    Space Nuts: Mars’ Moons, Martian Quakes, and the Search for ET
    In this engaging episode of Space Nuts, Andrew Dunkley and Professor Fred Watson explore two mysteries from Mars, along with a new effort to listen for signs of life beyond Earth. First, they unpack Japan’s Martian Moons eXploration (MMX) mission, which will study Phobos and Deimos, attempt a landing on Phobos and bring samples back to Earth. The discussion turns to a Marsquake traced to the immense Valles Marineris canyon, offering fresh clues that the Red Planet may still be geologically active. Finally, Andrew and Fred Watson examine Saudi Arabia’s plans for a major astronomical observatory, including a site for Laser SETI detectors searching for brief flashes of possible extraterrestrial communication. Join them for a cosmic tour filled with planetary puzzles, ambitious missions and a little speculation about how aliens might get in touch.
    Key topics
    - Japan’s MMX mission to investigate Mars’ moons and return samples from Phobos.
    - The possible origins of Phobos and Deimos, and the challenges of landing on a world with almost no gravity.
    - A Marsquake linked to Valles Marineris and what it suggests about the planet’s geological activity.
    - Saudi Arabia’s planned observatory and the use of optical Laser SETI detectors in the search for extraterrestrial signals.

    Space Nuts: Ejected Stars, Black Hole Deaths, and Astronomy Resources
    In this engaging Q&A episode of Space Nuts, hosts Andrew Dunkley and Professor Fred Watson tackle a variety of intriguing questions from listeners. The episode kicks off with Clark from Auckland, who wonders about the possibility of stars and planets being ejected from galaxies, and what that means for rogue celestial bodies. Next, Scott from Hobart delves into the life cycle of black holes, asking what happens when they can no longer hold back light and how they ultimately meet their end. Rusty from Brooklyn poses a thought-provoking hypothetical scenario about the sun disappearing and its effects on Earth's gravitational tether. Finally, Bea from Sydney seeks advice on resources for beginners in astronomy, prompting a discussion on apps, books, and equipment to kickstart a cosmic journey. Join Andrew and Fred Watson as they explore these cosmic curiosities with their signature blend of wit and insight.
