Podcasts about Cassini

April 23, 2026 - Equipped 2026 - Day 1 - 6:30 PM Session   Room:  Auditorium Title:  In The Beginning Speaker:  Steve Higginbotham Summary: The lecture by Steve Higginbotham seeks to rekindle awe for God's power and greatness by examining His creation. The speaker argues that modern society often overlooks God's work, becoming more impressed by human achievements like the pyramids of Giza. He contrasts the vastness of the universe (macrocosm) with the complexity of microscopic life (microcosm). Using examples such as Cassini's photo of Earth, the James Webb Telescope's Ultra Deep Field image, the finely tuned Earth–Moon system, and microscopic creatures like the hydrothermal worm and the resilient tardigrade, he underscores God's immense power and intelligent design. He also explores DNA's complexity to showcase God's wisdom at the cellular level. The core message is that creation is a form of natural revelation, universally testifying to God's existence and glory, urging people to seek Him. The lecture concludes by asserting that God's ultimate display of wisdom is not nature, but the creation of the Church.   Duration 28:14

Ricky Cassini, CEO of Michroma and a former logistics professor turned biotech founder, breaks down why replacing synthetic food dyes is harder than it sounds—and why fermentation-based colorants can outperform both petrochemical dyes and many plant-based “natural” extracts. The conversation covers the core technical constraints that matter to food companies (thermal stability, pH stability, coloring power, flavor neutrality, and supply reliability), why fermentation behaves more like manufacturing than farming, and how regulatory shifts are accelerating demand for bio-based reds and whites (including titanium dioxide alternatives). For an audience following the future of materials and biomanufacturing, this episode is a practical look at how industrial fermentation can modernize a legacy supply chain while meeting performance and consumer expectations.Grow Everything brings the bioeconomy to life. Hosts Karl Schmieder and Erum Azeez Khan share stories and interview the leaders and influencers changing the world by growing everything. Biology is the oldest technology. And it can be engineered. What are we growing?Learn more at ⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠www.messaginglab.com/groweverything⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠Chapters:(00:00:00) Cold open: “Are we eating printing ink?” + beverage innovation(00:06:55) Conference mode + introducing Ricky Cassini (Michroma)(00:11:05) How a strategy consultant became a fungal pigments CEO(00:14:10) Pigment vs dye: soluble vs dispersed (coffee analogies)(00:16:05) The “food contradiction”: healthy intent, petrochemical reality(00:18:40) Why plant-based reds struggle (cost, stability, supply chain)(00:22:35) Pricing confusion: cost per kilo vs cost-in-use (paint analogy)(00:26:05) What colors Michroma is starting with (red, yellow/orange, white)(00:28:05) Performance specs that matter: heat, pH, light, flavor, reliability(00:30:05) Labeling: “Red 40 / Yellow 5” vs natural naming + how novel fermented colors may be listed(00:33:05) Go-to-market: choosing categories where stability is the bottleneck (dairy, bakery, snacks, vitamins)(00:35:15) Unexpected use cases: aquaculture (salmon) + packaging inks that can migrate into food(00:36:55) Manufacturing strategy: partnering with CJ vs building plants; “time compression” and capex discipline(00:38:10) Scaling pressure points: regulatory timeline + the time/capital reality for novel ingredients(00:39:45) 5–10 year vision: same bright foods, but colors made via microbes (supply chain shift)(00:40:35) Quickfire round: fluorescent food-grade pigments, Gantt charts, and GMO marketing(00:41:40) Wrap + host outro + upcoming episodes and partner promoLinks and Resources:michromaMichroma says fermentation will power next wave of natural colors2025 1st Place Winner of The Future is Fungi Awards159. The Future Is Fungi Awards: From Mushroom Dreams to Real-World ThingsCJ bio - Global FermentationWorld Bio Markets - Our new partnersBioInnovations Events - For 25% off use code: Grow EverythingWorld Bio Markets - PodcastsMars SnackingMolecule Manifesto - Advanced Biotech for Sustainability ReportTickets for the GE Live Event with Roebling Topics Covered:fungi pigments, bio-based colorants, fungal dyes, natural pigments, sustainable color, food colorants, synthetic dyes alternatives, antioxidant pigments, food and beverage, clean ingredientsHave a question or comment? Message us here:Text or Call (804) 505-5553⁠⁠⁠⁠⁠⁠⁠⁠Instagram⁠⁠⁠⁠⁠⁠⁠⁠ / ⁠⁠⁠⁠⁠⁠⁠⁠Twitter⁠⁠⁠⁠⁠⁠⁠⁠ / ⁠⁠⁠⁠⁠⁠⁠⁠LinkedIn⁠⁠⁠⁠⁠⁠⁠⁠ / ⁠⁠⁠⁠⁠⁠⁠⁠Youtube⁠⁠⁠⁠⁠⁠⁠⁠ / ⁠⁠⁠⁠⁠⁠⁠⁠Grow Everything⁠⁠⁠⁠⁠⁠⁠⁠Music by: Nihilore Production by: Amplafy Media

www.aufonddelaclasse.comLes Entretiens sur la pluralité des mondes de Fontenelle paraissent en 1686. Leur auteur, né en 1657 et mort centenaire en 1757, est un homme de frontières : entre littérature et science, entre le classicisme du Grand Siècle et les Lumières à venir. Le livre connaîtra trente-trois éditions de son vivant.Le principe est simple : six soirées de conversation entre un philosophe et une marquise, dans le parc d'un château. Chaque soir, ils s'avancent un peu plus loin dans l'univers — la Terre, la Lune, les planètes, les étoiles fixes, l'infini. Le contenu scientifique est sérieux : système de Copernic, tourbillons de Descartes, pluralité des mondes. Mais tout cela est dit sur le ton du badinage galant, avec des métaphores, de l'humour, de la légèreté.Pour comprendre ce choix, il faut replacer le livre dans son contexte. Au XVIIe siècle, la curiosité scientifique est encore suspecte : Augustin la condamnait comme péché, Pascal tremblait devant « le silence éternel de ces espaces infinis ». En même temps, la révolution scientifique de Galilée, Descartes et Cassini a bouleversé la vision de l'univers. Fontenelle veut faire entrer ces idées nouvelles dans les salons aristocratiques — un monde régi par le bon goût, la conversation et l'élégance.Son projet se résume dans une phrase de la Préface : « Il n'y a pas jusqu'aux vérités à qui l'agrément ne soit nécessaire. » Le plaisir n'est pas un ornement ajouté à la science — il en est une condition. Comprendre doit être jouissif.C'est tout le sens du parcours « Le goût de la science » : comment Fontenelle fait-il du désir de savoir une forme de séduction, et de la transmission scientifique un art à part entière ?Hébergé par Ausha.

Could there really be life on Enceladus?Enceladus' ocean is far more active than we thought. New images from the James Webb Space Telescope revealed the largest plume ever seen erupting from the tiny moon's frozen surface. Deep diving into Cassini data, scientists have uncovered the chemistry hiding in the depths of the subsurface ocean… and it's more complex and shocking than anyone imagined. Is this small moon the most likely home for life beyond Earth?▀▀▀▀▀▀If you love learning about science as much as I do, head to http://brilliant.org/astrum to learn for free for a full 30 days.

Наблюдение на Земята (или Earth Observation) звучи доста ясно само по себе си. Разбира се, това е начинът, по който гледаме към суша, вода, градове, земеделие и инфраструктура от орбита - с малката добавка, че целта е да видим как това да е всъщност полезно. В този епизод със Здравко Димитров и Майкъл Цанев говорим за това защо ни трябват нови сателити, къде днес са границите на резолюцията и защо в много случаи по-важно от това колко ясно виждаме е колко често можем да заснемаме. Отваряме и съвсем конкретния въпрос как се достъпват сателитни данни, кои са свободни, кои се купуват, кой реално може да си ги позволи и докъде стига популярната представа, че можем просто да си гледаме вилата от космоса. Обсъждаме какво всъщност могат да разпознаят съвременните системи, какви ограничения още има пред технологията и защо стойността на данните все по-често идва не само от самото изображение, а от анализа върху него. Майкъл разказва и за пътя на своя екип в CASSINI Hackathon 2025, където Avalanche Detectors печели с решение, което комбинира Copernicus Sentinel-1 и Sentinel-2 с метеорологична информация, за да изчислява вероятност от лавина на конкретно място. Епизодът е и естествена прелюдия към 11-ия CASSINI Hackathon, който ще се проведе между 24 и 26 април 2026 г. едновременно на 10 места в Европа, включително София, с тема Space for Water. За България това е и доста релевантна дейност, предвид наводнения през последните години, водните загуби, недостиг и управление на риск при водите . Тук именно космическите данни мога да помогнат. Запишете се тук: https://www.cassini.eu/hackathons/bulgaria В епизода говорим още за: • какво точно означава Earth Observation • защо новите приложения изискват по-чести заснемания, а не само по-добра резолюция • как се купуват и използват сателитни данни днес • кой има достъп до тях и как това се променя • какви са реалните ограничения пред граждански и бизнес приложения • какво може да се постигне в рамките на един хакатон, когато имаш данни, ментори и добре формулиран проблем

Right after his keynote at the Applied Ergonomics Conference, we had a chance to sit down with Cassini Nazir, an interaction designer and professor at the University of North Texas. In his talk, Cassini encouraged ergonomics professionals to think more intentionally about curiosity and how asking better questions and designing with empathy can improve the systems and experiences people rely on every day.And as it happened, his friend Mike Courtney was there too. Mike is a futurist who actually delivered the keynote at last year's conference, so we talked with him about something many professionals are dealing with right now - the rapid pace of technological change and how to make decisions when things are evolving so quickly.Two quick conversations, both recorded at the Applied Ergonomics Conference, about curiosity, design, and navigating a changing world.This bonus episode was recorded live at the Applied Ergonomics Conference as part of Problem Solved LIVE.Every great solution is a story worth telling.Applied Ergonomics Conference sponsored by Applied Ergonomics SocietyLearn more about The Institute of Industrial and Systems Engineers (IISE)Problem Solved on LinkedInProblem Solved on YouTubeProblem Solved on InstagramProblem Solved on TikTokProblem Solved Executive Producer: Elizabeth GrimesInterested in contributing to the podcast or sponsoring an episode?

SpaceTime with Stuart Gary Gary - Series 29 Episode 21In this episode of SpaceTime, we explore intriguing revelations about the search for life on Mars, the surprising effects of Saturn's moon Enceladus on its planet, and the monumental volcanic events that reshaped Earth's tectonic landscape.Life on Mars: A New PerspectiveRecent findings suggest that non-biological processes cannot fully explain the organic compounds found in Martian regolith samples collected by NASA's Curiosity rover. Published in the journal Astrobiology, the study indicates that life may have contributed to some of these compounds, challenging previous assumptions. The research involved evaluating potential non-biological sources and concluded that the abundance of organics on Mars could hint at past life, sparking renewed interest in the Red Planet's potential habitability.Enceladus' Electromagnetic InfluenceA fascinating study reveals that Saturn's icy moon Enceladus trails a wake of electromagnetic ripples extending over half a million kilometers, significantly influencing its giant host planet. Data from NASA's Cassini mission demonstrated how Enceladus' geysers contribute to energy and momentum circulation within Saturn's magnetic environment, marking a crucial discovery about the moon's role in the Saturnian system.Earth's Volcanic HistoryNew research highlights how Earth's largest volcanic event, associated with the Ontong Java Plateau, dramatically altered a major tectonic plate. The findings suggest that extensive volcanic activity led to significant physiochemical modifications within the oceanic plate, enhancing our understanding of plate formation processes and the environmental impacts of such massive eruptions.www.spacetimewithstuartgary.com✍️ Episode ReferencesAstrobiology, Geophysical Research Space Physics, Geophysical Research LettersBecome a supporter of this podcast: https://www.spreaker.com/podcast/spacetime-with-stuart-gary--2458531/support.

https://www.youtube.com/watch?v=-Alz4UXGqLk From March 8, 2017. In just a few months, NASA's Cassini spacecraft is going to die, crashing into the planet Saturn. Let's look back across the mission's history. What were the highlights? What did we learn?   Team: Fraser Cain - @fcain / frasercain@gmail.com Karla Thompson - @karlaii Chad Weber - weber.chad@gmail.com   Ask me my favorite object in the Solar System, especially to see through a telescope, and my answer is always the same: Saturn. Saturn is this crazy, ringed world, different than any other place we've ever seen. And in a small telescope, you can really see the ball of the planet - you can see its rings.   We've added a new way to donate to 365 Days of Astronomy to support editing, hosting, and production costs.  Just visit: https://www.patreon.com/365DaysOfAstronomy and donate as much as you can!

Sous le commandement de Donald Trump, l'opération « Absolute Resolve » (Détermination Absolue) au Venezuela a créé une onde de choc mondiale avec des conséquences économiques majeures, bien au-delà des questions pétrolières et énergétiques. Pour la Chine (partenaire historique de Caracas), les autres BRICS, les potentielles cibles américaines (Groenland, Canada, Cuba) et les investisseurs du monde entier, un océan d'incertitudes se profile. Éco d'ici Éco d'ailleurs donne la parole aux experts. Les invités de l'émission Christopher Dembik, macroéconomiste, conseiller en stratégie d'investissement chez Pictet Asset Management Alicia Garcia-Herrero, cheffe économiste pour la zone Asie-Pacifique de la Banque Natixis (basée à Hong-Kong) Philippe Sébille-Lopez, directeur du cabinet Géopolia, spécialiste des marchés pétroliers Margot François, chercheuse à l'Institut français de géopolitique et analyste chez Cassini, experte de l'économie cubaine Cléa Broadhurst, correspondante permanente de RFI à Pékin   Le pétrole vénézuélien : un eldorado complexe Des réserves impressionnantes mais problématiques Le Venezuela possède théoriquement 300 milliards de barils de réserves, principalement dans le fleuve Orénoque, ce qui le placerait au premier rang mondial. Cependant, ces chiffres sont contestés et peu vérifiables. Les défis du pétrole vénézuélien Huile extra-lourde : très visqueuse et très soufrée, nécessitant un traitement particulier Coûts élevés : investissements nécessaires entre 60 et 80 dollars par baril Infrastructure vétuste : années de sous-investissement sous sanctions Raffinage complexe : vendu avec une forte décote sur le marché Un intérêt stratégique pour les États-Unis L'outil de raffinage américain est équipé à 70% pour traiter du brut lourd. Le pétrole vénézuélien correspond parfaitement à ces installations, ce qui explique l'intérêt stratégique au-delà de la simple production. « Nous avons construit l'industrie pétrolière vénézuélienne grâce au talent, au dynamisme et aux compétences des Américains. Et le régime socialiste nous l'a volé en recourant à la force. » - Donald Trump La dimension géopolitique Avant l'intervention, 80% de la production vénézuélienne partait vers la Chine. La Russie, via Rosneft, était également très présente. Pour Washington, il s'agit autant de reprendre le contrôle que d'empêcher les concurrents d'y accéder. Impact sur la Chine : premier acheteur menacé Une relation économique majeure en péril La Chine avait prêté environ 60 milliards de dollars au régime vénézuélien, principalement sous Chavez, sous forme de prêts gagés sur des productions futures de brut. Les compagnies chinoises étaient devenues les principaux acheteurs du pétrole vénézuélien. Conséquences immédiates Le pétrole vénézuélien arrivant en Chine est déjà vendu avec des rabais et passe par des circuits logistiques compliqués. Si Washington bloque ou inspecte les cargaisons, les coûts augmenteront considérablement : assurances plus chères, délais plus longs, risques juridiques accrus. Les raffineurs indépendants chinois, appelés « teapots », qui vivent sur les marges, seront particulièrement touchés. Le baril vénézuélien devient « un baril plus compliqué et plus cher ». « La Chine est profondément choquée et condamne fermement l'utilisation éhontée de la force contre un État souverain. Cela constitue une violation grave du droit international. »- Porte-parole du gouvernement chinois Révision stratégique en Amérique latine L'intervention envoie un signal clair à toute la région. Les gouvernements et entreprises doivent désormais calculer : « Si je fais un gros deal chinois dans un secteur sensible, est-ce que j'attire une pression américaine ? » La Chine ne va pas abandonner l'Amérique latine facilement. La région représente des investissements de près de 200 milliards de dollars dans les minéraux critiques, terres rares, or et argent. Cuba : une économie au bord du précipice Une crise structurelle aggravée L'économie cubaine, déjà en crise permanente depuis la chute de l'URSS, risque le coup fatal. Cuba dépend fortement du pétrole vénézuélien pour son système énergétique vétuste.

Sous le commandement de Donald Trump, l'opération « Absolute Resolve » (Détermination Absolue) au Venezuela a créé une onde de choc mondiale avec des conséquences économiques majeures, bien au-delà des questions pétrolières et énergétiques. Pour la Chine (partenaire historique de Caracas), les autres BRICS, les potentielles cibles américaines (Groenland, Canada, Cuba) et les investisseurs du monde entier, un océan d'incertitudes se profile. Éco d'ici Éco d'ailleurs donne la parole aux experts. Les invités de l'émission Christopher Dembik, macroéconomiste, conseiller en stratégie d'investissement chez Pictet Asset Management Alicia Garcia-Herrero, cheffe économiste pour la zone Asie-Pacifique de la Banque Natixis (basée à Hong-Kong) Philippe Sébille-Lopez, directeur du cabinet Géopolia, spécialiste des marchés pétroliers Margot François, chercheuse à l'Institut français de géopolitique et analyste chez Cassini, experte de l'économie cubaine Cléa Broadhurst, correspondante permanente de RFI à Pékin   Le pétrole vénézuélien : un eldorado complexe Des réserves impressionnantes mais problématiques Le Venezuela possède théoriquement 300 milliards de barils de réserves, principalement dans le fleuve Orénoque, ce qui le placerait au premier rang mondial. Cependant, ces chiffres sont contestés et peu vérifiables. Les défis du pétrole vénézuélien Huile extra-lourde : très visqueuse et très soufrée, nécessitant un traitement particulier Coûts élevés : investissements nécessaires entre 60 et 80 dollars par baril Infrastructure vétuste : années de sous-investissement sous sanctions Raffinage complexe : vendu avec une forte décote sur le marché Un intérêt stratégique pour les États-Unis L'outil de raffinage américain est équipé à 70% pour traiter du brut lourd. Le pétrole vénézuélien correspond parfaitement à ces installations, ce qui explique l'intérêt stratégique au-delà de la simple production. « Nous avons construit l'industrie pétrolière vénézuélienne grâce au talent, au dynamisme et aux compétences des Américains. Et le régime socialiste nous l'a volé en recourant à la force. » - Donald Trump La dimension géopolitique Avant l'intervention, 80% de la production vénézuélienne partait vers la Chine. La Russie, via Rosneft, était également très présente. Pour Washington, il s'agit autant de reprendre le contrôle que d'empêcher les concurrents d'y accéder. Impact sur la Chine : premier acheteur menacé Une relation économique majeure en péril La Chine avait prêté environ 60 milliards de dollars au régime vénézuélien, principalement sous Chavez, sous forme de prêts gagés sur des productions futures de brut. Les compagnies chinoises étaient devenues les principaux acheteurs du pétrole vénézuélien. Conséquences immédiates Le pétrole vénézuélien arrivant en Chine est déjà vendu avec des rabais et passe par des circuits logistiques compliqués. Si Washington bloque ou inspecte les cargaisons, les coûts augmenteront considérablement : assurances plus chères, délais plus longs, risques juridiques accrus. Les raffineurs indépendants chinois, appelés « teapots », qui vivent sur les marges, seront particulièrement touchés. Le baril vénézuélien devient « un baril plus compliqué et plus cher ». « La Chine est profondément choquée et condamne fermement l'utilisation éhontée de la force contre un État souverain. Cela constitue une violation grave du droit international. »- Porte-parole du gouvernement chinois Révision stratégique en Amérique latine L'intervention envoie un signal clair à toute la région. Les gouvernements et entreprises doivent désormais calculer : « Si je fais un gros deal chinois dans un secteur sensible, est-ce que j'attire une pression américaine ? » La Chine ne va pas abandonner l'Amérique latine facilement. La région représente des investissements de près de 200 milliards de dollars dans les minéraux critiques, terres rares, or et argent. Cuba : une économie au bord du précipice Une crise structurelle aggravée L'économie cubaine, déjà en crise permanente depuis la chute de l'URSS, risque le coup fatal. Cuba dépend fortement du pétrole vénézuélien pour son système énergétique vétuste. La situation cubaine Dépendance énergétique : les livraisons vénézuéliennes étaient déjà réduites depuis 2017 Réseau électrique défaillant : coupures de courant quotidiennes, en province on parle "d'allumage de courant" Crise démographique : population passée de 11,2 millions à 9,75 millions (voire 8 millions selon des observateurs) Exode massif : 850 000 Cubains entrés aux États-Unis entre 2021 et 2023 « Cuba est un désastre.

Ilaria apre la puntata parlando di endometriosi, una patologia infiammatoria cronica che colpisce circa il 10–11% delle donne in età riproduttiva, ma che continua a essere poco compresa e fortemente sottofinanziata. Per anni l'endometriosi è stata considerata quasi esclusivamente una malattia ormono-dipendente; oggi, però, nuovi studi suggeriscono che il sistema immunitario giochi un ruolo chiave fin dalle primissime fasi. In particolare, un modello patogenetico a due fasi mostra come neutrofili e macrofagi possano favorire l'attecchimento delle lesioni prima ancora che entrino in gioco gli estrogeni, aprendo la strada a nuove prospettive diagnostiche e terapeutiche.Nell'esterna, Giuliana ci porta fuori dallo studio per affrontare una domanda solo apparentemente paradossale: perché dimenticare è importante? A rispondere è Sergio Della Sala, professore di neuroscienze cognitive umane all'Università di Edimburgo, che spiega come l'oblio non sia un difetto del cervello, ma una funzione fondamentale per filtrare le informazioni, ridurre il sovraccarico cognitivo e rendere la memoria davvero efficiente.A chiudere la puntata è Andrea, che ci porta lontano dalla Terra, su Titano, la luna più grande di Saturno. Una nuova rianalisi dei dati della missione Cassini suggerisce che il celebre oceano sotterraneo ipotizzato per anni potrebbe non esistere. Al suo posto, l'energia mareale sembrerebbe dissiparsi in uno strato di ghiaccio ad alta pressione, forse “slushy”, con sacche di acqua liquida. Sarà la futura missione Dragonfly a dirci se Titano ha ancora qualche sorpresa da svelare.Diventa un supporter di questo podcast: https://www.spreaker.com/podcast/scientificast-la-scienza-come-non-l-hai-mai-sentita--1762253/support.

Not many planetary spacecraft get to shower off. But the Cassini spacecraft did – more than once. It flew through plumes of ice and water vapor from Enceladus, a moon of Saturn. The encounters helped scientists confirm that an ocean hides below the moon’s icy crust. Enceladus is a little more than 300 miles in diameter – roughly the distance from Los Angeles to San Diego. Its surface is completely coated with ice. That makes it the most reflective large body in the solar system, so it looks bright white. Much of that ice comes from more than a hundred geysers near the moon’s south pole. They erupt from deep cracks in the crust. They contain water vapor, water ice, hydrogen, grains of salt, and other compounds. Much of this material falls back on the surface. The rest of it escapes into space, where it forms a thin ring around Saturn. The geysers erupt from a global ocean. It’s buried about 20 to 25 miles below the surface, and it could be 10 miles deep or more. Hot, mineral-rich water could flow into the ocean through fissures on its floor. So the ocean appears to offer all the ingredients for life: liquid water, minerals, and a source of heat. That makes Enceladus a high-priority target in the hunt for life beyond Earth. Saturn is near our own moon this evening. It looks like a bright star, shining steadily through the lunar glare. But you need a good-sized telescope to pick out Enceladus.

SpaceTime with Stuart Gary Gary - Series 28 Episode 150In this episode of SpaceTime, we delve into intriguing discoveries and ongoing challenges in the realm of astrophysics and planetary science.Cosmic Dance of Dying StarsAstronomers have made fascinating observations of a unique star system named Apep, located over 8,000 light years away in the constellation Norma. This rare system consists of three massive stars locked in a 190-year orbit, creating stunning spirals of cosmic dust. Using the advanced capabilities of NASA's Webb Space Telescope and the Very Large Telescope in Chile, researchers captured extraordinary images revealing four distinct dust shells spiraling outward from the stars. Lead author Ryan White from Macquarie University discusses how these findings enhance our understanding of stellar interactions and the evolution of massive stars over time.Titan's Liquid Ocean: A New PerspectiveA recent study challenges the long-held belief that Saturn's largest moon, Titan, harbors a vast underground ocean. Instead, researchers suggest that Titan may have a more complex internal structure characterized by slushy tunnels and pockets of meltwater rather than a global liquid water ocean. This revelation, based on a reanalysis of data from NASA's Cassini mission, could have significant implications for the search for potential life on Titan, indicating that any existing life forms might inhabit a more confined environment with concentrated nutrients.NASA's MAVEN: Communication ChallengesMission managers at NASA are working diligently to restore contact with the Mars Atmosphere and Volatile Evolution (MAVEN) spacecraft, which went silent during a routine pass behind Mars on December 6. Engineers are analyzing data from before the loss of signal to identify the cause and determine if the spacecraft can be salvaged. MAVEN has been crucial for studying Mars' atmosphere and has served as a vital communications relay for surface missions.www.spacetimewithstuartgary.com✍️ Episode ReferencesAstrophysical JournalNatureNASA TVBecome 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 28 episode 150 for broadcast on 22nd December 2025(00:00:47) NASA's Webb Space Telescope reveals four spectacular dust shells from distant star system(00:10:58) New study says Titan probably doesn't have a vast underground liquid water ocean(00:15:57) NASA mission managers continue efforts to restore contact with missing maven spacecraft(00:18:36) New study finds shared genetic patterns across 14 common psychiatric disorders(00:20:56) A new study claims acupuncture treatment for lower back pain reduces pain

In this episode, we journey through a captivating array of discoveries and cosmic events that challenge our understanding of the universe. We kick off with a surprising revelation about Titan, Saturn's largest moon, where new analysis suggests its interior may be a thick, warm slush rather than a vast ocean, complicating the search for extraterrestrial life. Next, we discuss a recent anomaly involving SpaceX's Starlink satellites that resulted in a satellite breaking apart, raising concerns about space debris and its implications for future missions.Shifting gears, we delve into the implications of President Trump's executive order on national space policy, which aims for a 2028 moon landing and addresses the increasing militarization of space. We then unravel the mystery of Fomalhaut B, once thought to be an exoplanet, but now revealed to be a cloud of debris from a cosmic collision, providing insight into the chaotic processes of planet formation.As we explore the interstellar comet 3I ATLAS making its closest approach to Earth, we highlight the fleeting opportunity for scientists to study this visitor from another solar system. Finally, we celebrate the Spherex Space Telescope's completion of its first all-sky infrared map, which promises to answer fundamental questions about the universe's structure and the origins of life.### Timestamps & Stories01:05 – **Story 1: Surprising Discovery about Titan****Key Facts**- New analysis suggests Titan's interior may be a thick, warm slush instead of a vast ocean.- This alters the prospects for extraterrestrial life.03:20 – **Story 2: SpaceX's Starlink Anomaly****Key Facts**- A Starlink satellite experienced an anomaly, breaking apart and creating debris.- The satellite is expected to deorbit and burn up in the atmosphere soon.05:45 – **Story 3: National Space Policy Changes****Key Facts**- President Trump's executive order aims for a 2028 moon landing and addresses space security.- The order reinforces NASA's Artemis program and emphasizes sustainable lunar presence.08:00 – **Story 4: The Mystery of Fomalhaut B****Key Facts**- Fomalhaut B was revealed to be a cloud of debris from a cosmic collision, not a planet.- This discovery offers a real-time look at planetary system formation.10:15 – **Story 5: Interstellar Comet 3I ATLAS Approaches Earth****Key Facts**- The comet is making its closest approach, providing a rare observational opportunity.- It is too faint for the naked eye but can be tracked online.12:00 – **Story 6: Spherex Telescope's All-Sky Map****Key Facts**- The Spherex Space Telescope has completed its first all-sky infrared map in 102 colors.- This map will help answer questions about the universe's structure and the origins of life.### Sources & Further Reading1. NASA2. SpaceX3. James Webb Space Telescope4. European Space Agency5. Space.com### Follow & ContactX/Twitter: @AstroDailyPodInstagram: @astrodailypodEmail: hello@astronomydaily.ioWebsite: astronomydaily.ioClear skies and see you next time!

Hoy, Jorge Laborda habla de la posibilidad de regenerar el corazón tras un infarto. Explica cómo la activación controlada de un gen concreto permite que las células cardíacas adultas vuelvan a dividirse, algo que hasta ahora se creía imposible. Experimentos con células de donantes de más de 40 años demostraron divisiones completas y funcionales sin activar otros tejidos, abriendo la puerta a terapias capaces de reparar el daño del corazón después de un infarto. Por su parte, Ángel Rodríguez Lozano aborda la búsqueda de vida en Encélado, una luna de Saturno. Los datos de la misión Cassini y un estudio reciente respaldan la existencia de un océano global activo bajo la capa de hielo que la recubre. La presencia de compuestos orgánicos, hidrógeno y sílice en los géiseres que emergen por las grietas de la superficie sugiere la existencia de procesos hidrotermales similares a los que, en la Tierra, albergan ecosistemas ricos en vida.

Dr. Alfonso Davila (NASA Ames Research Center)Nov. 24, 2025In 2005, NASA's Cassini spacecraft made a groundbreaking discovery—it found massive plumes of ice and gas erupting from the south pole of Enceladus, a small but geologically-active moon of Saturn. These plumes are now believed to originate from a subsurface ocean of liquid water beneath the moon's icy crust, with conditions compatible with life, as we know it. The talk focuses on our current understanding of Enceladus' plume and subsurface ocean, and on past and future strategies to search in them for possible evidence of life.  Alfonso Davila is a Research Scientist in the Exobiology branch at NASA Ames Research Center, where he helps develop strategies to search for evidence of life beyond Earth.

How do planetary ring systems rings form, and what keeps them in line? What exactly is the Dragon Cloud of Saturn? And what's up with quasi moon 2025 PN7? To find out, Dr. Charles Liu and co-host Allen Liu welcome Cornell University's dynamical astronomer Dr. Phil Nicholson for a refresher course in orbital mechanics. As always, though, we start off with the day's joyfully cool cosmic thing, which is right up Phil's alley: the recent discovery of quasi moon 2025 PN7. Phil unpacks the orbital mechanics to explain the critical differences between quasi moons and regular moons, and also 2025 PN7's strange relationship to Earth's orbit. He also explains the dynamics of the sun's tidal forces and Earth's Hill Sphere. For our first question from the audience, Jameson asks, “Are meteorites smaller copies of planets. Are all of them the same?” Rather than discuss meteorites, which are the tiny survivors that have crashed on Earth, Phil pivots to where many of them come from in the first place: asteroids. Really big asteroids share some characteristics with planets, like being spherical in shape, whereas the smaller ones can be highly irregular, like the dumbbell-shaped asteroid 216 Kleopatra, or Arrokoth, previously known as Ultima Thule. Chuck asks Phil about the different shapes large asteroids can come in, and Phil points out 433 Eros, the second largest Near Earth Object, which is banana shaped. The ensuing brief discussion of the “is it a long, skinny asteroid or an interstellar starship?” debate, like the one sparked by Oumuamua, leads to a conversation about Arthur C. Clarke's “Rendezvous with Rama”, which described just such a starship back in 1973. Somehow, we end up looking at the “face” on Mars and the “Death Star,” aka, Saturn's moon Mimus as it was imaged by the Cassini spacecraft. Phil actually worked on the Cassini mission, and Chuck asks him to talk about his experience peering hundreds of miles deep into Saturn's atmosphere with the spacecraft's Visible and Infrared Mapping Spectrometer (VIMS). Along with other instruments run by other teams, the mission changed our perception of Saturn's “boring” atmosphere, documenting aurora, lightning, and giant storms like the “Dragon Cloud of Saturn.” Our next student question comes from Marvin, who asks, “What exactly is a Shepherd moon?” To answer, Phil describes what Saturn's rings are made of, how they form, and how they're structured. He explains what happens when particles that make up the rings collide, why some rings spread over time, while others stay very narrow, and the role Shepherd satellites play in the process. We end with Chuck soliciting a few classic sci-fi recommendations from Phil, who suggests anything by Arthur C. Clarke, the Foundation Trilogy by Isaac Asimov, and almost anything by Larry Niven, including Ringworld, his most famous series.

It’s pretty easy to measure the length of a day on Mars or most other solid bodies. Just pick a feature on the surface and see how long it takes to spin back into view. It’s not so easy for planets that don’t have a solid surface. We can track bands of clouds, but different bands can move at different speeds. That’s been an especially tough problem for Saturn, the second-largest planet in the solar system. Scientists have been trying to pin down its rotation rate – the length of its day – for centuries. When the twin Voyager spacecraft flew past Saturn in the 1980s, they measured the planet’s magnetic field to reveal the rotation rate of its interior. But when the Cassini spacecraft orbited Saturn decades later, its observations showed the day was about six minutes longer. At the end of its mission, Cassini flew between Saturn and the inner edge of its rings. Measuring waves in the rings and tiny changes in the planet’s gravitation field produced yet another length: 10 hours, 33 minutes, and 38 seconds. That’s not necessarily the final answer. Scientists continue to study the giant planet to know how to set their Saturn clocks. And Saturn is in great view tonight. It looks like a bright star quite close to the lower right of the Moon at nightfall, and below the Moon as they set, before dawn. Script by Damond Benningfield

In Plain Sight: A Memoir Infused with Military Psychological Operationsis the raw, introspective autobiography of Jonathan Mark Haber, a Brooklyn-born activist whose relentless quest for truth spans government conspiracies, military psy-ops, and spiritual awakening.The narrative begins in 1960s Brooklyn, where the assassinations of JFK, MLK, and RFK, the Vietnam War, and nuclear brinkmanship ignite Haber's activism. From draft resistance and communal living to building a family in rural Massachusetts, each step fuels his resolve to expose hidden forces shaping history.Central to his journey is a spiritual and political awakening guided by mentors like Karl Grossman, Elwood Babbitt, Eckhart Tolle, and Manhattan Project/NASA whistleblower Bart Jordan. Their insights propel his work with Flyby News, where he challenges official narratives—from the Cassini flyby and 9/11 to COVID-19—revealing the pervasive reach of military psychological operations.A defining collaboration with Jordan uncovers evidence of ancient Martian artifacts and languages, suggesting a pre-ice-age warning: humanity must break war's cyclical destruction or face oblivion. (Further details are explored in FlybyNews.com and on YouTube: "Bart Jordan: Manhattan Project NASA Whistleblower.")Interwoven with investigative rigor is Haber's personal battle—chronic pain, kidney failure, and profound loss—met with resilience and a belief in love's transformative power. More than a memoir, In Plain Sight is a call to confront deception and forge a future rooted in peace.https://amzn.to/3ImWDCwBecome a supporter of this podcast: https://www.spreaker.com/podcast/the-opperman-report--1198501/support.

Earth has something in common with Titan, the largest moon of Saturn. They’re the only two bodies in the solar system with liquids flowing and ponding on the surface. In the case of Earth, that liquid is water. But on frigid Titan, it’s liquid hydrocarbons – methane and ethane. Titan is the second-largest moon in the solar system – a bit bigger than the planet Mercury. Its surface is extremely cold – hundreds of degrees below zero. Its atmosphere is thicker than Earth’s, and it’s topped by a dense layer of smog. The Cassini spacecraft used radar to peer through the clouds. And its findings were remarkable. It discovered rivers flowing across the surface, emptying into lakes and seas. It also found clouds, which occasionally produce rain. Everything we can see on Titan contains a lot of carbon-based compounds – some of the raw building blocks of life. That’s led to speculation that Titan might have the precursors to life – or even life itself – hidden in a giant ocean below the crust. To be clear, there’s no evidence of life. But future missions to Titan will sniff around for such evidence – perhaps adding to the list of things that Earth and Titan have in common. Saturn appears quite close to our own moon tonight. It looks like a bright star to the lower left of the Moon as they climb into good view, by about 11 o’clock. But you’ll need a small telescope to pick out Titan. Script by Damond Benningfield

Powering spacecraft, especially out in the dark, cold outer solar system, is a huge challenge. There are limits to how large solar panels can be, and they are not very efficient in the weak sunlight beyond Mars. For decades, choice flagship NASA missions have used RTGs--radioisotope thermoelectric generators--to fill this need. From the experiments on the Apollo missions to the Viking Mars landers, Galileo to Jupiter, Cassini to Saturn, and the twin Voyagers, RTGs have provided decades of power for space exploration. From Plutonium to Americium, nuclear elements provide years and years of heat that can be converted into electricity. Dr. Rob O'Brien is the Director of the Center for Space Nuclear Research for the Universities Space Research Association and has specialized in RTGs for decades. It's a fascinating dive into atomic space batteries! Headlines The End of the Universe is Nigh (in 33 Billion Years): New dark matter discoveries suggest an earlier end to the universe, leading to a humorous discussion about bucket list items. August 2nd "Solar Eclipse": Rumors of an August 2nd, 2025, total solar eclipse are false; the next one on that date is in 2027 that won't darken the entire world, but will be the longest one of the century. Mother Earth 2.0 (L98-59f): Discussion of exoplanet L98-59f, 35 light-years away, and its potential habitability despite orbiting a red dwarf with a 23-day year. NASA Budget Concerns: Senate and House pushback against proposed cuts to NASA's 2026 science mission budget is discussed, with calls to preserve vital research. Mass Exodus at NASA: Senior NASA staff, including scientists and engineers, are reportedly leaving due to budget cuts, raising concerns about future capabilities. Main Topic - Dr. Robert O'Brien & RTGs (Radioisotope Thermoelectric Generators) Understanding RTGs: Dr. O'Brien explains RTGs convert heat from radioactive decay into electricity using the Seebeck effect. Early Use of RTGs in Space: The first US public RTG demonstration was on President Eisenhower's desk, and the first space use was the US Navy's Transit 4A satellite in 1961. RTGs on Mars and Deep Space Missions: RTGs power Mars landers and rovers (Viking, Curiosity, Perseverance), and deep space missions like Voyager, Galileo, and Cassini, providing long-term power in harsh environments. Fission Reactors vs. RTGs: RTGs suit small systems and backup power, while fission reactors are better for high-power needs of human expeditions. Plutonium-238 Production Challenges: The scarcity of plutonium-238 is due to its production requiring nuclear reactors and past moratoriums on reprocessing. Americium-241 as an Alternative: Americium-241, abundant in spent fuel and now accessible due to lifted moratoriums on reprocessing, is a viable alternative for powering missions despite lower energy density. Americium in Smoke Detectors and Safety: Americium's safe use in smoke detectors is highlighted, while acknowledging the hazards of working with nuclear materials. Public Perception and RTG Safety: Discussion covers historical atomic energy perceptions, from early toys to environmental concerns, emphasizing rigorous engineering and safety measures like ablative and impact-resistant casings for RTGs.
