Episode 12: Quasars: Clues to the Ancient Universe, with Patrick Hall

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

Feature Guest: Patrick Hall

Our guest today is Patrick Hall who joins Justin Trottier at The Star Spot to discuss one of the most energetic, myserious and ancient of phenomana in our universe: quasars. Hall shares his insights into the role quasars played in the evolution of the cosmos and galaxy formation, the mechanisms and physics of their behaviour, and the rare occurence of double quasars. He also describes the eventual fate of our Milky Way Galaxy to merge with Andromeda and produce quasars of our own. Finally, they focus on the Sloan Digital Sky Survey and explore the tremendous opportunities afforded researchers by the growing scale and scope of large sky surveys.

In Current in Space we introduce a cryptic new start-up company Uwingu seeking to fundraising and raise public engagement in space exploration, comment on the enduring fascination with the concept of a space elevator, and pay tribute to one of the greatest explorers of our time – Neil Armstrong.
