Have we found Betelgeuse's ‘Betelbuddy?' An astronomical mystery seems to be solved as the long-predicted stellar companion to the bright star Betelgeuse has been detected by a team of researchers led by Steve Howell of the NASA Ames Research Center using the Gemini North telescope in Hawaii. Steve discusses this breakthrough alongside astronomer Andrea Dupree of the Harvard Smithsonian Center for Astrophysics, who has discussed the predictions of this star on previous Science in Action programmes. Malaria is a mosquito-borne disease caused by the parasite plasmodium that kills more than half a million people each year. George Dimopoulos of the Johns Hopkins Malaria Research Institute is using gene editing and gene drive technology to target the parasites as they develop in the guts of mosquito. Can this new method disrupt the malaria parasite life cycle safely and sustainably? Our gut microbiomes are linked to our brains, but how can the bacteria in our colon communicate with our nervous system? M. Maya Kaelberer of the University of Arizona explains this neurobiotic sense, suggesting that the microbes in our large intestine communicate with specialised sensory cells in the gut. These cells send signals up to our brain and regulate our appetite. So, who really decides when you're hungry? Is it you, or is it your microbiome?

In Chile, a powerful new telescope has just given a taster of what we can expect from it later this year, when it will be used to survey the cosmos over a ten-year period. In one image it revealed vast colourful gas and dust clouds swirling in a star-forming region 9,000 light years from the Earth. Housed in the Vera C Rubin Observatory, which sits on a mountain in the Chilean Andes, the telescope is designed to get giant images of the sky about one hundred times larger and quicker than any other existing telescope can achieve. It contains the world's most largest digital camera, the size of a large car. When the Legacy Survey of Space and Time begins towards the end of 2025, the camera will film the entire Southern hemisphere night sky for the next decade, every three days, repeating the process over and over. And it will focus on four areas: mapping changes in the skies or transient objects, the formation of the Milky Way, mapping the Solar System and understanding dark matter or how the universe formed. So, on this week's Inquiry, we're asking, ‘What will Chile's latest telescope tell us about the Universe?'Contributors: Catherine Heymans, Professor of Astrophysics, University of Edinburgh, Astronomer Royal for Scotland, UK Željko Ivezić, Director of Rubin Construction, Professor of Astronomy, University of Washington, USA Dr. Megan Schwamb, Planetary Astronomer, Reader, School of Mathematics and Physics, Queen's University, Belfast, Northern Ireland Dr. Burçin Mutlu-Pakdil, Observational Astronomer, Assistant Professor, Physics and Astronomy, Dartmouth College, New Hampshire, USAPresenter: Charmaine Cozier Producers: Louise Clarke and Jill Collins Researcher: Maeve Schaffer Editor: Tara McDermott Technical Producer: Craig Boardman Production Management Assistant: Liam Morrey Image Credit: Anadolu via Getty Images

The signing of the first ever Memorandum of Understanding between the world-renowned Dublin Institute for Advanced Studies (DIAS) and a Technological University was witnessed by James Lawless, Minister for Further and Higher Education, Research, Innovation and Science. The agreement with the Technological University of the Shannon (TUS) was signed during the celebrations of the Institute's 85th year anniversary, marking its lauded track record since it was set up by Eamon De Valera's Government at the time when its first Director of Theoretical Physics was Nobel-prize winner Erwin Schrödinger. The MOU, signed by Dr Eucharia Meehan, CEO of DIAS, and President of TUS, Professor Vincent Cunnane, will strengthen collaboration in research and innovation between the institutions, with a focus on advancing education and practical knowledge in Artificial Intelligence (AI), Machine Learning (ML) and Computer Vision (CV) and their application to Radio Astronomy. Under the terms of the agreement, two TUS PhD research students, funded by the university, will be appointed DIAS scholars, receiving mentorship from DIAS's world-renowned researchers at Dunsink Observatory and participating in cutting edge research, working on the prestigious I-LOFAR at Birr Castle in Offaly. I-LOFAR stands for Irish Low Frequency Array and it is Ireland's largest radio telescope. It is part of a Europe-wide collaborative astronomy project where Irish scientists and students participate in pan-European research in areas such as: Astrophysics, Cosmic magnetism, Space weather, Solar physics and Big Data and AI applications in astronomy. I-LOFAR generates massive volumes of complex data - often terabytes per day - and CV and ML play a crucial role in how that data is processed, analysed, and interpreted. DIAS and TUS will jointly collaborate on applying High Performance Computing including AI, ML and CV to the detection, classification and characterisation of targeted phenomena in the I-LOFAR data. Initially this will focus on Space Weather / Solar Phenomena but will be expanded to include others. The research outputs will be held in a new centralised Astrophysics storage and High Performance Computing facility at TUS which will benefit all researchers nationally. This new facility will train undergraduates in modelling large datasets. Together TUS and DIAS have also committed to regional educational and industrial workshops to create awareness of the expertise available from the collaboration. The first workshops will be held in conjunction with the LEO office in Offaly. Congratulating both Institutions, Minister James Lawless TD, Minister for Further and Higher Education, Research, Innovation, and Science said: "I warmly congratulate DIAS and TUS on the signing of this important Memorandum of Understanding. Strategic collaboration such as this strengthens our research base and positions Ireland globally at the forefront of technological progress". Dr. Eucharia Meehan, CEO, DIAS said: "We are proud to formalise this collaboration with TUS as we mark 85 years of discovery at DIAS. Since our earliest days, DIAS has been a centre of discovery where students are welcomed and supported in their research endeavours. With this MOU we are further strengthening the research ecosystem to support talent, to foster innovation, and to deliver real impact for our research community and our economy. Building on our track record of developing research infrastructure for the benefit of research in Ireland and further afield, the establishment of a new centralised Astrophysics storage and High Performance Computing facility in partnership with TUS will provide an important resource for current and future generations of researchers." President of TUS, Professor Vincent Cunnane, said: "TUS is proud to embark on this new frontier with DIAS which will enable our students to explore previously undiscovered areas of research in the disciplines of engineering, science and technology. ...

An international team of astronomers led by University of Galway, has discovered the likely site of a new planet in formation, most likely a gas giant planet up to a few times the mass of Jupiter. Using the European Southern Observatory's Very Large Telescope (ESO's VLT) in Chile, the researchers captured spectacular images around a distant young star for the first time in the form of scattered near-infrared light that revealed an exceptionally structured disk. The European Southern Observatory (ESO), the world's foremost international astronomy organisation, has published a stunning view of the new planet-forming disk as their picture of the week. New planet formation observed Photo: Image of the young nearby 2MASS1612 system (also known as: RIK113) taken with the ESO Very Large Telescope in Chile. The image uses near infrared light that was scattered of the dust particles surrounding this young star. While the disk itself is enormous in size (larger than the solar system), it appears tiny on sky (roughly the size of a pinte glass in Galway as seen from Tuam) due to its huge distance of 430 light years from Earth. The structures in the disk indicate that a young gas giant planet is forming in the system. Credit - ESO/C. Ginski et al Video: Simulation of the disk in the 2MASS1612 system. The planet is seen as a bright dot in the simulation that circles the central star within the gap of the disk. The planet drives the spiral arms seen in the disk center. The team of astronomers at the University of Galway will use the James Webb Space Telescope to attempt to take an image of this planet. Credit: C. Pinte/ C. Ginski et al. The disk extends out to 130 astronomical units from its parent star - the equivalent to 130 times the distance between Earth and the Sun. It shows a bright ring followed by a gap centered at roughly 50 astronomical units. For comparison, the outermost planet in our solar system, Neptune, has an orbital distance from the Sun of 30 astronomical units. Inside the disk gap, reminiscent of the outskirts of a hurricane on Earth, a system of spiral arms are visible. While appearing tiny in the image, the inner part of this planet-forming system measures 40 astronomical units in radius and would swallow all of the planets in our own solar system. The study was led by Dr Christian Ginski from the Centre for Astronomy in the School of Natural Sciences at University of Galway and was co-authored by four postgraduate students at the University. Dr Christian Ginski, lecturer at the School of Natural Sciences, University of Galway and lead author of the paper, said: "While our team has now observed close to 100 possible planet-forming disks around nearby stars, this image is something special. One rarely finds a system with both rings and spiral arms in a configuration that almost perfectly fits the predictions of how a forming planet is supposed to shape its parent disk according to theoretical models. Detections like this bring us one step closer to understand how planets form in general and how our solar system might have formed in the distant past." The study has been published in the international journal Astronomy and Astrophysics. Dr Ginski said: "Besides this exceptionally beautiful planet-forming cradle there is something else that I find quite special about this study. Along with the large international team that we assembled for these observations, four of our own University of Galway graduate students were involved in this study. Without the critical help of Chloe Lawlor, Jake Byrne, Dan McLachlan and Matthew Murphy we would not have been able to finalise the analysis of these new results. It is my great privilege to work with such talented young researchers." Chloe Lawlor, PhD student in Physics with a specialisation in Astrophysics, University of Galway, said: "Working with Dr Christian Ginski on the 2MASS1612 paper has been an incredible experience. As an early-career researcher, having the opportunity t...

In this episode we celebrate the 75th anniversary of the Fermi Paradox by looking at a bunch of science capable of preventing and destroying civilizations. We also review our latest not-so-great attempts to land on the moon and launch a rocket that (if it worked) could carry us to Mars.

How are recent DESI experimental results challenging the traditional view of dark energy as a fixed cosmological constant? Are foundational assumptions in Einstein's general relativity limiting progress in theoretical physics? And how do tensions in cosmological measurements, like the Hubble constant discrepancy, reflect deeper issues in physics? In this episode, we'll explore these fundamental questions with none other than Eric Weinstein! Eric is one of the most revered thinkers of our generation. Though not an academic physicist, he proposed a unified theory of physics in 2013, which is supposed to have the potential to explain phenomena that string theory cannot. In a lecture held live at UCSD in April 2025 at the prestigious Astrophysics and Cosmology Seminar, Eric presented an update to his groundbreaking theory. Today, we'll discuss his fascinating theory, the future of physics and academia, and much more.  Eric is an investor, financial executive, and host of The Portal. He and his brother, Bret Weinstein, coined the term Intellectual Dark Web to refer to an informal group of pundits. Eric is a vocal critic of modern academic hierarchies and advocates for advances in scientific theory over an emphasis on experimental results. He proposed a new unified theory of physics in 2013 and has been an active member of the physics community since then.  — Please join my mailing list here

ESA's Solar Orbiter camera probe begins raising its orbit towards the sun's poles, whilst Betelgeuse's elusive buddy continues to sneak past our best telescopes.Earlier this year, Solar Orbiter started to stretch its orbit over greater latitudes – effectively standing on cosmic tiptoes to catch a glimpse of the Sun's poles. This week, we have seen the first ever pictures of them, and as solar scientist Steph Yardley tells us, the views will only get better.Meanwhile, Andrea Dupree of the Harvard Smithsonian Center for Astrophysics and colleagues have had time to study new Hubble and Chandra telescope observations of the iconic star Betelgeuse searching for signs of its hypothesised binary companion – dubbed “Betelbuddy”. The papers that appeared on the Arxiv pre-print server have not yet been fully peer-reviewed, but it seems astronomers will have to keep looking.Humans use machines to read gene sequences as best they can, but it takes time and is not perfect because we do not know what all of it means. Of course nature has its own genome reader – the ribosome. It is this that interprets the genetic instructions contained in our DNA and translates them into actual proteins. Viruses, of course, use it too when a cell gets infected. Shira Weingarten-Gabbay has this week demonstrated how scientists can make use of ribosomes too. Working somewhat in reverse, her team have identified many thousands of proteins previously unknown, that could for example provide targets for future vaccines or antivirals should the need arise.Finally, Nanshu Lu and team in the University of Texas at Austin have been working for some years on two-dimensional wearable electronic “E-Tattoos” to monitor health non-invasively through our skin.

This quantum theory of gravity aims to unify gravity with the fundamental forces of nature, offering potential solutions to some of the most profound questions in physics, including the nature of dark matter and dark energy. We explore the implications of this theory and how it could reshape our understanding of the universe's origins and the behavior of black holes.The Moon's Hot SideRecent findings suggest that the Moon's near side is significantly hotter than its far side, with temperatures reaching up to 170 degrees Celsius higher. This research, based on data from NASA's GRAIL mission, reveals how geological differences between the lunar sides could be attributed to thermal variations in the Moon's mantle. We discuss the potential for these methods to enhance our understanding of other celestial bodies, including Mars and the moons of Jupiter and Saturn.White Dwarf Pulsars: A Stellar DiscoveryAstronomers have made a remarkable discovery of a white dwarf star that emits radio pulses, challenging the notion that only neutron stars can produce such signals. This discovery, reported in Nature Astronomy, opens up new avenues for understanding pulsar mechanisms and their sources across the Milky Way. We examine the significance of this finding and what it means for our knowledge of stellar evolution.www.spacetimewithstuartgary.com✍️ Episode ReferencesReports on Progress in Physicshttps://iopscience.iop.org/journal/0034-4885Naturehttps://www.nature.com/nature/Nature Astronomyhttps://www.nature.com/natureastronomy/Become a supporter of this podcast: https://www.spreaker.com/podcast/spacetime-space-astronomy--2458531/support.00:00 This is Space Time Series 28, Episode 65 for broadcast on 30 May 202501:00 New theory of gravity12:15 The Moon's thermal characteristics22:30 Discovery of white dwarf pulsars30:00 Skywatch: June night skies and the Taurids meteor shower

Progress has been made in our search for alien life. So announced a team of scientists from Cambridge university last week who, using a powerful space telescope, have detected molecules which on Earth are only produced by simple organisms. All in all, it's been a busy week for space science. And all against a backdrop of a US government request to cut NASA's funding. The proposals would need to be approved by the Senate before any cuts are made. But scientists and journalists are asking what it could mean for the future of space science around the world. Science journalist Jonathan Amos and space researcher Dr Simeon Barber discuss.Professor of Planetary Sciences at the Massachusetts Institute of Technology Richard Binzel updates the programme on plans to learn from an asteroid called Apophis, due to fly past us in four years time. Back on Earth, or rather in it, Victoria Gill gets up close to Roman remains which show that gladiators once fought lions. And Tim O'Brien, Professor of Astrophysics at the University of Manchester joins Victoria Gill in the studio to discuss the week's other science news. Presenter: Victoria Gill Producers: Clare Salisbury, Jonathan Blackwell, Debbie Kilbride Editor: Colin Paterson Production Co-ordinator: Josie Hardy

This week, we take a closer look at the weirdly twisty search for a possible planet in our outer solar system. We'll also take in the happy science of aurorae here, at Jupiter, and over Neptune, as well as a bunch of weird discoveries that has some people screaming "It's Aliens!" (it's not aliens). 

We've thrown open the airwaves to you. Marnie Chesterton puts your science questions to Penny Sarchet, Managing editor of New Scientist, Mark Maslin, Professor of Earth System Science at University College London and Catherine Heymans, Astronomer Royal for Scotland and Professor of Astrophysics at the University of Edinburgh. So, if you've ever wondered why planets are round… or what geese are saying to each other as they fly in groups through the sky, listen in for the latest science and some educated hypothesising. Presenter: Marnie Chesterton Producers: Dan Welsh & Debbie Kilbride Editor: Martin Smith Production Co-ordinator: Jana Bennett-Holesworth

How do we detect ripples in spacetime? Neil deGrasse Tyson and comedian Harrison Greenbaum explore black hole collisions, quantum tricks, and how gravitational waves can help us uncover the early universe with MIT physicist and LIGO researcher Nergis Mavalvala.NOTE: StarTalk+ Patrons can listen to this entire episode commercial-free here: https://startalkmedia.com/show/when-black-holes-collide-with-nergis-mavalvala/Thanks to our Patrons Akhilesh Kashyap, George Woods, Alishan Momin, Scott Artyn, Terrance Wallace, justinetaylor1989, David Kupersmith, Asef Karim, Robert Somazze, Micheal Emmer, Jeffrey Cooper, Bigyan Bhar, Gavin TRaber, A Bains, josh burrell, Darius Cruz, Cassandre L Henderson, Liam Higley, Ojakuna, Karen, Anshul Sanghi, Sam Walley, David Eatwell, Psychotacon, Alec Myers, Alfred Rivera, Colby Carmichiel, Tommy, kim kanahele, Robert Breutzmann, Dan Defibaugh, Slyter, Aksheev Bhambri, Chris Topher, Joanna Apergis, Rockington, Patrick Corrigan, AlexKP_, Abi ROdriguez, Shawn Santor, Shanna Johnston, Cleve Dawson, Mohammed Bilal Monnoo, Patrick Laurin, Eric Kaplan, Dr. What, Glen S.
