Galactic Mysteries: Unveiling Supermassive Black Holes and the Secrets of Comet 3I Atlas
Episode 4
Friday, 9 January, 2026
SpaceTime with Stuart Gary Gary - Series 29 Episode 4In this episode of SpaceTime, we explore the latest revelations about supermassive black holes, the enigmatic interstellar comet 3I Atlas, and NASA's innovative tests on lunar surface interactions.Do All Galaxies Host Supermassive Black Holes?A groundbreaking study utilizing NASA's Chandra X-ray Observatory challenges the long-held belief that all galaxies harbor supermassive black holes at their centers. Analyzing data from over 1,600 galaxies, researchers discovered that only about 30% of dwarf galaxies contain these cosmic giants. The findings, published in the Astrophysical Journal, provide crucial insights into the formation of supermassive black holes and suggest that smaller galaxies may have significantly fewer black holes than their massive counterparts.No Evidence of Alien Intelligence from Comet 3I AtlasDespite sensational claims, a thorough investigation into the interstellar comet 3I Atlas has yielded no signs of extraterrestrial technology. Observations from the Green Bank Radio Telescope during the comet's closest approach revealed only radio frequency interference, dismissing earlier speculations of alien signals. The analysis reinforces the understanding that the comet's behavior aligns with natural phenomena, rather than advanced civilizations.NASA's Rocket Plume Studies on Lunar RegolithNASA is conducting new experiments to understand how rocket plumes interact with the lunar surface, crucial for future lunar landings. Using a sophisticated camera system, scientists are simulating rocket engine behavior in a vacuum chamber to analyze the impact of exhaust on lunar dust and rocks. The data collected will inform the design of landing systems for the Artemis missions and future Mars explorations, ensuring crew safety and mission success.www.spacetimewithstuartgary.com✍️ Episode ReferencesAstrophysical JournalNASA ReportsJournal of Molecular and Cellular BiochemistryBecome a supporter of this podcast: https://www.spreaker.com/podcast/spacetime-your-guide-to-space-astronomy--2458531/support.(00:00:00) This is Space Time Series 29, Episode 4 for broadcast on 9 January 2026(00:00:47) Study reveals fewer supermassive black holes in smaller galaxies(00:12:30) No signs of alien technology from comet 3I Atlas(00:20:10) NASA's lunar regolith plume interaction tests(00:25:00) Science report: Microplastics and neurodegenerative diseases, dog ownership and community ties
