    Pluto-Charon Impact Insights, BepiColombo's Final Flyby, and the Year in Astronomy: S28E06
    Jan 14 2025
    SpaceTime Series 28 Episode 06Formation of Pluto-Charon Binary SystemA new study reveals that the formation of the Pluto-Charon dwarf planet binary system may mirror that of the Earth-Moon system. The research, published in Nature Geoscience, suggests that both systems feature a secondary body significantly large in comparison to the primary, unlike other moons in our solar system. The findings could explain Pluto's active geology and potential subsurface ocean, highlighting the significance of giant impacts in shaping planetary bodies.BepiColombo's Final Mercury FlybyThe BepiColombo spacecraft has completed its final close flyby of Mercury, passing just 295 kilometres above the planet's surface. This manoeuvre marks the last gravity assist required for the joint ESA and JAXA mission before it enters Mercury's orbit in late 2026. The mission aims to study Mercury's magnetic field, surface composition, and interaction with the solar wind, enhancing our understanding of planets close to their host stars.Astronomy Highlights for 20252025 promises exciting astronomical events, with the Sun's solar cycle nearing its peak. Highlights include a rare edge-on view of Saturn's rings, potential brightening of comet G3 Atlas, and two lunar eclipses. The year also features significant planetary alignments, meteor showers, and opportunities to observe the Southern Cross and the centre of the Milky Way. Dr. Nick Glom provides insights into these celestial events and more.00:00 This is space Time Series 28, Episode 6 for broadcast on 13 January 202500:27 A new study suggests the formation of the Pluto Charon dwarf planet binary system04:35 BepiColombo spacecraft makes its final flyby of Mercury09:27 This is space time.

  • Mars' Volcanic Awakening, Supernova 1987A's Secrets, and Dream Chaser Delays: S28E05

    Mars' Volcanic Awakening, Supernova 1987A's Secrets, and Dream Chaser Delays: S28E05
    Jan 10 2025
    SpaceTime Series 28 Episode 05
    Volcanic Activity on Mars
    New research suggests recent volcanic activity on Mars, with eruptions possibly occurring within the last 50,000 years. This discovery, based on satellite observations, highlights a mysterious dark deposit in Elysium Planitia, indicating explosive volcanism. The findings could mean Mars is still volcanically active, raising possibilities of habitable conditions due to interactions between magma and icy substrates.
    Mysteries of Supernova 1987A
    Astronomers using the Murchison Wide Field Array have been delving into the enigmatic Supernova 1987A. The supernova, marking the death of a blue supergiant star, offers insights into stellar evolution. The peculiar hourglass shape and the unexpected blue supergiant phase of the progenitor star continue to puzzle scientists.
    Dream Chaser Space Plane Launch Delayed
    The inaugural flight of the Dream Chaser space plane, Tenacity, is now scheduled for May. The spacecraft will carry supplies to the International Space Station, showcasing its capabilities. Sierra Space plans to use Dream Chaser for future missions, including building an orbiting habitat.
    00:00 New study claims there's evidence for recent volcanic activity on Mars
    05:34 Low frequency radio observations have provided a window into SN 1987A's past life

  • Challenging Dark Energy, Solar Wind Mysteries, and Venus's Volcanic Past: S28E04

    Challenging Dark Energy, Solar Wind Mysteries, and Venus's Volcanic Past: S28E04
    Jan 8 2025
    SpaceTime Series 28 Episode 04
    Challenging the Existence of Dark Energy
    A groundbreaking study from the University of Canterbury in New Zealand is challenging the long-held belief in dark energy, suggesting that the universe's expansion might not require this enigmatic force. The research proposes the "timescape" model, which accounts for variations in cosmic expansion rates by considering differences in gravitational time dilation. This model could potentially resolve some of the universe's biggest mysteries, including the Hubble tension, by suggesting that dark energy is simply a misinterpretation of cosmic conditions.
    Solar Wind Slowing Beyond Pluto
    NASA's New Horizons spacecraft has detected a slowdown in the solar wind as it travels beyond Pluto. The data reveals that the solar wind, a stream of charged particles from the Sun, decelerates as it picks up interstellar material. This discovery offers new insights into the heliosphere's outer reaches and the interaction between solar and interstellar forces.
    Venus's Volcanic Past
    New research indicates that Venus's ancient tesserae regions, once thought to be akin to Earth's continental crust, may actually be composed of layered volcanic rocks. This finding, based on radar data from NASA's Magellan mission, challenges previous assumptions and provides fresh perspectives on Venus's geological history.
