The Star Spot (general)

Feature Guest: Ludovic Van Waerbeke

Large scale surveys of the universe are quickly becoming key to making new discoveries at the cutting edge of astronomy. Case in point is the Cosmic Evolution Survey (or COSMOS), which incorporates data from 446,000 galaxies.

Today we're joined at The Star Spot by Ludovic Van Waerbeke whose survey-based research has helped us expand our understanding of the expanding - and accelerating - universe, confirming the existence of an unknown source of energy, or dark energy, and providing a map of the large scale dark matter distribution of the cosmos.

Ludovic Van Waerbeke is Professor of Physics and Astronomy at the University of British Columbia and Senior Fellow of the Canadian Institute for Advanced Research in the Cosmology and Gravity program.

Is our solar system unique? That's becoming a major question for researchers. It turns out solar system formation is a far more complex process than anyone imagined. Gas giants migrate in and out. Planets swap places with each other. And bodies of all shapes and sizes appear at every conceivable distance from their star. To make sense of what might literally be a chaotic system today I’m joined at The Star Spot by Aaron Boley, Canada Research Chair in Planetary Astronomy.

Imagine a starship that could take us out into the galaxy. Meet Icarus Interstellar, a nonprofit foundation working to achieve interstellar travel by the year 2100. Is this science fiction? That’s what I’ll ask Zachary Fejes. His team is tasked with preparing a map that will take us to the stars, and he joins Justin Trottier here at The Star Spot.

We know supernova are among the most destructive and violent events our universe is capable of producing. Now Tony tells us why they may have played a creative role in Earth history. Then Dave shares news of the first exoplanet discovered, alive and well, in a triple star system.

Feature Guest: Chuck Black

Ever consider moving to Mars? The Star Spot did. Along with the University of Toronto Astronomy and Space Exploration Society, we co-hosted a panel event exploring one of the most fascinating questions in which science meets science fiction. The great terraforming Mars debate. 

We were joined by a 5 member panel of experts, representing a wide range of backgrounds. We approached the issue from all angles: physics, astronomy, philosophy, ethics, commerce and politics.

Now over the course of 4 episodes I’m being joined at The Star Spot by each of our guests from that event.

We covered the science of Mars with planetary scientist Paul Delaney. We then turned questions of Martian and Earthling biology with Dr. Olathe MacIntyre. Finally, switching gears, we asked NASA’s planetary protection officer John Rummel if we should terraform a lifeless world.

These have been weighty discussions so in this fourth and final interview with journalist Chuck Black of Canadian Aerospace News we’re going to have a little fun. We’re going to dream of our loftiest vision of a Martian colony and we’re going to ask, if we do opt for colonization, how would we choose who to send as ambassadors of our species.

Now it’s time to switch gears. Even if we could make Mars habitable, we must confront the equally profound question, should we do it? If Mars already habours life, even just microbes, does that make terraforming off limits? If Mars has dormant life, should we reawaken it? And do humans have an imperative to spread life to the barren worlds of our solar system and beyond?

To tackle these biggest of questions today we’re joined at The Star Spot by Professor John Rummel of NASA’s Planetary Protection Subcommittee.

What’s the best way to study the largest volcano in the solar system? Anuj explains. And while every major galaxy has a supermassive black hole at its centre, have you ever wondered just where do they come from? Tony sheds some light.

Feature Guest: Olathe MacIntyre

Ever consider moving to Mars? The Star Spot recently did. Along with the University of Toronto Astronomy and Space Exploration Society, we recently co-hosted a panel event exploring one of the most fascinating questions in which science meets science fiction. Can we terraform Mars to make it habitable? And if we can, should we?

We were joined by a 5 member panel of experts, representing a wide range of backgrounds in order to approach the issue from all angles: physics, astronomy, philosophy, ethics, commerce and politics. Now over the course of 4 episodes we're joined at The Star Spot by each of our guests from that event.

We started, appropriately, with the red planet itself. In our last episode planetary scientist Paul Delaney updated us with the most current understanding of the characteristics of Mars pertinent to the planet’s suitability for life.

Today we look at the biology, turning the focus on us, that is, the biota of Earth. We’ll be asking what we need to change about Mars to make it friendlier to our kind of life? What techniques are available toward that end? And could Earth life itself play a key role in transforming the red planet?

Did you know dung beetles use the Milky Way galaxy for navigation. Don't believe us? Anuj will explain how it works. Then Tony shares how supermassive black holes may unlock the secrets of distant galaxies.

Now, over the next 4 episodes I’ll be joined at The Star Spot by each of our guests from that event.

We start with the science. For the debate over terraforming Mars depends in large part on the attributes of the red planet, on whether it harbours life, and on what technologies are possible to make the planet suitable for a human settlement and even civilization. To set the scene and to share his position in this great debate today we're joined at The Star Spot by planetary science Professor Paul Delaney.

Scientists are getting closer to discovering what dark matter is made of... by ruling out one more possible candidate, explains Anuj. Then Dave announces Kepler has suddenly doubled the number of confirmed exoplanets in our galaxy. And with new research into the overview effect, Tony wonders if the life changing experience enjoyed by astronauts can be brought down to Earth.

As we speak astronomers are busy building the world’s biggest telescope. And when it becomes operational one year from now the globe-spanning Event Horizon Telescope will be aimed at the supermassive black hole at the centre of our galaxy, taking the first ever portrait of this hungry beast lying at the very core of the Milky Way. To help us understand how studying the shadow of supermassive black holes will provide the most rigorous test yet in our understanding of gravity, today we’re joined at The Star Spot by The Event Horizon Telescope’s Professor Feryal Özel

Science fiction fans are familiar with a cloaking device that hides alien ships from an enemy. Now Tony explains how a real life cloaking device could help us hide our entire civilization from prying eyes. And Anuj wonders if Saturn's moons may be younger than we thought - and what that means for our exploration of the solar system.

Feature Guest: Ingrid Stairs

In February scientists announced the first ever discovery of gravitational waves, tiny distortions in the fabric of space-time predicted by Einstein exactly 100 years ago. The Laser Interferometer Gravitational-Wave Observatory, or LIGO, made the historic detection by studying two colliding black holes, but singularities aren’t the only source of gravitational waves.

Here to tell us how pulsars, the lighthouses of the galaxy, can be used to study gravitational waves and help us understand the forces of our universe, today we’re joined at The Star Spot by pulsar authority Ingrid Stairs

We know the late heavy bombardment period was critical to the eventual emergence of life on Earth. But since Earth wasn't the only planet that went through such an ordeal, Anuj explains what that implies for life in the solar system. And Dave shares new evidence of the effect of ancient supernova explosions on our planet.

Feature Guest: Brian Trent

Here’s the ultimate challenge for science fiction. How do you describe the appearance and behaviour of an intelligent alien species when we have no example to go on but us? How can we ever know our portrayal is truly alien and not a projection of our own expectations, hopes and fears? Or has the job of science fiction all along been to hold up a mirror to ourselves? Today we're joined at The Star Spot by Brian Trent, an award-winning science fiction author who manages to blend shockingly unfamiliar alien beings within stories of profound humanity.

Today’s episode of The Star Spot is the third in a three part series featuring interviews with the keynote speakers at the 13th annual Expanding Canada’s Frontier’s symposium, this year on the topic Astronomyths: Science or Fiction?, looking at cosmology and alien life, hosted at the University of Toronto this past January.
