Sara Seager, a world authority on the study of atmospheres of extrasolar planets joins Justin Trottier to share how cutting edge research is pushing the frontier not just in discovering planets beyond our solar system, but in starting to actually characterize their attributes like atmosphere and composition.
The two discuss the startlingly diverse zoo of objects out in our galaxy, Dr. Seager's excitement being part of the team that detected evidence of the first extrasolar planet atmosphere, and most tantalizingly, how we are now on the cusp of being able to identify biosignatures of life as we home in on other Earths out there in space. Dr. Seager also provides some insider information on the pseudoscientific History Channel program Ancient Aliens, on which she's appeared on several occasions.
On January 25th of this year, the Astronomy and Space Exploration Society based out of the University of Toronto hosted its 10th annual Expanding Canada’s Frontiers symposium, a series that has become a fixture in the city for celebrating achievements in astronomy and space sciences and engineering. This 10th event in the series was a real landmark, focused on the search for life beyond Earth. The Star Spot caught up with Dr. Seager following her presentation on campus, and on an upcoming episode of The Star Spot we will be joined by NASA's eminent astrobiologist, Dr. Chris McKay, another of the symposium's keynote speakers.
About Dr. Sara Seager
Dr. Sara Seager is currently professor of astronomy at the Massachusettes Institute of Technology and a world authority on the study of atmospheres on extrasolar planets, the subject of her Harvard University PhD. She's the recipient of the Helen B. Warner Prize from the American Astronomical Society, Harvard’s Bart J. Bok Prize in Astronomy, and named to Popular Science’s Fifth annual brilliant 10. Even more cool, NASA’s planetquest has described Dr. Seager as “an astronomical indiana jones.”

Episode 23: Studying the Universe's Large Scale Structure from the South Pole, with Keith Vanderlinde
Keith Vanderlinde joins Justin Trottier at The Star Spot to share his Antarctica experience, studying the Cosmic Microwave Background radiation from the South Pole Telescope. He explains the ambiance, challenges and thrills of working in cold and darkness for nearly a year. The two then discuss how the origin and evolution of large scale structure in the universe can be read from imprints left on the first light released into space, and what we can learn about dark matter and dark energy from characterizing the universe’s earliest galaxy clusters.
Keith Vanderlinde is Global Scholar with the Canadian Institue for Advanced research and Assistant Professor in the University of Toronto's Department of Astronomy and Astrophysics and Dunlap Institute for Astronomy and Astrophysics. Vanderlinde previously worked as a Research Assistant at the Kavli Institute for Cosmological Physics in Chicago. He participated in crafting a number of science exhibits at Chicago’s Adler Planetarium and Museum of Science and Industry. More recently he was stationed for nearly a year in Antarctica working with the South Pole Telescope to study data from the universe's youngest days taken at one of the coldest locations on earth.
In Current in Space, we look at some notorious recent international examples of space adventures - or sometimes misandventures.
