This revelation, based on calculations involving Hawking radiation, sheds light on how black holes and other celestial bodies lose mass over time. We discuss the implications of this research and the fascinating mechanics behind black hole evaporation, including the surprising equivalence in decay rates between neutron stars and black holes.Gravity's Quirks on Asteroid BennuAstronomers have uncovered bizarre gravitational dynamics at play on the near-Earth asteroid Bennu, based on data from NASA's Osiris Rex mission. This small celestial body exists in a delicate balance between gravity and centrifugal forces, creating a unique environment that could lead to its eventual disintegration. We delve into how Bennu's increasing rotation might impact its structural integrity and potential future interactions with Earth.India's Manned Spaceflight AmbitionsThe Indian Space Research Organization (ISRO) has announced plans for its first manned spaceflight, set to launch in early 2027. This historic mission will follow an unmanned test flight of the Gaganyan spacecraft, which is designed to carry a crew into low Earth orbit. We discuss the training and preparations of the selected Indian Air Force pilots and the technical challenges ISRO faces as it embarks on this new frontier in space exploration.www.spacetimewithstuartgary.com✍️ Episode ReferencesJournal of Cosmology and Astroparticle Physicshttps://www.cosmos.esa.int/cosmologyNature Astronomyhttps://www.nature.com/natastronomy/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 63 for broadcast on 26 May 202501:00 New estimates on the universe's end12:30 The strange gravity of asteroid Bennu22:45 India's plans for its first manned spaceflight30:00 Science report: Herpes virus linked to Alzheimer's disease

The prospects that life might exist elsewhere in the universe made headlines last week when it was announced that observations of the exoplanet K2-18b by the James Webb space telescope had revealed the chemical fingerprints of two compounds that, on Earth, are only known to be produced by life. The idea of panspermia, where seeds of life from other worlds may have hitched a ride on asteroids like Bennu and crashed into Earth, may be the key to how we were created, or that perhaps we are the alien life we are looking for.

Scientists have discovered that Earth's core is leaking into the mantle, and it's raising some big questions.

The OSIRIS-REx (Origins, Spectral Interpretation, Resource Identification, and Security-Regolith Explorer) mission has been a resounding success, from taking a sample of asteroid Bennu to returning that sample to Earth. The first in-depth analysis of the space rocks is complete, and the results have been published in Nature and Nature Astronomy. One of the most intriguing results shows that 14 of the 20 amino acids life on Earth uses to form proteins have been found in the sample. This result supports the hypothesis that objects that formed farther from the Sun provided precursor ingredients for life. Join communications specialist Beth Johnson and senior sample scientist Danny Glavin from NASA's Goddard Space Flight Center for a discussion of these important results and their implications for the development of life. (Recorded live on 13 March 2025.)

In 2020, a NASA space probe (called OSIRIS-REx) gently touched down on the asteroid Bennu, some 200 million miles away, and collected rocks and gravel. It delivered that sample to NASA scientists on Earth in 2023. On January 29, 2025 two research papers were published describing their analysis of this asteroid material. It appears to contain some of the chemicals found on meteorites that have hit the earth in the past, but there were some surprises, too. Like the presence of salt crystals that indicate there was water on the asteroid sometime in its past. Basic chemical building-blocks of life were also discovered on Bennu, so we discuss the implications of this on theories about how life first evolved here Earth. Here are links to the two papers: https://www.nature.com/articles/s41586-024-08495-6 and https://www.nature.com/articles/s41550-024-02472-9. ‘Bench Talk: The Week in Science' is a weekly program that airs on WFMP Louisville FORward Radio 106.5 FM (forwardradio.org) every Monday at 7:30 pm, Tuesday at 11:30 am, and Wednesday at 7:30 am.

A billion-dollar spacecraft, a daring deep-space mission, and one of humanity's biggest questions: Where did we come from? NASA's OSIRIS-REx set out to collect a pristine sample from asteroid Bennu, a cosmic time capsule that may hold clues to the origins of life in our solar system. But the journey was anything but easy.Guests:Erica Jawin, postdoctoral research geologist in the Center for Earth and Planetary Studies at the Smithsonian's National Air and Space Museum and member of the OSIRIS-REx missionTim McCoy, curator of meteorites at the Smithsonian's National Museum of Natural History and deputy mission sample scientist for the OSIRIS-REx missionMike Moreau, deputy project manager in the Space Science Mission Operations Project at NASA's Goddard Space Flight Center 

NASA’s OSIRIS-REx mission has returned pristine samples from asteroid Bennu to Earth, and the early results are remarkable. Sample analysts have confirmed the presence of abundant organic compounds, nitrogen-rich material, and evidence of past liquid water, all key ingredients that could help us understand the role asteroids played in delivering the building blocks of life to Earth. This week, we’re joined by Scott Sandford, co-investigator on OSIRIS-REx and a research scientist at NASA’s Ames Research Center. He explores the first two sample analysis papers published by NASA’s OSIRIS-REx team. Then, Bruce Betts joins us for What’s Up, where we look back at humanity’s history of sample return missions.

In Folge 124 geht es um den Weltuntergang. Bzw. eigentlich nicht wirklich, denn wir beschäftigen uns mit dem Asteroid 2024 YR4, der vielleicht im Jahr 2032 auf der Erde einschlagen könnte, das aber vermutlich nicht tun wird und wenn doch keinen Weltuntergang verursacht. Trotzdem haben wir mit Siegfried Eggl gesprochen, einem Experten für planetare Verteidigung und Asteroidenabwehr. Und mit Evi haben wir uns angesehen, was die Science Fiction zum Thema Asteroideneinschlag zu sagen hat.

Everyone knows that a big rock wiped out the dinosaurs. But the danger from an asteroid hitting Earth is not limited to ancient history. To deal with this threat, scientists recently ran an experiment to deflect a potential “city killer.” We'll hear the results of that experiment, and about a visit to another asteroid. In the dusty material NASA brought back from the asteroid Bennu, scientists found the chemical building blocks of life, including many of the amino acids that are found in our cells. Could an asteroid have brought the ingredients for life to ancient Earth? In this episode, we look at our paradoxical relationship with the space rocks that taketh way – and may help giveth - life.

About four and a half years ago, a spacecraft called OSIRIS-REx touched down on the surface of an asteroid called Bennu. It drilled down and scooped up samples of rock and dust and, after several years of travel, delivered those samples back to Earth.Since then, researchers around the world have been analyzing tiny bits of that asteroid dust, trying to tease out as much information as they can about what Bennu is like and where it might have come from. Two scientific papers published this week give some of the results of those experiments. Researchers found minerals that could have arisen from the drying of an icy brine, and a soup of organic molecules, including ammonia and 14 of the 20 amino acids necessary for life on Earth.Dr. Danny Glavin and Dr. Dante Lauretta join Flora Lichtman to talk about the samples, what their analysis is revealing, and what those findings could mean for the hunt for life elsewhere in the solar system.Transcripts for each segment will be available after the show airs on sciencefriday.com.

Bits of Bennu have building blocks of lifeNASA's OSIRIS-REx mission took six years to travel to the asteroid Bennu and return samples to Earth. Now, the first results from the analysis of these rocks are being released. Researchers found evidence of salty water, as well as the elements necessary for life, such as amino acids and the building blocks for RNA and DNA. We spoke with Kim Tait, senior curator of mineralogy at the Royal Ontario Museum in Toronto, and co-author of one of the recent studies, published in the journal Nature.Unlocking the secret of Polar bear de-icingPolar bears spend so much time going in and out of the water that they are considered marine mammals. So when they do this in the frozen Arctic, why are they not covered in ice? A new study reveals the secret turns out to lie in the unique oils they produce that covers their white fur. Julian Carolan, a PhD candidate at Trinity College Dublin, worked with scientists in Norway, Denmark and the U.K. on this paper published in the journal Science Advances.Truffle-hunting dog finds fabulous new fungusA chance discovery has turned out to reveal a new species of North American truffle. These fungi can be desirable and valuable delicacies. An American truffle hunter, Lois Martin, and her  trained dog Monza found a distinctive truffle in a city park that turned out to be a fungus new to science. Although native to North America, it was more similar to European truffles than any found in the Americas. Dr. Greg Bonito at Michigan State University named this new truffle Tuber canirevelatum,  meaning the ‘dog-found' truffle in honour of Monza and other dogs who look for truffles. The work was published in the journal Mycologia.  Voiding your bowels can improve cognitive performanceTo maximize your cognitive function, it might be a good idea to make sure you have a poo first. That's according to a recent study in the journal Sports Medicine and Health Science. In it, scientists found that 9 out of 13 individuals improved how well they did in a mentally taxing cognitive test if they defecated first, whereas all 13 of them improved in their performance when they took a mild laxative the night before. Chia-Hua Kuo, a professor of sports medicine and nutrition at the University of Taipei, said they also saw an increase in oxygen consumption in the test subjects' subnavel regions as they were doing the test, suggesting a previously unsuspected link between the rectum and the brain. Saving species on Earth, preserving them on the moonThe world is in a biodiversity crisis. We're losing species at an unprecedented rate, thanks to climate change, habitat loss, overexploitation and more. We look at some of the more out-of-the-box solutions that are currently in the works – from creating an internet of animals to monitor biodiversity, to saving samples of Earth's biological resources on the moon.We spoke with:Martin Wikelski, the director of the Max Planck Institute of Animal Behavior, honorary professor of ornithology at the University of Konstanz, and the scientific head of the ICARUS project.Mary Hagedorn, a senior research scientist at the Smithsonian Conservation Biology Institute and senior author of a recent paper published in the journal Bioscience proposing a passive biorepository on the moon.

President Trump's nominee for health secretary, Robert F Kennedy Jr, has faced tough questioning at his first confirmation hearing in the US Senate. Also: scientists say asteroid Bennu contains building blocks of life.

In this episode:00:46 Evidence of ancient brine reveals Bennu's watery pastAnalysis of samples taken from the asteroid Bennu reveal the presence of organic compounds important for life, and that its parent asteroid likely contained salty, subsurface water. Collected by NASA's OSIRIS-REx mission, these rocks and dust particles give insights into the chemistry of the early Solar System, and suggest that brines may have been an important place where pre-biotic molecules were formed. As brines are found throughout the Solar System, this finding raises questions about whether similar molecules will be found in places like Jupiter's moon Europa.Research Article: McCoy et al.Research Article: Glavin et al.News: Asteroid fragments upend theory of how life on Earth bloomed14:22 Research HighlightsHow seaweed farms could capture carbon, and why chimps follow each other to the bathroom.Research Highlight: Seaweed farms dish up climate benefitsResearch Highlight: All together now: chimps engage in contagious peeing16:31 How maize may have supported a civilizationResearchers have found evidence of intensive maize agriculture that could help explain how a mysterious South American society produced enough food to fuel a labour-force big enough to build enormous earth structures. It appears that the Casarabe people, who lived in the Amazon Basin around 500-1400 AD, restructured the landscape to create water conserving infrastructure that allowed for year-round production of maize. While this work provides new insights into how the Casarabe may have established a complex monument-building culture, these people vanished around 600 years ago, and many questions remain about their lives.Research Article: Lombardo et al.25:52 DeepSeek R1 wows scientistsA new AI model from a Chinese company, DeepSeek, rivals the abilities of OpenAI's o1 — a state-of-the art ‘reasoning' model — at a fraction of the cost. The release of DeepSeek has thrilled researchers, asked questions about American AI dominance in the area, and spooked stock markets.
