Event Details & Abstract: 

Magnetic fields are ubiquitous in the universe. They control behavior of charged particles that fill most of space. They account for some of the structure observed in the universe. We earthlings live in a bubble in space, shielded by Earth’s magnetic field from direct interaction with most of the energetic particulate matter, some potentially destructive, that fills the solar system. This presentation will start with some historical background and will briefly discuss the generation of planetary magnetic fields, a subject still not fully understood.  Using data from spacecraft that have explored all the planetary bodies of the solar system, the talk will describe magnetic properties of some solar system bodies and how these properties affect their interaction with the plasma that surrounds them.
