June 18: The world records of the universe

Professor Bryan Gaensler leads a tour of the extremes of our universe at the S. Walter Stewart Library, 170 Memorial Park Ave., on June 18, 6:30 to 7:30 p.m. in a presentation called The World Records of the Universe.

The records set here on Earth are puny and pathetic compared to those set elsewhere in our vast cosmos. What’s the coldest place in space? What’s the fastest object in the Universe? What’s the biggest object we’ve ever seen in space, and the smallest?

Prof. Gaensler is director of the Dunlap Institute for Astronomy and Astrophysics at the University of Toronto. He has authored over 350 refereed articles on cosmic magnetic fields, supernova explosions and interstellar gas, and tweets as @SciBry on astronomy, science-fiction and rugby.
