This theory, outlined in the journal Physical Review Letters, proposes that these particles formed during the early universe's chaotic conditions, akin to steam turning into water. We discuss how this model could be tested using existing cosmic microwave background radiation data, potentially revolutionizing our understanding of dark matter's properties and formation.Visible Light Auroras on MarsIn a historic achievement, NASA's Perseverance rover has captured the first visible light auroras on Mars, confirming long-held theories about Martian atmospheric phenomena. This event, triggered by a massive solar flare, opens up new avenues for auroral research and suggests that future astronauts could witness these stunning displays on the Martian surface. We explore the implications of this discovery and how it enhances our understanding of solar interactions with planetary atmospheres.Quasiperiodic Eruptions: A New Type of X-ray ExplosionAstronomers have identified a new type of X-ray outburst known as quasiperiodic eruptions, occurring near supermassive black holes. Observed in a galaxy 300 million light-years away, these eruptions exhibit a unique pattern, with events occurring every 4.5 days. We discuss the mechanisms behind these eruptions and their significance in understanding the dynamics of black holes and their surrounding environments.www.spacetimewithstuartgary.com✍️ Episode ReferencesPhysical Review Lettershttps://journals.aps.org/prl/Science Advanceshttps://www.science.org/journal/sciadvAstrophysical Journalhttps://iopscience.iop.org/journal/0004-637XBecome a supporter of this podcast: https://www.spreaker.com/podcast/spacetime-space-astronomy--2458531/support.00:00 This is Space Time Series 28, Episode 62 for broadcast on 23 May 202501:00 New theory explaining the birth of dark matter12:15 First visible light auroras detected on Mars20:30 Discovery of quasiperiodic eruptions near supermassive black holes30:00 Science report: AI chatbots exaggerate research summaries

• Solar Flare Frenzy: Earth's Brush with the Biggest Geomagnetic Storm in 20 Years

  This episode of SpaceTime explores the recent surge in solar activity, including the largest solar flare of the year and the most intense geomagnetic storm in two decades.Massive Solar Flare and Its ImplicationsWe delve into the details of a powerful X 2.7 class solar flare that erupted from a newly active sunspot region, AR14087. Although the flare was not initially directed towards Earth, its rotation has now positioned it directly in our path. We discuss the mechanics of solar flares, their classification, and the potential impacts of such events on our planet, including disruptions to communication systems, satellite operations, and even power grids.The Gannon Storm: A Historic Geomagnetic EventThe episode highlights the Gannon Storm, a severe geomagnetic storm that struck Earth on May 10, 2024. Coinciding with a space weather exercise, this event caused significant disruptions, including high voltage power line failures and rerouted flights due to radiation exposure. We analyze its effects on the atmosphere, satellites, and even the ionosphere, revealing insights into how such storms can impact modern technology.Ancient Solar Storms and Their Modern ImplicationsIn a fascinating segment, we discuss a groundbreaking study that identifies the strongest solar storm ever recorded, dating back to 12350 BCE. This ancient event, significantly more intense than any modern storm, provides invaluable data for understanding solar activity and its potential risks to contemporary infrastructure.Science Robert: Long Work Hours and Brain ChangesWe also touch on a new study revealing how long working hours could alter brain structures, potentially affecting memory and emotional regulation.Join us as we unpack these cosmic phenomena and their implications for life on Earth and beyond.www.spacetimewithstuartgary.com✍️ Episode ReferencesJournal of Occupational Environmental Medicinehttps://journals.lww.com/joem/Pages/default.aspxBecome a supporter of this podcast: https://www.spreaker.com/podcast/spacetime-space-astronomy--2458531/support.00:00 Solar flares are powerful blasts of energy erupting from sunspots10:30 May 2024 was the biggest geomagnetic storm in over 20 years14:29 New study reveals strongest solar event ever recorded, rewriting science on space weather18:23 A new study claims people who work long hours could have altered brain structures

• Eris Rocket Launch Delays, Venus's Tectonic Secrets, and Scotland's Billion-Year-Old Impact

  This episode of SpaceTime covers a range of exciting topics, including the delayed launch of Gilmour Space's Eris rocket, groundbreaking discoveries on Venus, and a billion-year-old asteroid impact in Scotland that raises new questions about the evolution of life on Earth.Eris Rocket Launch DelayedGilmour Space has postponed the maiden launch of its Eris orbital rocket due to technical issues encountered during pre-flight checks. The rocket, designed to carry small satellite payloads, will now face a delay of at least three weeks as the company investigates the unexpected deployment of the launch vehicle's nosecone fairings. We discuss the implications of this delay and what it means for future commercial launches.Tectonic Activity on VenusIn a fascinating discovery, scientists have identified possible tectonic activity on Venus, based on data from NASA's Magellan mission. Researchers found evidence of unique geological features known as coronae, which may indicate ongoing deformation of the planet's surface due to molten material from below. This research not only enhances our understanding of Venus but also offers insights into Earth's geological history.Ancient Asteroid Impact in ScotlandA recent study has revealed that a massive asteroid impact in Scotland occurred 990 million years ago, much later than previously thought. This discovery, based on dating tiny zircon crystals, suggests a connection between this impact event and the emergence of early freshwater eukaryotes on land. We delve into the implications of this revised timeline for our understanding of life on Earth and the environmental changes triggered by such impacts.www.spacetimewithstuartgary.com✍️ Episode ReferencesScience Advanceshttps://www.science.org/journal/sciadvJournal of Geologyhttps://www.geosociety.org/publications/gsa/geo.aspBecome a supporter of this podcast: https://www.spreaker.com/podcast/spacetime-space-astronomy--2458531/support.00:00 This is Space Time Series 28, Episode 60 for broadcast on 19 May 202500:54 Gilmour Space's Eris rocket launch delayed10:15 Possible tectonic activity discovered on Venus18:45 Billion-year-old asteroid impact in Scotland raises questions about early life on Earth25:00 Science report: Unexplained communications equipment found in Chinese-made solar panel inverters
