planet that helped confirm Einstein’s General Relativity and inspired the hunt for a phantom world called Vulcan. We’ll step into Venus, Earth’s “twin” turned runaway greenhouse furnace, and then we’ll zoom out on Earth itself as if we’re alien astronomers reading its oceans, oxygen, and technosignatures from afar. Finally, we’ll head to Mars, a planet that once hosted flowing water, may have been habitable long ago, and still tempts us with the unresolved question of past life.

    After the break, I nerd out about my electric car and trace an unexpected history of EVs in space, from the lunar rovers parked on the Moon to a Tesla Roadster orbiting the Sun.

    In the sky report, the week’s headline event is a total lunar eclipse: the Full Worm Moon turns coppery red in Earth’s shadow, the only total lunar eclipse of 2026 visible across much of North America. Plus: Jupiter shines in the evening sky, and Mercury and Venus linger low in twilight.

  • How Stars Die (Including the One That Keeps Us Alive)
    2026/02/22

    In this episode, we wrap up our month-long series on stars by exploring their final acts.

    Most stars don’t explode. They grow old. We’ll follow the Sun’s future as it swells into a red giant, sheds its outer layers, and becomes a dense white dwarf held up not by heat, but by quantum mechanics itself. Along the way, we’ll examine planetary nebulae like the Ring Nebula and the Dumbbell Nebula, and look at real red giants such as Betelgeuse and Aldebaran that foreshadow stellar endings.

    Then we turn to the massive stars — the ones that collapse, detonate as supernovae, leave behind neutron stars and magnetars, or cross the final threshold into black holes. We’ll discuss how gravity overwhelms every known force, how black holes are categorized by size, and why even these seemingly eternal objects slowly evaporate over unimaginable timescales.

    In the night sky report, we cover the waxing Moon, a six-planet evening “parade,” Jupiter shining high after sunset, and a beautiful lunar encounter with the Pleiades.

  • The Quiet Majority of Stars
    2026/02/15

    This week we take a nerdy detour into the lives of stars by building a tiny simulated galaxy in Python. We form half a million stars, roll the clock forward 10 billion years, and discover something counterintuitive: nearly all of them are still shining. The stars that dominate our constellations, the bright, showy ones, are statistically the least likely to survive. The night sky, it turns out, is a biased sample.

    From there, we leave the realm of statistics and tour a handful of “highlight reel” stars: neighbors like Proxima Centauri and Barnard’s Star, navigational royalty like Canopus, famous oddballs like Vega, and cosmic heavyweights like Antares and WR 104, the so-called “Death Star” that’s (probably) not aimed at us after all.

    This week's night sky lands in the sweet spot of the month: A New Moon on February 17 brings genuinely dark evenings, followed by a delicate crescent return. Watch the young Moon pass Saturn on February 19, with Mercury about five degrees south.

    Finally, in our book club, we continue with Nightwatch by Terence Dickinson, covering Chapters 4 and 5. We talk old-school printed star charts, seasonal sky “guideposts,” why the Milky Way is a river of unresolved starlight, and Dickinson’s legendary warning about “Christmas trash scopes.”

  • What Stars Do While They’re Alive
    2026/02/08

    Stars are easy to take for granted. They rise, they set, and they seem unchanged from one night to the next. But in this episode of Star Trails, we shift our focus to what stars are actually doing right now, shaping nebulae, building solar systems, regulating star formation, and quietly organizing the structure of galaxies around them.

    We explore stellar nurseries like the Orion and Eagle Nebulae, where young stars actively sculpt their birth clouds, and look at star clusters, both open and globular, as living communities that reveal how mass determines a star’s fate. Along the way, we unpack one of the strangest facts in astronomy: that the smallest, coolest stars may live for trillions of years, far longer than the universe has existed so far, and how we know that’s true.

    Later in the show, we step outside and survey the night sky for February 8–14, demystifying the so-called “planetary parade” by using it as a guide to the ecliptic — the shared path planets follow across the sky.

  • What a Star Is (and What It Isn’t)
    2026/02/01

    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.

  • The Myth of the Perfect Night
    2026/01/25

    What if the problem isn’t the sky, but our expectations?

    In this episode we step back from targets, charts, and techniques to talk about something every stargazer eventually encounters: the myth of the perfect night. Clear horizons, steady seeing, and flawless gear. Astronomy culture often presents these moments as normal, when in reality they’re exceptions. Most nights are compromised, interrupted, or quietly frustrating. It’s the nature of the hobby.

    We explore how social media and memory itself smooth over disappointment, how unmet expectations can drain motivation, and why so many astronomers quietly drift away without realizing nothing is actually “wrong.” From dew-soaked star parties and missed comets to long stretches of waiting and adjusting, this episode hopes to show those imperfect nights still matter.

    If you’ve ever packed up early, felt discouraged, or wondered whether the struggle was worth it, this one’s for you.

    In the second half of the show, we'll turn our attention back to this week's night sky, and check in on recent solar activity that lit up the skies with auroras last week. If you caught the aurora, or tried to and came up empty, I’d love to hear your story. Photos, sightings, and near-misses are all welcome at the show website.

  • Choreography of the Cosmos: Why the Sky Never Stands Still
    2026/01/18

    In this episode, we continue our January series for new stargazers by exploring one of the most quietly mind-bending truths in astronomy: everything is moving, including you. Even when you’re standing motionless in your backyard, you’re traveling through space at extraordinary speed, carried along by Earth’s rotation, its orbit around the Sun, the Sun’s journey through the Milky Way, and the motion of the galaxy itself.

    From that realization, we peel back the layers of motion that shape the night sky. We explore why stars rise and set, why the Moon never shows us its far side, how planets appear to reverse course in retrograde motion, and why familiar constellations are only temporary arrangements. Along the way, we talk about tidal locking, libration, axial precession, stellar proper motion, and even the subtle wobble of the Sun itself around the solar system’s barycenter.

    In the second half of the show, we turn our attention to the backyard with this week’s night sky report, featuring dark, Moon-free skies, brilliant Jupiter, Saturn in the southwest, a close Moon–Saturn–Neptune pairing, and excellent conditions for deep-sky favorites like the Beehive Cluster.

    We also officially kick off the Star Trails Book Club, beginning with NightWatch by Terence Dickinson, one of the most beloved guides to the night sky ever written.

  • Night of the Hunter: A Deep Dive into Orion
    2026/01/11

    This week we slow down and spend the night with one of the sky’s most iconic constellations: Orion. We'll use the mighty hunter as a guide, learning how his stars can point the way to other landmarks in the winter sky, from blazing Sirius to Aldebaran and the Pleiades.

    Along the way, we explore Orion’s rich mythology, his role in ancient cultures, and the remarkable deep-sky objects hidden within his outline, including stellar nurseries, dark nebulae, and the vast structures shaping this region of the Milky Way.

    We also journey back thousands of years to ancient Egypt to examine the intriguing and controversial Orion Correlation Theory, which suggests a connection between the cosmos and the pyramids of Giza. What does the evidence really say, and why does Orion continue to draw humans into stories that link sky and stone?

    To round out the episode, we’ll check in on the night sky for January 11–17, including the Moon’s phase, visible planets, and observing highlights, plus a look at recent space news featuring the discovery of a mysterious “failed galaxy” known as Cloud-9.
