Episode 153: A Reality Check on Terraforming Mars, with Bruce Jakosky

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

Feature Guest: Bruce Jakosky

Don’t shoot the messenger. The terraforming of Mars has been the dream for many of us who long for a future where humanity has colonized the Red Planet. But is it time to rethink those plans? Today we’re joined here at The Star Spot by Bruce Jakosky, Principal Investigator of the Martian MAVEN Mission, and he’s got some bad news.

Episode 151: New Moons of Jupiter, with Scott Sheppard

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

Featured Guest: Scott Sheppard

On the hunt for the solar system’s elusive Planet X, a team of astronomers accidentally stumbled upon the discovery of 12 new moons of Jupiter. Oops. But it gets even better, because one of these things is not like the others and the way that moon just doesn’t belong might just solve the mystery of lunar origins. To help us understand how one very happy accident is shedding light on the formation of our solar system, today we’re joined here at The Star Spot by the discovery team leader Scott Sheppard.

Thank you for listening to our special 150th Episode of The Star Spot!

Featured Guest: André Müller

Astronomers have taken their first image of an infant planet still developing around a newly formed star. Today we’re joined here at The Star Spot by André Müller, whose team is busy studying this baby world and has already discovered evidence of an atmosphere and possibly even moons, astounding knowledge of such a tiny speck 370 light years from Earth.

On a personal note, I want to dedicate this special 150th episode of The Star Spot to my amazing wife Denise and to our own newborn wonder, Lara Fong Trottier. Thank you for being the stars in my universe.

Episode 148: Does Canada Have a Vision for Space Exploration?, with Chuck Black

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

Feature Guest: Chuck Black

The Canadian Space Advisory Board was tasked with developing a plan to rejuvenate Canada’s declining world standing in space exploration. In 2017 the Board made a bold proposal that Canada designate space a national strategic asset and increase funding necessary for the “revitalization of Canada’s space capacity.”

But when in March 2018 the federal government released its annual budget, these calls were entirely ignored. The chair of the Canadian Space Advisory Board was so disappointed that she took the unusual move of publicly critiquing a government which seemed to be neglecting Canada’s space sector.

With little progress following years of industry consultation, where do we go from here? To help us understand how we got to this point and what can be done to reestablish Canada’s vision for space exploration, today we’re joined at The Star Spot by Chuck Black, the Editor of the Commercial Space Blog.

Episode 147: Postcards From Home

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

Today we turn our telescopes back around to study ourself. Our own solar system is undergoing a conceptual revolution. From its chaotic birth to its fiery end, our solar system is no longer seen as static and isolated. It is now understood to change and evolve, to offer great environmental diversity across its many worlds, and it now seems our solar system even interacts with the rest of the galaxy. In this special interregnum here at The Star Spot, today our news team of Tony, Maya and Dave take us on a journey across the history and the destiny of our solar system.

Episode 146: Supernovae and the Evolution of Life on Earth, with Brian Thomas

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

Feature Guest: 

We have this impression of our planet as isolated from the rest of the universe, our lives cut off from the drama unfolding elsewhere in our galaxy. But what if the course of life’s evolution on Earth was intimately connected to events well beyond our solar system. It now seems likely that supernovae hundreds of light-years away have profoundly affected our history and may even account for climatic changes just as our species was emerging. Today we’re joined here at The Star Spot by astrophysicist Brian Thomas to explore this fascinating discovery.

Episode 145: Can Sibling Rivalry Explain This Supernova?, with Stuart Ryder

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

Feature Guest: Stuart Ryder

When a massive star explodes in a supernova, it tends to gobble up all the attention. But what happens when that star has a binary companion with its own story to tell? That’s exactly what happened last month when the Hubble Telescope captured the first image of the surviving stellar companion to a supernova, and it turned out to be more than just a passive observer. Today we’re joined at The Star Spot by the discovery team leader Stuart Ryder to tell us how sibling rivalry might account for the origin of one unusual type of supernova.
