Feature Guest: Martin Laforest
Martin Laforest joins Justin Trottier at The Star Spot to discuss the fascinating, complex and bizarre world of the quantum. After describing the Institute for Quantum Computing and the uniqueness of its home, the University of Waterloo and the technological industrial hub of Waterloo, Ontario, the two explore quantum information, cryptography, and the often counter-intuitive theoretical underpinnings of these technological breakthroughs.
Justin then goes through his list of fanciful “science meets science fiction” topics, ranging from quantum teleportation and replication to what possible effect it would have on SETI (Search for Extraterrestrial Intelligence) if aliens have moved on to using quantum encoded signals in their communication.
Finally Laforest comments on how we can harness a topic like quantum computing - which has excited public interest but is inherently complicated - to drum up interest in science.

“When beggars die there are no comets seen. The heavens themselves blaze forth the death of princes.”
- William Shakespeare’s Julius Caesar, Act 2, Scene 2
Feature Guest: David Levy
As we are quickly learning, our solar system is anything but quiet. Today we celebrate the very dynamic and violent place that is our home and immediate neighborhood. In Current in Space we covers the stormy space weather that will greet us shortly when the sun’s magnetic field flips. Then we ask if supposedly dead comets can be resurrected to continue their adventurous and on rare occasions, disastrous, lives.
Finally David Levy joins Justin Trottier at The Star Spot .The giant of comet hunting, who discovered 22 comets, including Comet Shoemaker-Levy 9 which collided with Jupiter in 1994, explains why comets are part of our culture. Following a far ranging interview sprinkled with quotes from Shakespeare, comparisons to cats, and the famous Shoemaker-Levy 9 discovery story, Levy concludes with musings on the grim decline in amateur comet hunting but a hopeful future of comet discovery around extrasolar planets.
About David Levy
Despite the lack of formal training in astronomy or space sciences, David Levy would go on to become a comet hunting legend, discovering or co-discovering 22 comets and publishing 34 books, most on astronomical subjects. He is best known as the co-discover of Comet Shoemaker-Levy 9 which crashed into Jupiter in 1994.
A literature student, he received a PhD from the Hebrew University of Jerusalem in 2010 for his thesis “The sky in early modern english literature.” As I learned during our conversation he enjoys combining his love of comets with his passion for literature, especially Shakespeare, whom he is likely to quote when discussing the importance of comets to our culture.
In 1998 Levy also won a News and Documentary Emmy Award for the script of 3 minutes to impact, a documentary produced for the discovery channel.

Feature Guest: Anne-Marie Weijmans
Dark matter and galaxies turn out to live together as intimate partners. What role did dark matter play in the formation, characteristics and subsequent evolution of galaxies in our universe? And what do our studies of galaxies in turn teach us about the nature of dark matter haloes? To help answer those questions, Dr. Anne-Marie Weijmans joins Justin Trottier at the Star Spot.
The two touch on tantalizing and little known discoveries. Evidence of ancient dwarf galaxy mergers from the movement of stars in our galaxy. Dark matter in our own solar system. And the previously empty space between galaxies turns out to harbor dark matter haloes extending between galactic islands.
Current in Space
Victoria Duncan shares new data from the Mars Reconnaissance Orbiter focused on the Mars northern lowlands showing evidence of fossilized water channels and even an ancient river delta.

Feature Guest: James Robert Brown
We talk a lot at The Star Spot about space, but what, exactly, is space, or time for that matter, and how is it we can know anything at all about our universe and its laws. Some have pronounced the death of philosophy at the hands of science. But are rumours of the discipline's death greatly exaggerated? Philosopher of science James Robert Brown joins Justin Trottier at The Star Spot to discuss the history and philosophy of astronomy.
After introducing the work of philosophy of science, Brown describes the pervasive nature of arguments over the basic nature of space and time, defends Platonism, speaks to the odd power of thought experiments, and provides an update from the frontlines in the Science Wars. Brown also assures us why we should not worry over new attempts to rehabilitate the reality of time. The passage of time is still an illusion after all!
Current in Space
Denise Fong and Jessica Campbell discuss new insight into space wind and why it should matter to you, plus what we're learning from the leftovers of supernovae 1987A in the Large Magellanic Cloud.
About James Robert Brown

Feature Guest: Christopher McKee
Astronomy and science popularizaer Carl Sagan famously declared “We are all starstuff.” He was referring to the discovery that much of the heavier elements in our body formed in the supernovas of dying stars. But after supernovas eject material out into the galaxy, how does that gas - and the rest of the interstellar medium - form into new stars, planets and ultimately us? To help answer that question Christopher McKee joins Justin Trottier at The Star Spot.
The two discuss McKee's contribution to our understanding of the interstellar medium, how the discovery of dark matter effected his model, and what role his work in two very different areas of astrophysics - quasars and the space between the stars - played in advancing his career.

Episode 30: Hacking the Future of Space Exploration, Featuring the International Space Apps Challenge
On the weekend of April 20, 2013, 9000 people from over 80 countries responded to NASA’s call to hack their way towards unique and innovative solutions to special space challenges. A huge array of projects were available, from designing a deployable greenhouse for Mars to building an app to help visualize the topography of the dark side of the moon, to more arts related projects like designing jewellery celebrating the unique properties of 55 Cancri E, a carbon-rich Super Earth planet.
To assist NASA provided scientists and other experts as consultants through live international hookups. The goal? To open up both space exploration and social need while empowering citizens around the world. The event was the international space apps challenge.
On today’s episode of The Star Spot we chat with Jonathan Moneta, an organizer with the Toronto contingent. Then, we speak with William Sellier, a member of the team Green Mars. Green Mars, which answered the challenge of designing the concept for a deployable greenhouse for a future mission to Mars, won one of the two Best in Hardware awards. Finally, we hear from 4 members of the Team known as Museum of Intergalactic Species (Jane Saputra, Charlotte Tang, Kris Nicolaoum, and Mario Dabrowski). Their challenge was to adopt a space-craft, that is to humanize the voyager mission by telling the story of the first human object to leave the solar system in an innovative and interactive way that connected it to people’s lives.

Feature Guest: Seth Shostak
With ever more groundbreaking data coming in from exploratory missions in our own solar system to the burgeoning array of extrasolar planets being discovered on a regular basis, are we getting closer to answering the age old question: Are we alone in the universe? Dr. Seth Shostak, Senior Astronomer with the SETI Institute joins Justin Trottier at The Star Spot to explore the history, current status and future directions in the search for extraterrestrial intelligence.
The two discuss the impact that changes in technology are playing in the nature of the search, how we might overcome the language barrier of communication, and the the potential impact on our civilization of the discovery of a signal. In a broad conversation ranging from musings on the synchronicity problem to whether a response might come from AI rather than carbon-based lifeforms, the SETI enterprise is explored from its many angles: part science, part philosophy, part psychology (both human and alien). SETI might even be, as Dr. Shostak explains, good for the soul.

Fri, 19 April 2013
A quick episode to break up our usual interview-focused show. At The Star Spot today in Current in Space, can we boldly go where no one has gone before, and do so at the speed of light via space-time distortions? Harold White, a scientist at the Johnson Space Center at NASA, thinks the science says such a prospect is a possibility. And what do 1960s cocktails, lego and live music have in common? We give a brief report on Yuri's Night 2013.

Episode 27: The Birth and Death of Stars: Clusters, Supernovae and Gamma-Ray Bursts, with Chris Matzner
Chris Matzner joins Justin Trottier at The Star Spot for a wide ranging conversation focused on the dynamical periods of a star’s life. He shares insights into the fascinating activities occurring in stellar nurseries, based on a major discovery by his research group of a region of our galaxy, dubbed Dragonfish, that hosts the most numerous cluster of young, supermassive stars yet found in the Milky Way. Then jumping ahead Matzner discusses gamma ray bursts, a mysterious phenomena tied to the death of some high mass stars, finally weighing in on an age old question: which should our species fear more - supernovae or gamma ray burst.
