The Star Spot

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

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.

Feature Guest: Raymond Carlberg

When finally operational in 2018 the Thirty Metre Telescope will be the largest telescope ever built, three times larger than the best telescopes operating today. To help us understand how the Thirty Metre Telescope will revolutionize astronomy and cosmology, fuel the study of dark matter and dark energy, further our search for life beyond the solar system, and, simply put, allow us see the limits of the known universe, today we're joined at the star spot by Professor Raymond Carlberg.

We're all familiar with Jupiter's Great Red Spot. Now Tony tells us about Saturday's Great White Spot. And James Bond meets astronomy as Dave documents the transfer of two Hubble class space telescopes from spying on enemy nations to exploring the depths of space.
