The Star Spot

Feature Guest: Paul Delaney

The next time you look up at the night sky, struck dizzy by the sheer number of stars shining down on you, here’s something to consider. On average each star host at least one planet. That’s the accumulated result of our exoplanet hunting efforts to date. To help us explore the implications of this profound discovery and to make sense of our zoo of exoplanets, from Super Earths to Hot Jupiters and everything in between, Professor Paul Delaney joins Justin Trottier at The Star Spot.

We’ve focused much attention on exoplanet discoveries. Today we step back and provide some perspective. Professor Delaney takes us from the earliest planet hunting pioneers all the way to the latest technological developments that are pushing the distance of our planetary discoveries, reducing the size of the objects we are able to detect, and leading us on to the next frontier: exoplanet atmospheres.

Professor Delaney explains his surprise at the ubiquity of so-called “rogue planets” and shares his touching story of becoming an astronomer despite living with albinism. Though in his own words he does not have a good relationship with the sun, he has fostered a great one with the stars, and he works to share his infectious enthusiasm with the world.

Current in Space 

Dave shares the discovery of an exoplanet found near the all important “frost line,” the first time we’ve found a planet with a history potentially similar to that of Jupiter. Benjamin describes how the upcoming James Webb Space Telescope may search the atmosphere of exoplanets for signs of life - including long self-destructed life! Closer to home, Anuj tells of a new spacecraft being sent to sample an asteroid for organics. And Denise wonders if the next space race will be far more crowded than the last one.
