In this powerful and timely episode, we explore the deeper spiritual meaning behind the arrival of Comet 3I ATLAS — the third known interstellar visitor to enter our Solar System.While mainstream media may be stirring stories of fear, uncertainty, or even alien contact, we tune into a higher truth: this celestial being is not something to fear — it is a messenger of consciousness. A cosmic traveler carrying ancient wisdom and divine intelligence from beyond the stars. 3I ATLAS is a consciousness in its own right — a mirror and a catalyst for humanity's collective awakening. As it draws nearest to Earth on December 21, it carries frequencies of activation — awakening dormant layers of our ancient DNA and re-aligning us with our soul's higher purpose. Many of us have been feeling the energetic “final push” to purge and release — shedding patterns, beliefs, careers, homes, and relationships that no longer align with who we are becoming. This comet invites us to embrace stillness, welcome the darkness, and trust the transformation that unfolds within it.As we move through this profound gateway, our intuitive gifts and inner light begin to strengthen. The darkness is not our enemy — it's the fertile void where our true power takes root.Join us for an illuminating conversation that blends cosmic insight, grounded wisdom, and energetic preparation for what's to come.In this episode we discuss:The spiritual message and consciousness of Comet 3I ATLASHow mainstream narratives can distort cosmic truth through fearThe energetic purpose of this interstellar arrivalCollective and personal purging before activationHow to align with the comet's frequencies through stillness and surrenderPreparing for the December 21 activation and the rise of ancient light withinKey takeaway:You are not being asked to do more — you are being asked to be still, to listen, and to remember who you are. The stars are speaking — and this time, they are speaking through the light of an ancient traveler.

00:45 A coronal mass ejection from a distant starResearchers have detected what they say is the strongest evidence yet of a coronal mass ejection (CME) coming from a star other than our Sun. CMEs are massive bursts of fast-moving plasma that can be detected thanks to the characteristic radio signal they produce. However, despite decades of searching, these signals have only been identified from the Sun. Now a team has identified a similar signal coming from a distant star in the Milky Way. They hope their discovery will lead to better understanding of the impact these colossal events might have on the atmospheres of exoplanets, and their chances of being habitable.Research Article: Callingham et al.12:28 Research HighlightsVideo footage of a devastating earthquake provides a first-of-its-kind glimpse of a dramatic ground rupture — plus, a flock of comets seen outside our Solar System.Research Highlight: Single video camera tells the story of deadly Myanmar quakeResearch Highlight: A host of ‘exocomets' swarms a distant star14:29 The rare genetic variants that may increase the risk of ADHDAttention-deficit/Hyperactivity disorder (ADHD) is a condition that affects around 1 in 20 young people, but its underlying causes are not fully understood.

How do planets start? Host Simon Steel (SETI Institute) speaks with Melissa McClure (Leiden University), lead author of a new study that caught the earliest spark of planet formation. Using JWST and ALMA, the team detected silicon monoxide (SiO)—both gaseous and likely crystalline—and pinpointed where hot, rock-forming minerals are condensing inside the protoplanetary disk of HOPS-315, ~1300 light-years away in Orion. They also map the action to a belt-like region similar to our Solar System's asteroid belt. What does SiO reveal about shocks, heat, and the first solids that seed planets? Join us to unpack the chemistry, the physics, and the cosmic "baby book" of a solar system in the making.

Asteroid Belt and Meteorite Origins (Solar System Formation 2.  Greg Brennecka discusses the origins of objects falling to Earth, explaining that the asteroid belt's location is determined by the movement of large planets like Jupiter and Saturn, whose gravitational interactions swept material into specific resonance zones. Cosmochemists can link meteorites back to parent bodies such as Vesta by matching spectral data from probes to laboratory samples, and pieces of Mars also land on Earth, kicked off by space impacts and definitively identified by matching trapped gases to the known Martian atmosphere. Brennecka notes that the massive impact that formed the Moon likely caused the entire Earth to flash-melt, suggesting that if life existed before that event, it would have been extinguished by the heat. 1958

Universe's Expansion May Be Slowing: New research challenges the long-held belief that the universe's expansion is accelerating due to dark energy. This study suggests that dark energy might be evolving and weakening over time, potentially leading to a scenario where gravity could eventually dominate, resulting in a Big Crunch.Tianwen 1's Interstellar Photography: China's Tianwen 1 orbiter has captured stunning images of the interstellar object 3I Atlas, marking a significant achievement in its extended mission phase. These observations provide crucial insights into the object's composition and offer practice for future sample return missions.Launch Scrub Update: The much-anticipated launch of United Launch Alliance's Atlas V rocket carrying the Viasat 3F2 satellite was scrubbed due to ground systems equipment issues. The launch has been rescheduled, with hopes for a successful liftoff soon, as this satellite is crucial for global broadband coverage.Mysterious Black Hole Flare: A supermassive black hole has emitted an unprecedentedly long-lasting flare, observed by the Zwicky Transient Facility. This unusual event raises questions as it defies typical flare durations, hinting at the consumption of an exceptionally massive star.Alien Probes in Our Solar System? A recent scientific paper explores the concept of von Neumann probes—self-replicating robotic explorers that could potentially be in our solar system. The authors suggest searching for technosignatures on the Moon, where artifacts could remain undisturbed for millions of years.For more cosmic updates, visit our website at astronomydaily.io.

El visitante vuelve: El cometa interestelar 3I/ATLAS reaparece con datos nuevos y un cambio de velocidad que intriga a la NASA.  Por Félix Riaño @LocutorCo  Escucha todos los días el Flash DiarioDespués de pasar oculto tras el Sol durante octubre, el visitante interestelar 3I/ATLAS volvió a escena con novedades que están desconcertando a la comunidad científica. NASA ha confirmado que el objeto cambió su velocidad y trayectoria de forma que no encaja con las fuerzas conocidas. Al mismo tiempo, su color se tornó azul brillante y su brillo aumentó más de lo esperado. En este episodio vamos a repasar qué se ha descubierto desde su paso por el perihelio, qué está analizando la NASA y cuándo podremos volver a observarlo desde la Tierra.  El 29 de octubre, el cometa 3I/ATLAS alcanzó su punto más cercano al Sol. Los observatorios que siguieron su paso registraron un aumento repentino de luminosidad y un cambio de color: de verde a azul. Pocos días después, NASA confirmó algo más extraño aún: una aceleración no gravitacional, un impulso que lo movió fuera de su ruta calculada.Los científicos del Laboratorio de Propulsión a Chorro publicaron que el objeto avanza ahora a unos 245 000 kilómetros por hora, un incremento difícil de justificar solo con la acción del calor solar. Harvard, la Agencia Espacial Europea y el Instituto Coreano de Astronomía están revisando la información más reciente mientras el cometa vuelve a hacerse visible antes de continuar su viaje fuera del sistema solar.  Volvió… y ahora se comporta de forma imposible.  Las nuevas observaciones provienen de telescopios en Chile, Sudáfrica, Australia y del James Webb Space Telescope, que captó un halo azul a su alrededor. El análisis espectral indica una proporción inusual de dióxido de carbono ocho veces superior al agua, y presencia de níquel metálico en niveles que no existen en cometas del sistema solar.La luz de 3I/ATLAS muestra además una polarización negativa extrema, un patrón de vibración que no se había visto antes. Para el astrónomo coreano Moon Hong-kyu, esto sugiere que el cometa se formó en una región de temperatura extremadamente baja, muy diferente de cualquier entorno cercano al Sol.Las observaciones también confirman que su núcleo mide unos once kilómetros y que la masa ronda los 33 000 millones de toneladas, lo que lo convierte en el objeto interestelar más grande jamás detectado.  El comportamiento de 3I/ATLAS ha abierto un debate científico y político. La congresista estadounidense Anna Paulina Luna pidió a la NASA publicar las imágenes tomadas por la cámara HiRISE del orbitador de Marte y por el rover Perseverance, captadas cuando el cometa pasó a unos 30 millones de kilómetros del planeta rojo.Al mismo tiempo, Avi Loeb, físico de Harvard, enumeró diez anomalías en su trayectoria, entre ellas la aceleración no explicada, la luz polarizada, el cambio de color y una coincidencia angular con la dirección del famoso “Wow! Signal” de 1977. Según sus cálculos, la probabilidad de que todos estos fenómenos ocurran por azar es del 0,005 %.Mientras tanto, en internet proliferan teorías sin evidencia que lo describen como una nave o una esfera de materia oscura, pero la NASA insiste en que no hay señales de tecnología ni amenaza para la Tierra.  Lo comprobable es fascinante por sí mismo. La NASA detectó un aumento de velocidad justo después del perihelio, seguido de una ligera desviación en la órbita. El fenómeno podría deberse a chorros de gas que actuaron como un “empuje natural”, aunque no se ha observado la cantidad necesaria de material expulsado.El James Webb realizará en diciembre una nueva campaña de observación para buscar una nube de gas y polvo que confirme o descarte esa hipótesis. Si no la encuentra, los astrónomos tendrán que revisar las explicaciones actuales sobre la dinámica de los objetos interestelares.Por ahora, lo único seguro es que 3I/ATLAS sigue acelerando y alejándose, y que el 19 de diciembre estará en su punto más cercano a la Tierra: unos 270 millones de kilómetros.  El cometa se podrá observar desde el hemisferio norte en las madrugadas de diciembre con telescopios de al menos 30 centímetros de apertura. Los mejores momentos para buscarlo serán antes del amanecer, hacia el horizonte este.La Agencia Espacial Europea, a través de su misión JUICE, también tiene programadas observaciones entre el 2 y el 25 de noviembre desde la órbita de Júpiter. Se espera que esas imágenes, junto con las de NASA y KASI, permitan comparar la composición de 3I/ATLAS con los cometas Borisov y ʻOumuamua, los otros dos visitantes interestelares confirmados.Mientras tanto, los equipos científicos coreanos destacan que su alto contenido de níquel y la escasez de agua apuntan a un origen en una zona fría del disco grueso de la galaxia, quizá un remanente de material primitivo expulsado hace millones de años desde un sistema estelar extinguido.  3I/ATLAS sigue sorprendiendo a los astrónomos con cada nueva observación. Su cambio de velocidad y su color azul brillante plantean preguntas abiertas sobre cómo se comportan los objetos interestelares. El 19 de diciembre será su punto más cercano a la Tierra. Puedes seguir su recorrido en tiempo real en “Eyes on the Solar System” y en Flash Diario.  El cometa 3I/ATLAS reapareció con color azul y velocidad inexplicable. NASA lo estudia antes de su paso cercano en diciembre.

Here are three notable statements by Avi Loeb regarding the interstellar object 3I/ATLAS (also known as C/2023 A3). 1. It could be technological or engineeredLoeb proposes that 3I/ATLAS might not be a simple natural object, but one with artificial or engineered features. Example quotes:He writes that “this object could be technological, and possibly hostile as would be expected from the ‘Dark Forest' resolution to the Fermi Paradox.” He suggests that if it “generates its own light, then it could be much smaller than expected …” Loeb also suggests the trajectory may be “fine-tuned” or “optimized” for a visit through our Solar System rather than a random interstellar path. His position is one of possibility, not firm conclusion; he often emphasizes that the scenario is unlikely but worth considering because of its implications.2. It shows several “anomalies” compared to known comets or interstellar objectsLoeb has pointed out multiple features that he claims cannot be easily explained under typical comet/asteroid models. Some specific anomalies he highlights:Its trajectory is close to the ecliptic plane (i.e., aligns within ~5° of the planetary orbital plane) — this, he argues, makes a random entry statistically unlikely. It produced a “sunward jet” or anti-tail (i.e., an emission or structure pointing toward the Sun) which he says is atypical for known comets. It exhibits an “extreme negative polarization” signature (a polarization measurement of –2.77 % at a particular phase angle) which he says is significantly different from all known comets. He also notes compositional oddities: in his blog he mentions, for example, a large nickel:iron ratio and small water fraction in the outgassed material. In short: Loeb treats 3I/ATLAS as anomalous, and argues that such anomalies elevate interest in the artificial-origin hypothesis.3. While it may be artificial, we mustn't ignore the natural hypothesisEven though Loeb emphasizes the possibility of an artificial origin, he is careful to maintain that the most probable outcome still remains that 3I/ATLAS is a natural object. For example:In a blog post, he wrote: “As of now, 3I/ATLAS appears most likely to be a natural comet. But the remote possibility … must be considered seriously as a black-swan event with a small probability, because of its huge implications for humanity.” Similarly, in press coverage he is quoted: “By far, the most likely outcome will be that 3I/ATLAS is a completely natural interstellar object, probably a comet.” He therefore positions his artificial-origin hypothesis as speculative, but worth preparing for — especially given the stakes if such a hypothesis turned out to be true.30 Day Free Trial Of 4biddenknowledge.TV 30 Day Free Trial On 4biddenknowledge.TVSupport the show

The big brokerage firms are fighting for your investment accounts Our investment advisory firm over the years has never been a favorite of the big brokerage firms because we generally only do three, maybe four trades on average per year. But the big brokerage firms are now acting like the casinos in Las Vegas and are doing everything they can to get you on their platform. They will give you all kinds of tools and seminars, so you'll take higher risk and do more trading. In the meantime, they're downplaying the risk of trading. You see also like the casinos in Las Vegas, there are now stories of them giving away free rooms for the big players and they are giving you free software and free education on how to trade. Robinhood even invited 1000 people to Las Vegas and took them go kart racing and provided classes with their new trade platform. Schwab and Fidelity are doing similar types of events to get you to use more of their services. Once they get you in the door, they can show you how to use margin debt, which by the way hit a new record of $1.13 trillion in September, along with option trading and other exciting ways to make you think you can make a lot of money. Doesn't that sound like the casinos in Las Vegas that try and get you to hit the gambling tables? Unfortunately, it seems to be working somewhat because the percentage of investors who now have self-directed accounts is 33%, which is a big increase from 24% just five years ago. My problem with this, as you can tell, is I don't believe they're teaching people how to invest but more on how to gamble and how exciting it can be. Going back 100 years it's still the same with Wall Street, they will make some big profits, and the small investors will lose most if not all of their nest egg. Can Travis Kelce turn around Six Flags? If you're not sure who Travis Kelce is, he is a tight end for the Kansas City Chiefs and engaged to the well-known singer Taylor Swift. Six Flags, which is a public company that trades under the symbol FUN, has received an investment of $200 million from the activist investment company JANA Partners. It was not disclosed how much investment Travis has of the $200 million, but he does like to invest in companies both public and private. He has investments in over 30 companies that include manufacturing, distribution, consumer goods, entertainment, and a beer company. He is pretty excited about his investment because as a kid he used to love the roller coasters, Dippin' Dots and him and his brother have great memories at Six Flags. He has suggested that they do a roller coaster with a 300 foot drop where riders feet dangle from beneath. Investing in Six Flags seems to be an uphill battle. Year to date the stock is down roughly 45%, the company is losing money and has a market capitalization of $2.6 billion. Travis does have a long-term perspective on all his investments likes we do. He is OK investing in a company losing money in hopes it could be turned around. Our philosophy at our firm is we will not invest in companies that do not have earnings. One benefit he does have is obviously his name and I'm sure if him and his fiancé, Taylor Swift, would start showing up at Six Flags, you can bet that they will be all over the news giving the company some nice free advertising.   Markets actually declined after the Fed rate cut  On Wednesday, the Fed announced they would lower their benchmark overnight borrowing rate by 0.25% to a range of 3.75%-4%. This marked the second consecutive cut of 0.25% and there is still one meeting left this year where we could see another rate cut. The keyword here is could and the lack of conviction around another cut is likely what spooked the market. Powell said a December rate cut isn't a “foregone conclusion” and while recently appointed Fed Governor Stephen Miran again dissented in favor of a 0.5% cut, there was also a hawkish dissent with Kansas City Fed President Jeffrey Schmid voting for no decrease. Schmid's vote and Powell's language was likely what sent the market lower after the announcement as many essentially had the December rate cut factored in as a sure thing. Powell also added that there is “a growing chorus” among the 19 Fed officials to “at least wait a cycle” before cutting again. This resulted in traders lowering the odds for a December cut to 67% from 90% the day prior. Given the lack of data and an economy that still appears to be in an alright position, I do believe the Fed needs to be careful cutting too quickly especially since they are taking another accommodative stance with the announcement that they would be ending the reduction of its asset purchases – a process known as quantitative tightening – on Dec 1. This in theory will stimulate the Treasury and mortgage-backed securities markets, which should help with longer dated debt instruments, as the Fed was allowing these assets to just roll off the balance sheet and now will need to step in and buy new debt to replace the securities as they mature. While QT shaved off around $2.3 trillion from the Fed's balance sheet, Covid led to a major expansion from just over $4 trillion to close to $9 trillion. The question is with the rapid expansion just a few years ago, was enough removed from the balance sheet to put it at a more normalized level. Like with the Fed cuts, I do believe if monetary policy eases too much, we risk a return of inflation and a further increase in many speculative assets that could cause problems down the road.   Financial Planning: When does a Solar System Make Sense? Buying a solar system generally makes the most sense if you use a lot of electricity and plan to stay in your home long term. Installing by the end of 2025 allows you to capture the 30% federal tax credit, which significantly shortens the payback period. If the system is financed with a mortgage or home equity line of credit (HELOC), the interest may be tax-deductible, allowing for little or no upfront cash outlay and after-tax loan payments that can be lower than the monthly electricity savings. Owned solar panels usually increase home value, though not always enough to fully offset the system's cost, which is why longer-term ownership is important to recoup the investment. In California, including a battery is almost always recommended so you can store power generated during the day for use at night, reducing the need to buy expensive electricity from the grid. Leasing can be attractive for shorter-term homeowners if lease payments are well below current utility costs, but leases generally don't increase home value and don't qualify for tax credits. The main advantage is immediate monthly savings without an upfront investment, though leased panels can complicate a future home sale. In some cases, it may be best not to install solar at all—for example, if you don't plan to stay in the home long term, or if your electricity usage and potential savings are too low to justify the hassle and possible roof wear from installation.   Companies Discussed: The Coca-Cola Company (KO), Capital One Financial Corporation (COF), QUALCOMM Incorporated (QCOM), Knight-Swift Transportation Holdings Inc.

00:48 The stereotypes hidden in Internet imagesStereotyped assumptions about women's ages and their perceived job suitability are enhanced by Internet imagery, according to new research. A study of hundreds of thousands of online images shows that women appear younger than men. This stereotype extends to the jobs that people perceive women do, with men being associated with roles such as CEO or head of research, while women were linked to occupations like cook or nurse. The research shows that these biases have been embedded into the training data for AI models and could affect future hiring. The researchers caution that society is at risk of creating a ‘self-fulfilling prophecy' where these stereotypes shape the real world.Research Article: Guilbeault et al.News and Views: Distorted representations of age and gender are reflected in AI models13:24 Research HighlightsA very hungry planet — plus, how climate change is leading to larger trees in the Amazon.Research Highlight: ‘Rogue' planet is fastest-growing ever observedResearch Highlight: Trees of the Amazon are becoming even mightier15:49 Astronomers name their favourite exoplanetThirty years ago, astronomers announced the discovery of the first exoplanet around a Sun-like star, sparking a renewed passion into spotting these planets that lie beyond our Solar System.

Scientists have estimated that the planet's radius has contracted by between 2.7 to 5.6 kilometres due to cooling-induced faulting. This study employs new methods to provide a more accurate understanding of Mercury's long-term thermal history, which could also be applied to other planetary bodies, including Mars.NASA's Carruthers Geocorona ObservatoryNASA has launched the Carruthers Geocorona Observatory to study Earth's invisible halo, the exosphere. This mission aims to capture the first continuous observations of the Geocorona, revealing the dynamics of hydrogen atoms escaping into space. Understanding the exosphere's response to solar activity is crucial for predicting space weather events that could affect astronauts on missions to the Moon and beyond. The observatory will provide insights into how Earth retains water and may even aid in the search for exoplanets with similar atmospheric conditions.Insights from Martian Meteorite NWA 16254A meteorite discovered in the Zaharov Desert is shedding light on Mars's ancient volcanic systems. The rock, classified as NWA 16254, offers unprecedented insights into the planet's magmatic processes, indicating a two-stage crystallisation process that occurred under varying pressure conditions. This discovery could help scientists understand Mars's thermal history and its volcanic evolution over billions of years, raising questions about the planet's past and its potential for hosting life.www.spacetimewithstuartgary.com✍️ Episode ReferencesAGU Advanceshttps://agu.onlinelibrary.wiley.com/journal/23337380NASA Geocorona Observatoryhttps://www.nasa.gov/Planetary Science Journalhttps://iopscience.iop.org/journal/2632-3338Become a supporter of this podcast: https://www.spreaker.com/podcast/spacetime-space-astronomy--2458531/support.Mercury's Ongoing ShrinkageNASA's Carruthers Geocorona ObservatoryInsights from Martian Meteorite NWA 16254

The James Webb Space Telescope took time away from finding the earliest galaxies or imaging incredible nebulae to test out its planet hunting capabilities. To say it was immediately successful would be an understatement. JWST is showing us that it can do almost anything in astronomy and cosmology.   Its latest trick is picking out an exoplanet candidate, confirming it exists and telling us about this alien world. LHS 475 is a red dwarf star 41 light-years away from our Solar System in the southern hemisphere constellation of Octans.

Preview: This file contains a conversation between John Batchelor and Bob Zimmerman about 3i Atlas, the third interstellar object discovered. Bob Zimmerman explains that 3i Atlas is a comet originating from another solar system, currently moving quickly through our solar system and expected to leave soon. Telescopes worldwide are observing it, including the Gemini South telescope in Chile, which captured new images showing its tail is growing. Despite its interstellar origin, Bob Zimmerman reports that its characteristics are largely comparable to other comets known to us, though some components like its carbon dioxide coma and water nucleus are somewhat unique. He has posted more information about this comet on "Behind the Black". 1958

The Asteroid Hunter: A Scientist's Journey to the Dawn of our Solar System Hardcover – March 19, 2024 by  Dante Lauretta  (Author) Title: Bennu's Unexpected Challenges Author: Dante Lauretta After a successful launch in summer 2016, the OSIRIS-REx spacecraft approached its target, Bennu. Pre-arrival telescopic data from the Arecibo planetary radar system and the Spitzer Space Telescope suggested Bennu's surface would be "beach-like" with particles smaller than an inch. However, upon arrival, the team discovered a rough, rugged, and boulder-strewn surface, like a "great big gravel pile," making it difficult to find a safe, flat landing site with small particles. Bennu also exhibited unexpected "popcorn" activity, continuously ejecting particles due to its microgravity. Despite carefully selecting the Nightingale landing site, the Touch-And-Go Sample Acquisition Mechanism (TAGSAM) unexpectedly plunged into the fluid-like surface, overfilling and causing the collected sample to leak. 1954

 Dante LaurettaThe Asteroid Hunter: A Scientist's Journey to the Dawn of our Solar System Hardcover – March 19, 2024 by  Dante Lauretta  (Author) Title: Triumph and Legacy: The Sample's Return Author: The OSIRIS-REx spacecraft, despite the leaking sample, proved robust and began its journey back to Earth. During re-entry over the Utah Test and Training Range, a critical scare occurred: the drogue chute, meant to stabilize the capsule at 100,000 feet, failed to deploy on time. Dante Lauretta, recalling the Genesis mission's parachute failure, endured three desperate minutes until the main chute deployed at 60,000 feet, signaling mission success. The sample was successfully recovered. OSIRIS-REx was then rebranded OSIRIS-APEX, handed over to Dante's former student and now assistant professor, Danny Dea Justina. The mission continues to explore another near-Earth asteroid, Apophis, carrying forward Mike Drake's vision of training future leaders in planetary science. 1958

The Asteroid Hunter: A Scientist's Journey to the Dawn of our Solar System Hardcover – March 19, 2024 by  Dante Lauretta  (Author) Title: Genesis of a Galactic Pursuit Author: Dante Lauretta Title: OSIRIS-REx: Defining the Mission Author: Dante Lauretta Following two rejections, Dante Lauretta was tasked by Mike Drake to define the scientific objectives for a new asteroid sample return mission. Lauretta developed the acronym OSIRIS-REx, standing for Origins (astrobiology), Spectral Interpretation (astronomers' surveys), Resource Identification (resource utilization), Security (planetary defense), and Regolith Explorer. This name reflects diverse interests, from the seeds of life on Earth to asteroid impact hazard mitigation. The mission, now with a larger budget under the New Frontiers program, was selected by NASA on May 25, 2011. During this time, a gravely ill Mike Drake designated Dante as the mission's "risk mitigation," entrusting him with its leadership. 1954

The Asteroid Hunter: A Scientist's Journey to the Dawn of our Solar System Hardcover – March 19, 2024 by  Dante Lauretta  (Author) Title: Genesis of a Galactic Pursuit Author: Dante Lauretta In February 2004, Assistant Professor Dante Lauretta was recruited by his mentor, Mike Drake, to join Steve Pricefrom Lockheed Martin in pursuing an asteroid sample return mission for NASA. Drake, the director of the University of Arizona's Lunar and Planetary Laboratory (LPL), aimed to bring the university back to the forefront of space exploration. Inspired by a "Work for NASA" ad in the student newspaper in 1992, Lauretta, a cosmochemist, began a journey marked by initial rejections. Their first proposal in July 2004 received the lowest possible ranking, a "gut punch," which made them redouble their efforts. 1953

Earlier this summer, astronomers discovered something strange whizzing past Jupiter: an interstellar object. Scientists named it 3I/ATLAS. It's only the third interstellar object ever observed, and it's due to leave the solar system by the end of the year, so the race is on to learn as much as we can about it. Host Flora Lichtman talks with astrochemist Stefanie Milam about what this object could teach us about other solar systems—and ours.And, for the past two years, researchers have been studying samples from the near-Earth asteroid Bennu, trying to tease out details about its origins, and what they tell us about our solar system. Researcher Jessica Barnes describes a new analysis of Bennu samples that found stardust, the residue of ancient exploding stars, older than our solar system.Guests: Dr. Stefanie Milam is an astrochemist at NASA and a project scientist for the James Webb Space Telescope. Dr. Jessica Barnes is an associate professor in the Lunar and Planetary Laboratory at the University of Arizona.Transcripts for each episode are available within 1-3 days at sciencefriday.com.Subscribe to this podcast.
