    #420: Moon Water & Nemesis: Unveiling Lunar Mysteries and Stellar Theories
    May 26 2024
    Join Andrew Dunkley and Professor Fred Watson for another riveting Q&A edition of Space Nuts. This episode dives into some fascinating listener questions that challenge our understanding of space and science.First up, Mikey from Illinois poses a thought-provoking question: Can we drink water from the moon or Mars? Andrew and Fred explore the potential risks and benefits of consuming extraterrestrial water, including the presence of unknown substances and the impact of heavy water isotopes.Next, Sean from Nottingham inquires about the Nemesis theory, asking whether there could be a small sun or neutron star in our solar system, possibly linked to the elusive Planet Nine. Fred delves into the history and current standing of this hypothesis, examining its implications for mass extinctions and the structure of our solar system.Finally, Rusty from Donnybrook raises a question about the Hubble constant and whether the interstellar medium might be affecting the measurements of standard candles, leading to discrepancies in the universe's expansion rate. Fred explains the intricacies of this cosmic conundrum and why astronomers have considered and largely ruled out this possibility.

    From the safety of lunar water to the mysteries of distant stars and the expanding universe, this episode of Space Nuts promises to ignite your curiosity and expand your cosmic knowledge. Tune in and join the conversation!

  • #419: Blue Horizons & Fairy Floss Planets: Unveiling the Universe's Softest Secrets

    #419: Blue Horizons & Fairy Floss Planets: Unveiling the Universe's Softest Secrets
    May 23 2024
    Embark on a celestial journey with Andrew Dunkley and Professor Fred Watson in this episode of Space Nuts, where they explore a variety of space phenomena that are as intriguing as they are mysterious. Firstly, they discuss Blue Origin's return to the stars with NS-25, a mission that marked a triumphant comeback after technical setbacks. The flight not only signifies Blue Origin's resilience but also the inspirational story of Ed Dwight, the first African-American astronaut candidate, who at 90 years old, set a record as the oldest person to reach space.Next, the conversation lightens with the discovery of a planet with the consistency of fairy floss, also known as cotton candy or candy floss. WASP-193b, a gas giant that defies the norms of density and composition, leaves astronomers scratching their heads. How does a planet become so 'fluffy'? What could it possibly be made of? These are the questions that Andrew and Fred ponder as they delve into the mysteries of planet formation.Lastly, the duo discusses the gravitational wave background in the universe, likening it to the cosmic microwave background radiation. They explore how pulsar timing arrays are providing new insights into the 'hiss' of gravitational waves created by countless cosmic events, offering a deeper understanding of the universe's dynamic fabric.From record-breaking astronauts to cotton candy planets and the cosmic symphony of gravitational waves, this episode of Space Nuts is packed with astronomical wonders that will leave you in awe. Tune in and let your curiosity soar to the farthest reaches of space.00:00:00 This is Space Nuts, where we talk astronomy and space science
    00:01:12 Professor Fred Watson discusses eating fairy floss with a moustache
    00:02:10 Bright flash in the sky over Europe turned out to be comet
    00:05:55 Ed Dwight was the first astronaut of colour to be selected by NASA
    00:10:10 This is a newly discovered planet, or newly identified planet
    00:17:14 Planet in orbit around red dwarf star 1200 light years away
    00:21:06 Fred: Some work is being done on background gravitational waves
    00:28:17 Fred Watson: People are fascinated by gravitational waves because of mystery

  • #418: From Cosmic Drag to Holographic Hype: Unraveling the Mysteries of Space Travel

    #418: From Cosmic Drag to Holographic Hype: Unraveling the Mysteries of Space Travel
    May 19 2024
    Prepare to have your mind stretched to the cosmic limits in this Q&A episode of Space Nuts. Andrew Dunkley and Professor Fred Watson answer a selection of thought-provoking questions sent in by our curious listeners, tackling the mysteries of light, the concept of a holographic universe, and the challenges of interstellar travel.
    First up, Alan from Medicine Hat, Canada, wonders how far light from an LED with one candle power can travel before it becomes undetectable by space telescopes. The duo discusses the persistence of light and the factors that influence our ability to observe its journey through the cosmos.
    Next, Charles probes the perplexing theory of a holographic universe, questioning whether our three-dimensional experience is merely a projection from a two-dimensional boundary. Andrew and Fred unravel the theoretical underpinnings of this mind-bending concept and its implications for our understanding of reality.
    The conversation then accelerates to relativistic speeds with Craig from sunny Merimbula, NSW, asking how fast a spacecraft must travel before encountering drag in the sparse medium of space. They also consider the potential hazards of high-speed collisions with cosmic dust and gas, pondering the aerodynamic and navigational challenges that would arise.
    From the eternal voyage of light to the enigmatic nature of our universe and the theoretical speed limits of space travel, this episode of Space Nuts is a cosmic conundrum of astronomical proportions. Tune in as Andrew and Fred navigate through the universe's most intriguing puzzles.
