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.

Astronomy Cast Ep. 768: Comets' Unpredictability By Fraser Cain & Dr. Pamela Gay Streamed live on Oct 13, 2025. So it's been decades since we've seen a bright comet in the sky. And actually there was a pair — Hale-Bopp and Hyakutake. And then, silence! And unmet promises by the Universe to give us a bright comet. Comets are unpredictable, and they arrive precisely when they intend to. Is it time again for a bright comet? If you asked us in January if 2025 was going to have any outstanding comets would fly through the Solar System, we would have (and we did) say "no." And we were wrong. Comets are fickle, unpredictable, and like to do exactly what we didn't predict.   This show is supported through people like you on     In this episode, we'd like to thank: Andrew Poelstra, BogieNet, Brian Cagle, Burry Gowen, David, David Rossetter, David Truog, Ed, Gerhard Schwarzer, Jason Kwong, Jeanette Wink, Michael Purcell, Olger, Sergio Sancevero, Sergey Manouilov, Siggi Kemmler, Stephen Veit

"My interest is beyond that. Beyond the solar system. Of course I have this interest in Mars, but what I'm really interested in is the post planetary condition of humankind.” Angelo Vermeulen   Angelo Vermeulen and I talk about imagination, exploration, and what it means to lead and collaborate beyond boundaries. Angelo is  a scientist and a visual artist, who loves to build crossovers between those two worlds. He shares how exploring deeply across disciplines — from biology to philosophy to design — shapes the way we understand creativity, leadership and the future of humanity. His work invites us to think not just about life on Earth, but what life beyond the solar system might look like. We talk about creativity as a universal skill, leadership in extreme environments, finding courage to express our ideas and why co-creation demands vulnerability and trust. Angelo shares stories from his time leading a Mars simulation in Hawaii, collaborating with ESA on space systems design and exploring the evolution of our species, including IVF in space.    Angelo Vermeulen is a space biologist, complex systems engineer, and artist who integrates science, design, and ecology to explore the future of human life in extreme environments. At TU Delft, he develops bio-inspired systems for space settlement, including self-replicating architecture and bioregenerative life support. As CTO of SpaceBorn United, he leads the development of the world's first IVF incubator designed for space, advancing research on human reproduction beyond Earth. He co-founded SEADS, a transdisciplinary collective whose work has been exhibited across continents and flown to the International Space Station. In 2013, he commanded the first NASA-funded HI-SEAS Mars simulation, and in 2022, he reached the top 6% in the ESA astronaut selection process. With over 60 publications and multiple fellowships—including from TED and Parsons—Angelo's work bridges art and science to challenge how we inhabit our shared future in space and on Earth.   Connect with Angelo: Through his website: https://www.angelovermeulen.net On LinkedIn: https://www.linkedin.com/in/angelovermeulen   References: Sir Ken Robinson's TED Talk “Do Schools Kill Creativity?"

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.

If the United States is indeed in a space race with China, why are we abandoning space science programs across the Solar System? This question, posed by guest Maxwell Zhu in a recent op-ed co-authored by The Planetary Society's chief of space policy, reveals the current myopia around human spaceflight and the missing focus on a growing and ambitious new entrant into space science in the 21st century.

The new release, DP-6 - Winds of Saturn, is dedicated to one of the windiest places in the Solar System and delves into the murky depths of Saturn's atmosphere. From time to time, powerful "white" storms, each larger than Earth, break through the cloud layers. Incredibly strong winds create unusual cloud structures. There are three areas where special clouds, known as "Cloud Decks," can be found. Three versions of the track on the release are dedicated to these areas: Top Visible Cloud Deck, Second Cloud Deck, and Lowest Cloud Deck. ▶ Buy: https://dp-6.bandcamp.com/album/winds-of-saturn https://www.beatport.com/release/winds-of-saturn/5404815 ★ You can support DP-6 and get early access to new works:

Mysterious Object Cruising Through Solar System May Have Emitted a Signal, Scientist Says In 1977, the Ohio State University's Big Ear radio telescope received an unusually strong narrowband radio signal, leading to widespread excitement about the possibility of having encountered evidence of life beyond Earth. At the time, astronomer Jerry Ehman spotted the highly unusual outburst in printed out records, annotating the major radio band fluctuation with the word “Wow!” in red pen, thereby giving it a memorable nickname: the “Wow! Signal.” Now, Harvard astronomer and alien hunter Avi Loeb has a wild new theory about the signal. In a new blog post, he suggested that interstellar object 3I/ATLAS, which is currently cruising through our solar system, could've sent off the signal back in 1977 — when it was still 600 times the distance between the Earth and Sun away from us.

(00:00:00) Mercury's Shrinking Secrets: Insights into the Solar System's Smallest Planet (00:00:43) Mercury's Ongoing Shrinkage (00:03:11) NASA's Carruthers Geocorona Observatory (00:11:52) Insights from Martian Meteorite NWA 16254 (00:14:23) Tech News In this episode of SpaceTime, we explore the intriguing dynamics of Mercury's shrinking size, embark on a mission to unveil Earth's elusive exosphere, and uncover the secrets of ancient volcanic activity on Mars.Mercury's Ongoing ShrinkageRecent research published in AGU Advances reveals that Mercury continues to shrink as it cools, a process that has been ongoing since its formation 4.6 billion years ago. 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

In his first interview since his unmasking on September 20, JP shared information from his latest contact with a Nordic extraterrestrial who met him near his Florida home. The Nordic explained that Martian colonists who escaped the Red Planet after catastrophic changes millennia ago have just returned to our solar system. This was the same Nordic who met JP on February 11, 2025 (Update 43), to help him remember a 2018 contact incident where he was taken on a spacecraft and shown records of the collapse of the Martian civilization and the emigration of Mars refugees to Earth in space arks and other large spacecraft. There is also a connection between the returning Martians to 3I/Atlas, which will make its closest approach to Mars next week on October 3. According to what JP was told, 3I/Atlas may change course to directly interact with or even land on Mars.JP was told that the Martians who fled to Earth after their planet's destruction settled on both the surface and under the oceans. It is unclear whether the returning Martians plan to reestablish a presence on Mars or join their compatriots in underwater colonies on Earth. According to the Nordic, the returning Martians do not represent any kind of threat to humanity. This leads to the conclusion that the return of former Martians presents an opportunity for humanity to gain a deeper understanding of the true history of our solar system and the origins of our species.The February 8 Update by JP is available here: https://exopolitics.org/jp-taken-to-witness-ancient-mars-evacuation-jp-update-43/More Updates by JP are available here: https://exopolitics.org/jp-articles-photos-videos/Join Dr. Salla on Patreon for Early Releases, Webinar Perks and More.Visit https://Patreon.com/MichaelSalla/

https://www.youtube.com/watch?v=yH4uczqmhQ0 From Jan 20, 2023. 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. And now we know a lot more about its planet, LHS 475 b.   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!

In 1977, NASA took advantage of a once-in-a-lifetime alignment of the planets to send two probes to the outermost reaches of the solar system.  They sent back the best images and data yet available about Jupiter, Saturn, Uranus, and Neptune.  The program was a smashing success. However, the probes didn't stop traveling. They kept going and going, all the while maintaining contact with Earth. They ended up teaching us far more about the Solar System than we ever expected.

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: 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

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: 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

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.

For decades, Uranus has puzzled scientists. Unlike the other giant planets, Voyager 2’s 1986 flyby suggested the ice giant emitted no excess heat. Now, thanks to new analyses of Voyager data, decades of ground-based and space-based observations, and refined models, scientists have confirmed that Uranus does radiate more heat than it receives from the Sun. Host Sarah Al-Ahmed speaks with atmospheric scientist Michael Roman (Assistant Professor at the Universidad Adolfo Ibáñez in Chile) about his team’s new study showing Uranus emits around 12.5% more energy than it absorbs. Together, they explore what this means for our understanding of Uranus’s atmosphere, its bizarre seasonal cycles, the planet’s violent past, and why these findings strengthen the case for a future flagship mission to the Solar System’s overlooked ice giants.Stick around for What’s Up with Bruce Betts, Planetary Society chief scientist, for a look at Uranus’ newly discovered moon and a new random space fact.
