Observers Notebook

Today I'm delighted to welcome two familiar voices in the amateur astronomy community: Chris and Shane, hosts of the Actual Astronomy Podcast. If you've spent any time searching for astronomy podcasts over the past several years, chances are you've come across Actual Astronomy Podcast. Week after week, Chris and Shane have built a loyal following by doing something refreshingly simple—they focus on getting people outside under the night sky. Their conversations are practical, engaging, and packed with observing tips, equipment advice, and firsthand experiences that inspire listeners to spend less time reading about astronomy and more time actually observing. Whether they're discussing the best telescope for a beginner, exploring overlooked deep-sky treasures, reviewing observing accessories, or sharing memorable nights under dark skies, their enthusiasm for visual observing shines through every episode. Today we'll learn how the podcast began, what keeps them motivated after hundreds of episodes, how amateur astronomy has evolved over the years, and where they see the hobby heading in the future. We'll also hear about some of their favorite telescopes, observing projects, and memorable experiences under the stars. So, whether you're a seasoned observer with decades behind the eyepiece or someone just beginning your astronomical journey, I think you're going to enjoy this conversation.

Episode 245 Welcome to The Observers Notebook, a production of the Association of Lunar and Planetary Observers. We often use a phrase within the ALPO: “From Stargazing to Science.” It describes a journey. Many of us begin simply by looking up at the night sky. Then we acquire a telescope. We begin observing more carefully. We learn to image, measure and document what we see. We share our observations with others. And sometimes those observations become something more. They become science. Today’s program may be one of the best examples of that journey I can imagine. Joining me from Broken Hill, Australia, is amateur astronomer Trevor Barry, a co-author of a newly published Science Advances paper reporting a remarkable discovery on Saturn: a previously unseen decagonal wave surrounding Saturn’s south pole. Trevor, congratulations—and welcome to The Observers Notebook.

Episode 244 Welcome everyone to another episode of the Observers Notebook Podcast. This episode is going to be a little different. Rather than talking about how to observe an astronomical object or interviewing someone about their work, I want to take you along on a very personal astronomy adventure—my week aboard Windstar’s Star Pride during the August 2026 total solar eclipse in Iceland. I’ve been fortunate enough to sail with Windstar many times—this was cruise number 27—but this cruise was completely different. For the first time, I wasn’t onboard simply as a passenger. I was there as a guest speaker and the ship’s eclipse expert, giving presentations, answering questions, working with the Captain and bridge crew, and helping prepare the passengers for what we hoped would be an incredible total solar eclipse at sea. And then, about an hour before the eclipse, Iceland reminded us who was really in charge. The fog rolled in. We didn't get the picture-perfect view of totality we had dreamed about. But what happened aboard the Star Pride when the Moon’s shadow reached us turned out to be something I will never forget. The sky dramatically darkened, the temperature plunged, and hundreds of passengers and crew members cheered together as we entered the shadow of the Moon. In this episode, I want to share what happened behind the scenes—the preparations, my conversations with the Captain, what it was like giving presentations aboard the ship, the eclipse itself, and some of the wonderful people we met along the way. I'll also be joined for a short conversation by fellow guest speaker Orly Orlyson, an Icelandic filmmaker, historian, and storyteller, who will tell us about his museum in Húsavík and the remarkable connection between this little Icelandic town, the movie Eurovision Song Contest: The Story of Fire Saga, and the Academy Awards. So pour yourself a cup of coffee—or, in true Windstar fashion, maybe a glass of wine—and come aboard the Star Pride with me as we head into the shadow of the Moon. Let’s get started.

Welcome to the Observers Notebook, the official podcast of the Association of Lunar & Planetary Observers—where we take you from Stargazing to Science. I'm your host, Tim Robertson. Every once in a generation, astronomy takes a giant leap forward. From Galileo's first telescope to the Hubble Space Telescope, new instruments have transformed the way we see and understand the universe. Today, we're witnessing another one of those moments. High atop Cerro Pachón in Chile stands the Vera C. Rubin Observatory, home to the largest digital camera ever built for astronomy. Over the next decade, this remarkable facility will image the entire southern sky every few nights, creating an unprecedented time-lapse record of our dynamic universe. It will discover millions of asteroids and comets, detect exploding stars, map billions of galaxies, help us better understand dark matter and dark energy, and alert astronomers around the world whenever something in the sky changes. But Rubin isn't just a telescope for professional astronomers. Its discoveries will open exciting new opportunities for amateur astronomers, educators, citizen scientists, and organizations like ALPO to participate in real scientific discovery. Joining me today is Clare Higgs from the Vera C. Rubin Observatory. Clare is helping share the story of this extraordinary project and its mission to transform our understanding of the cosmos. We'll talk about how the observatory works, the science it's designed to accomplish, what makes its 3.2-billion-pixel camera so revolutionary, and what exciting discoveries may lie just around the corner. Clare, welcome to the Observers Notebook. It's a pleasure to have you with us.

Episode 242 Welcome to The Observers Notebook, the official podcast of the Association of Lunar & Planetary Observers, where we connect you with the people, discoveries, and techniques that take us from stargazing to science. I'm your host, Tim Robertson. Whether you're a seasoned lunar observer, someone who simply enjoys looking up at the Moon, or you're introducing a child or grandchild to the night sky for the very first time, this episode is for you. Every year, hundreds of thousands of people around the world step outside on one special evening to celebrate our closest celestial neighbor during International Observe the Moon Night. It's a global event that reminds us that no matter where we live, we all share the same Moon. Joining me today is Staci Horvath, Outreach Lead for NASA's Solar System Exploration Division at NASA Goddard Space Flight Center and the director of International Observe the Moon Night. Staci has dedicated her career to helping people connect with the excitement of space exploration, making astronomy accessible, engaging, and inspiring for audiences of all ages. Today we'll talk about the origins of International Observe the Moon Night, why the Moon remains one of the best objects in the sky for beginning and experienced observers alike, how astronomy clubs and educators can host successful events, and how this worldwide celebration fits into NASA's exciting new era of lunar exploration through Artemis. We'll also discuss how amateur astronomers can contribute to lunar science, the resources NASA provides for observers and event organizers, and, of course, we'll get to know Staci a little better through some fun questions at the end of the show. So grab your favorite observing chair, dust off your telescope—or simply step outside and look up—as we celebrate the Moon and the people who inspire millions to observe it. Please join me in welcoming Staci Horvath to The Observers Notebook.

Episode 240 Welcome to another episode of The Observers Notebook, the official podcast of the Association of Lunar & Planetary Observers — where we explore the Solar System and beyond, from stargazing to science. I’m your host, Tim Robertson, and today we’re diving into one of the most fascinating questions humanity has ever asked: Are we alone in the universe? For centuries, humans have looked up at the night sky and wondered if somewhere out there, another civilization is doing the exact same thing — looking back toward us. Today’s guest is helping lead that search. Joining us is Franck Marchis — astronomer, planetary scientist, entrepreneur, and one of the leading voices in modern SETI research. Franck is known for his groundbreaking work in adaptive optics, asteroid systems, exoplanets, and the search for technosignatures — possible evidence of advanced civilizations elsewhere in the cosmos. He’s also deeply involved in the future of astronomy through innovative telescope networks, citizen science, and the development of new observational technologies that could dramatically expand our ability to detect life beyond Earth.

Welcome to another episode of The Observers Notebook, the official podcast of the Association of Lunar and Planetary Observers (ALPO), where we take you From Stargazing to Science. I'm your host, Tim Robertson, and today we're looking ahead to one of the year's most anticipated celestial events—the deep partial lunar eclipse occurring on the night of August 27–28, 2026. While this won't be a total lunar eclipse, nearly the entire Moon will pass through Earth's umbral shadow, creating a spectacular sight for observers across much of the world. It's an event that promises beautiful views through binoculars and telescopes, outstanding photographic opportunities, and, perhaps most importantly, a chance for amateur astronomers to make observations that have genuine scientific value. Joining me are two outstanding members of the ALPO team. First, we'll welcome John O'Neal, Coordinator of the ALPO Eclipse Section. John has spent decades observing and documenting eclipses and will walk us through exactly what we'll see during this eclipse, why this particular event is so special, and how you can make the most of your observing session, whether you're a first-time eclipse watcher or a seasoned veteran. Then we'll be joined by David Teske, Coordinator of ALPO's Lunar Section. David will introduce us to the fascinating world of crater contact timings—carefully timing when well-known lunar craters disappear into and emerge from Earth's shadow. It's a classic observing program that continues to provide valuable scientific data and is something nearly any telescope owner can participate in. So whether you're planning to simply step outside and enjoy one of nature's greatest spectacles, photograph the changing colors of the Moon, or contribute observations to the scientific community, this episode will help you prepare for eclipse night. So sit back, grab your favorite beverage, and let's talk about the August 27–28, 2026 Lunar Eclipse, here on The Observers Notebook.

Episode 239 What makes a telescope truly exceptional? Is it aperture… optics… craftsmanship… or something more? And in a time when technology is rapidly changing how we explore the night sky—from smart telescopes to AI-assisted imaging—where does the future of amateur astronomy really lie? Today, we’re going to explore that question with someone who has spent decades building precision instruments for observers who demand the very best. I’m excited to welcome Vic Maris, founder of Stellarvue—a company well known in the amateur astronomy community for producing high-quality refractors and precision optical systems. Vic has built Stellarvue around a philosophy that emphasizes craftsmanship, rigorous optical testing, and delivering instruments that meet the expectations of serious observers and imagers alike. In this episode, we’re going to talk about the story behind Stellarvue, what it takes to build premium telescopes in today’s market, and how advances in technology are reshaping the way we observe the night sky. We’ll also get Vic’s perspective on where amateur astronomy is headed—what excites him, what concerns him, and what advice he has for the next generation of observers. So sit back, relax, and enjoy my conversation with Vic Maris.

“From Stargazing to Science” feels like an anthem for the modern amateur astronomer — especially for the mission of the Association of Lunar & Planetary Observers. The song carries a cinematic, inspirational tone. It starts with the wonder of looking up at the night sky — telescopes in backyards, people gathered under stars, the excitement of seeing Saturn’s rings or the craters of the Moon for the first time. The early verses have a sense of curiosity and discovery, capturing the emotional side of astronomy: the awe, imagination, and personal connection to the cosmos. As the song builds, it transitions from simple observing into something deeper: contribution. The chorus represents the idea that everyday observers can become part of real scientific work. It celebrates how sketches, images, measurements, and observations made by amateurs can contribute to planetary science and the scientific record. That’s the heart of the phrase “From Stargazing to Science.”

Episode 238 Welcome to The Observers Notebook, the official podcast of the Association of Lunar & Planetary Observers — where we explore the Solar System and beyond, from Stargazing to Science. I’m your host, Tim Robertson, and today we’re diving into one of the best times of year for meteor observing — summertime meteor showers. Joining me is longtime meteor observer and expert Bob Lunsford. Bob has spent decades monitoring meteor activity and helping observers understand what’s happening in our skies each month. Tonight we’ll talk about the major summer meteor showers, what to expect this year, how to observe meteors effectively, and how amateurs can contribute meaningful scientific observations. If you enjoy meteor watching — or want to learn how to get started — this episode is for you.
