SpaceTime with Stuart Gary Gary - Series 29 Episode 4 In 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 Atlas Despite 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 Regolith NASA 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 (https://www.spacetimewithstuartgary.com/) ✍️ Episode References Astrophysical Journal NASA Reports Journal of Molecular and Cellular Biochemistry Become a supporter of this podcast: https://www.spreaker.com/podcast/spacetime-your-guide-to-space-astronomy--2458531/support (https://www.spreaker.com/podcast/spacetime-your-guide-to-space-astronomy--2458531/support?utm_source=rss&utm_medium=rss&utm_campaign=rss) .

SpaceTime with Stuart Gary Gary - Series 29 Episode 3 In this episode of SpaceTime , we delve into the latest discoveries in astrophysics and the challenges faced by space agencies worldwide. Ancient Supernova Offers Clues to Dark Energy Astronomers have made significant strides in understanding dark energy, the enigmatic force driving the universe's accelerated expansion. A newly observed supernova, located 10 billion light years away, has been gravitationally lensed by a foreground galaxy, allowing scientists to analyze multiple images of the same explosion. This phenomenon could help determine the Hubble constant, shedding light on the universe's expansion rate and its ultimate fate, which ranges from a Big Crunch to a Big Rip. Sterile Neutrino Hypothesis Nearly Ruled Out After over a decade of research, scientists have come close to ruling out the existence of the sterile neutrino, a proposed particle that could explain anomalous neutrino behavior. Data from the Micro BooNE experiment at Fermilab has shown no signs of sterile neutrinos, providing a pivotal moment in particle physics that narrows the search for new theories beyond the standard model. China's Reusable Rocket Setback China's efforts to develop a reusable rocket faced a significant blow as its Long March 12A failed on its maiden flight. Although the rocket's first and second stages performed as expected, the first stage failed to return successfully, highlighting the challenges in achieving reusability akin to SpaceX's Falcon 9. This setback underscores the competitive nature of the global space industry as China strives to enhance its capabilities. www.spacetimewithstuartgary.com (https://www.spacetimewithstuartgary.com/) ✍️ Episode References Astrophysical Letters Nature Fermilab Reports Become a supporter of this podcast: https://www.spreaker.com/podcast/spacetime-your-guide-to-space-astronomy--2458531/support (https://www.spreaker.com/podcast/spacetime-your-guide-to-space-astronomy--2458531/support?utm_source=rss&utm_medium=rss&utm_campaign=rss) .
