In this episode of SpaceTime, we uncover exciting new research challenging our understanding of dark matter, reveal hidden treasures beneath the Earth's surface, and explore the potential for life on Titan, Saturn's enigmatic moon. Modified Newtonian Dynamics: A Dark Matter Alternative Recent studies suggest that modified Newtonian dynamics (MOND) may serve as a viable alternative to the elusive dark matter hypothesis. This theory, proposed by physicist Mordecai Milgrom, modifies Newton's laws to explain the gravitational behavior observed in galaxies without relying on dark matter. We delve into the latest findings that support MOND, including a novel method for measuring gravity in wide binary star systems, which indicates that gravity may actually be stronger than Newton's predictions under certain conditions. Earth's Hidden Gold Reserves A groundbreaking study reveals that Earth's core may contain vast reserves of gold and other precious metals, far beyond what is accessible on the surface. Researchers discovered traces of ruthenium in volcanic rocks from Hawaii, suggesting that these metals originated from the core and are leaking into the mantle. This research opens new avenues for understanding Earth's internal dynamics and the movement of materials from the core to the surface. Searching for Life's Chemistry on Titan NASA's upcoming Dragonfly mission aims to investigate the intriguing chemistry of life on Titan, Saturn's largest moon. With its organic-rich environment and unique geological features, Titan presents an opportunity to study prebiotic chemistry in a way that Earth cannot.

SpaceX's Fiery Ninth Starship Test Flight The latest test flight of SpaceX's Starship ended dramatically as both the orbiter and the booster were destroyed during reentry. Despite the fiery conclusion, SpaceX officials noted that the test was designed to push the limits of the spacecraft. The flight featured numerous milestones, including a successful hot staging and the first reflight of a booster. However, issues arose during the landing burn, resulting in a spectacular explosion. We discuss the implications of this test and what it means for future missions, including NASA's Artemis 3. Lunar Rocks and Their Magnetic Mystery A new study proposes that a significant asteroid impact may explain the presence of highly magnetic rocks on the Moon. Researchers suggest that a brief amplification of the Moon's weak magnetic field, caused by a large plasma-generated impact event, could account for the magnetism observed in some lunar samples. This hypothesis sheds light on the Moon's geological history and its magnetic properties, particularly in regions near the lunar south pole, where future missions are planned. Revealing the Sun's Corona Astronomers have captured unprecedented details of the Sun's corona using a new adaptive optics system.

In this episode of SpaceTime, we tackle some of the universe's most pressing mysteries, including new insights into the Hubble constant, the surprising geology of Venus, and the building blocks of stellar formation. Resolving the Hubble Constant Debate New data from the James Webb Space Telescope may have finally reconciled the long-standing discrepancy in the measurement of the Hubble constant, the rate at which the universe expands. For years, scientists have grappled with differing values derived from cosmic microwave background radiation and supernova observations. Lead author Wendy Friedman discusses how recent findings suggest that the standard model of cosmology holds up, with the Hubble constant now estimated at 70.4 kilometres per second per megaparsec, aligning more closely with earlier measurements. This breakthrough could reshape our understanding of the universe’s expansion and evolution. Venus's Thin Crust New research indicates that Venus's crust is unexpectedly thin, challenging previous assumptions about the planet's geology. A study published in Nature Communications reveals that Venus lacks the tectonic activity seen on Earth, resulting in a crust that is about 40 to 65 kilometres thick. This research proposes a model of crust metamorphism that could explain how volcanic activity persists on Venus, despite the absence of plate tectonics. Upcoming missions, including NASA's Davinci and Veritas, aim to gather more data that could confirm these findings and enhance our understanding of Venus's geological processes. Building Blocks of Stellar Formation A recent study highlights that the formation of stars is influenced not only by the amount of gas in a galaxy but also by its distribution. Observations from the WALLABY survey, conducted using the Australian Square Kilometre Array Pathfinder Telescope, reveal that star formation is concentrated in areas with higher gas density. Lead author Seona Lee explains how this research sheds light on the intricate processes that govern star formation, suggesting that gas location is critical for the birth of new stars across various galaxy types. www.spacetimewithstuartgary.com ✍️ Episode References Astrophysical Journal https://iopscience.iop.org/journal/0004-637X Nature Communications https://www.nature.com/naturecommunications/ Become a supporter of this podcast: https://www.spreaker.com/podcast/spacetime-space-astronomy--2458531/support . 00:00 This is Space Time Series 28, Episode 66 for broadcast on 2 June 2025 01:00 Resolving the Hubble constant debate 12:15 Venus's surprisingly thin crust 22:30 Building blocks of stellar formation 30:00 Science report: New links between autism and Parkinson's disease…
