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: Darren Grant

A one hundred year old astronomical mystery may finally have been solved. Scientists have long wondered just what caused high energy particles called cosmic rays, which arrive on Earth from the far unknown reaches of the universe. But now we have a discovery by the South Pole Neutrino Observatory, appropriately named IceCube, which points the finger at a peculiar phenomena known as blazars. The IceCube Collaboration’s Professor Darren Grant joins us today here at The Star Spot.

Current in Space

Dave reports on the arrival of the Osiris-Rex mission at the asteroid Bennu. Then, when it comes to climate change, desperate times call for desperate measures, such as the plan we hear from Simon to spray chemicals into the atmosphere to reflect the sun’s heat back into space. And Tony explains the possible outcome of an astronomical event so energetic we detected its gravitational waves back in August 2017. Finally Amelia tells us we may have finally come a step closer to understanding what fuels the least-understood type of supernova.
