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.Connect with us on Bluesky @startrails.bsky.social or YouTube @TheStarTrailsPodcast.If you’re enjoying the show, consider sharing it with a friend!

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.Connect with us on Bluesky @startrails.bsky.social or YouTube @TheStarTrailsPodcast.If you’re enjoying the show, consider sharing it with a friend!

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.Connect with us on Bluesky @startrails.bsky.socialIf you’re enjoying the show, consider sharing it with a friend! Want to help?

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.Connect with us on Bluesky @startrails.bsky.socialIf you’re enjoying the show, consider sharing it with a friend!

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.Connect with us on Bluesky @startrails.bsky.socialIf you're enjoying the show, consider sharing it with a friend!

The first episode of a new year is a good time to slow down, zoom out, and reset. In this episode, we welcome new and returning listeners alike for a thoughtful reintroduction to stargazing, one that sets aside checklists, gear anxiety, and the pressure to “do it right,” and instead focuses on patience, curiosity, and learning the sky where you are.Along the way, the episode explores the idea of the sky as a clock, the power of naked-eye and binocular observing, and the winter night sky anchored by Orion, Jupiter, and the Great Nebula.It also branches into a backyard stargazer’s reading recommendation (Nightwatch by Terence Dickinson) and a fascinating moment from astronomy’s past, the long search for the nonexistent planet Vulcan, and how Einstein’s theory of general relativity finally explained Mercury’s strange orbit. This episode sets the tone for the year ahead: astronomy as a practice, not a performance.Connect with us on Bluesky @startrails.bsky.socialIf you're enjoying the show, consider sharing it with a friend!

As the year winds down, we make one last stop beneath the night sky for the week of December 21–27, marking the arrival of the winter solstice, the longest night of the year and a quiet turning point in Earth’s journey around the Sun.In this short holiday episode, we reflect on what the solstice means from an astronomical perspective, why ancient cultures saw it as a rebirth of light, and how it gifts modern stargazers with long, early nights and some of the most iconic sights in the sky.We tour the familiar winter constellations as Orion rises into prominence, with the Orion Nebula, the Pleiades, Sirius, and the steady guideposts of the northern sky all on display. This week also features some of winter’s planetary beacons, with Jupiter blazing brightly, Saturn lingering quietly in the early evening, and Mercury making a brief predawn appearance for sharp-eyed observers.The episode also includes a spoiler-free book recommendation for listeners who enjoyed November’s deeper dives into time dilation, interstellar travel, and the limits imposed by physics. Drew shares thoughts on Project Hail Mary by Andy Weir, author of The Martian.Finally, as a holiday gift to listeners, we introduce Liminal Horizon, a new music project featuring three albums of space-inspired, planetarium-style music designed for stargazing, night drives, and quiet contemplation.Connect with us on Bluesky @startrails.bsky.socialIf you're enjoying the show, consider sharing it with a friend!

For the season finale of Star Trails, we’re building a “time machine” the only way we know how: with physics, not plot holes. Drew takes a tour through the time-travel stories that shaped his 80s childhood—Back to the Future, Star Trek IV, The Time Machine, Bill & Ted, and even Disney’s wonderfully unhinged The Black Hole—and then sets them beside the actual rules of our universe. We’ll look at the real ways you can travel into the future using speed and gravity.Along the way we’ll ride with nuclear-pulse starships, bust the myth of the Bussard ramjet, and imagine skimming just outside the maw of Sagittarius A*, the supermassive black hole at the center of the Milky Way. We’ll talk about why time only runs forward, what it really means to “move through spacetime,” why black holes make clocks crawl, and how modern quantum ideas try, and mostly fail, to sneak backward time travel in through the side door without breaking causality.In the second half of the episode, we park the starship and focus on the actual sky. December is one of the richest observing months of the year, so while the podcast takes a short holiday break, you’ll have a clear roadmap: the final Cold Supermoon of the year, the Geminid and Ursid meteor showers, Mercury’s dawn cameo, Jupiter and Saturn in the evening, and the full cast of winter constellations. We’ll lay out a simple three-session observing plan to carry you through the month: supermoon and giants, Geminid weekend, and a quiet solstice night under the Ursids.It’s an episode about time travel that ends with the most accessible time machine we have: walking outside, looking up, and catching ancient photons from the deep past on a cold December night.Connect with us on Bluesky @startrails.bsky.social, or if you prefer listening on YouTube, visit our channel @TheStarTrailsPodcast.If you're enjoying the show, consider sharing it with a friend!

This week, we’re doing something chaotic: we’re mapping the entire history of the universe onto the musical eras of Taylor Swift. And yes, the science is absolutely real.From the Big Bang to the heat death of everything, each of Taylor’s albums becomes a chapter in the cosmic timeline. We’ll travel through the Primordial Universe, the formation of the first stars, galaxy evolution, black hole fireworks, the rise of dark energy, and the long, cold future of the cosmos — all through a Swiftian lens.Later in the episode, we return to our usual sky tour. We’ll explore the waxing crescent Moon, bright views of Jupiter and Saturn, and the early arrival of the winter constellations. And we’ll take a moment to marvel at Hubble’s breathtaking new mosaic of the Andromeda Galaxy, detailed enough that you can zoom in and see individual stars in another galaxy.Think of this episode as a cosmic mix tape!Connect with us on Bluesky @startrails.bsky.social, or if you prefer listening on YouTube, visit our channel @TheStarTrailsPodcast.If you're enjoying the show, consider sharing it with a friend!

This episode begins with auroras and interstellar objects and ends somewhere much closer to the heart. After catching up on the week’s sky – dark moonless nights, Mercury in the dawn, meteor activity, and the quiet unraveling of comet 3I/Atlas – we shift into something different.We’ll explore the idea of “sad astronomy”: the loneliness of deep space, the slow death of stars, the fragility of spacecraft, the silence of the cosmic void, and why so many stargazers feel a mix of awe and melancholy when they look up.Along the way we wander through pop culture – the films Contact, and Interstellar, the Challenger and Columbia tragedies, the ghost glow of old light, the Arecibo message, Voyager’s endless journey, and the overview effect, the transformative shift astronauts feel when they see Earth from above.It’s a meditation on distance, death, meaning, and the strange comfort found in the cold geometry of the cosmos.Connect with us on Bluesky @startrails.bsky.socialIf you're enjoying the show, consider sharing it with a friend!

This week on Star Trails, we let the universe decide.We fire up a real quantum computer to generate pure randomness — the seed for a million-universe simulation of the famous Drake Equation. Each run explores how many intelligent civilizations might exist in our galaxy, from barren voids to thriving cosmic metropolises. The results are startling, the implications profound, and the method delightfully nerdy.Along the way, we revisit the roots of the Drake Equation, the strangeness of quantum mechanics, and the poetry of probability. Then we step outside to the real night sky: the waning Moon, Saturn’s thinning rings, Jupiter’s bright rise, and the Taurid fireballs streaking through November darkness.I also share how I photographed the recent Full Beaver Moon using Stellarium, PhotoPills, and The Photographer’s Ephemeris.This episode blends code, cosmology, and contemplation.Links mentioned:Sampling the Drake Equation with PythonMy Full Beaver Moon CityscapePhoto tools: Stellarium, PhotoPills, and The Photographer's EphemerisFor more episodes and resources for backyard astronomers, visit www.startrails.show.

This week on Star Trails, we explore the messages written across the cosmos — from faint comets in our own skies to the coded signals we’ve sent into the void. Drew shares a quick report from his local astronomy club’s fall star party, where hopes of photographing Comet A6 Lemmon met the familiar mix of excitement, haze, and grilled hamburgers under imperfect skies.Then we turn from backyard observing to deep-space communication with a hands-on look at the Arecibo Message — the radio transmission beamed from Earth in 1974 as humanity’s mathematical greeting to the stars. We’ll break down what that signal said, how it was constructed, and whether an alien civilization could ever decode its meaning. Along the way, Drew recreates the original 1,679-bit message using Python code, transforms it into sound, and decodes it again to reveal the famous stick figure, DNA helix, and planetary map.It’s a story about logic, language, and what it means to say hello to the universe — a reminder that every beam of light and burst of radio energy carries a trace of who we are.For more episodes and resources for backyard astronomers, visit www.startrails.show.

As Halloween approaches, we drift into one of astronomy’s most haunting questions: if life in the universe is so likely, where is everybody? This week, we explore the famous Fermi Paradox — from Enrico Fermi’s lunchroom question to Frank Drake’s mathematical quest for cosmic company.Along the way, we revisit humanity’s attempts to speak into the void — the Arecibo Message, the golden records aboard Voyager, and the global volunteer army of SETI@Home. We also consider the possibilities: is the eerie silence a warning, a mystery, or simply a distance too vast for even radio waves to cross?Plus, your night sky report for October 26 through November 1, 2025 — featuring a first-quarter Moon, Saturn and Jupiter shining bright, Mercury at greatest elongation, and a visit from Comet Lemmon.For more episodes and resources for backyard astronomers, visit www.startrails.show.

The veil between life and death is thin in late October, and not just on Earth. This week on Star Trails, we take a haunting journey through The Cosmic Graveyard, a place where dead suns still glow, galaxies devour one another, and the faint aftershocks of ancient explosions echo across time. From the slow cooling of white dwarfs to the bottomless depths of black holes, we explore the universe’s quietest afterlife.But before venturing into that darkness, the night sky itself offers reason to stay up late. The Orionid meteor shower peaks under a new moon, delivering pristine, moonless skies for deep-sky observing. Saturn still commands the early evening, Jupiter gleams after midnight, and the autumn constellations fill the heavens with galaxies, clusters, and nebulae ripe for exploration.Plus, a listener’s question sparks a timely detour into the strange beauty of black holes and the now-iconic image of a glowing ring surrounding a dark center. Is it art, or reality? We explain the physics behind those haunting visuals and how Einstein’s relativity sculpts light itself into the illusion we see.So settle in beneath the cooling autumn sky, and listen as we wander the universe’s silent necropolis, where every dying star leaves behind a spark, and even the ashes of creation still shimmer with light.Mentioned in this episode:What do black holes look like?
The nights are growing longer, the air is sharpening, and the Moon is finally stepping aside. In this week’s episode, we look to the skies from October 12th through the 18th, and discover a season in transition: Saturn still reigning in the south, Jupiter climbing before dawn, Venus returning to the morning sky, and the Orionid meteor shower quietly stirring to life. With the waning Moon, late-week skies will be perfect for deep-sky observing — from the Andromeda Galaxy to the Helix Nebula.Then, we step into a stranger realm: The House of a Thousand Mirrors.In this eerie cosmic funhouse, light bends, time folds, and a single distant galaxy can appear dozens of times across the sky. We explore the phenomenon of gravitational lensing — from the elegant Einstein Cross to the ghostly arcs of Abell clusters, and even a supernova that appeared twice in two different years. It’s astronomy that feels like science fiction, except it’s real.For more episodes and resources for backyard astronomers, visit www.startrails.show.

The Harvest Supermoon rises over crisp autumn nights as Saturn reigns in the southeast and Pegasus climbs the eastern sky. In this week’s episode of Star Trails, we examine the celestial highlights of October 5–11 — including lunar encounters with Saturn and the Pleiades, the Draconid meteor shower, and a check-in on interstellar Comet 3I/ATLAS.Then, as the night deepens, we open the cosmic case files: five enduring unsolved mysteries of the universe. From the invisible grip of dark matter to the baffling Hubble tension, these are the riddles that defy physics and haunt the night sky.Whether you’re observing from your backyard or just viewing the stars in your imagination, this episode blends practical stargazing with spine-tingling cosmic intrigue.For more episodes and resources for backyard astronomers, visit www.startrails.show.

It’s been a short break due to technical issues, travel, and life in general, but the show is far from gone. Thanks to everyone who wrote in asking about it — your messages mean the world.Here’s what’s happening in the night sky from September 28 – October 4:September 28: A waxing crescent Moon appears, climbing higher each evening.September 30: The Moon reaches first quarter, brightening the evening skies.Saturn is well placed for evening viewing, glowing steadily in the south.Jupiter rises late at night into the pre-dawn hours, a bright beacon in the east.It’s the quiet buildup before a busy October — meteor showers, conjunctions, and cosmic curiosities await.The next episode (October 5) will feature a special segment on the unsolved mysteries of the cosmos—from strange planetary tilts to unexplained cosmic signals. Think of it as an astronomy-flavored Unsolved Mysteries.Until then, clear skies!
This week we explore both the night sky and the cosmic tick-tock of time itself. The Moon waxes from half-lit to nearly full, while Saturn shines golden in Pisces with its razor-thin rings. Jupiter and Venus rule the morning skies, and the faint Aurigid meteors and Comet Lemmon make cameo appearances for early risers. In the second half of the show, we dive into the strange and fascinating world of “time in space.” From NASA engineers living on Martian sols with their custom-built Mars watches, to the Omega Speedmasters strapped to Apollo astronauts’ suits, to the atomic clocks aboard GPS satellites that literally rely on Einstein’s relativity to keep us from getting lost—this is a journey through the cosmic heartbeat that guides explorers and Earthlings alike.For more episodes and resources for backyard astronomers, visit www.startrails.show.

This week we head outward to the seventh planet, where the James Webb Space Telescope has revealed a brand-new moonlet orbiting Uranus. Barely six miles across, this tiny world is so small you could, in theory, walk around it in a single day. But is “walking” even possible when the surface gravity is only a whisper? We run the numbers and explore what it would feel like to live in such a micro-gravity landscape, where a careless jump could fling you into orbit.Back under Earth’s skies, the nights begin in darkness. The week opens with a fresh New Moon, offering deep-sky windows before the crescent brightens. Saturn dominates the evening hours, Venus and Jupiter rule the dawn, and the Aurigids meteor shower brings a chance of surprise streaks before sunrise. We’ll also shine a light on three quieter constellations — Lacerta the Lizard, Aquarius the Water-Bearer, and Capricornus the Sea Goat — exploring the lore behind their faint patterns and the clusters, doubles, and globulars tucked among their stars.From new moons both near and far, to the myths written across our own skies, this is a week for patient eyes, and a reminder of how scale and story intertwine in the universe.For more episodes and resources for backyard astronomers, visit www.startrails.show.

Under a rare seasonal Black Moon, this week’s sky rewards early risers and deep-sky wanderers alike. We start with a whisper-thin crescent slipping closer to the Sun each morning, then pivot to a dawn showcase where Mercury reaches greatest elongation while Venus and Jupiter stack higher above the horizon. On Tuesday and Wednesday a paper-thin crescent Moon joins the lineup—a perfect wide-field photo op—while evenings bring Saturn rising into prime viewing on its road to September opposition. With moonlight out of the way, scan the Milky Way for under-sung binocular treats: Delphinus the Dolphin, M11 (Wild Duck Cluster) in Scutum, and the Coathanger asterism in Vulpecula. You may even catch a few Perseid stragglers in the pre-dawn dark.In the second half, we widen the frame to reveal the Milky Way’s “hidden companions”—dozens, maybe hundreds, of ultra-faint dwarf galaxies quietly orbiting our own. We unpack why they’re so hard to see (surface brightness, not just brightness), how modern surveys like SDSS and DES ferret them out, and why they matter for big questions about dark matter, galaxy growth, and the “missing satellites” problem.Links in this episode:Sloan Digital Sky SurveyThe Dark Energy SurveyGaia SkyFor more episodes and resources for backyard astronomers, visit www.startrails.show.
