Podcasts about planet formation

Professor Fred Ciesla from the Department of Geophysical Sciences is on The Course this week to share how his career path to becoming a geophysical sciences professor started when he was a child. He was inspired to study astronomy after seeing stars, in particular Venus, glowing in the night sky. His path led him to Cornell, NASA, and finally to UChicago, where he met various important mentors along the way and worked on various research questions. Tune in to hear Professor Ciesla's sharing and his curiosity about whether there is life elsewhere.  

Space rocks from all over the world, including pristine material which has been collected directly from asteroids in our solar system. is being analysed in Copenhagen by Professor Martin Bizzarro. He is Director of Center for Star and Planet Formation at University of Copenhagen and explains what we can learn from the material collected in space compared to meteorites on Earth. Will we have a space mining industry in the future? How old is our solar system really? Do we find traces of life on pristine asteroids in space? Martin Bizzarro is interviewed by science journalists Jens Degett from Science Stories. Photo: Jens Degett The podcast on rocks in space is supported by Otto Mønsted Foundation og Thomas B. Thriges Foundation.

AccuWeather Daily brings you the top trending weather story of the day - every day.

I denne episode har RumSnak-redaktionen været på udflugt på Center for Star and Planet Formation (StarPlan), på Øster Voldgade i København. Centrets formål er selvfølgelig at gøre os klogere på, hvordan stjerner og planeter opstår, inklusive Jorden selv. Og netop Jordens oprindelse er fokus for en række nyere af centrets artikler – artikler som mener at kunne påvise at Jorden blev dannet meget hurtigere end man hidtil har antaget, på få millioner år i stedet for 50-100 millioner år. For at høre mere om teorierne besøgte vi professor og centerleder Martin Bizzarro i hans lune hjørnekontor på Starplan, og fik også en kort rundtur til nogle af de laboratorier, blandt andet kemilaboratoriet, hvor Martin og hans kolleger undersøger meteoritter og støvprøver fra asteroider. Martin har nemlig tidligere været med til at analysere materiale fra asteroiden Ryugu og venter også på en lille leverance fra asteroiden Bennu… God fornøjelse

How do planets form out of dust particles? And what does that have to do with fluid dynamics? To find out, Dr. Charles Liu and co-host Allen Liu welcome astrophysicist Dr. Holly Capelo from the University of Bern in Switzerland.   As always, though, we start off with the day's joyfully cool cosmic thing, which takes us to the Observatory of Paris, where a group of scientists are delving into the formation of planetesimals. What are they, where do they come from, and when do they form? Holly dives right in to explain what we know about them, and what forces might prevent planetesimals from growing into planets. Along the way, she blows Chuck's mind about planet formation and accretion disks.   Next, Dr. Capelo uses Alice in Wonderland to help describe her extensive experiments flying on Novespace's Air Zero-G (the European equivalent of NASA's “Vomit Comet”) flying in parabolas in order to better understand fluid dynamics, aerodynamic drag and the impact of freefall, microgravity and hypergravity on dust particles.   For our first question this episode, Allen asks Holly about what makes up interplanetary debris, now and in the past. You'll learn all about ice lines, the impact of vacuum on water vapor and dust particles, minimum mass solar nebulas, density distributions and how much debris there actually is floating around our solar system.    You'll also hear a little bit about Holly's other experiences, as a dancer, and how grad school made it harder to stay in shape.   Our next question revolves around the possible atmospheres of the Moon, comets and planetesimals. Holly explains how we have evidence of transitory events, like outgassing. She also tells us about an upcoming “comet interceptor” mission to study comets that will place a satellite at a Lagrange point to wait for a comet to enter our solar system and then fly to meet it.    If you'd like to know more about Holly and her experiments, you can follow her on Twitter @hollycapelo.   We hope you enjoy this episode of The LIUniverse, and, if you do, please support us on Patreon.    Credits for Images Used in this Episode: Accretion disks imaged by ALMA – European Southern Observatory, CC BY 4.0 Phase diagram of water – Hokanomono & Cmglee on Wikimedia, CC BY-SA 3.0 Novespace's Air Zero-G aircraft – Marc Lacoste, CC BY-SA 4.0 Illustration of Rosetta at comet 67P – Deutsches Zentrum für Luft- und Raumfahrt, CC-BY 3.0

Star & planet formation: Upcoming opportunities in the space-based infrared by Floris van der Tak. on Wednesday 30 November While ALMA and JWST are revolutionizing our view of star and planet formation with their unprecedented sensitivity and resolution at submillimeter and near-IR wavelengths, many outstanding questions can only be answered with observations in the thermal (mid- and far-) infrared domain. Many of these questions require space-based observations, to achieve the necessary sensitivity and/or wavelength coverage. In particular, how do interstellar clouds develop filamentary structures and dense cores? What are the masses and luminosities of objects at the earliest stages of star formation? What are the gas masses of planet-forming disks, and how do these disks disperse during planet formation? How is refractory and volatile material distributed within the disks, and how does this evolve with time? This article reviews how upcoming and planned balloon-borne and space-based telescopes for the mid- and far-infrared will address these questions, and outlines which further missions will be needed beyond 2030, when the ELTs will be in full operation. arXiv: http://arxiv.org/abs/http://arxiv.org/abs/2211.15149v2

Nitrogen as a Tracer of Giant Planet Formation I : A Universal Deep Adiabatic Profile and Semi-analytical Predictions of Disequilibrium Ammonia Abundances in Warm Exoplanetary Atmospheres by Kazumasa Ohno et al. on Wednesday 30 November A major motivation of spectroscopic observations of giant exoplanets is to unveil planet formation processes from atmospheric compositions. Several recent studies suggested that atmospheric nitrogen, like carbon and oxygen, can provide important constrains on planetary formation environments. Since nitrogen chemistry can be far from thermochemical equilibrium in warm atmospheres, we extensively investigate under what conditions, and with what assumptions, the observable NH3 abundances can diagnose an atmosphere's bulk nitrogen abundance. In the first paper of this series, we investigate atmospheric T-P profiles across equilibrium temperature, surface gravity, intrinsic temperature, atmospheric metallicity, and C/O ratio using a 1D radiative-convective equilibrium model. Models with the same intrinsic temperature and surface gravity coincide with a shared "universal" adiabat in the deep atmosphere, across a wide equilibrium temperature range (250--1200 K), which is not seen in hotter or cooler models. We explain this behavior in terms of the classic "radiative zero solution" and then establish a semi-analytical T-P profile of the deep atmospheres of warm exoplanets. This profile is then used to predict vertically quenched NH3 abundances. At solar metallicity, our results show that the quenched NH3 abundance only coincides with the bulk nitrogen abundance (within 10%) at low intrinsic temperature, corresponding to a planet with a sub-Jupiter mass (< 1 MJ) and old age (> 1 Gyr). If a planet has a high metallicity ($ge$ 10$times$ solar) atmosphere, the quenched NH3 abundance significantly underestimates the bulk nitrogen abundance at almost all planetary masses and ages. We suggest modeling and observational strategies to improve the assessment of bulk nitrogen from NH3. arXiv: http://arxiv.org/abs/http://arxiv.org/abs/2211.16876v1

Nitrogen as a Tracer of Giant Planet Formation II : Comprehensive Study of Nitrogen Photochemistry and Implications for Observing NH3 and HCN in Transmission and Emission Spectra by Kazumasa Ohno et al. on Wednesday 30 November Atmospheric nitrogen may provide important constraints on giant planet formation. Following our semi-analytical work (Ohno & Fortney 2022), we further pursue the relation between observable NH3 and an atmosphere's bulk nitrogen abundance by applying the photochemical kinetics model VULCAN across planetary equilibrium temperature, mass, age, eddy diffusion coefficient, atmospheric composition, and stellar spectral type. We confirm that the quenched NH3 abundance coincides with the bulk nitrogen abundance only at sub-Jupiter mass (< 1MJ) planets and old ages (> 1 Gyr) for solar composition atmospheres, highlighting important caveats for inferring atmospheric nitrogen abundances. Our semi-analytical model reproduces the quenched NH3 abundance computed by VULCAN and thus helps to infer the bulk nitrogen abundance from a retrieved NH3 abundance. By computing transmission and emission spectra, we predict that the equilibrium temperature range of 400--1000 K is optimal for detecting NH3 because NH3 depletion by thermochemistry and photochemistry is significant at hotter planets whereas entire spectral features become weak at colder planets. For Jupiter-mass planets around Sun-like stars in this temperature range, NH3 leaves observable signatures of $sim$ 50 ppm at 1.5, 2.1, and 11 $rm {mu}m$ in transmission spectra and > 300--100 ppm at 6 $rm {mu}m$ and 11 $rm {mu}m$ in emission spectra. The photodissociation of NH3 leads HCN to replace NH3 at low pressures. However, the low HCN column densities lead to much weaker absorption features than for NH3. The NH3 features are readily accessible to JWST observations to constrain atmospheric nitrogen abundances, which may open a new avenue to understand the formation processes of giant exoplanets. arXiv: http://arxiv.org/abs/http://arxiv.org/abs/2211.16877v1

Disk dissipation, giant planet formation and star-formation-rate fluctuations in the past three-million-year history of Gould's Belt by Mingchao Liu et al. on Tuesday 29 November Although episodic star formation (SF) had been suggested for nearby SF regions, a panoramic view to the latest episodic SF history in the solar neighborhood is still missing. By uniformly constraining the slope $alpha$ of infrared spectral energy distributions (SEDs) of young stellar objects (YSOs) in the 13 largest Gould's Belt (GB) protoclusters surveyed by Spitzer Space Telescope, we have constructed a cluster-averaged histogram of $alpha$ representing YSO evolution lifetime as a function of the $alpha$ value. Complementary to the traditional SED classification scheme (0, I, F, II, III) that is based on different $alpha$ values, a staging scheme (A,B,C,D,E) of SED evolution is advised on the basis of the $alpha$ statistical features that can be better matched to the physical stages of disk dissipation and giant planet formation. This has also allowed us to unravel the fluctuations of star formation rate (SFR) in the past three-million-year (3 Myr) history of these GB protoclusters. Diverse evolutionary patterns such as single peak, double peaks and on-going acceleration of SFR are revealed. The SFR fluctuations are between $20%sim60%$ ($sim40%$ on average) and no dependence on the average SFR or the number of SFR episodes is found. However, spatially close protoclusters tend to share similar SFR fluctuation trends, indicating that the driving force of the fluctuations should be at size scales beyond the typical cluster sizes of several parsec. arXiv: http://arxiv.org/abs/http://arxiv.org/abs/2211.14637v1

First Steps of Planet Formation Around Very Low Mass Stars and Brown Dwarfs by Paola Pinilla. on Thursday 13 October Brown dwarfs and very low mass stars are a significant fraction of stars in our galaxy, and they are interesting laboratories to investigate planet formation in extreme conditions of low temperature and densities. In addition, the dust radial drift of particles is expected to be a more difficult barrier to overcome during the first steps of planet formation in these disks. ALMA high-angular resolution observations of few protoplanetary disks around BDs and VLMS have shown substructures as in the disks around Sun-like stars. Such observations suggest that giant planets embedded in the disks are the most likely origin of the observed substructures. However, this type of planets represent less than 2% of the confirmed exoplanets so far around all stars, and they are difficult to form by different core accretion models (either pebble or planetesimal accretion). Dedicated deep observations of disks around BDs and VLMS with ALMA and JWST will provide significant progress on understanding the main properties of these objects (e.g., disk size and mass), which is crucial for determining the physical mechanisms that rule the evolution of these disks and the effect on the potential planets that may form in these environments. arXiv: http://arxiv.org/abs/http://arxiv.org/abs/2210.06560v1

Evidence of a signature of planet formation processes from solar neutrino fluxes by Masanobu Kunitomo et al. on Thursday 13 October Solar evolutionary models are thus far unable to reproduce spectroscopic, helioseismic, and neutrino constraints consistently, resulting in the so-called solar modeling problem. In parallel, planet formation models predict that the evolving composition of the protosolar disk and, thus, of the gas accreted by the proto-Sun must have been variable. We show that solar evolutionary models that include a realistic planet formation scenario lead to an increased core metallicity of up to 5%, implying that accurate neutrino flux measurements are sensitive to the initial stages of the formation of the Solar System. Models with homogeneous accretion match neutrino constraints to no better than 2.7$sigma$. In contrast, accretion with a variable composition due to planet formation processes, leading to metal-poor accretion of the last $sim$4% of the young Sun's total mass, yields solar models within 1.3$sigma$ of all neutrino constraints. We thus demonstrate that in addition to increased opacities at the base of the convective envelope, the formation history of the Solar System constitutes a key element in resolving the current crisis of solar models. arXiv: http://arxiv.org/abs/http://arxiv.org/abs/2210.06900v1

Inside-Out Planet Formation VII Astrochemical Models of Protoplanetary Disks and Implications for Planetary Compositions by Arturo Cevallos Soto et al. on Wednesday 14 September Inside-Out Planet Formation (IOPF) proposes that the abundant systems of close-in Super-Earths and Mini-Neptunes form in situ at the pressure maximum associated with the Dead Zone Inner Boundary (DZIB). We present a model of physical and chemical evolution of protoplanetary disk midplanes that follows gas advection, radial drift of pebbles and gas-grain chemistry to predict abundances from 300~au down to the DZIB near 0.2 au. We consider typical disk properties relevant for IOPF, i.e., accretion rates 1E-9 < dM/dt / (Msun/yr) < 1E-8 and viscosity parameter alpha = 1E-4, and evolve for fiducial duration of t = 1E5 years. For outer, cool disk regions, we find that C and up to 90% of O nuclei start locked in CO and O2 ice, which keeps abundances of CO2 and H2O one order of magnitude lower. Radial drift of icy pebbles is influential, with gas-phase abundances of volatiles enhanced up to two orders of magnitude at ice-lines, while the outer disk becomes depleted of dust. Disks with decreasing accretion rates gradually cool, which draws in icelines closer to the star. At

Inside-Out Planet Formation VII Astrochemical Models of Protoplanetary Disks and Implications for Planetary Compositions by Arturo Cevallos Soto et al. on Wednesday 14 September Inside-Out Planet Formation (IOPF) proposes that the abundant systems of close-in Super-Earths and Mini-Neptunes form in situ at the pressure maximum associated with the Dead Zone Inner Boundary (DZIB). We present a model of physical and chemical evolution of protoplanetary disk midplanes that follows gas advection, radial drift of pebbles and gas-grain chemistry to predict abundances from 300~au down to the DZIB near 0.2 au.

Rethinking the role of the giant planet instability in terrestrial planet formation models by Matthew S. Clement et al. on Sunday 04 September Advances in computing power and numerical methodologies over the past several decades sparked a prolific output of dynamical investigations of the late stages of terrestrial planet formation. Among other peculiar inner solar system qualities, the ability of simulations to reproduce the small mass of Mars within the planets' geochemically inferred accretion timescale of

Det var en fuser, da NASA mandag forsøgte at sende Artemis 1-missionen afsted med kæmperaketten Space Launch System. Skal vi simpelthen vænne os til, at NASA's måneraket Space Launch System er så kompleks, at det kun er hver anden gang, det lykkes at sende den afsted? Det spørgsmål forsøger vi at besvare. Vi ser også på, hvorfor det europæiske rumfartagentur vil undersøge, om kæmpemæssige solpaneler i rummet kan hjælpe os med omstillingen til 100 procent grøn energi. Dagens gæster giver deres bud på, om solparker i rummet er vejen frem. Vi hører også fra en forsker, som har fundet støv, der er ældre end solsystemet, og som har været en tur forbi Føtex.

NASAs Curiosity-robot har fejret sit 10-års jubilæum på Mars. Vi ser på, hvordan missionen har formet en dansk forskers karriere, og hvad den har lært os om Den Røde Planet. Senere hører vi fra en Harvard-professor, som vil søsætte en ekspedition til havet ud for Papua Ny Guinea for at finde resterne fra en meteorit, der sprang i luften i 2014. Han håber, at meteoritten slet ikke er en meteorit men et stykke teknologi fra en fremmed civilisation. Til sidst ser vi på De Forenede Arabiske Emirater, for den lille ørkennation har et ambitiøst mål; den vil have en permanent base på Mars i 2117.

Efter solen og Jorden og de andre planeter blev til, er der ikke meget tilbage i solsystemet, som kan fortælle os om, hvordan det alt sammen blev skabt. De få rester, der blev tilbage, er blandt andet kometerne. Vi undersøger, hvordan danske forskere har brugt en rumsonde, som egentlig undersøger Jupiter, til at studere støv fra en komet. Senere finder vi ud af, hvorfor ESA vil sende en rumsonde ud i rummet, som skal ligge på lur, indtil en komet eller et interstellart objekt suser tæt forbi solen. Medvirkende: Anja C.

Today's ID the Future explores with physicist and space telescope expert Bijan Nemati the amazing discoveries that may await us when the singularly powerful James Webb space telescope goes on line in summer 2022. Nemati and host Jay Richards, co-author of The Privileged Planet, discuss the telescope's ability to see far deeper into space than any previous telescope, and further into the past. If all goes well it will be able to see so far into the past, Nemati says, that we will get glimpses of the universe close to when galaxies were first forming, not long after the Big Bang. These glimpses may confirm our most current ideas of early cosmic history and galaxy formation, or turn them on Read More › Source

Welcome to HMSC Connects! where Jennifer Berglund goes behind the scenes of four Harvard museums to explore the connections between us, our big, beautiful world, and even what lies beyond. Today, Jennifer is speaking with Rebecca Fischer, a geophysicist and assistant professor of Earth and Planetary Sciences at Harvard, who studies the formation and deep interiors of Earth and other planets.

After an interstellar asteroid shot past the sun, scientists realized that there’s probably a lot of itinerant rocks out there.

The astroquarks discuss stunning images of a disk of gas and dust around another star giving birth to a planet, more weirdities and oddness in the Earth's magnetic field, the rain on Titan, and so much space news. It's so much exciting stuff that we had to record outside. Catch up on human spaceflight news as well as extraterrestrial lake trivia with your friendly guides to the universe.

Dr. Meredith Hughes is an Associate Professor of Astronomy at Wesleyan University. In her research, Meredith uses large radio telescopes to study how planets form around other stars. After stars are formed, disks of leftover gas and dust go on to form planets. Meredith studies how this process works, the conditions that exist in these early disks, how the disks form planets, and the types of planets that form around stars. Studying this process in other star systems helps us learn more about our own solar system and how it formed.When Meredith isn’t working, you can find her hanging out with her husband, two young kids, and their dog. She also enjoys reading fantasy and sci-fi books, being outdoors, and volunteering in her community. She received her B.S. degree in Physics & Astronomy from Yale University. Afterwards, Meredith attended graduate school at Harvard University where she received her M.A. and Ph.D. degrees in Astronomy. She was awarded a Miller Fellowship to conduct postdoctoral research in the Department of Astronomy at the University of California, Berkeley before she joined the faculty at Wesleyan University in 2013. Meredith has received the Harvard Astronomy Department's Fireman Fellowship for her outstanding doctoral thesis as well as Harvard Astronomy’s Bok Prize for research excellence by a Ph.D. graduate under the age of 35. In addition, she was selected as a Cottrell Scholar in 2018 by the Research Corporation for Science Advancement. In our interview, Meredith shares more about her life and science.

On this episode we (@that_astro_chic and I) talk about the broad strokes of planet formation and the work we’re doing to learn more about the planets around us. We also get into why we had to let Pluto go as a planet (sorry Future) and we also discuss what astrochemistry is, and our search for life on other planets.   We briefly also talk about representation in Physics and what can be done to improve it.

Dr. Ruobing Dong is an Assistant Professor at the University of Victoria (Victoria, BC, Canada) in Physics & Astronomy. His research interests include planet formation. The blog post for this episode can be found at prof-talks.com.

We talk to Parshati Patel who is an Astronomer turned Science Communicator and currently works as an Education and Outreach Program co-ordinator at Western University in London, Ontario in Canada. Parshati talks to us about visualising and understanding how planets form.

How do planets form? What material do the form from? How can we look for life? Will we be able to find something that resembles life? In this episode I talk to Christian Eistrup about simulation on planet formation, Christian is a P.h.D student at Leiden University. We talked about chemistry, accretion discs, what happens if we find Oxygen out there? Are there chemical reactions in planet-forming regions? The post Planet formation and the search for life [Astro et al Ep.9] appeared first on Astronomy et al.

Michael R. Meyer, Institute for Astronomy, Department of Physics, ETH Zurich, delivers a talk about planet formation and conditions for life to exist.

In the fourth part of their discussion, Suzanne Aigrain and Michael Meyer discuss how we move from observations of exoplanets to conclusions about their types and formation. This discussion was conducted at Trinity College, Oxford, on February 12, 2016.

Join Anat Shahar, staff scientist in the geophysical laboratory at the Carnegie Institution for Science, for an exploration of terrestrial planets and a discussion of what laboratory experiments can reveal about the conditions that formed them.

Prof Alessandro Morbidelli of the Observatoire de la Cote d'Azur in Nice gives the 2nd Lobanov-Rostovsky Lecture in Planetary Geology. He talks about the formation of planets in the universe. Morbidelli uses numerical modelling and geochemical and cosmochemical analyses to explain planetary formation within our solar system. He provides a growth history of the Earth, with reference to the specific elements found in the Earth mantle, as well as insight into the composition and timing of moon formation.

Presented by David J. Wilner on 13 February 2015.Where did the Earth come from? How can we know? How can particles no larger than those in smoke come together to make a planet thousands of kilometers wide? Amazingly, radio telescope observations of material surrounding infant stars are starting to show us signs of planet formation in action. This talk will introduce some of the basic ideas and open questions of planet formation, starting with naked eye observations and proceeding to the latest images from giant radio telescopes, including the new international Atacama Large Millimeter Array of 66 antennas sited at 5000 meters altitude in northern Chile.

From forming the moon by budding it off Earth in the last episode, we go to forming the planets by them budding off the Sun. This is mainly an idea by the late Tom van Flandern, and I go through his model, his evidence for it, and the evidence against it, and there is a discussion of some of his surviving advocates.

Dr. Shirley works on a variety of projects studying low-mass and high-mass star formation, the interstellar medium, and chemical evolution within our galaxy and nearby galaxies by combining observations with radiative transfer modeling. He specializes in radio and infrared imaging and spectroscopy utilizing single-dish radio telescopes, interferometers, and space-based observatories.

The star TW Hydrae should be too old to still have planets forming around it, but its gas and dust indicate it still has planetary potential. John Matson reports

The terminal collision defining the end of accretion leaves an indelible mark on the final physical and dynamical properties of a rocky planet. In our own solar system, giant collisions are invoked to explain the observed variations in bulk compositions, spin orientations, moon systems, and asymmetries in crustal thickness. The range of possible outcomes is even greater in extrasolar planetary systems. I will present advances in experimental techniques and numerical methods to understand the physics of giant collisions.

Dr. Eisner is Assistant Professor and Assistant Astronomer at the University of Arizona, a position he has held since 2008. His research interests include: ASTRA: Keck Interferometer Upgrades, Inner Disks Around Young Stars, Extrasolar Planets, Circumstellar Disk Masses in Young Clusters, Protostars, Molecular Layers around Evolved Stars, and Masers Around Young Stars. His lecture was given November 8, 2010.

The solar system formed from a cloud of interstellar gas and dust cloud about 4.6 billion years ago. Life began on earth about 3.5 billion years ago following a period of intense bombardment by asteroid fragments and comets, intense volcanism and finally development of a stable crust and a hospitable atmosphere. Thanks to more powerful telescopes and other state-of-the-art observational methods, we can now see "stellar nurseries" and young stars at various stages of formation. In this talk we’ll learn what triggers star formation in clouds, circumstellar disks and planet formation within the disks, and we’ll discuss early life on earth.

In this talk we’ll learn what triggers star formation in clouds, circumstellar disks and planet formation within the disks, and we’ll discuss early life on earth.

Dr. Jack Lissauer, Space Sciences Division, NASA Ames Research CenterThe observed properties of giant planets, models of their evolution, and observations of protoplanetary disks all provide constraints on the formation of gas giant planets. The four largest planets in our Solar System contain considerable quantities of hydrogen and helium, which could not have condensed into solid planetesimals within the protoplanetary disk. The preponderance of evidence supports the core nucleated gas accretion model of formation of the giant planets. According to this model, giant planets begin their growth by the accumulation of small solid bodies, as do terrestrial planets. However, unlike terrestrial planets, the growing giant planet cores become massive enough that they are able to accumulate substantial amounts of gas before the protoplanetary disk dissipates. During this talk, Dr. Lissauer will present the first models of giant planet formation that account for both the planet's internal energy budget and gas flows within the protoplanetary disk.play video

Why are some clouds dark? Why don't bees stick to their own honey? Why is UV light good for skin conditions, when we know it damages the skin? All these questions and more can be found in this week's Ask the Naked Scientists! Plus, why archaeologists think TB arose as a result of people coming together to live in early villages, and how meteorites lock away the secrets of the solar system. Like this podcast?
