Episode 77: Cosmic Magnetism, with Jo-Anne Brown
from The Star Spot · host wise gerry
Feature Guest: Jo-Anne Brown We all know the Earth has a magnetic field, but it might surprise you to learn that our galaxy has one too. To help us understand the origin of our galactic magnetic field and how cosmic magnetism effects the galaxies in our universe, today we're joined at The star spot by Professor Jo-Anne Brown Current in Space 54.6 million kilometres to Mars. What could go wrong? A hell of a lot, Anuj tells us. Then Tony explains how an unprecedented image of an infant solar system may give us insights into the uniqueness of our home. And finally, Dave says we can learn about the origin of Earth's water... from a white dwarf? About Our Guest Dr. Jo-Anne Brown is Assistant Professor at the University of Calgary. She is involved in the Canadian contribution to the Square Kilometer Array, a radio telescope project which when operational in 2020 will study cosmic magnetism with 50 times our current level of sensitivity. Dr. Brown was a member of the galactic and solar science team for the Planck satellite, a European Space Agency space observatory that was active from 2009 to 2013 and was made famous by its shockingly precise map of the cosmic microwave background.
