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.

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.
