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.

    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.
