The Star Spot

Feature Guest: David Hanna

 

Supernovae and hypernove, blazars and quasars: our universe is one exotic place. To help us to make sense of it, today we're joined at The Star Spot by Professor David Hanna.

What do satellites and whales have in common? Anuj explains. Then, Benjamin on how a fight over the reliability of atmospheric extrasolar planet discoveries is a triumph for a science without dogmas.

 

About Our Guests

 

David Hanna is an astrophysicist at McGill University in Montreal. He works in experimental high energy physics, everything from particle accelerators probing the physics of the very small to gamma ray astronomy studying the incredibly large.

 

Hanna was a founding member of the US/Canada collaboration known as STACEE, the Solar Tower Atmospheric Cherenkov Effect Experiment. Yup, that’s why they call it STACEE. STACEE was an experiment dedicated to the study of high energy gamma rays emitted by astrophysical sources and was active observations until 2007.

 

He is currently a member of a new gamma ray collaboration called VERITAS which revels in its even longer name: the Very energetic radiation imaging telescope array system.

 

Through his work in high energy physics, Hanna studies black holes at the centre of active galaxies, pulsars, gamma ray bursts, supernova remnants, dark matter, quasars, hypernova, supernova, unidentified sources. today he joins me to discuss this zoo of the exotica

Feature Guests: Leon Graafland and Elizabeth Howell

On today's episode of The Star Spot we conclude our coverage of the 2013 Canadian Space Summit with special back to back feature interviews. First we're joined by Leon Graafland, a space travel agent with the Adventure Travel Company. Looking for the ride of your life? Leon can sign you up for a space mission and turn you into an astronaut. And once you do, our second guest, space journalist Elizabeth Howell, will want to interview you. Elizabeth will take us to the front lines, from conversations with astronauts to coverage of ground breaking exploration missions.

We worry we won't find habitable extrasolar planets. But could many planets end up being more habitable than Earth? Dave explains why Super Earths might turn out to be Superhabitable? Then Benjamin describes new techniques to probe the interior of asteroids. 

About Our Guests

Leon Graafland is Adventure Travel Specialist with the Adventure Travel Company in Toronto. Leon has lived in Holland, Peru, Canada and South Africa and he’s visited some 60 additional nations. He’s a globe trotter and he’ll set you up with travel to exotic epic destinations like Mount Kilimanjaro, Mount Everest, and Antarctica. But if this world isn’t enough, he’ll also sell you a trip into space.

Elizabeth Howell is a space, science and business reporter. She lists among her most impressive feats covering three Space Shuttle missions, interviewing astronauts while in space, and meeting all the Star Trek captains. She writes for Space.com, Universe Today, Live Science and other publications and is currently working towards a PhD in Aerospace Sciences at the Univerity of North Dakota.
