Episode 65: Bringing MRIs Into Space, with Gordon Sarty

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

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.

Feature Guest: Doug Welch

Imagine being able to go back centuries to study the great supernovae of the past. Tycho’s nova of 1572 for example. Now we may be able to do the next best thing. Astronomers have discovered a phenomena known as light echoes which allow us to study long ago supernova events from our past and find supernova we never even knew occurred. To help us understand these mysterious light echoes, which can give the illusion of superluminal speeds, Doug Welch joins Justin Trottier at The Star Spot.

Dark matter. Dark energy. String theory. At the frontiers of fundamental physics science seems confronted with mystery and progress is grinding to a halt. But can studying the early universe provide the answer? To help answer that question we’re joined at The Star Spot by Jim Cline. We’ll dive into esoteric concepts like string cosmology and cosmic strings, lumps of massively energetic space time fault lines left theorized to be left over from the Big Bang.

To help settle the debate, and for cutting edge discoveries of brown dwarfs and their startling behaviour, Stanimir Metchev joins Justin Trottier at The Star Spot.

If a brown dwarf is neither a planet exactly nor a star exactly, what is it exactly? What keeps it from collapsing? And since they aren’t necessarily brown, what’s in the name? Metchev and Trottier then discuss the weird and surprising behaviour of brown dwarfs, the ubiquity of their massive storms and their role in helping us study the clouds of extrasolar planets,

Sharing my fascination with the cosmos: The Star Spot partners with Rexdale Summer of Innovation Camp

Over the last couple of years we have had some remarkable accomplishments here at The Star Spot. We’ve interviewed leading scientists, we’ve covered major conferences, we’ve formed meaningful partnerships and we’ve had the pleasure of interacting with our audience directly at many wonderful events.

This month I had another unique opportunity. As a sign of the growth and maturity of our program, The Star Spot came to the attention of the Rexdale Summer of Innovation Camp, a project of the Rexdale Community Hub. The camp is the brainchild of Amra Munawar, a dedicated community activist and a champion of youth education. Working with major sponsors United Way and IBM, she pioneered the idea of a STEM (science, technology, engineering and math) focused summer camp for students in the Rexdale neighborhoods. Rexdale is one of Toronto’s priority neighborhoods, having been identified as a vulnerable community due to higher rates of school drop out  and other metrics. As with so much the answer is education.

On two separate Monday mornings in August I was invited in to lead a 2-hour session on astronomy and space exploration before groups of grade 9 and 10 students. My goal was to give the students some new Canadian role models to emulate by showcasing actual Canadians contributing to the adventure of space. This was easy to do since I have had the pleasure of interviewing several great Canadian leaders in this area: Paul Delaney, Sarah Seager, Bob McDonald, Ralf Gellert, to name a few. But I also wanted to demonstrate how a youth might consider contributing to astronomy and space exploration through both typical and unusual channels. My co-host Denise Fong’s interview with artist Catherine Hazin made for an ideal example.

My first go at this was a good learning experience. It turned out when attempting to wake students up with the early bird Monday morning presentation, best to lead in with engaging icebreakers. On my second attempt I shortened the interview excerpts, but opened with some good old fashioned space trivia followed by a clip of Neil deGrasse Tyson’s overview of the scale of the universe from the first episode of Cosmos: A Space Time Odyssey. That got them hooked.

The experience at Rexdale reminded me of my camp counsellor days, where you aim to be simultaneously entertaining and insightful. Ultimately the goal is less the transfer of particular bits of information and more the desire to leave youngsters with a fascination for a new area of exploration and a thirst for a lifelong adventure of learning and engagement.

The mere report that at least a few of the students were heard considering careers in astronomy and space was enough to tell me I had done my job.

Episode 58: The Mandate of Heaven: Ancient Chinese Astronomy, with David Pankenier

Feature Guest: David Pankenier

The scholar of Chinese science Joseph Needham wrote that “astronomy was a science of cardinal importance for the chinese since it arose naturally out of that cosmic religion, that sense of the unity and even ethical solidarity of the universe.” To help me understand how the mandate of heaven and astrological portents led to the rise and fall of ancient dynasties, and ruled the life and death of the average Chinese, Professor David Pankenier joins Justin Trottier at The Star Spot.

He researches the connection between astromical phenoma and pivotal political and military events in ancient China. Pankenier has published two volumes of translations of many hundreds of ancient Chinese astronomical observations. He has written about ancient Chinese cosmology and released a new book in october 2013, Astrology and Cosmology in Early China: Conforming Earth to Heaven.

Episode 57: Exoplanets: A Retrospective Survey and the Road Ahead, with Paul Delaney

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

Feature Guest: Paul Delaney

pauldelaneyThe next time you look up at the night sky, struck dizzy by the sheer number of stars shining down on you, here’s something to consider. On average each star host at least one planet. That’s the accumulated result of our exoplanet hunting efforts to date. To help us explore the implications of this profound discovery and to make sense of our zoo of exoplanets, from Super Earths to Hot Jupiters and everything in between, Professor Paul Delaney joins Justin Trottier at The Star Spot.

We’ve focused much attention on exoplanet discoveries. Today we step back and provide some perspective. Professor Delaney takes us from the earliest planet hunting pioneers all the way to the latest technological developments that are pushing the distance of our planetary discoveries, reducing the size of the objects we are able to detect, and leading us on to the next frontier: exoplanet atmospheres.

Professor Delaney explains his surprise at the ubiquity of so-called “rogue planets” and shares his touching story of becoming an astronomer despite living with albinism. Though in his own words he does not have a good relationship with the sun, he has fostered a great one with the stars, and he works to share his infectious enthusiasm with the world.

Dave shares the discovery of an exoplanet found near the all important “frost line,” the first time we’ve found a planet with a history potentially similar to that of Jupiter. Benjamin describes how the upcoming James Webb Space Telescope may search the atmosphere of exoplanets for signs of life – including long self-destructed life! Closer to home, Anuj tells of a new spacecraft being sent to sample an asteroid for organics. And Denise wonders if the next space race will be far more crowded than the last one.
