David Friedberg: “This will be one of the most amazing discoveries of our lifetime” “Friedberg, what's your Breakthrough of the Year?” “Okay, we haven't talked about it on the show, this definitely deserves a science corner, but asteroid Bennu.” “NASA sent a probe. They pulled a bunch of samples up in 2020. They landed back on Earth in 2023.” “Two days ago, they showed that on asteroid Bennu, there are nucleic acids, there are amino acids, there are sugars.” “All of the building blocks of life were found on this asteroid floating through space.” “This is going to end up being one of the most amazing discoveries of our lifetime because it really does show that life is not necessarily unique to planet Earth.” “This was an asteroid that's been floating around for 4.5 billion years, and it's got all the components of life on it.” “It's a pretty incredible discovery.” ------------------------------------ Thanks to our partners for making this happen!

NEW: NASA has increased the chance a major asteroid smashes into Earth in 2032, now giving it a 3.1% chance, up from 2.6% last week. NASA says the odds the asteroid hits Earth is 1 in 32. It is big enough to wipe out an entire city. The large cities with the highest risk are Bogotá, Abidjan, Lagos, Khartoum, Mumbai, Kolkata and Dhaka. According to experts, the 177-foot diameter asteroid would release 8 megatons of energy on impact, 500 times the energy released by the atomic bomb that destroyed Hiroshima. NASA has successfully tested asteroid deflection technologies. China will also be testing its own technology on a small asteroid in 2027. "This is not a crisis at this point in time. This is not the dinosaur killer. This is not the planet killer. This is at most dangerous for a city," said the head of the European Space Agency's planetary defense office, Richard Moissl.

400 kilometers above Earth, a butterfly emerged from its pupa in orbit—a breakthrough by Chinese researchers showing that life can persist, and even take flight, in microgravity. The achievement marks a notable advance in space life science under extreme conditions. The butterfly developed inside a small, sealed space system designed by a team from Chongqing University and launched into orbit in December 2025. Images from space showed it resting on leaves, fluttering its wings, and moving freely inside the capsule, while monitoring data confirmed that the miniature environment remained stable despite the challenges posed by microgravity. Behind the moment lay years of technical work. By overcoming key scientific hurdles and building a lightweight, self-sustaining ecosystem, the research team demonstrated that complex life processes can be supported in orbit. The “space butterfly” offers new insight into the resilience of Earth life and provides a basis for future missions aimed at sustaining life during long journeys beyond the planet.

Do you know what an exoplanet is? 2019 physics laureates Michel Mayor and Didier Queloz have explored our home galaxy, the Milky Way, looking for unknown worlds. In 1995, they made the very first discovery of a planet outside our solar system, an exoplanet, orbiting a solar-type star called 51 Pegasi. They reported their discovery in a Nature article, published in November 1995. This discovery started a revolution in astronomy and over 4,000 exoplanets have since been found in the Milky Way. See the original article: Video animation: Animation of a exoplanet. The exoplanet HD 189733b lies so near its star that it completes an orbit every 2.2 days. In late 2011, NASA's Hubble Space Telescope found that the planet's upper atmosphere was streaming away at speeds exceeding 300,000 mph. Just before the Hubble observation, NASA's Swift detected the star blasting out a strong X-ray flare, one powerful enough to blow away part of the planet's atmosphere.

So did Neil deGrasse Tyson’s mentor, Carl Sagan prefer non-government exploration and colonization of space? A robust and emphatic, yes. But Neil has somehow concluded a private company funding to space is of no financial value and should be done through government programs that has kept humans grounded since Apollo. Neil has done significant damage to himself and popularization of science in general and I am more than disappointed. So I am speaking up. Here are the receipts: Sailing The Seas Of The Cosmic Oceans The Planetary Society’s Solar Sail Launch was a private funded space launch. I know Nevis not only did I donate to make this happen a number of us met with the team to think out the process. Carl Sagan, the renowned astrophysicist, cosmologist, and science communicator, made significant waves in the scientific and space exploration communities when he announced his intention to pursue the development of solar sail technology using private funds in collaboration with Russian spaceflight capabilities. Solar sails, which harness the momentum of photons from sunlight to propel spacecraft, had long been a topic of interest for Sagan, who recognized their potential for enabling long-term, low-cost exploration of the solar system and beyond. The concept of solar sailing dates back to the early 20th century, but it gained public attention during the 1970s and 1980s, thanks in part to Sagan’s advocacy. He often discussed the promise of solar sails in making space exploration more sustainable and accessible. His vision for a solar sail program crystallized in the 1990s, during a period of renewed interest in private-public partnerships and international collaboration in space exploration. Sagan’s announcement marked a major turning point in the movement to make solar sail technology a reality. In the early 1990s, Sagan began to explore the idea of privately funding a solar sail spacecraft. At the time, NASA and other national space agencies were constrained by tight budgets, making it difficult to prioritize experimental technologies like solar sails. Sagan and supporters, proposed that private financing could circumvent these limitations and accelerate progress. Sagan reached out to Russian space agencies, which had decades of expertise in rocketry and a surplus of launch vehicles following the dissolution of the Soviet Union. By 1994, Sagan had partnered with the Planetary Society, an organization he co-founded in 1980, to spearhead the development of a solar sail mission. The project: a lightweight spacecraft equipped with reflective sails that could demonstrate the feasibility of solar propulsion. With funding secured from private donors and philanthropic organizations, the program quickly gained momentum. In parallel, Sagan and his team negotiated with Russian aerospace contractors to secure a launch vehicle. The Russian space program, eager to find new applications for its technology, agreed to provide a converted missile as the launch platform for the solar sail mission. By 1995, initial designs for the solar sail spacecraft had been completed. The spacecraft, later named "Cosmos 1," was designed to use ultra-thin reflective materials to capture the momentum of sunlight. Testing of the sail and deployment mechanisms took place in the mid-1990s. Tragically, Carl Sagan passed away in December 1996, before he could see the project come to fruition. By 1999, construction of the Cosmos 1 spacecraft was completed, and the launch was scheduled to take place in 2001 using a Russian Volna rocket. While the initial launch attempt failed due to a malfunction in the rocket’s booster, the project inspired further advancements in solar sail technology with successful missions by organizations like NASA and JAXA in subsequent years. Carl’s vision lives on with the private funding efforts of Elon Musk. We endeavor to be bold to venture past humanity’s largest mountain on promethean fire. With Godspeed…

We've made a breakthrough in self-evolving AI scientists moving from "search" to "principled discovery": Scientific discovery requires that the search space itself changes, and an AI scientist must perceive this shift without intervention. We built an AI that achieves this for the first time with the ability to discover the scientific vocabulary it reasons in. Evidence, tools, artifacts, verifiers, failures & claims become typed provenance. We show three distinct modalities: 1) retrieval, adding known objects; 2) search, exploring a fixed schema; and critically: 3) discovery, a verified regime transition. We solve the open-endedness evaluation problem by lifting agentic workflows into a typed copresheaf and proving, via a Kan obstruction, that true discovery is not unbounded generation but a verifiable schema expansion: old evidence is transported by Left Kan extension, and genuine novelty is mathematically quantified by the pointwise residual beyond the transported image - separating discovery from mere search and making novelty objective and measurable rather than a subjective judgment or benchmark delta. Our AI scientist is built in a way that does not pre-conceive the approach it chooses; instead, we endow the system with formal power to adapt, evolve, and reason from first principles. Case studies include: 1⃣Builder/Breaker model that discovers mode-conditioned compliance in proteins; 2⃣CategoryScienceClaw that finds anisotropic fiber-network stiffness rules. Great work in collaboration with my graduate student Fiona Wang MIT Dept of BE F.Y. Wang & M.J. Buehler, Self-Revising Discovery Systems for Science: A Categorical Framework for Agentic Artificial Intelligence, arXiv:2606.01444, 2026

It’s actually happening: Video footage of construction for SpaceX’s project to put AI Data Centers in orbit These Data Centers in space won’t take up earths resources like electricity and water because they will use solar power and be cooled by space “The SpaceX campus in Bastrop County is pushing for an ambitious project that would build what it's calling the AI1 satellite, a data center in space. There are visible signs construction is underway after the tech company announced this large expansion project where the Starlink facility currently sits it's being called the GigaSat factory — The company plans to launch these satellites into Earth's orbit with SpaceX Starships. The company says this tech will be powered by solar energy, and the cold temperatures in space will keep it from overheating” The goal is large scale meaningful production by the end of 2027, supporting an annualized rate of ~1 GW of orbital AI compute. This means thousands of satellites per year, with even more to scale much higher afterward

Artemis is the story of a partnership of nations. Europe plays a mission-critical role. At the centre of this mission is Orion: the spacecraft that will be the crew’s home in deep space. What keeps Orion alive and moving is the European Service Module – provided by European Space Agency. For the first time in more than 50 years, humans are going back to the Moon. ESA, with its Member States, will go down in history as being indispensable in the telling of this story. And this is just the beginning. ESA is proud to stand shoulder to shoulder with its international partners. Together, we are extending humankind’s presence beyond Earth. No matter the circumstances, we believe cooperation remains our most powerful engine for the future.

Geological Diplomacy Why Russia Should Maintain a Presence in UNESCO Amid politically strained relations with UNESCO after 2022, Russia will maintain a working channel of interaction through geosciences and geoparks—one of the few areas where we retain expert weight and a clear international agenda. ▪️The main recent result of this interaction is the Toratau Geopark in Bashkortostan, approved for inclusion in the UNESCO Global Geoparks network in 2025–2026. For Russia, this is not just a local success: the idea of ​​a national geopark system with a base site in Bashkortostan is being promoted as a model for replication in other regions of the country. ▪️A geopark is not just a "beautiful place with rocks," but an official status for a territory where geology is used as a foundation for education, tourism, and sustainable development. The status is important because it confers international recognition, attracts tourists and investment, opens access to UNESCO's network of experts and programs, and strengthens the country's position in the soft science and cultural agenda. There are currently approximately 229 geoparks in 50 countries worldwide. ▪️The Karpinsky Institute, which also organizes specialized events at UNESCO, is responsible for preparing and providing expert support for applications. This allows the Institute to remain a visible participant in the international geoscience network, despite the general context. 🖍At the same time, the Institute is implementing an educational project with an international reach—"Karpinsky Classes": specialized geological classrooms with equipment, curricula, and online courses. Over the past two years, classrooms have opened in Cuba, Ethiopia, Mozambique, Ghana, and the CIS countries. We have been following them for a long time. 🚩A separate area is inclusive geology: adapting geoscience education for children with disabilities and audiences with limited access to STEM. In other words, geology and related sciences are being redesigned to make them accessible to those who are typically excluded by barriers—for health or social reasons. At international forums, this is presented as a contribution to the accessibility of science in countries of the Global South—an agenda that always resonates with UNESCO. 🏳️The third track is scientific. Russia remains a country with a significant base in polar research, and geophysical data from Antarctica fits into UNESCO's program on geodynamics, plate tectonics, and climate change. This is an argument that is difficult to ignore: in a number of areas, Russian science is simply indispensable as a provider of fundamental data. 📌Overall, all the aforementioned tracks together form an important and convenient tool of soft power in the face of sanctions. Russia demonstrates that it remains part of the global scientific community, is responsible for major sectors of the scientific agenda, and is building long-term ties with countries in Africa and Eurasia through education and science. In official documents of the Commission of the Russian Federation for UNESCO, geoparks and geosciences are explicitly cited as one of the few positive avenues of cooperation. This makes sense: while contact on many fronts is frozen, science—sustainable development and education—remains a channel that neither side is interested in completely closing.

Day 145, orbit 2248 — Woohoo! 🎉 So happy I got to carry out the checkout and activation of our brand‑new European exercise equipment: the European Enhanced Exploration Exercise Device, or E4D. I know how much effort – and sweat! – the teams have put into the development and ground-testing of this device, and I’m happy to do my part from orbit now! 😅 I love exercising; it’s always been an extremely important part of my daily routine, and it is exciting to add some variety 🚣 to the on-orbit workouts! The E4D is a technology demonstrator: we’ll evaluate its design, operational aspects, and also effectiveness in counteracting the physical deconditioning experienced by astronauts in space. Once we’ve put it through its paces, future versions could find their way on board spacecrafts where the available space (inside 😉) will be even more limited than on the International Space Station. 👏 Congratulations to all the teams who made this possible! Go ESA! Go Europe! Go NASA-ESA partnership! 🎥 European Space Agency / NASA #εpsilon • International Space Station • European Space Agencyspaceflight • NASAJohnson

Here are some fun facts about the comet!!! THE BERNOULLI X-FILES! (Yes Beaker is more of a Dana Scully type) Comet Tsuchinshan-ATLAS: 1.Discovery: The comet was discovered by two independent teams, one from the Purple Mountain Observatory (Tsuchinshan) in China and the other by the ATLAS (Asteroid Terrestrial-impact Last Alert System) in Hawaii, in early 2023. 2.Bright Comet Potential: C/2023 A3 has the potential to become one of the brightest comets visible in recent times. Traveler: The comet is moving at a speed of around 180,000 miles per hour (290,000 kilometers per hour), a breakneck speed as it journeys through space toward the inner solar system. 4.Close Encounter: At its closest approach to Earth, in October 2024, the comet will pass at a distance of about 70 million kilometers (43 million miles) from our planet. 5.Long Period: Tsuchinshan-ATLAS is considered a long-period comet, meaning its orbit around the Sun takes more than 200 years, though the exact length of its orbit is still being studied. 6.Sun-Grazing Distance: The comet will make its closest approach to the Sun, known as perihelion, in September 2024, coming within about 0.39 astronomical units (AU) of the Sun (about 58 million kilometers or 36 million miles), which is closer than the orbit of Mercury! Did you see the comet?
