We’ve long known we’re made of star stuff, but now it turns out that life on Earth might be even more intimately connected to events in deep space than we imagined. Scientists recently reported the first ever discovery of supernova ash – atoms forged in the catastrophic explosion of dead stars – found buried in fossils created by bacteria right here on Earth. And most surprising of all these findings hint at a possible role for supernovae in bringing about mass extinctions, events which have changed the course of life on Earth and may do so again in our future. Today we’re joined at The Star Spot by the discovery team’s Professor Shawn Bishop.

We worry whether our search for extraterrestrial intelligence is looking in the right place. Tony tells us a better question might be whether we’re looking at the right time. But might we be able to catch life ejected into space? Dave shares exciting evidence of enormous water jets coming from Jupiter’s icy moon Europa. Finally Anuj provides an update on an exciting future space telescope that might just be built by little, green… robots.

In 2004 a research team found iron-60 in a ferromanganese crust which provided evidence that the radioactive element was present on Earth as well as some indication of where to look in geological time.

Episode 110: Peering into the Void, with Nico Hamaus

For more info on the podcast, please see our About page.

Feature Guest: Nico Hamaus

nicoAstronomers are no longer avoiding the void. Between the overdense zones of our universe, where most galaxies live, there exist vast regions of near emptiness that can stretch for hundreds of millions of light years. But these voids are not nearly as inconsequential as you might imagine and now they are finally getting the attention they deserve. Astronomers are peering into the void in the hopes of solving a variety of cosmic mysteries, from gleaning critical insights into dark matter to studying unique galaxies found in the voids. Today we’re joined at The Star Spot by Nico Hamaus as we study the spaces between.

Just as we’re learning more about our solar system’s own Kuiper Belt, we’re also discovering that extrasolar systems may harbour similar structures. Dave helps us understand just where such disks may originate. And while it may be just a little world, Anuj tells us dwarf planet Pluto has a surprisingly complex inner (and surface) life.

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.

Episode 106: Is Our Solar System Unique? The Complex Process of Planetary Formation, with Aaron Boley

For more info on the podcast, please see our About page.

Feature Guest: Aaron Boley

boleyIs 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.

Episode 104: The Great Terraforming Mars Debate – Part 4: The Dream, with 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.

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?
