  • Cosmic Webs and Dark Energy: A New Model for the Universe

    Cosmic Webs and Dark Energy: A New Model for the Universe
    Sep 22 2025
    In this episode of SpaceTime, we tackle the mysteries of the cosmos with a new mathematical model of the universe and ponder the age-old question: are we alone in the universe?
    New Model of the Universe
    Scientists have unveiled a groundbreaking mathematical model aimed at simplifying our understanding of the universe's evolution over the past 13.8 billion years. This innovative research, based on data from the Dark Energy Spectroscopic Instrument (DESI), offers fresh insights into the cosmic web's structure, revealing how dark energy influences cosmic expansion. Lead author Leonardo Gianni from the University of Queensland discusses how this model challenges existing paradigms and provides a clearer picture of the universe's complex behaviour, including the impact of voids and collapsing regions of matter.
    Are We Alone?
    A new study presented at the European Planetary Science Congress raises intriguing questions about the existence of intelligent alien civilizations. Researchers estimate that the nearest technological society in our galaxy could be over 33,000 light years away, with conditions on their home planets potentially mirroring those of Earth. The study highlights the challenges of sustaining advanced life and the long timelines required for such civilizations to coexist with humanity.
    Partial Solar Eclipse
    Today, a partial solar eclipse graced the skies over New Zealand, the South Pacific, and parts of Australia and Antarctica. As the Moon passed between the Earth and the Sun, observers witnessed a stunning celestial display with up to 70% of the Sun's face obscured. This remarkable event serves as a reminder of the intricate dance of celestial bodies that shape our night sky.

  • Galactic Jets and Black Hole Explosions: Unveiling Cosmic Mysteries

    Galactic Jets and Black Hole Explosions: Unveiling Cosmic Mysteries
    Sep 19 2025
    In this episode of SpaceTime, we explore the thrilling prospects of observing exploding black holes, an astonishing stellar jet on the outskirts of the Milky Way, and the meticulous preparations for an Earth observation satellite mission.
    Exploding Black Holes on the Horizon
    A groundbreaking study suggests that astronomers may soon witness a black hole explosion, an event theorised to occur once every 100,000 years. Researchers now believe there’s a 90% chance of observing such an explosion within the next decade, potentially revealing primordial black holes formed shortly after the Big Bang. These explosions could provide a comprehensive catalogue of all subatomic particles, including those yet to be discovered, fundamentally altering our understanding of the universe's origins.
    Immense Stellar Jet Discovered
    Astronomers have identified a colossal stellar jet erupting from a young star in the Milky Way's outskirts, specifically in the Sharpless 2284 region. This rare phenomenon involves twin jets of hot plasma extending over eight light years, driven by superheated gases falling onto the massive star. Captured by NASA's Webb Space Telescope, this discovery not only sheds light on star formation but also offers insights into the conditions of the early universe.
    Preparing for Earth Observation
    The European Space Agency is conducting rigorous tests for a future Earth observation satellite mission, including an airborne campaign in the Arctic. Scientists are evaluating a new imaging microwave radiometer designed to monitor sea ice and its evolution. This mission aims to gather vital data on climate change and the Arctic environment, contributing to a better understanding of global phenomena.

  • Earth's Metal Recipe: Tectonics and the Supercontinent Split

    Earth's Metal Recipe: Tectonics and the Supercontinent Split
    Sep 17 2025
    In this episode of SpaceTime, we uncover the secrets of ancient geology, explore the watery past of an asteroid, and delve into the origins of globular clusters.
    Supercontinent Breakup Revealed
    Scientists have made significant strides in understanding the breakup of the supercontinent Rodinia, which occurred over 800 million years ago. Research conducted on rare minerals in Outback Australia has revealed how niobium-rich carbonatites rose through fault zones during tectonic rifting, providing insights into the geological processes that shaped our planet. These findings not only illuminate the history of Rodinia but also highlight the importance of niobium in modern technologies, such as electric vehicles and advanced alloys.
    Water Activity on Asteroid Richie
    Exciting new research confirms that liquid water once flowed on the parent body of the near-Earth asteroid Richie, challenging previous assumptions about water activity on asteroids. Analysis of rock samples returned by Japan's Hayabusa2 mission has shown evidence of water movement through Ryugu's rocks, indicating that carbon-rich asteroids may have played a more significant role in delivering water to Earth than previously thought. This discovery has profound implications for our understanding of planetary formation and the conditions that made Earth habitable.
    Origins of Globular Clusters
    Astronomers are closer to solving the mystery of globular clusters, dense stellar systems that have puzzled scientists for centuries. Recent high-resolution computer simulations have revealed multiple pathways for their formation, suggesting that some may originate from satellite dwarf galaxies stripped of their outer stars during galactic mergers. This breakthrough could lead to new insights into dark matter and the formation of the universe's earliest stars.
