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.

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.

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.

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.

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.

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.

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!
