Utilizing the advanced capabilities of the Australian Square Kilometer Array Pathfinder (ASCAP), researchers reveal the unique characteristics of these galaxies, including their powerful jets and lobes traveling at superluminal speeds. We delve into the implications of these findings for our understanding of galaxy formation and evolution.Changes on TitanNext, we discuss the intriguing changes occurring on Saturn's moon Titan, which is experiencing rapid orbital changes on geological timescales. Scientists explore the factors influencing Titan's tidal dissipation rate and what it reveals about the moon's internal structure and history. This study provides insights into the dynamic processes at play in our solar system's moons.Failed Soviet Spacecraft ReturnsWe also cover the dramatic re-entry of the Kosmos 482, a failed Soviet spacecraft that spent 53 years in orbit before crashing back to Earth. Launched in 1972 on a mission to Venus, the spacecraft's uncontrolled descent raises concerns about space debris and its potential impact on Earth.AI and Humanity's FutureFinally, we tackle the controversial topic of artificial intelligence and its potential risks to humanity. With AI evolving at an unprecedented pace, we examine the findings of a new study that assesses the likelihood of AI leading to human extinction. As science fiction warns of a future dominated by AI, we explore the reality of these threats and what they mean for our future.www.spacetimewithstuartgary.com✍️ Episode ReferencesScience Advanceshttps://www.science.org/journal/sciadvJournal of the American Medical Associationhttps://jamanetwork.com/journals/jamaBecome a supporter of this podcast: https://www.spreaker.com/podcast/spacetime-space-astronomy--2458531/support.00:00 This is space time series 28, episode 57 for broadcast on 12 May 202500:54 Astronomers have discovered 15 giant radio galaxies each hosting a supermassive black hole09:35 You're still learning about these galaxies11:57 Now you, uh, mentioned starburst galaxies earlier.

Researchers are now investigating gamma-ray burst jets and the surrounding cocoon formed by collapsed stars. This new framework suggests that high-energy photons can dissolve stellar material into neutrons, leading to the creation of heavy elements through a rapid neutron capture process. We discuss the implications of these findings and how they challenge long-held beliefs about nucleosynthesis in the universe.Shattering Beliefs About Asteroid VestaNext, we turn our attention to the asteroid Vesta, where a recent study published in Nature Astronomy reveals that its interior structure is far more uniform than previously thought. This discovery has led scientists to reconsider Vesta's identity, proposing that it may simply be a large asteroid rather than a protoplanet. We examine the research that challenges decades of assumptions about Vesta's formation and its role in understanding the early solar system.Did It Rain or Snow on Ancient Mars?Finally, we investigate the ancient climate of Mars, with a new study suggesting that geological formations on the planet were shaped by heavy precipitation, indicating a warmer and wetter past. This research utilizes computer simulations to analyze how rain and snow may have contributed to the development of Martian valleys and channels. We discuss the significance of these findings and their implications for our understanding of Mars's climatic history.www.spacetimewithstuartgary.com✍️ Episode ReferencesAstrophysical Journalhttps://iopscience.iop.org/journal/0004-637XNature Astronomyhttps://www.nature.com/natureastronomy/Journal of Geophysical Research Planetshttps://agupubs.onlinelibrary.wiley.com/journal/21699356Become a supporter of this podcast: https://www.spreaker.com/podcast/spacetime-space-astronomy--2458531/support.00:00 New study provides clues explaining how exploding stars produce uranium and other heavy elements06:21 New study suggests giant asteroid Vesta is really just a big asteroid15:19 New study suggests heavy precipitation likely fed valleys on ancient Mars19:49 A new study warns that microplastic pollution could compromise ocean carbon22:17 More than 31,000 passwords belonging to Australian banks have been stolen24:47 Space Time is available every Monday, Wednesday and Friday through bitesz.com
