Quirks & Questions: why so many kinds of moons in the outer solar system?
A Quirks & Quarks listener wanted to know why there are different types of moons in the outer solar system which includes Jupiter, Saturn, Uranus, and Neptune.
Michael Dudley from Winnipeg specifically wondered why one of Saturn's moons, Titan, has an atmosphere and why Enceladus - another of Saturn's moons - has an ocean bellow its surface.
Dr. Christa Van Laerhoven, a post-doctoral researcher from the Department of Physics and Astronomy at the University of British Columbia answers Michael's question on this week's program
