The Star Spot

Feature Guest: Jason Dittmann

Just last month, April 2017, astronomers announced the discovery of an extrasolar planet that has the best shot at harbouring life outside our solar system. To find out what makes LHS 1140b so special and what steps are planned to learn more about this potential alien home, today we’re joined at The Star Spot by the discovery team’s leader Dr. Jason Dittmann.

The famous nearby star Epsilon Eridani harbours a solar system eerily similar to ours, explains Dave. Then Tony shares what we're learning from the clearest image yet taken of the Milky Way's satellite galaxy, the Small Magellanic Cloud.

Feature Guest: Michael Hudson

If you’re like most people you probably think of galaxies as islands of stars, separate and isolated cities of our universe. But it turns out these cities are connected through a vast web of highways known as dark matter bridges. To help us understand the origin and role of this cosmic scaffolding today we’re joined here at The Star Spot by Professor Michael Hudson.

Astronomers have discovered a pulsar that’s coming back from near death, explains Dave. And could the technology for astronaut hibernation be closer than you think? Tony reports.

About Our Guest

Michael Hudson is Professor of Astronomy at the University of Waterloo. His team was the first to capture images of dark matter bridges using a technique called weak gravitational lensing. Hudson holds a PhD in Physics from the University of Cambridge. He received an Outstanding Performance Award from the University of Waterloo and  a Premier’s Research Excellence Award.
