The Star Spot

The Star Spot, with Justin Trottier, is a space themed podcast and radio show focusing on all aspects of astronomy and space exploration. Episodes feature timely news along with fascinating interviews with guests of wide-ranging background: scientists, engineers, artists, politicians, and entrepreneurs. Topics are broad, from the latest space mission to how the universe began to why humans explore.

Feature Guest: Gurtina Besla

The 14th annual Expanding Canada’s Frontiers symposium was hosted on January 27th, 2017 by the Astronomy and Space Exploration Society, a student group based at the University of Toronto. This year’s unique theme was “What Ifs: Is the Impossible, Possible?”!

And now in a special three episode series, we’re joined here at The Star Spot by the event’s keynote speakers as we explore three provocative questions at the cutting edge of astronomy.

First up, on today’s episode Dr. Gurtina Besla asks, what if humans are around to witness the awesome collision of the Milky Way with the Andromeda Galaxy? What would that look like and how would it affect life on Earth?

Current in Space

We always knew life on Earth started soon into the planet's history, but scientists have just set the clock back, and Anuj tells us how unbelievably far back. Then Tony explains how Breakthrough Starshot would design a starship that could travel between stars within a single generation. And while you may have heard about that new exoplanet system with 3 planets in the habitable zone, Dave tells us you won't believe what the sky would look like from the surface!
