SpaceTime with Stuart Gary

SpaceTime Series 27 Episode 142*How Mars Got Its MoonsA groundbreaking study suggests that Mars acquired its moons, Phobos and Deimos, after a passing asteroid was torn apart by the planet's gravity. This new hypothesis, based on NASA's supercomputer simulations and published in the journal Icarus, challenges previous theories of their origin, such as capture or major impact. The upcoming Martian Moons Exploration mission by JAXA, with NASA's involvement, aims to further investigate these theories by collecting samples from Phobos.*Starship Test Flight 6SpaceX has successfully completed its sixth test flight of the Starship Mega rocket, overseen by SpaceX CEO Elon Musk and U.S. President-elect Donald Trump. The test included a splashdown of the booster in the Gulf of Mexico and a successful orbital journey of the Starship, which trialled new heat shield materials and descent strategies. This marks the final test for this version of Starship, with an upgraded version expected to fly soon.*Revisiting Earth's Ore DepositsNew research reveals that the largest iron ore deposits in Western Australia's Pilbara are around a billion years younger than previously thought. Using advanced geochronology techniques, scientists have dated these deposits to between 1.1 and 1.4 billion years, reshaping our understanding of Earth's geological history and aiding future exploration efforts.The Science ReportA study suggests that a daily hour-long walk for those over 40 could extend life expectancy by five years. Meanwhile, global plastic waste is projected to double by mid-century, but a combination of policies could reduce it by 90%. Additionally, switching to a vegan diet could lower food costs by 19%, unlike the Mediterranean diet. The Bent Spoon Award was given to the Cancer Council of Western Australia for endorsing pseudoscientific practices like Richie.www.spacetimewithstuartgary.comwww.bitesz.com🌏 Get Our Exclusive NordVPN deal here ➼ www.bitesz.com/nordvpn.

SpaceTime Series 27 Episode 141*Supermassive Black Hole Consumes Matter at Record SpeedAstronomers have discovered a supermassive black hole in the early universe consuming matter at a rate more than 40 times its theoretical limit. This black hole, catalogued as LID568, was observed by the Webb Space Telescope and is providing new insights into the rapid growth mechanisms of black holes shortly after the Big Bang. The findings challenge existing theories on how these cosmic giants formed so quickly and open new avenues for future research.*Uranus' Magnetic Mysteries UnveiledNew analysis of 38-year-old data from NASA's Voyager 2 spacecraft reveals that a space weather event dramatically compressed Uranus' magnetosphere just before the flyby in 1986. This event provides clues to the planet's unusual magnetic field and suggests that Uranus' moons might be more geologically active than previously thought. The findings are crucial for understanding this enigmatic ice giant and its unique characteristics.*New Satellite to Track Earth's Surface MovementsScientists are preparing to launch a new satellite, the NASA-ISRO Synthetic Aperture Radar (NISAR), designed to measure ground movement on Earth's surface. Scheduled for launch next year, NISAR will provide detailed data on earthquakes, volcanoes, and landslides, enhancing our ability to prepare for natural disasters. This mission will offer unprecedented insights into the dynamics of our planet's surface.The Science ReportThe World Meteorological Organization predicts 2024 to be the hottest year on record, driven by rising greenhouse gas levels. Meanwhile, ultra-processed foods are dominating global diets, linked to numerous chronic diseases. A study of dog breeds reveals that toy dogs have larger brains relative to their body size compared to working dogs. Lastly, a retrospective look at NASA's 1996 tether experiment debunks UFO theories, emphasizing the importance of scientific explanations.www.spacetimewithstuartgary.comwww.bitesz.com🌏 Get Our Exclusive NordVPN deal here ➼ www.bitesz.com/nordvpn.

SpaceTime Series 27 Episode 140*Revisiting the Milky Way's Black Hole ImageA 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 CrustData 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 HoleNASA 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 ReportAntarctic 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.www.spacetimewithstuartgary.comwww.bitesz.com🌏 Get Our Exclusive NordVPN deal here ➼ www.bitesz.com/nordvpn.

SpaceTime Series 27 Episode 139*Gilmore Space Cleared for Orbital LaunchThe 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 UniverseAstronomers 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 OceanChina'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 RobertArchaeologists 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.www.spacetimewithstuartgary.comwww.bitesz.com🌏 Get Our Exclusive NordVPN deal here ➼ www.bitesz.com/nordvpn.
