  • Cosmic Milestones: The Earliest Supernova and Martian Water Mysteries

    Cosmic Milestones: The Earliest Supernova and Martian Water Mysteries
    Dec 19 2025
    In this episode of SpaceTime, we uncover groundbreaking discoveries and exciting celestial events that illuminate our understanding of the universe.
    Earliest Supernova Ever Detected
    Astronomers have achieved a remarkable milestone by detecting the earliest supernova ever observed, dating back to a mere 730 million years after the Big Bang. Using the powerful Webb Space Telescope, this supernova, cataloged as GRB250314A, emitted a gamma ray burst that has shattered previous distance records. Lead author Andrew Levin shares insights into how this discovery provides a glimpse into the universe when it was only 5% of its current age, revealing surprising similarities with modern supernovae despite the vast differences in their epochs.
    Liquid Water on Mars: New Evidence
    New seismic data from NASA's Mars InSight lander suggests that liquid water could still exist beneath the Martian surface, potentially providing a habitat for microbial life. The analysis of marsquakes has revealed boundaries in the Martian crust that indicate the presence of water-filled cracks, offering compelling evidence that life may persist on the Red Planet. We discuss the implications of these findings and the methodologies used to analyze the Martian subsurface.
    The Great Geminids Meteor Shower of 2025
    The annual Geminid meteor shower is reaching its peak, presenting stargazers with the chance to witness up to 100 meteors per hour under optimal conditions. Unlike many meteor showers that originate from comets, the Geminids are unique as they come from the asteroid 3200 Phaethon. Dr. Robert Massey provides tips on how to best observe this spectacular celestial event, emphasizing the importance of dark skies and the naked eye for optimal viewing.

  • Gamma Ray Revolution: The Longest Burst and Cosmic Mysteries Unveiled

    Gamma Ray Revolution: The Longest Burst and Cosmic Mysteries Unveiled
    Dec 17 2025
    SpaceTime with Stuart Gary Gary - Series 28 Episode 147
    In this episode of SpaceTime, we delve into remarkable discoveries that significantly enhance our understanding of the cosmos.
    Longest Gamma Ray Burst Ever Detected
    Astronomers have made headlines with the discovery of the longest gamma ray burst ever recorded, GRB 250702B, which lasted over seven hours. This unprecedented event is reshaping our understanding of stellar explosions and their aftermath. Initial observations indicate that this extraordinary burst may have originated from a black hole consuming a star, prompting new theories about the mechanisms behind these powerful cosmic phenomena. We explore the implications of this finding and how it challenges existing models of gamma ray bursts.
    Elemental Bounty in Supernova Remnant
    For the first time, scientists have detected chlorine and potassium in the remnants of the supernova Cassiopeia A, utilizing the advanced capabilities of the CRISM spacecraft. This discovery sheds light on the elemental processes that occur during stellar explosions and their connection to the formation of elements crucial for life on Earth. We discuss the significance of these findings and their impact on our understanding of stellar nucleosynthesis.
    International Space Station Fully Occupied
    In a historic first, the International Space Station has reached full capacity, with all eight of its docking ports in use. We discuss the implications of this milestone, including the logistics of managing multiple spacecraft and the ongoing missions currently underway aboard the ISS.

  • MAVEN's Silence: Unravelling the Mystery of Mars' Lost Contact

    MAVEN's Silence: Unravelling the Mystery of Mars' Lost Contact
    Dec 16 2025
    In this episode of SpaceTime, we explore significant developments in space exploration and cosmic studies that could reshape our understanding of the universe.
    Nasa's MAVEN Mars Orbiter: Communication Loss
    NASA's MAVEN (Mars Atmosphere and Volatile Evolution) spacecraft has gone silent, with contact lost on December 6th after passing behind Mars. The orbiter has been a vital asset for over a decade, studying the Martian atmosphere and solar wind interactions that have transformed Mars from a water-rich world to a cold desert. We delve into MAVEN's critical findings, including the mechanisms of atmospheric escape and the implications of its potential loss for ongoing Martian research.
    Galactic Neighbourhoods: Influencing Evolution
    A new study reveals how a galaxy's local environment can significantly affect its evolution. The research, published in the Monthly Notices of the Royal Astronomical Society, demonstrates that galaxies situated in densely populated regions tend to grow more slowly and develop different structures compared to their isolated counterparts. By analysing data from the Deep Extragalactic Visible Legacy Survey, astronomers have gained insights into the complex dynamics of galactic interactions and their impact on star formation rates.
    Uranus and Neptune: More Richie than Icy?
    Challenging long-held classifications, a recent study suggests that the solar system's ice giants, Uranus and Neptune, may actually be more rocky than icy. Researchers from the University of Zurich conducted computer simulations that indicate a broader range of internal compositions for these planets, which could explain their complex magnetic fields. This new perspective could alter our understanding of planetary formation and evolution, paving the way for future explorations of these distant worlds.
