    Astrophiz #240: Trevor Barry — The Outback Astronomer | NASA-Grade Planetary Data From a Backyard Observatory

    Trevor Barry — the Outback Astronomer — is a world-renowned planetary imager whose backyard observatory in Broken Hill, NSW, produces scientific-grade Jupiter and Saturn data used by NASA. In this episode of Astrophiz, host Brendan O'Brien travels to the outback to sit down with Trevor at his custom-built observatory. Discover how a former mining tradesman built a 16-inch high-resolution planetary telescope with a 32-point mirror cell and Peltier-cooled optics — and why Broken Hill's flat outback terrain produces some of the best planetary seeing on Earth. From tracking Saturn's electrical storms for NASA's Cassini mission to winning the ASA Berenice and Arthur Page Medal and ALPO's Walter H. Haas Award, Trevor breaks down the exact capture, derotation and processing workflow behind his NASA-grade data. IN THIS EPISODE: -Introduction: Arriving in Broken Hill - From the Mines to the Night Sky: the "aha" moment - Building the First Telescope: storm water pipe & a trip into the roses - Why Broken Hill Delivers World-Class Seeing - Inside the Observatory: the 32-point mirror cell & Peltier-cooled optics - First Contact with NASA: discovering an electrical storm on Saturn - From Pretty Pictures to Scientific Data: capture & processing protocols - The Thrill of Discovery: Jupiter's real-time impact scar - A Dream Fulfilled: two nights on the twin Keck telescopes, Mauna Kea - Mission Control at JPL: meeting Dr Carolyn Porco - Advice for Amateurs: where to send your data - Earning Trust in the Professional Community - Looking Ahead: the 2028 total solar eclipse & Saturn's Great Vortex - The Golden Mic: sharing the wonder with the next generation Full transcript & images: https://astrophiz.com Trevor's book "Outback Astronomer": available online & in all good bookstores Trevor's 60 Minutes feature: tinyurl.com/trevorbarry Astrophiz is an independent, ad-free science podcast running since 2016.

    Galaxy Forensics: Decoding Galaxy Evolution with Dr. Elisabete da Cunha (Astrophiz 230)

    How do we "autopsy" a galaxy from billions of light-years away? Join world-renowned astrophysicist Dr. Elisabete da Cunha as she sits down with Astrophiz host Brendan O’Brien to explore the life, evolution, and eventual "death" of the most massive structures in the universe. From her early inspirations under the stars of Portugal to her groundbreaking work in Extragalactic Astronomy, Elisabete shares her personal journey and the high-tech tools used to decode Starlight, Cosmic Dust, and Spectral Energy Distributions (SEDs). In this episode, we dive into: Galaxy Evolution: How star systems grow and transform over billions of years. Radio Astronomy: Using invisible light to peer into the deep universe. Stellar Populations: What the chemistry of stars tells us about the history of space. Cosmology & Dark Matter: The invisible forces shaping our galactic neighborhood. Whether you are a student of astrophysics or a casual stargazer, this conversation offers a unique, charming, and deeply insightful window into the forensic evidence of our universe.

    Astrophiz 239: August 2026 Sky Guide — Venus at Greatest Elongation, Mars Meets the Crab Nebula, and the Eagle of Aquila Dr. Ian 'Astroblog' Musgrave returns with your essential guide to the August night sky. This month the planetary action shifts to the morning sky, with Mars sweeping past the Crab Nebula and open cluster M35, while Saturn begins opening its rings ahead of September opposition. Venus dominates the evening twilight on its way to greatest elongation, and the Moon occults El Nath (Beta Tauri) on the 9th. In this episode: Moon Phases: Last Quarter, New Moon, First Quarter, Full Moon, and the Lunar X A Total Solar Eclipse crosses the Northern Hemisphere (not visible from Australia) Evening Skies: Venus approaches greatest elongation; Jupiter absent until next month Morning Skies: Mars passes the Crab Nebula and M35; Saturn's rings begin opening Deep-Sky Spotlight: Scorpius, Sagittarius, and the constellation Aquila the Eagle Indigenous Astronomy: Aquila in Koori, Boorong, and Muurrbay sky-lore The Occultation of Elnath by the Moon, August 9 The Perseid Meteor Shower (best from the Northern Hemisphere) The Tangent: How sugar and other organic molecules survive the birth of a new star Read the full transcript and see the show notes at: astrophiz.com Support independent science: Astrophiz is free, ad-free, and unsponsored. #Astrophiz #Astronomy #Stargazing #SciencePodcast #AugustSkyGuide #IanMusgrave #Venus #Mars #Saturn #Aquila #NightSky #Astrophotography

    Astrophiz 236: Dr Gabriela Ligeza – Driving the ExoMars Rosalind Franklin Rover & Mapping the Moon

    Welcome to Astrophiz! In this episode, host Brendan O'Brien sits down with the brilliant Dr. Gabriela Ligeza, an Internal Research Fellow at the European Space Agency (ESA) in the Netherlands. Dr. Ligeza works at the absolute cutting edge of planetary exploration, bridging the gap between orbital maps and physical alien terrain. As a key scientist for ESA’s ExoMars mission, she is developing the science sampling strategies that will guide the Rosalind Franklin rover in its high-stakes hunt for ancient morphological biosignatures (fossilized signs of microbial life) in the 4-billion-year-old clays of Oxia Planum. We also dive deep into her incredible work for NASA’s Artemis program at the Johnson Space Center, where she mapped the lunar South Pole to establish the landing and geological sampling sites for the next human footprints on the Moon. In this episode, we explore: • The childhood spark: How a postcard from a NASA astronaut geologist changed her life. • Martian lighting secrets: How light and shadow in the Mars Lab reveal (or hide) the true history of alien rocks through the CLUPI (Close-Up Imager) instrument. • Four-legged space dogs: Why autonomous legged robots can conquer steep crater rims and lava tubes where traditional wheeled rovers fail. • Training Astronauts: What it takes to teach pilots and engineers to think like field geologists on the lunar surface. • The mystery of Noachian iron/magnesium phyllosilicates—the ancient Martian mud that could hold the key to answering: Are we alone? Whether you are an aspiring researcher or a casual stargazer, Dr. Ligeza’s journey from a small village in Poland to the forefront of solar system exploration is profoundly inspiring.
