• NISAR Launch: Unveiling Earth's Secrets Through Radar

  In this episode of SpaceTime, we journey through the latest advancements in space exploration and cosmology, featuring a groundbreaking radar mission, a new hypothesis on the universe's origins, and updates on the International Space Station.NISAR: A New Era in Earth ObservationThe Indian Space Research Organisation (ISRO) has successfully launched the NISAR satellite, a joint mission with NASA that promises to revolutionise our understanding of Earth's dynamic systems. This advanced synthetic aperture radar satellite will monitor changes in forests, wetlands, and ice-covered surfaces with unprecedented detail, providing crucial data for disaster response, infrastructure management, and climate change studies. With its ability to see through clouds and operate day and night, NISAR will deliver vital insights into the planet's movements and environmental changes every 12 days, enhancing our preparedness for natural hazards.A New Hypothesis on the Universe's OriginsIn a significant shift in cosmological theory, scientists have proposed a new model that explains the universe's early moments without relying on speculative elements. This revolutionary hypothesis, reported in the journal Physical Review Research, suggests that natural quantum fluctuations in a state known as de Sitter space could account for the density differences that led to the formation of galaxies and stars. By eliminating arbitrary parameters, this model offers a clearer understanding of the cosmos and poses fundamental questions about our existence and origins.Russia's Commitment to the International Space StationIn a surprising announcement, Russia has confirmed its intention to remain a partner in the International Space Station (ISS) project until at least 2028, despite previous threats to withdraw. This decision comes amid ongoing geopolitical tensions and technical challenges within the Russian segment of the ISS. As the global space community continues to evolve, Russia's commitment ensures continued collaboration in low Earth orbit, even as plans for an independent Russian space station progress.www.spacetimewithstuartgary.com✍️ Episode ReferencesPhysical Review Researchhttps://journals.aps.org/prresearch/NASA NISAR Missionhttps://www.nasa.gov/nisarBecome a supporter of this podcast: https://www.spreaker.com/podcast/spacetime-space-astronomy--2458531/support.

• Planetary Demise - Tracking the Death Spiral of TOI 2109b

  In this episode of SpaceTime, we delve into the cosmic drama unfolding in our universe, featuring a doomed exoplanet, new revelations about Mars, and the latest crew aboard the International Space Station.The Death Spiral of TOI 2109bAstronomers are closely monitoring the death spiral of TOI 2109b, an exoplanet located over 870 light-years away. This gas giant, nearly five times the mass of Jupiter, completes an orbit around its host star in just 16 hours, making it the closest hot Jupiter discovered to date. Researchers from Macquarie University have found that the planet's orbit is decaying, leading to three potential end scenarios: being torn apart by tidal forces, plunging into its host star, or losing its gaseous envelope to intense radiation. These findings provide valuable insights into planetary evolution and the fate of gas giants in close orbits.New Insights into Mars's Ancient SurfaceA recent study has identified a new type of iron sulfate on Mars, suggesting significant geothermal and chemical activity on the planet's surface. Researchers have characterized this uncommon mineral, which may represent a new type due to its unique crystalline structure. The discovery sheds light on how heat, water, and chemical reactions have shaped Mars, and indicates that the planet may have been more geologically active than previously thought. This research enhances our understanding of Mars's potential to have supported life in its past.New Crew Arrives at the International Space StationNASA has successfully delivered a new crew to the International Space Station aboard a SpaceX Dragon capsule. The crew, consisting of two Americans, a Russian, and a Japanese astronaut, will replace colleagues who have been aboard since March. As NASA considers extending crew stays from six to eight months to reduce costs, the new team is set to contribute to ongoing research and operations in low Earth orbit.www.spacetimewithstuartgary.com✍️ Episode ReferencesAstrophysical Journalhttps://iopscience.iop.org/journal/1538-4357Nature Journalhttps://www.nature.com/nature/NASA's International Space Stationhttps://www.nasa.gov/mission_pages/station/main/index.htmlBecome a supporter of this podcast: https://www.spreaker.com/podcast/spacetime-space-astronomy--2458531/support.00:00 This is space Time Series 28, Episode 97 for broadcast on 13 August 202500:42 Astronomers are tracking the death spiral of a doomed planet more than 870 light years away12:06 ToI 2109 is one of the most interesting systems that we've got17:06 Scientists have identified a new type of iron sulfate on the Red Planet23:47 NASA has delivered four new crew members to the International Space Station aboard SpaceX Dragon25:10 New study claims consuming three fries a week increases risk of developing type 2 diabetes26:13 Google about to offer AI study tools to college students for free29:53 You've got to check for updates on all your Apple devices

• Cosmic Monsters and Martian Rivers

  In this episode of SpaceTime, we explore groundbreaking discoveries and ambitious plans in the realm of space exploration.The Most Distant Black Hole: Casper's Lidz 9Astronomers have identified the most distant black hole ever observed, known as Casper's Lidz 9, dating back 13.3 billion years to a time when the universe was only half a billion years old. This supermassive black hole, weighing in at approximately 300 million solar masses, raises intriguing questions about its rapid growth in the early universe. The findings, published in the Astrophysical Journal, provide a unique opportunity to study the structure and evolution of galaxies during this enigmatic period, with implications for our understanding of black hole formation.New Insights into Ancient Martian WaterRecent research suggests that Mars was even wetter than previously believed. A study presented at the Royal Astronomical Society's national meeting examined over 1500 kilometres of ancient riverbeds in the Nochesterra region, indicating that flowing water was widespread during the Noche and Hesperian transition around 3.7 billion years ago. These findings challenge existing theories about Mars's dry history and suggest a more complex and active planet, potentially providing a more hospitable environment for ancient life.Nuclear Reactors for Moon and Mars BasesThe United States has unveiled plans to develop nuclear reactors to power future bases on the Moon and Mars, with the first plant expected to launch by the end of the decade. This initiative aims to support sustained human presence on these celestial bodies, addressing energy needs that solar power cannot fulfil. The reactors will provide essential electricity for life support, scientific equipment, and resource utilisation, marking a significant step in the ongoing space race.www.spacetimewithstuartgary.com✍️ Episode ReferencesAstrophysical Journalhttps://iopscience.iop.org/journal/1538-4357NASA's Artemis Programhttps://www.nasa.gov/specials/artemis/Become a supporter of this podcast: https://www.spreaker.com/podcast/spacetime-space-astronomy--2458531/support.
