    S27E140: Sagittarius A* Controversy, Titan's Methane Clues, and Ozone Recovery Insights
    Nov 20 2024
    SpaceTime Series 27 Episode 140
    *Revisiting the Milky Way's Black Hole Image
    A new study questions the accuracy of the first-ever image of Sagittarius A, the supermassive black hole at the centre of the Milky Way. Researchers suggest the image may not accurately represent its appearance, proposing a more elongated accretion disc instead of the ring-like structure previously released by the Event Horizon Telescope.
    *Methane in Titan's Crust
    Data from NASA's Cassini spacecraft indicates that Saturn's moon Titan may have a methane-rich crust up to 10 kilometres thick. This insulating layer could explain Titan's shallow impact craters and its methane-rich atmosphere, providing insights into its unique geological and atmospheric dynamics.
    *Updates on Earth's Ozone Hole
    NASA reports that the annual ozone hole over Antarctica was smaller this year, ranking as the seventh smallest since recovery efforts began. The ozone layer is on track to fully recover by 2066, thanks to international agreements curbing ozone-depleting chemicals.
    The Science Report
    Antarctic ice core samples suggest Earth has already surpassed a 1.5°C global temperature rise due to human-induced climate change. A study links outdoor lighting at night to increased Alzheimer's risk for those under 65. LED lights on surfboards could reduce shark attacks by mimicking natural camouflage. Nord's latest survey reveals continued use of weak passwords, with "123456" and "password" among the most common.

  • S27E139: Australia's Rocket Renaissance, Cosmic Giants Unveiled, and Martian Ocean Mysteries

    S27E139: Australia's Rocket Renaissance, Cosmic Giants Unveiled, and Martian Ocean Mysteries
    Nov 18 2024
    SpaceTime Series 27 Episode 139
    *Gilmore Space Cleared for Orbital Launch
    The Australian Space Agency has granted Gilmore Space the final approval needed to conduct its maiden orbital test flight of the Ares rocket from the Bowen Spaceport in North Queensland. This launch will mark the first orbital test flight of an Australian-made rocket from Australian soil, showcasing a new hybrid propulsion system developed by the company.
    *Discovery of Red Monster Galaxies in the Early Universe
    Astronomers have identified three ultra-massive galaxies, each nearly the size of the Milky Way, that reached their colossal size within the first billion years of the universe's existence. These findings, reported in Nature, challenge existing models of galaxy formation and suggest a more efficient star formation process in the early universe.
    *Signs of an Ancient Martian Ocean
    China's Mars rover, Zhurong, may have found evidence supporting the theory that Mars' northern hemisphere was once covered by a vast ocean. The terrain around Zhurong's landing site includes features that could indicate past water or ice activity, suggesting a Martian ocean existed billions of years ago.
    The Science Robert
    Archaeologists in Israel have uncovered 12,000-year-old pebbles that may be precursors to the wheel, potentially pivotal in the evolution of rotating technologies. Meanwhile, the COP 29 climate summit highlights the ongoing rise in fossil emissions, with China remaining the largest polluter. Additionally, a study finds that frequent snoring in tweens is linked to behavioural issues, and a lack of conceptual clarity may explain beliefs in the paranormal.

  • S27E138: Outer Solar Mysteries, Australia's Orbital Leap, and Lunar Suit Innovations

    S27E138: Outer Solar Mysteries, Australia's Orbital Leap, and Lunar Suit Innovations
    Nov 15 2024
    SpaceTime Series 27 Episode 138
    *Discovery of the Outer Solar System's Magnetic Field
    Scientists have discovered evidence of an ancient magnetic field at the far reaches of our solar system. Research published in AGU Advances, based on 4.6 billion-year-old grain samples from the asteroid Richie, suggests the presence of a weak magnetic field during the formation of the outer solar system. This field, although weak, could have been instrumental in the formation of the outer planets, including Jupiter, Saturn, Uranus, and Neptune. The findings provide new insights into the magnetic influences shaping our solar system.
    *Southern Launch Gets Green Light for Orbital Missions
    Southern Launch has received federal and state government approval for its Whalers Way orbital launch complex in South Australia. The site is poised to support up to 42 orbital rocket launches annually, with plans for multiple launch pads and comprehensive tracking facilities. This development marks a significant step forward for Australia's growing Space industry.
    *Axiom Unveils New Lunar Spacesuits for NASA
    Axiom Space has revealed the new spacesuits for NASA's Artemis 3 mission, set for a lunar landing in 2026. Designed to withstand the harsh lunar environment, these suits feature improved mobility and dust resistance. The new design includes interchangeable segments to accommodate various body types, reflecting advancements in spacesuit technology since the Apollo era.
    The Science Robert
    A study has identified a decline in low-pressure weather systems, crucial for rainfall in southern Australia, since the mid-20th century. Meanwhile, the largest study of brain volume to date has found genetic links between ADHD and Parkinson's disease. In wildlife news, taming wild elephant calves has been shown to increase stress levels, potentially affecting their health. Finally, the paranormal world is abuzz with sightings of Robin Hood's ghost in Sherwood Forest, though sceptics remain unconvinced.
