  • Interstellar Insights: Tracking Comet 3I/Atlas and the Ganon Superstorm's Impact on Earth

    Interstellar Insights: Tracking Comet 3I/Atlas and the Ganon Superstorm's Impact on Earth
    Nov 28 2025
    In this episode of SpaceTime, we delve into the latest discoveries and challenges in space exploration and Earth science.
    Tracking Interstellar Comet 3I Atlas from Mars
    The European Space Agency has successfully monitored interstellar comet 3I Atlas from its ExoMars Trace Gas Orbiter, significantly improving the accuracy of its predicted trajectory by a factor of ten. The comet, which travels at speeds of up to 250,000 km/h, was observed from a unique vantage point, allowing astronomers to refine its path through our solar system. This remarkable achievement underscores the importance of multi-location observations in planetary defense efforts.
    Geomagnetic Superstorm Ganon's Impact on Earth's Plasma Sphere
    A recent study reveals how the geomagnetic superstorm Ganon dramatically compressed Earth's plasmasphere, reducing its size to just a fifth of its normal extent. This event, which occurred in May 2024, provides crucial insights into the effects of extreme space weather on our planet's protective layers. The findings will enhance solar storm forecasts and help safeguard satellites and communication systems during such events.
    Delays for the Dream Chaser Spaceplane
    Sierra Space's Dream Chaser spaceplane faces further delays, now expected to launch its first orbital flight in approximately a year. Originally designed for crew transport, the spacecraft is now slated for resupply missions to the International Space Station. Despite setbacks, recent tests have demonstrated its systems' readiness for future operations, although challenges remain as the ISS's operational life nears its end.

    In this episode of SpaceTime, we uncover groundbreaking insights into Earth's mysteries and the cosmos beyond.
    Mysterious Structures in Earth's Mantle
    A new study reveals that enigmatic structures within Earth's mantle may hold vital clues about why our planet evolved the conditions necessary for life. These massive formations, known as large low shear velocity provinces and ultra low velocity zones, reside at the boundary between the mantle and outer core, approximately 2,900 kilometres beneath the surface. The research suggests these anomalies could be remnants of Earth's formative processes, providing a deeper understanding of how elements from the core influenced the planet's cooling, volcanic activity, and atmospheric evolution, ultimately setting Earth apart from Venus and Mars.
    Unprecedented View of the Milky Way
    Astronomers have achieved a remarkable new perspective of our home galaxy, the Milky Way, with the largest low-frequency radio image ever assembled. This extensive survey, conducted using the Murchison Wide Field Array radio telescope in Western Australia, captures the intricate birth, evolution, and demise of stars across the southern hemisphere. The new image, which boasts double the resolution and tenfold sensitivity compared to previous observations, offers valuable insights into stellar interactions and the cosmic landscape, revealing patterns in star formation and supernova remnants.
    Successful Return of Stranded Taikonauts
    In a significant development, the three Chinese taikonauts stranded in orbit after their Shenzhou 20 spacecraft was struck by space debris have safely returned to Earth aboard the Shenzhou 21 capsule. The crew's return marks the end of a six-month mission at the Tiangong space station, with their extended stay setting a new record for the longest duration in space for Chinese astronauts. The episode highlights the challenges of space travel and the rapid response by Beijing to ensure crew safety.
