Star Trails: A Weekly Astronomy Podcast

This week we take a look at the night sky from July 13th to the 19th, highlighting a waning Moon, brilliant morning planets, and the first whispers of the Perseid meteor shower.

We’ll check in on Venus dancing near the Pleiades, Saturn’s steady climb toward opposition, and Jupiter’s quiet return to the predawn sky. You’ll also hear what deep-sky targets are best viewed under the darkening moonlight—like the Dumbbell Nebula, Ring Nebula, and the Milky Way’s glowing heart through Sagittarius.

Later, we flip the telescope around and ask: What does Earth l...

This week we kick things off with a deceptively simple listener question: What exactly is mass? From beach balls to black holes, we explore how mass shapes the universe, and our understanding of gravity.

Then we turn our eyes to the night sky, where the Full Buck Moon rises low on the horizon, showing off the inspiring Moon Illusion. We’ll cover what planets are visible, what to look for in the coming nights, and keep in mind, meteor shower season is right around the corner.

Finally, we journey to the outermost reaches of the so...

own. Highlights include a close encounter between the Moon and Mars, a subtle meteor shower, and a dazzling pre-dawn lineup of planets.

In the second half of the show, we check out some of the most fascinating space news of the season, including:

Then, we zoom in on the Vera C. Rubin Observatory, which just re...

This week we explore one of the darkest, and most dynamic, weeks of the season for stargazing. With a New Moon on June 25th, we get a prime window to explore the deep sky, from the glowing heart of the Milky Way to the subtle shimmer of noctilucent clouds and the unpredictable June Bootids meteor shower.

There’s also a stunning series of planetary pairings, including Venus and the Moon at dawn, and a twilight dance featuring Mercury, Mars, and Regulus. Plus, we preview a lunar occultation of Mars and offer tips for timing the event in yo...

The week of June 15th to the 21st includes a waning Moon approaching perigee, a lineup of bright planets at both dusk and dawn, and the breathtaking rise of the Milky Way’s galactic core in the southeastern night sky.

But we’re also turning back the celestial clock. To honor the summer solstice on June 21st, the longest day of the year. We’ll explore how ancient cultures around the world used the sky to tell time, navigate, worship, and survive. From Stonehenge’s solar alignment to the jaw-dropping mechanics of the Antikythera device, we’ll journey th...

This week there’s a sky full of surprises. From the lowest full moon in nearly two decades—the golden-hued Strawberry Moon—to the elusive Arietid meteor shower peaking in broad daylight, there’s a lot to see… or at least know is happening above.

We’ll also track the current planetary lineup, including Mercury’s brief appearance next to Jupiter and some early morning views of Venus and Saturn. Then, in the second half, we shift our focus to the Sun, which is ramping up toward solar maximum.

We’ll explore the Sun’s 11-year magnetic cyc...

As June begins, the night sky greets stargazers with a blend of familiar favorites. This week we highlight a picturesque conjunction between Mars and the crescent moon, and Venus shines brightly as the Morning Star. Saturn lingers low in the early morning hours, and the Summer Triangle begins to dominate the eastern sky, signaling the slow approach of summer nights.

We take a look at some of the action around the Galactic Core, home to deep sky gems like the Lagoon and Trifid Nebulae, and the supermassive black hole known as Sagittarius A*, before taking a detour...

This week the New Moon arrives—perfect conditions for spotting deep-sky wonders. Discover five must-see celestial objects to track down while the skies are dark, from ancient globular clusters to swirling galaxies.

Then, we dig into a colorful cosmic mystery: why do we see red, blue, and yellow stars—but never green ones? We explain how star temperatures and light spectra play a role in the colors we perceive in the night sky.

It’s a shorter episode this week (Drew’s voice is a bit under the weather), but there’s still plenty to marvel at...

As the Moon wanes and the morning planets take center stage, we turn our gaze to a part of the sky rarely discussed on Star Trails: the Southern Hemisphere. In this episode, we take a journey through time and space to uncover the story of Argo Navis, the largest constellation that no longer exists.

We explore the celestial ship’s breakup into Carina, Vela, and Puppis, and dive into the nebulae, star clusters, and pulsars that remain in its wake. Along the way, we also meet a few other retired constellations, including a long-lost housecat named Felis.

In this week’s episode we’re chasing mysteries in all directions — from the icy edges of our solar system to the fiery hearts of dying stars.

First, we explore the renewed buzz around Planet Nine, the theoretical ninth planet that may be lurking far beyond Pluto. New infrared data from decades-old space telescopes has astronomers wondering if we’ve finally glimpsed this long-suspected giant — or perhaps something even stranger.

Then, it’s time to bask in the glow of May’s Flower Moon and spot a planetary conjunction in the early morning sky. We’ll also check in...

This week we start with the waxing Moon as it heads toward May’s micromoon, the Flower Moon. Jupiter and Mars light up the western sky, while Venus, Saturn, and elusive Mercury put on a show before sunrise.

Don’t miss your chance to spot Vesta — one of the brightest and biggest asteroids visible from Earth — as it reaches peak visibility this week.

Later in the show, we venture far beyond our solar system to explore the wild world of exoplanets: planets orbiting other stars. From glass rainstorms to twin-star systems, we take a look at the s...

This week we say goodbye to Comet SWAN as it disintegrates on its first — and last — visit to the inner solar system. With a New Moon offering ideal stargazing conditions, we turn our attention to the Summer Triangle, Venus and Saturn’s pre-dawn pairing, and Mars dances near the Beehive Cluster.

In the second half, we spotlight the galaxy’s rebellious loners: runaway stars. From the aftermath of supernovas to gravitational billiards near black holes, discover how some stars break free and speed through space at hundreds of kilometers per second. We’ll explore how they’re formed, how...

Not every week is packed with drama in the skies, but that doesn’t mean it’s empty! This short episode covers the best of what is happening: the Lyrids peaking, a rare comet making an appearance, and a graceful planetary alignment to catch before sunrise.

In this episode we explore the night sky from March 23-29, highlighting the waning crescent moon, a lineup of bright planets, and an upcoming partial solar eclipse—though not everyone will get a chance to see it.

This week, we also take a look at two constellations that mark the arrival of spring: Virgo and Cancer. From galaxy clusters in Virgo to the Beehive Cluster in Cancer, there’s plenty to discover with just a small telescope or binoculars.

Also, the biggest mystery of the cosmos takes center stage as we revisit one of the grea...

The night sky is shifting this week as Venus and Mercury take their leave from the evening sky—at least for now. Jupiter shines in Taurus, Mars lingers near Gemini’s twin stars, and Leo rises high, showcasing its dazzling triplet of galaxies.

Speaking of cosmic wonders, a listener wrote in with a great question: Why do astronomers say “water ice” instead of just “ice”? We break it down, from Martian polar caps to the frozen landscapes of Europa and Enceladus.

Then, we take a look at the Pleiades, a stunning open star cluster best viewed with...

A total lunar eclipse is on the way! This week, the Worm Moon will turn a deep red as Earth’s shadow completely covers it. We break down when and where to watch this Blood Moon on the night of March 13–14, plus the science behind its eerie glow.

Drew shares tips on spotting Mercury just after sunset and why Venus is still stealing the evening show. We’ll also discuss Daylight Saving Time’s impact on stargazing and how to adjust your obser...

This week on Star Trails, we explore the fascinating world of space rocks—asteroids, comets, and meteors—and their impact on our planet and beyond. With recent talk of asteroid 2024 YR4 making headlines (don’t worry, it won’t hit us!), we break down what these celestial objects are, where they come from, and what makes them so important to study.

We'll also take a look at the Tunguska and Chelyabinsk meteor events, the impact that wiped out the dinosaurs, and the Shoemaker-Levy 9 collision with Jupiter—real-life cosmic events that shaped our understanding of space hazards.

Plus, we...
