Episode 73: Things That Explode, with Christian Ott

For more info on the podcast, please see our About page.

Feature Guest: Christian Ott

???????????????????????????????????????????????????????????????????????????????????????????????????????????????????What do all massive stars have in common. They go boom. Today I’m joined at The Star Spot by Professor Christian Ott. Behind Ott’s highly technical work in numerical relativity and nuclear astrophysics is his love affair with things that explode.

And could the missing pulsar population at the centre of the milky way be explained by, of all things, dark matter? From supernovae, hypernovae and gamma ray bursts to Professor Ott’s self-described “crackpot theory,” you’ll be blown away.

Ganymede has now been added to the short but tantalizing list of moons harbouring internal oceans, following the discovery that the solar system’s largest moon may contain more water than the oceans of Earth. Plus an update on the Dawn spacecraft’s mission to probe the solar system’s early years as it arrival at the dwarf planet Ceres.

Episode 72: The Changing International Landscape for Space Exploration, with Kevin Shortt

For more info on the podcast, please see our About page.

Feature Guest: Kevin Shortt

kevin-shorttIn the second part of their conversation on the international state of space exploration, Kevin Shortt and Justin Trottier tour the globe. They explore the contributions coming from the four corners of our world. China has high ambitions, but can they succeed by going it alone? How do the geopolitical challenges for Israel provide it with unique opportunities? What consequences will a return to a quasi-Cold War state have for international relations between NASA, Russia and the European Space Agency? And as new nations become major players how will our efforts to explore the unknown change in 2015 and beyond?

Episode 71: 2014: An Amazing Year for Space Exploration, with Kevin Shortt

For more info on the podcast, please see our About page.

Feature Guest: Kevin Shortt

kevin-shorttIt’s a year that saw ups, such as the Dawn mission which became the first to study a dwarf planet. It was a year that experienced downs, like the tragic explosion of SpaceShipTwo and questions over the incident’s implication for space tourism. Through the ups and downs 2014 has been one fascinating year for space exploration. For a retrospective on the year that was, and a look at what’s on the horizon in 2015, today i’m joined at The Star Spot by Kevin shortt, the International Relations Officer for the Canadian Space Society.

And on the next episode Kevin Shortt will rejoin me here at The Star Spot for an international survey of the world’s contribution to space exploration. As new nations become major players how will our efforts to explore the unknown change in 2015 and beyond.

The disks of matter that form around mysterious B emission stars are providing astronomers with a unique place to study a ubiquitous phenomenon in our universe. Disks are everywhere and on every scale, from the birth of solar systems to the structure of galaxies. Today we’re joined here at The Star Spot by Carol Jones and Aaron Sigut to conclude our two part series on dynamic and lively B emission stars and the disks that excite them.

Why did asteroid belt member Ceres never form into a fully fledged planet? That’s what Dawn may soon find out when it arrives next month. Is the moon the 8th continent? Anuj explains how mining is getting closer to reaching the final frontier. And worried about aging? Dave shares the discovery of an 11 billion year old planet, still alive and well.

About our Guests

Let’s pick up where we let off with our two guests from Western University. Dr. Carol Jones is Associate Dean of Graduate and Postdoctoral Studies in the Faculty of Science, as well as associate professor and associate dean in the physics and astronomy department. Aaron Sigut is Associate Professor of Astronomy in the Physics and Astronomy Department.

Episode 69: Dynamic Stars and Ubiquitous Disks: Part 1, with Aaron Sigut and Carol Jones

For more info on the podcast, please see our About page.

Feature Guests: Aaron Sigut and Carol Jones

sigutjonesDisks are ubiquitous in our universe. They are found in the spiral arms of galaxies. They are found among new and old stars, whether in the protoplanetary gas associated with stellar births or the black holes which follow many stellar deaths.

Today we have a special treat. I’m excited to be joined by both Carol Jones and Aaron Sigut here at The Star Spot for the first of a special two-part series. We’ll find out why disks are such common features of our universe, and how they figure prominently into a mysterious phenomenon known as B emission stars, which are among the hottest, most energetic and most mysterious of stellar phenomena.

Episode 67: The Accelerating Universe, with Nobel laureate Brian Schmidt

For more info on the podcast, please see our About page.

Feature Guest: Brian Schmidt

220px-Brian_SchmidtThe 1929 discovery of the expanding universe by Edwin Hubble forever changed our picture of the cosmos and our understanding of our place in the universe. In 1998 we learned that wasn’t the only surprise. That’s when two teams of astronomers announced that the expansion of our universe isn’t slowing down as everyone assumed. Its speeding up. Today we’re joined at The Star Spot by Distinguished Professor Brian Schmidt who won the Nobel Prize for discovering our accelerating universe.

Anuj describes the Orion spaceflight, the first mission since Apollo eventually aimed at deep space. Then Tony wonders if the stuff of life could seed itself on other worlds following the disocvery that DNA returned from the exposure to the vacuum of space in good working order. And Dave extends the lifetime for Mars’ watery past after learning an ancient lake may have lasted tens of millions of years. Finally Celine explains how “cliff-bots” now being tested in the Moroccan desert may one day dig up deposits left over from such long extinct bodies of water.

About our Guest

Dr. Brian Schmidt is Distinguished Professor at the Australian National University Mount Stromlo Observatory and holder of an Australian Research Council Federation Fellowship. In 2011 Schmidt received the Nobel Prize in Physics for his co-discovery that the universe isn’t merely expanding, it’s actually accelerating in its expansion. Shmidt is Fellow of the Royal Society, a recipient of the Pawsey Model, the Dirac Medal and the Shaw Prize in Astronomy.

Dave mesmerizes us with the carnival funhouse like effect around black holes, where the warping of space and time is so intense you can see the front and back of blackholes simultaneously. Celine discusses an upcoming unmanned mission to drill the moon for lunar samples and establish the viability of a future human outpost. And while you may have heard of the Great Red Spot on Jupiter, Tony wonders if the entire spot is red, why it’s red and why so little else on the gas giant shares the iconic colour. Finally Yonna brings us news of Europe’s first space plane set to launch shortly.

About our Guest

Alison Sills is Professor of Physics and Astronomy at McMaster University in Hamilton, Ontario. She received her PhD from Yale University and held postdoctoral positions at the Ohio State University and the University of Leicester in the UK. She studies weird stars in odd places, utilizing computation tools to model the evolution of stellar populations. Along with researchers from Canada, the US and Europe, she is an active member of the MODEST collaboration, which stands for MOdelling DEnse STellar Systems.

Feature Guest: Gordon Sarty

sartyMagnetic Resonance Imaging, or MRI, has become a vital technique for diagnosing, treating and monitoring disease. The technology has saved countless lives. But can we ever get MRIs into space where they can help keep astronauts alive and well on the long duration missions of the future? To help us answer that question today Gordon Sarty joins Justin Trottier at The Star Spot.

Anuj explains why some researchers now think dark matter may not be so much exotic as strange… as in strange quarks. Then Celine reports what’s next from the Chinese lunar exploration program following the success of their first round-trip probe to the moon. And Tony brings a startling discovery from studies of primitive meteorites that suggest water was present on our planet much earlier than we thought.

About our Guest

Gordon Sarty is Professor of Biomedical Engineering at the University of Saskatchewan. A renaissance man, Dr. Sarty is also associate member of the university’s departments of physics, medical imaging, and obstetrics, gynecology and reproductive sciences. He combines those interests as a member of a pioneering team working to design portable and eventually space-based MRI machines.
