The Star Spot

International Astronomy Day 2014 occurred on Saturday, May 10. The Star Spot celebrated at the David Dunlap Observatory in Richmond Hill, Ontario, which boasts the largest telescope in Canada. The Dunlap Observatory was once the second largest telescope in the world, second only to the Hooker Telescope at the Mount Wilson Observatory, famously used by Edwin Hubble to discover the expanding Universe. The Dunlap is now used purely for educational and outreach purposes and is maintained by the Royal Astronomical Society of Canada, Toronto Centre, one of The Star Spot's affiliated organizations.   

On this episode of The Star Spot we bring you highlights from our event, Stump the Astronomer, held as part of International Astronomy Day 2014 at the Dunlap Observatory.

How big is space?  Is string theory the end of physics? Will an elevator ever take us into space? what happens if a regular matter black hole comes into contact with an anti-matter black hole? And most critical of all, was our astronomer stumped?

Current in Space

Ben introduces us to the sun's potential first known sibling, a star that is now thought to have formed in the same nursery, or nebulae, as our own. Then Anuj explores the search for hidden ancient impact craters on Earth and what they tell us about the history of our planet - and the evolution of life. And back to Ben for continued breaking news coming from the study of gravitational distortions of the early universe.

About our Guest

We were very fortunate to put on the spot at the star spot our resident amateur astronomer Ed Hitchcock, also known as SciTeacherEd on twitter. Ed Hitchcock is an evolutionary biologist, high school science teacher and volunteer telescope operator at the Dunlap Observatory. He blogs about science education at teachscience.net and amateur astronomy at BudgetAstronomer.ca. He describes himself as a life long science geek
