Observations from the Webb Space Telescope have identified young rogue planets with masses between 5 to 10 times that of Jupiter. These dim objects, which emit primarily in the infrared spectrum, are believed to hold secrets about the formation of planetary systems. The findings indicate that disks of warm dust surrounding these planets could provide the necessary materials for planet formation, suggesting that such systems could exist even in the absence of stars.Europe's Space Rider ProgressesThe European Space Agency's reusable Space Rider spacecraft has successfully completed a crucial test of its nose cone, marking another milestone in its development. This innovative spacecraft will allow ESA to conduct orbital missions and return scientific payloads to Earth. Designed to operate as an unmanned laboratory in low Earth orbit, Space Rider will support a variety of experiments and technology demonstrations, paving the way for Europe to enhance its capabilities in space exploration.Harvesting Solar Power from SpaceCould space-based solar panels be the solution to our energy needs? Scientists are investigating two promising projects aimed at capturing solar energy in orbit. The Innovative Heliostat Swarm aims to create a network of mirrors that direct sunlight to a central receiver, converting it into electricity for transmission back to Earth. Meanwhile, the Mature Planar Array is closer to deployment but will only capture solar energy about 60% of the time. Despite current challenges in cost-effectiveness, these projects could lead to breakthroughs in sustainable energy.www.spacetimewithstuartgary.com✍️ Episode ReferencesAstrophysical Journalhttps://iopscience.iop.org/journal/2041-8205European Space Agencyhttps://www.esa.int/Journal of Solar Energyhttps://www.journals.elsevier.com/solar-energyBecome a supporter of this podcast: https://www.spreaker.com/podcast/spacetime-space-astronomy--2458531/support.

• Cosmic Horror: The Discovery of a Wandering Black Hole and a Meteorite's Journey

  This episode of SpaceTime is brought to you by Insta360's newest camera, the GoUltra. To get more details on this go anywhere camera, visit store.insta360.com and for our special offer use the code SPACETIME at checkout.In this episode of SpaceTime, we uncover the mysteries lurking in the cosmos, from a rogue supermassive black hole to a meteorite crash in Georgia, and the origins of asteroids Bennu and Ryugu.An Invisible Monster in the CosmosAstronomers have made a chilling discovery of a supermassive black hole, 600 million light years away, that has been lurking in the darkness of space. Using NASA's Hubble and Chandra space telescopes, along with a Very Large Array radio telescope, researchers identified this rogue black hole that consumes stars and planets that venture too close. The black hole was revealed through a tidal disruption event, where a star was torn apart and swallowed, offering a glimpse into the physics of these cosmic behemoths.Meteorite Slams into Georgia HomeIn an extraordinary event, a meteorite crashed through a house in Atlanta, Georgia, on June 26, narrowly missing the homeowner. Witnessed by hundreds, the fireball streaked across the sky before fragments penetrated the roof and ceiling. Planetary geologist Scott Harris retrieved samples for analysis, revealing the meteorite's origins in the asteroid belt, dating back 4.56 billion years, and potentially linked to the breakup of a larger asteroid.Origins of Asteroids Bennu and RyuguRecent research suggests that both Bennu and Ryugu may share a common ancestry, originating from the same collisional family of asteroids known as Polana. Spectral data comparisons indicate similarities between these asteroids, supporting the hypothesis that they were formed from the remnants of a larger body that fragmented early in the solar system's history. This discovery opens new avenues for understanding the evolution of these near-Earth asteroids.www.spacetimewithstuartgary.com✍️ Episode ReferencesAstrophysical Journal Lettershttps://iopscience.iop.org/journal/2041-8205Planetary Science Journalhttps://www.cambridge.org/core/journals/planetary-science-journalBecome a supporter of this podcast: https://www.spreaker.com/podcast/spacetime-space-astronomy--2458531/support.

• Cosmic Encounters: Asteroids, Moons, and the Milky Way's Future Unveiled

  This episode of SpaceTime is brought to you with the support of Insta360. Capture your adventures with their latest game-changer, the GoUltra. For a special offer, visit store.insta360.com and use the promo code SPACETIME at checkout.In this episode of SpaceTime, we explore thrilling recent discoveries and events in the cosmos, including close encounters with asteroids, a newly discovered moon around Uranus, and the cosmic dance of dwarf galaxies.Earth Dodges Two Asteroid Near MissesPlanet Earth has narrowly avoided two asteroid near misses within days of each other. The first, asteroid 2025 PF2, zipped past at an altitude of just 22,000 kilometers, while the second, 2025 PU1, came even closer at 29,000 kilometers. Both asteroids, small yet significant, highlight the ongoing risks posed by near-Earth objects, with 2025 PU1 being particularly alarming as it was only detected hours after its closest approach.A New Moon for UranusAstronomers have identified a new moon orbiting Uranus, bringing the total number of known satellites to 26. Detected using NASA's Webb Space Telescope, this moon, estimated to be about 10 kilometers in diameter, eluded previous observations, including those from the Voyager 2 mission. Its discovery adds to the complexity of Uranus's moon system and raises questions about the chaotic history of its rings and satellites.Dancing Dwarf Galaxies and the Milky Way's FateA new study suggests that the fate of our Milky Way galaxy is intricately tied to the gravitational interactions with smaller dwarf galaxies as it approaches a merger with the Andromeda galaxy. By studying similar galactic systems, researchers aim to predict how these cosmic dances will influence the evolution of our galaxy over the next few billion years, providing insights into dark matter and cosmic structure.www.spacetimewithstuartgary.com✍️ Episode ReferencesMonthly Notices of the Royal Astronomical Societyhttps://academic.oup.com/mnrasNASA's Webb Space Telescopehttps://www.nasa.gov/mission_pages/webb/main/index.htmlBecome a supporter of this podcast: https://www.spreaker.com/podcast/spacetime-space-astronomy--2458531/support.

• The Comet That Cooled the Earth - Unpacking the Younger Dryas Mystery

  In this episode of SpaceTime, we delve into intriguing new research that challenges our understanding of Earth's climatic history, the discovery of a rare astronomical phenomenon, and China's advancements in lunar exploration.Did a Comet Trigger the Younger Dryas Cool Off?A groundbreaking study has emerged suggesting that a massive comet may have instigated Earth's Younger Dryas cool off event, traditionally attributed to glacial meltwater. Analysis of ocean sediments published in the journal PLOS One reveals geochemical clues that support the hypothesis of Earth encountering a disintegrating comet around 12,800 years ago. This event could have led to rapid cooling, with temperatures plummeting by approximately 10 degrees Celsius within a year. The findings indicate a potential link between comet dust and significant climate shifts, inviting further investigation into this captivating theory.Discovery of a Rare White Dwarf Merger RemnantAstronomers have identified an ultra-massive white dwarf star resulting from the merger of two stars, rather than the evolution of a single star. This discovery, made possible by NASA's Hubble Space Telescope, suggests that such white dwarf mergers may be more common than previously thought. The object, catalogued as WD0525 526, is located 126 light years away and is about 20% more massive than our Sun. Hubble's ultraviolet observations revealed carbon in its atmosphere, a sign of its violent origin, challenging previous assumptions about white dwarf formation.China Tests Its New Manned Lunar LanderIn a significant milestone for lunar exploration, China has successfully conducted a test flight of its new manned lunar landing craft, named Lanyu. This test, which included a controlled landing and takeoff, marks a crucial step in China's ambitions to send taikonauts to the Moon by 2030. The Lanyu is designed to carry astronauts from lunar orbit to the surface and back, with plans for a permanent lunar base in collaboration with Russia in the early 2030s.www.spacetimewithstuartgary.com✍️ Episode ReferencesPLOS Onehttps://journals.plos.org/plosone/Nature Astronomyhttps://www.nature.com/natureastronomy/NASA Hubble Space Telescopehttps://www.nasa.gov/mission_pages/hubble/main/index.htmlBecome a supporter of this podcast: https://www.spreaker.com/podcast/spacetime-space-astronomy--2458531/support.
