Dark Matter's Role in the Milky Way A new study suggests that dark matter could be the driving force behind the gravitational dynamics of our Milky Way galaxy. Researchers propose that a clump of fermionic dark matter might exert similar gravitational influence as the supermassive black hole at the galaxy's center, Sagittarius A. This theory challenges conventional understanding and is supported by data from the European Space Agency's Gaia mission, which mapped the galaxy's outer halo and rotational curve, indicating a potential new model for understanding galactic structures. Lunar Far Side's Cooler Interior Recent findings published in Nature Geoscience indicate that the lunar far side may be significantly cooler than the near side. Analyzing samples collected by China's Chang'e 6 mission, scientists discovered that the far side's regolith formed from lava at temperatures approximately 100 degrees Celsius lower than those from the near side. This study provides insight into the Moon's geological history and the uneven distribution of heat-producing elements, which may have resulted from ancient impacts or tidal forces from Earth. Jupiter's Slimmer Profile New measurements from NASA's Juno mission reveal that Jupiter is actually slimmer than previously thought, being about 8 kilometers narrower at the equator and 24 kilometers flatter at the poles. These findings refine our understanding of the gas giant's shape and have implications for models of planetary formation and evolution. The data also sheds light on Jupiter's atmospheric dynamics, including its powerful winds and cyclones, enhancing our knowledge of gas giants both within our solar system and beyond. www.spacetimewithstuartgary.com ✍️ Episode References Monthly Notices of the Royal Astronomical Society, Nature Geoscience, Nature Astronomy Become a supporter of this podcast: https://www.spreaker.com/podcast/spacetime-with-stuart-gary--2458531/support.

    Europa's Ice Shell and Planet Nine: Unveiling the Thickness of Frozen Worlds and Cosmic Oddities

    SpaceTime with Stuart Gary Gary - Series 29 Episode 16 In this episode of SpaceTime, we dive into groundbreaking revelations about Europa's ice shell, explore new evidence for the existence of a potential Planet Nine, and discuss a significant advancement in quantum physics that challenges the Heisenberg Uncertainty Principle. Europa's Ice Shell Thickness Revealed Data from NASA's Juno mission has provided the first insights into the thickness of Europa's icy crust, estimating it to be around 29 kilometers. This measurement comes from Juno's 2022 flyby, where the spacecraft utilized its microwave radiometer to analyze the moon's surface temperature and characteristics. The findings suggest that beneath this thick ice lies a global ocean of liquid water, potentially harboring the ingredients necessary for life. Understanding the ice shell's structure is crucial for future missions, including NASA's Europa Clipper, set to arrive in 2030. The Case for Planet Nine A new study published in Nature Astronomy presents fresh simulations suggesting that wide-orbit planets, like the hypothesized Planet Nine, could be a natural outcome of chaotic early planetary systems. Researchers found that during turbulent phases of stellar formation, planets can be flung into distant orbits rather than being ejected entirely. This work offers a 40% chance that a Planet Nine-like object exists, providing a promising avenue for future exploration as telescopes become more capable of surveying the distant solar system. Advancements in Quantum Physics In a remarkable breakthrough, physicists have demonstrated a method to sidestep the Heisenberg Uncertainty Principle, allowing for simultaneous precise measurements of a particle's position and momentum. This innovative approach, detailed in Science Advances, could pave the way for ultra-precise sensor technologies across various fields, including navigation and astronomy. The study redefines the boundaries of quantum measurement, offering new possibilities for scientific exploration. www.spacetimewithstuartgary.com ✍️ Episode References Nature Astronomy Science Advances Become a supporter of this podcast: https://www.spreaker.com/podcast/spacetime-your-guide-to-space-astronomy--2458531/support.

    Mercury's Hidden Activity and Titan's Dragonfly: Exploring Volatile Streaks and Robotic Rotocopters

    SpaceTime with Stuart Gary Gary - Series 29 Episode 15 In this episode of SpaceTime, we uncover intriguing discoveries about Mercury's geological activity, NASA's innovative Dragonfly mission to Titan, and the environmental impacts of rocket fuel pollution. Mercury's Surprising Streaks A new study reveals bright streaks, or lineae, on Mercury's surface, suggesting the planet is not as geologically inactive as previously thought. Researchers from the University of Bern utilized machine learning to analyze over 100,000 images from NASA's MESSENGER spacecraft, discovering that these streaks are likely caused by the outgassing of volatile materials from beneath Mercury's crust. This finding indicates ongoing geological processes and will be further explored by the BepiColombo mission, set to reach Mercury later this year. NASA's Dragonfly Mission to Titan NASA is developing the Dragonfly, a car-sized rotocopter designed to explore Saturn's moon Titan, which features methane and ethane lakes. Scheduled for launch in 2028, Dragonfly will utilize Titan's dense atmosphere to fly to various locations, examining environments that may harbor organic materials essential for life. The mission builds on the success of the Ingenuity rotocopter on Mars, with extensive testing underway to ensure optimal performance in Titan's unique conditions. Rocket Fuel Pollution and the Ozone Layer A recent study highlights the damaging effects of burning rocket fuels, such as kerosene, on Earth's ozone layer. The report indicates that the rapid growth of the rocket launch industry is exacerbating this issue, particularly affecting regions like Antarctica and parts of Australia. Researchers are calling for restrictions on the use of these fuels to mitigate environmental harm. www.spacetimewithstuartgary.com ✍️ Episode References Nature Communications, Earth and Environment Climate and Atmospheric Science Become a supporter of this podcast: https://www.spreaker.com/podcast/spacetime-your-guide-to-space-astronomy--2458531/support.

    Earth's Water Origins and Io's Volcanic Secrets: Unveiling Tectonic Climate Drivers and Lunar Archives

    In this episode of SpaceTime, we explore new insights into the origins of Earth's water, groundbreaking discoveries beneath the surface of Jupiter's volcanic moon Io, and how tectonic plate movements may have influenced Earth's climate throughout history. New Clues on Earth's Water Origins A recent study published in the Proceedings of the National Academy of Sciences reveals that asteroid and comet impacts could only account for a small fraction of Earth's water supply. By analyzing oxygen isotopes in lunar regolith collected during the Apollo missions, researchers found that the early Earth likely retained little to no water during its formative years. This challenges long-held beliefs and suggests that the majority of Earth's water must have originated from other sources, rather than being delivered by celestial bodies. Unprecedented Volcanic Activity on Io NASA's Juno spacecraft has captured remarkable data on Io, the most volcanically active body in our solar system. Observations from a December flyby revealed the most energetic eruption ever detected on Io, affecting a vast area of 65,000 square kilometers. The findings indicate that interconnected magma reservoirs beneath Io's surface are responsible for this extraordinary volcanic activity, providing new insights into the moon's geological dynamics and evolution. Tectonic Plates and Earth's Climate A new study suggests that carbon released from shifting tectonic plates may have played a significant role in Earth's climatic transitions, rather than volcanic activity as previously thought. Researchers reconstructed carbon movements over the last 540 million years, providing evidence that carbon emissions from mid-ocean ridges were the primary drivers of climate shifts between ice ages and warmer periods. This research reshapes our understanding of past climate dynamics and offers valuable insights for future climate models. www.spacetimewithstuartgary.com ✍️ Episode References Proceedings of the National Academy of Sciences Journal of Geophysical Research Planets Communications Earth and Environment Become a supporter of this podcast: https://www.spreaker.com/podcast/spacetime-your-guide-to-space-astronomy--2458531/support.

SpaceTime with Stuart Gary Gary - Series 29 Episode 13 In this episode of SpaceTime, we uncover the hidden violent past of the Milky Way's supermassive black hole, delve into the origins of water on Jupiter's Galilean moons, and explore how meteor impacts are triggering dust avalanches on Mars. The Violent History of Sagittarius A For years, Sagittarius A, the supermassive black hole at the center of our galaxy, has been perceived as a quiet entity. However, new research published in the Astrophysical Journal Letters indicates that it may have experienced dramatic flares in the past. Observations from the CRISM Space Telescope reveal X-ray emissions from a gas cloud near Sagittarius A, suggesting a history of explosive activity that alters our understanding of supermassive black hole evolution and the history of our galaxy. Water Origins of Jupiter's Galilean Moons A groundbreaking study has determined that the contrasting water content of Jupiter's four large Galilean moons was established during their formation rather than evolving later. This research sheds light on the stark differences between Io, which is dry and volcanically active, and Europa, believed to have a subsurface ocean. The findings suggest that the primordial environment around Jupiter played a crucial role in shaping these moons' compositions. Meteor Impacts Trigger Dust Avalanches on Mars New evidence indicates that meteor impacts on Mars are causing dust avalanches, creating dark streaks on the planet's surface. An analysis of images from the European Space Agency's ExoMars Trace Gas Orbiter reveals that these avalanches occur primarily due to dry processes, driven by seasonal dust and wind activity, rather than water-related phenomena. This discovery enhances our understanding of Martian surface dynamics and the impact of meteor activity. www.spacetimewithstuartgary.com ✍️ Episode References Astrophysical Journal Letters Nature Communications Become a supporter of this podcast: https://www.spreaker.com/podcast/spacetime-your-guide-to-space-astronomy--2458531/support.
