Space Nuts Episode: Ryugu's Microbial Mystery, Martian Moon Origins, and Galactic CollisionsJoin Andrew Dunkley and Professor Fred Watson as they explore the latest cosmic revelations. From unexpected microbial contamination of Richie asteroid samples to a groundbreaking theory on the formation of Mars's moons, and the first results from a new instrument on the William Herschel Telescope, this episode is packed with stellar insights and astronomical wonders.Episode Highlights:- Richie Asteroid Contamination: Delve into the challenges of keeping extraterrestrial samples free from Earth's microbes. Despite stringent sterilisation efforts, Richie samples returned by Hayabusa2 show signs of terrestrial contamination, raising questions about planetary protection protocols.- Martian Moons' New Origin Theory: Discover a fresh perspective on how Phobos and Deimos may have formed. A new model suggests that these moons originated from debris of an asteroid that broke apart due to Mars's gravitational forces, offering an alternative to previous impact and capture theories.- Galactic Collisions Unveiled: Explore the first findings from the WEAVE instrument on the William Herschel Telescope. By studying Stefan's Quintet, astronomers reveal the staggering speeds of shock waves from colliding galaxies, shedding light on cosmic interactions and future Milky Way-Andromeda collision scenarios.For more Space Nuts, including our continually updating newsfeed and to listen to all our episodes, visit our website.

Harvey Nininger was on his way home 100 years ago tonight when he saw something that changed his life: a “fireball” — a brilliant space rock burning up in the atmosphere. Nininger taught biology at McPherson College, a small liberal-arts school in Kansas. On his walk home from work, he'd stopped to visit with a colleague when the fireball flashed overhead. It created a lot of questions for Nininger. But he found few answers — no one was studying meteors or meteorites — space rocks that fell to the ground. So Nininger started studying them on his own. That led to a career as a meteor hunter — and the birth of a new field of study: meteoritics. Nininger calculated — wrongly, it turns out — that the meteor of November 9th, 1923, had landed in Colorado. So he set off to find it. He found two meteorites. But both had arrived on Earth much earlier. In 1930, Nininger devoted full time to hunting and studying meteorites. He visited farms, asking people if they had any odd rocks. He paid a dollar a pound for the ones that were meteorites. He sold some of his finds to pay for his work. Later, Nininger opened a museum near Meteor Crater in Arizona. And he got other people involved in the field. Meteoritics became a full academic subject. His work led to a fuller understanding of meteorites, and the larger rocks from which they come. So a chance view of a brilliant meteor led to a new field of study — which continues today. Script by Damond Benningfield Support McDonald Observatory

Until the Apollo moon landings, our only samples of material from space were in the form of meteorites. These meteorites gave us an insight into the origins of our solar system, and might even have provided the complex organic molecules that allowed life to develop on our planet. In this episode we have an awesome chat with noted meteoriticist Greg Brennecka. We explore some of the history of meteorite research, the origins of life on Earth and the free samples of Mars rock that arrived on Earth in the form of meteorites. Greg also gives us a highlights package from his new book 'Impact, How Rocks From Space Led to Life, Culture, and Donkey Kong'.Meteorites might have brought the ingredients of life to Earth, but they've caused some mass extinctions as well. "...the meteorites giveth, and the meteorites taketh away." This is a fascinating insight.Find Greg's book 'Impact' hereFollow Cosmic Coffee Time on Twitter for some special contenttwitter.com/CosmicCoffTimeYou can request a topic for the show!

Along with Antarctica and the Sahara, one of the best places on earth to find meteorites is the dry lakebeds of New Mexico. So it's not surprising that among the first institutions established to study these extraterrestrial visitors is UNM's Institute of Meteoritics . The Institute celebrates its 75th anniversary with a Symposium on October 24 and 25 that includes an open house at the Institute's Meteorite Museum . The Director of the Institute, Dr. Carl Agee , joined KUNM to talk about meteorites.

Because of space physics, one faraway asteroid is likely the progenitor of almost a third of all the meteorites on Earth.

Melvyn Bragg and guests discuss the Second Law of Thermodynamics which can be very simply stated like this: "Energy spontaneously tends to flow from being concentrated in one place to becoming diffused and spread out". It was first formulated – derived from ideas first put forward by Lord Kelvin - to explain how a steam engine worked, it can explain why a cup of tea goes cold if you don't drink it and how a pan of water can be heated to boil an egg.But its application has been found to be rather grander than this. The Second Law is now used to explain the big bang, the expansion of the cosmos and even suggests our inexorable passage through time towards the 'heat death' of the universe. It's been called the most fundamental law in all of science, and CP Snow in his Two Cultures wrote: "Not knowing the Second Law of Thermodynamics is like never having read a work of Shakespeare".What is the Second Law? What are its implications for time and energy in the universe, and does it tend to be refuted by the existence of life and the theory of evolution?With John Gribbin, Visiting Fellow in Astronomy at the University of Sussex; Peter Atkins, Professor of Chemistry at Oxford University; Monica Grady, Head of Petrology and Meteoritics at the Natural History Museum.
