The Star Spot

Feature Guest: Gordon Sarty

Magnetic Resonance Imaging, or MRI, has become a vital technique for diagnosing, treating and monitoring disease. The technology has saved countless lives. But can we ever get MRIs into space where they can help keep astronauts alive and well on the long duration missions of the future? To help us answer that question today we're joined at the star spot by Gordon Sarty

Anuj explains why some researchers now think dark matter may not be so much exotic as strange... as in strange quarks. Then Celine reports what's next from the Chinese lunar exploration program following the success of their first round-trip probe to the moon. And Tony brings a startling discovery from studies of primitive meteorites that suggest water was present on our planet much earlier than we thought.

Feature Guest: Doug Welch

Imagine being able to go back centuries to study the great supernova of the past. Tycho’s nova of 1572 for example. Now we may be able to do the next best thing. Astronomers have discovered a phenomena known as light echoes which allow us to study long ago supernova events from our past and find supernova we never even knew occurred. To help us understand these mysterious light echoes, which can give the illusion of superluminal speeds, Doug Welch joins Justin Trottier at The Star Spot.

The key mechanism for triggering solar flares - potentially harmful events for our civilization - may have been discovered, explains Anuj. Then Tony shares new developments in futuristic skintight shape remembering materials that could revolutionize spacesuits. In an unusual response to the building of a telescope, Celine tells how the Thirty Metre Telescope has been attracting controversy and even opposition. And Dave gives us an update on mysterious organic clouds discovered on Saturn's moon Titan, the only moon in solar system with an atmosphere.

About Our Guest

Doug Welch is Professor of Physics and Astronomy at McMaster University and formerly served as Chair of the department. He received his PhD from the University of Toronto, worked at the Herzberg Institute of Astrophysics’s Dominion Astrophysical Observatory in Victoria, BC. He has been awarded the McNeil Medal of the Royal Society of Canada for the promotion and communication of science and is currently Vice Chair of the Canada-France-Hawaii Telescope Corporation. His research has led him from studies of dark matter to a current focus on supernova light echoes.
