* Check out the new Thinker's Tavern discussion series athttps://www.instituteforfemininemyth.org/thinkers-tavern  *This week's podcast looks at the figure of Hermaphroditus, son of Hermes (Mercury) and Aphrodite (Venus), and his encounter with the aggressive nymph Salmacis, her prayer turning them into a single being that is both male and female and neither at the same time. While Salmacis is often viewed as an aggressive woman attacking an innocent boy, an inscription at Salmacis' pool in Halicarnassus suggests a very different view of the myth. We explore the idea of the Hermaphrodite as representing the bonds of marriage and ideas about marriage, as well as its connection to Plato's myth of the proto-human in the Symposium. The articles referenced in the podcast were:Kelly, Peter. "Intersex and Intertext: Ovid's Hermaphroditus and the Early Universe," Exploring Gender Diversity in the Ancient World, Allison Surtees and Jennifer Dyer, eds. Edinburgh University Press, 2020. Romano, Allen T. "The Invention of Marriage: Hermaphroditus and Salmacis at Halicarnassus and in Ovid," The Classical Quarterly, Vol. 59, No. 2 (Dec. 2009), pp. 543-561.

Hints of Alien Life, a Galactic Mystery, and Juno's Safe Mode IncidentIn this episode of SpaceTime, we explore groundbreaking revelations suggesting the potential for alien life beyond Earth. Using NASA's Webb Space Telescope, astronomers have detected chemical signatures of dimethyl sulfide and dimethyl disulfide in the atmosphere of the exoplanet K2 18 b, a sub-Neptune world located 124 light years away in the habitable zone of its host star. While these findings are incredibly promising, researchers urge caution as they work to confirm these biosignatures through further observations.A Surprising Spiral Galaxy from the Early UniverseNext, we dive into the discovery of a surprisingly large spiral galaxy dating back 11.4 billion years, which challenges current models of galaxy formation. This massive galaxy, dubbed the "Big Wheel," is three times larger than expected for its time, prompting astronomers to rethink how galaxies can grow and evolve in the early universe. The implications of this finding could reshape our understanding of cosmic structure and formation processes.NASA's Juno Spacecraft in Safe ModeAdditionally, we discuss a recent anomaly that forced NASA's Juno spacecraft to enter safe mode during a close flyby of Jupiter. The spacecraft's precautionary measures allowed it to protect its systems and continue diagnostics, ensuring the mission's ongoing success as it gathers vital data about the gas giant and its moons.00:00 Space Time Series 28 Episode 48 for broadcast on 21 April 202500:49 Potential biosignatures detected on K2 18 b06:30 Implications for the search for extraterrestrial life12:15 Discovery of an ancient spiral galaxy in the early universe18:00 Challenges to current galaxy formation models22:45 Juno spacecraft enters safe mode after anomaly27:00 Summary of recent astronomical discoveries30:15 Science report: Health benefits of sauerkraut and lunar dust solar panelswww.spacetimewithstuartgary.comwww.bitesz.com

Making use of the Gemini North telescope, one half of the International Gemini Observatory, astronomers have characterized the largest-ever early-Universe radio jet. Historically, such large radio jets have remained elusive in the distant Universe. In this podcast, Dr. Anniek Gloudemans discusses how this object was discovered, the follow up observations and what we have learned about radio jets in the early Universe.    Bios: - Rob Sparks is in the Communications, Education and Engagement group at NSF's NOIRLab in Tucson, Arizona. - Anniek Gloudemans is a postdoctoral fellow at NOIRLab working on understanding the formation and evolution of the most massive supermassive black holes in the early Universe. She received her masters degree from the University of Amsterdam in 2019, including an internship at the European Space Agency in 2018. Following this, she obtained her PhD at Leiden Observatory in The Netherlands in 2023, where she studied the low-frequency radio emission of early supermassive black holes. Besides her research, Anniek has a passion for teaching and organizing outreach activities for all ages with a focus on connecting the world through astronomy and raising awareness for climate change.   Links: NORLab Press Release: https://noirlab.edu/public/news/noirlab2506/ Gemini Observatory: https://www.gemini.edu/ NOIRLab social media channels can be found at https://www.facebook.com/NOIRLabAstro https://twitter.com/NOIRLabAstro https://www.instagram.com/noirlabastro/ https://www.youtube.com/noirlabastro   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!

We're experimenting and would love to hear from you!In this episode of 'Discover Daily', we explore groundbreaking developments in AI, cryptocurrency regulation, and early universe water formation. AI startup Anthropic has reached a staggering $61.5 billion valuation after closing a $3.5 billion funding round, showcasing impressive growth with an annual recurring revenue of $800 million. The company's latest AI model, Claude 3.7 Sonnet, introduces innovative 'hybrid reasoning' capabilities, pushing the boundaries of artificial intelligence.The U.S. Securities and Exchange Commission has made a landmark decision, declaring that meme coins generally do not constitute securities under federal law. This significant shift in cryptocurrency regulation has far-reaching implications for the industry, though it comes with important caveats and has sparked debate among regulators.Our main story delves into a revolutionary study published in Nature Astronomy, suggesting that water may have first formed in the universe just 100 to 200 million years after the Big Bang. This discovery challenges our understanding of cosmic evolution and implies that conditions for life may have existed far earlier than previously thought. The research opens up exciting new avenues for investigating the potential for early habitable environments and the emergence of life in the universe.From Perplexity's Discover Feed:https://www.perplexity.ai/page/anthropic-reaches-61-5b-valuat-goxeBd89TI6.SXIGLTUGUQ https://www.perplexity.ai/page/sec-says-meme-coins-are-not-se-yn4ZON0XRmyFivwgjKtRuQhttps://www.perplexity.ai/page/early-universe-may-have-had-wa-fUgTawHmSWGvtriYXLndsA**Introducing Perplexity Deep Research:**https://www.perplexity.ai/hub/blog/introducing-perplexity-deep-research Perplexity is the fastest and most powerful way to search the web.

The 365 Days of Astronomy, the daily podcast of the International Year of Astronomy 2009

Observations using the Dark Energy Camera (DECam) confirm astronomers' expectation that early-Universe quasars formed in regions of space densely populated with companion galaxies. DECam's exceptionally wide field of view and special filters played a crucial role in reaching this conclusion, and the observations reveal why previous studies seeking to characterize the density of early-Universe quasar neighborhoods have yielded conflicting results. In this podcast, Dr. Trysten Lambert discusses how DECam enabled astronomers to reach this conclusion.   Bios: Rob Sparks is in the Communications, Education and Engagement group at NSF's NOIRLab in Tucson, Arizona.   Dr. Trystan Lambert's research career has focused exclusively on extragalactic observational astronomy, exploring both low and high redshift regimes. During his M.Sc. at the University of Cape Town in South Africa, he contributed to the completion of the 2MASS Redshift Survey and developed the galaxy group catalog. He then moved to Chile, where he pursued my Ph.D. at Universidad Diego Portales, studying galaxies and quasars in the epoch of reionization using ALMA and DECam.   Dr. Lambert  is currently a Research Associate at the International Centre for Radio Astronomy Research. He spends his days developing tools to identify large-scale structures in redshift surveys, particularly in the Wide Area VISTA Extragalactic Survey (WAVES). Identifying these large-scale structures allows us to map the distribution of dark matter in the local universe and provides a crucial test bed for current cosmological theories.   NOIRLab press release: https://noirlab.edu/public/news/noirlab2422/ Science News Press Release: https://www.sciencenews.org/article/quasar-zapping-star-formation ICRAR press-release: https://www.icrar.org/quasar-neighbourhoods/ Original Paper: A lack of LAEs within 5Mpc of a luminous quasar in an overdensity at z=6.9: potential evidence of quasar negative feedback at protocluster scales: https://arxiv.org/abs/2402.06870   NOIRLab social media channels can be found at: https://www.facebook.com/NOIRLabAstro https://twitter.com/NOIRLabAstro https://www.instagram.com/noirlabastro/ https://www.youtube.com/noirlabastro   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!

Reported in the Astrophysical Journal Letters, this discovery represents the earliest known merger of supermassive black holes, occurring just 900 million years after the Big Bang. This period, known as the cosmic dawn, is crucial for understanding the formation of the first stars and galaxies and the epoch of reionization.Next, NASA's Mars Perseverance rover has discovered oddly textured, popcorn-like rocks in a formation known as Bright Angel. These rocks suggest the presence of groundwater in Mars' past, and mission managers plan to conduct detailed exploration to uncover their origins.Finally, new insights into the Milky Way's supermassive black hole, Sagittarius A*, have been presented at the 244th meeting of the American Astronomical Society. Using decades of x-ray data, astronomers have uncovered previously undetected flares and echoes, providing valuable information about the black hole's environment and past activity.Follow our cosmic conversations on X @stuartgary, Instagram, YouTube, and Facebook.

Galaxies Actively Forming in Early Universe Caught Feeding on Cold Gas

Researchers analyzing data from NASA's James Webb Space Telescope have pinpointed three galaxies that may be actively forming when the universe was only 400 to 600 million years old. Webb's data shows these galaxies are surrounded by gas that the researchers suspect to be almost purely hydrogen and helium, the earliest elements to exist in the cosmos. Webb's instruments are so sensitive that they were able to detect an unusual amount of dense gas surrounding these galaxies. This gas will likely end up fueling the formation of new stars in the galaxies.“These galaxies are like sparkling islands in a sea of otherwise neutral, opaque gas,” explained Kasper Heintz, the lead author and an assistant professor of astrophysics at the Cosmic Dawn Center (DAWN) at the University of Copenhagen in Denmark. “Without Webb, we would not be able to observe these very early galaxies, let alone learn so much about their formation.”“We're moving away from a picture of galaxies as isolated ecosystems. At this stage in the history of the universe, galaxies are all intimately connected to the intergalactic medium with its filaments and structures of pristine gas,” added Simone Nielsen, a co-author and PhD student also based at DAWN.The universe was a very different place several hundred million years after the big bang during a period known as the Era of Reionization. Gas between stars and galaxies was largely opaque. Gas throughout the universe only became fully transparent around 1 billion years after the big bang. Galaxies' stars contributed to heating and ionizing the gas around them, causing the gas to eventually become completely transparent.By matching Webb's data to models of star formation, the researchers also found that these galaxies primarily have populations of young stars. “The fact that we are seeing large gas reservoirs also suggests that the galaxies have not had enough time to form most of their stars yet,” Watson added.This is Only the StartWebb is not only meeting the mission goals that drove its development and launch – it is exceeding them. “Images and data of these distant galaxies were impossible to obtain before Webb,” explained Gabriel Brammer, a co-author and associate professor at DAWN. “Plus, we had a good sense of what we were going to find when we first glimpsed the data – we were almost making discoveries by eye.”There remain many more questions to address. Where, specifically, is the gas? How much is located near the centers of the galaxies – or in their outskirts? Is the gas pristine or already populated by heavier elements? Significant research lies ahead. “The next step is to build large statistical samples of galaxies and quantify the prevalence and prominence of their features in detail,” Heintz said.The researchers' findings were possible thanks to Webb's Cosmic Evolution Early Release Science (CEERS) Survey, which includes spectra of distant galaxies from the telescope's NIRSpec (Near-Infrared Spectrograph), and was released immediately to support discoveries like this as part of Webb's Early Release Science (ERS) program.

The James Webb Space Telescope and the Early Universe Welcome to The James Webb Space Telescope podcast, where we explore the latest discoveries from the world's most powerful telescope. In today's episode, we're going to be talking about the early universe, and how the James Webb Space Telescope is helping us to understand this mysterious time period.The James Webb Space Telescope is a powerful infrared telescope that can see the light from the very first stars and galaxies that formed in the universe. This is because infrared light is less affected by the expansion of the universe than visible light, so it can travel longer distances without being stretched out.The James Webb Space Telescope can also see through dust and gas, which is important for studying the early universe, because the first galaxies were surrounded by clouds of dust and gas. By studying the early universe in infrared light, the James Webb Space Telescope is helping us to answer some of the most fundamental questions about our universe, such as:How did the first stars and galaxies form?What role did dark matter and dark energy play in the evolution of the universe?The first stars and galaxies formed in the early universe, about 13.8 billion years ago, after the Big Bang. The Big Bang was a massive explosion that created all of the matter and energy in the universe. After the Big Bang, the universe was very hot and dense, but it quickly expanded and cooled.As the universe expanded, gravity began to pull clumps of matter together. These clumps of matter eventually became the first stars and galaxies. The first stars were very different from the stars that we see today. They were much larger and hotter, and they lived for much shorter periods of time.The first stars played an important role in the evolution of the universe. They produced the first heavy elements, such as carbon and oxygen, which are essential for life. The first stars also helped to ionize the gas in the universe, which made it possible for galaxies to form.Dark matter and dark energy are two of the most mysterious substances in the universe. Dark matter is a type of matter that we cannot see directly, but we know it exists because of its gravitational effects on visible matter. Dark energy is a force that is causing the universe to expand at an accelerating rate.Dark matter and dark energy played an important role in the evolution of the universe. Dark matter helped to seed the formation of the first stars and galaxies. Dark energy is causing the universe to expand at an accelerating rate, which is pulling galaxies apart.The James Webb Space Telescope is a powerful new tool that is helping us to understand the early universe. By studying the early universe in infrared light, the James Webb Space Telescope is helping us to answer some of the most fundamental questions about our universe, such as how the first stars and galaxies formed and what role dark matter and dark energy played in the evolution of the universe.

On this episode of Cut to the Chase: we give some of the exciting updates in the world of science. As we approach the Fall of 2023, this year continues to demonstrate that perhaps the scientists still don't know everything there is to know about our planet. Amongst the exciting updates, Dr. Adam Leibovich, our regular contributor on all things physics, has been named Dean of the Arts and Science at University of Pittsburgh.   So major congratulations are in order for that achievement.  Dr. Leibovich goes through three topics in this update. First, we go through the recent experiment with the muon, a subatomic particle, and what that means for the Standard Model. The experiment was run and confirmed the existence of other types of matter and energy that exist in the universe that scientists have not accounted for. So now the search for what these particles, matter, and energy are will keep physicists busy and excited for the future. Second, the James Webb Space Telescope has passed its one year anniversary. Dr. Leibovich goes through a few of the exciting things that the telescope has observed, including the most detailed infrared image of the universe ever created. And third, the ongoing dream of trying to make nuclear fusion a reality reached a recent milestone at the Lawrence Livermore National Laboratory which used 192 lasers to ignite a fusion reaction that produced more energy than was used to trigger it.   Although the old saying that we are “30 years away” from making nuclear fusion commercially viable might still be the case, the milestone was significant as it replicated the achievement of creating more energy than was used to create the reaction. As Dr. Leibovich notes, in the world of science, replication of the experiment is always significant. Now, the world just needs a significant amount of funding and effort to help make nuclear fusion commercially viable. Scaled up nuclear fusion could be a solution towards getting the world off fossil fuels without having to mine the planet for materials to making EVS, solar and wind powered apparatus.

But observations of galaxies with more than one – caused by the merging of two galaxies – have been rare. Now, researchers have combined data from a number of telescopes and satellites, to reveal a pair of supermassive blackholes farther from Earth than any pair detected previously.

John Preskill is the Richard P. Feynman Professor of Physics at Caltech, a title many physicists would cherish. He is widely known in the field for his work as a theoretical physicist spearheading the field of Quantum Computing, where he is Director of Caltech's Institute for Quantum Information and Matter, but his expertise and contributions span a far broader spectrum of topics. His background is in theoretical particle physics, gravitation, and cosmology. As a graduate student, his seminal work on the cosmological implications of magnetic monopoles in Grand Unified Theories helped lead Alan Guth to develop his theory of Inflationary Cosmology, in part to resolve a cosmological conundrum John first elucidated. Since that time, John has explored condensed matter systems and the physics of black holes, made a famous bet with Stephen Hawking, and coined the term “quantum supremacy”, to describe a metric that might reveal the first time a quantum computer resolved a problem that a classical computer could not resolve in a feasible human timescale. As Director the Caltech Institute, John leads one of the most vibrant programs exploring quantum information and quantum computation, and I was happy to have the opportunity to connect again with my old friend and colleague to discuss this rapidly evolving field, about which so much is written in the popular press, and which may impact on all of our lives in the 21st century. In our discussion we tried to separate the wheat from the chaff, to discuss the future of the field, its current state, and challenges and opportunities. In addition, we discussed his own scientific career and the physics areas that have excited him, and what helped drive him to become a physicist in the first place. It was a fascinating discussion and I am sure you will be both entertained, and enlightened. As always, an ad-free video version of this podcast is also available to paid Critical Mass subscribers.
