• Astrophiz 232: Aurora Secrets & Solar Storms with Dr. Maria-Theresia Walach
    Apr 12 2026
    Ever wonder why that "dancing" Mother’s Day solar storm of May 2024 looked so different in photos than it did to the naked eye? 🌌 🔗 Full Transcript & Show Notes: https://astrophiz.com/2026/04/15/episode-232-maria-theresia-walach/ In this episode of Astrophiz, Dr. Maria-Theresia Walach—a leading space plasma physicist and researcher at Lancaster University—deconstructs the complex physics of the auroral oval with remarkable clarity. We go behind the lens to uncover the secrets of the colours we see, from dominant oxygen green to rarer nitrogen-induced magenta curtains. As we pass the peak of the Sun’s 11-year cycle, Maria-Theresia explains the vital role of magnetometers in forecasting and the fascinating biological reasons why digital sensors often "see" what our own eyes miss. In this episode, we explore: Space Weather Secrets: The science behind the massive May 2024 geomagnetic storm. The SMILE Mission: An inside look at the upcoming Solar Wind Magnetosphere-Ionosphere Link Explorer (a joint ESA and Chinese Academy of Sciences project). Big Data in Space: Navigating the challenges of ionospheric convection research. The Human Element: Why diversity and curiosity are the true engines of modern astrophysics.

    Aug 3 2026
    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.

  • Solar Fireworks: Inside the Sun with Dr. Laura Hayes (ESA)
    Jan 14 2026
    Dr. Laura Hayes (ESA) joins us to reveal the explosive physics of "Solar Fireworks." Discover how the Solar Orbiter is capturing the closest-ever images of our Sun. The Solar Cycle: Why we are heading toward a Solar Maximum. ESA Solar Orbiter: Insights from the front lines of heliophysics. Space Weather: How CMEs impact Earth’s technology. Dr Laura Hayes’ research focuses on solar flares, coronal mass ejections (CMEs), and space weather—phenomena that can disrupt satellites, communications, power grids, and create auroras. Using data from ESA’s Solar Orbiter mission, she studies how magnetic energy is stored and explosively released in the Sun’s atmosphere, why some flares produce CMEs, and how tiny, fast-evolving structures may drive flare energy release and coronal heating. Key Takeaways from Episode 226 Decoding the Solar Cycle: Dr. Laura Hayes explains why the Sun is currently reaching its "Solar Maximum" and what these frequent "Solar Fireworks" mean for Earth. Inside the ESA Solar Orbiter Mission: A behind-the-scenes look at how this cutting-edge spacecraft captures the closest-ever images of the Sun and its mysterious polar regions. The Science of Solar Flares & CMEs: Understand the physics behind Coronal Mass Ejections (CMEs) and how scientists track these massive bursts of solar plasma across the solar system. Space Weather Impacts: Discover how solar activity affects our satellites, GPS, and power grids, and why predicting "space weather" has become a global priority. Laura highlights the collaborative nature of solar physics, the importance of mentors and community, and the challenges facing early-career researchers. Hayes is also passionate about public outreach, emphasising the value of sharing publicly funded science and inspiring future scientists during what she calls a “golden age” of solar research. Dr Laura Hayes, an eminent Irish solar physicist and research fellow at the Dublin Institute for Advanced Studies, discusses her career path, scientific motivations, and cutting-edge research on our closest star. Growing up in coastal Ireland, Laura developed an early love of maths and physics driven by curiosity and problem-solving rather than a clear plan to become an astrophysicist. University research opportunities led her into solar physics, followed by a PhD at Trinity College Dublin and international postdoctoral work in the US and Europe.

    Nov 12 2025
    Are "leaky" satellites drowning out the early universe? 🛰️ Dr. Dylan Grigg (Curtin University/ICRAR) joins Astrophiz to reveal groundbreaking research into Unintended Electromagnetic Radiation (UEMR). As satellite constellations like Starlink proliferate, their electronic "noise" is leaking into protected radio astronomy bands. In this episode, we explore: 76 Million Images: How Dr. Grigg isolated satellite signals from the Murchison Radio-astronomy Observatory. The SKA-Low Connection: Why the Square Kilometre Array is at risk from these "noisy" neighbours. The Epoch of Reionization: What happens when satellite interference masks the faint signals from the first stars. The Regulatory Frontier: The urgent need for new international spectrum management. Guest Bio: Dr. Dylan Grigg is a researcher at Curtin University and ICRAR, specializing in radio frequency interference and its impact on deep-space observation.
