Feature Guest: Olivier Guyon
Since he was young his driving passion has been a single mystery: are we alone in the universe? Astronomer Olivier Guyon, who has now been awarded a half a million dollars MacArthur genius grant to answer that question, joins Justin Trottier at The Star spot.
Guyon explains why he's so optimistic he pegs habitable planets at well over 1 in 100 stars. Then the two discuss the cutting edge of discovery, from merely detecting planets to incoming data on oceans, atmospheres and in the not too distant future even biosigns.

Feature Guest: Catherine Hazin
We begin our coverage of the 2013 Canadian Space Summit held in Ottawa in November 2013, with the first of five feature Star Spot interviews with guests at the Summit.
Co-host Denise Fong was pleased to be joined by artist Catherine Hazin at The Star Spot on location. Catherine was showcasing artwork on behalf of over 50 internationally acclaimed space artists as part of the Canadian Space Summit’s space art exhibition: The Inexorable Revolutions of Art.
Denise and Catherine discuss the little trodden territory where science and art overlap and the link between art and space exploration. What is the function that art serves for space exploration and what value does it add to the human interest in observing the Universe and in contemplating our ultimate human frontiers?
Historically in the 1800s, artists accompanied explorers on their excursions to discover the frontier of America, and their contributions to communicating the images of the new lands were prolific and highly valued, from the paintings of Thomas Moran and Albert Bierstadt to Frederick Church, considered the highest paid painter of his day in 1872. More often than not, Church was able to finance his very own exploratory expeditions by painting Earth’s new wonders, like the north pole Aurorae, icebergs of the Arctic sea, and volcanoes in South America.
The wonders of earth when they were first discovered inspired volumes of artwork and depicted places not yet known such as Yellowstone, and Yosemite, now protected national parks in the West. Today these visuals of the previously unknown American Western frontier serve to document our human heritage, and were the basis of immense inspiration, sense of adventure, risk, danger, and of the unknown.
So bringing to the present what we have seen from history, what about the artist’s role today for the human exploration…of space – the final frontier?
Denise and Catherine discuss the renaissance in the connection between art and the nature of exploration and discovery. How relevant is space art today? What function does it serve space exploration? Is it possible for artists’ impressions, and artistic works, to disappear into history just as it did alongside the disappearance of Earth’s new frontier lands? And if we leave out the art, how would space exploration suffer?
Current in Space
Dave shares the first cloudy weather forecast for a Super Earth extrasolar planet. Then Arjun excites us with new data anticipated from the spacecraft GAIA, a super sensitive billion pixel camera set to survey a billion stars in the Milky Way Galaxy (and costing some billion dollars). Finally Benjamin on how disappointment quickly turned to delight when researchers with the Hunt for Extromoons with Kepler (HECK) project made one heck of a discovery: no moon but the least massive gaseous world we've yet found.
About Catherine Hazin

Feature Guest: Christine Wilson
No neighborhood avoids change, and that certainly includes the neighborhood around stars. As the stars that populate galaxies form and develop through their life cycle, how exactly do they change the interstellar medium and drive galaxy evolution? and what larger processes are at play governing the interaction between stars and the galaxies they call home? To help us answer these questions today I’m joined at the star spot by Professor Christine Wilson

Feature Guest: Paul Higgs
What is the answer to “Life, the universe and everything”, Douglas Adams’ great question about the meaning of it all? (Assuming it’s not 42.) We may never have an answer to possibly undefinable questions, but thanks to science, we’re actually getting a little closer to understanding a big part of one our universe’s mysteries: life. Today we're joined at the star spot by Professor Paul Higgs, origin of life researcher.
Paul Higgs and Justin Trottier enjoy a wide ranging discussion, including a focus on recent progress in astrobiological research, the RNA world model and its rival hypotheses to account for life's origins, and the interaction between the SETI search, planetary exploration in our solar system, and studies in our laboratories right here on Earth.
Current in Space
On episode 38 SETI researcher Jill Tarter joined us at The Star Spot. In answer to a question about the likelihood of finding life in the cosmos, she cited two critical discoveries: the growing zoo of extremophiles here on earth and the growing zoo of exoplanets across our galaxy. Anuj and Dave have excited news to share on both those fronts, to copmliment this episode’s feature interview on life’s origins. And Benjamin shares new technological developments toward space-based power generation!

Feature Guest: Matt Dobbs
Dark energy is described as one of the most mysterious phenomenon in our already generally baffling universe. To help us shed some light in the darkness, Matt Dobbs joins Justin Trottier at The Star Spot. His observations of galaxy clusters at the south pole telescope are at the leading edge of our exploration into the unknown.
Current in Space
Benjamin reminds us that astronomers get as close as likely possible to working as time travellers - or at least time voyeurs - and recently discovered the furthest - and hence oldest - galaxy in the universe. Then, as if competing for best entries in the Book of Guinness World Records, Anuj and Victoria tell us about the Boomerang Nebula, a place in our galaxy so cold it makes Toronto winters - and even the afterglow of the Big Bang - seem balmy by comparison. And Dave rounds out our news with the announcement of a major milestone in our search for candidate extrasolar planets in our hunt for Earth's twin.
