"Public Lecture Dr. Bryan Gaensler, University of Sydney "Magnets in the sky""
Monday 21 September 2009
Lecture Theatre C1, Building 63, Clayton Campus
One of the more remarkable discoveries made by 20th century astronomers
was that stars, planets, galaxies, and even diffuse interstellar
gas, are all magnetic. These cosmic magnetic fields play a vital
role in controlling how stars and galaxies form, age and evolve.
In addition, this naturally occurring magnetism regulates solar
activity and space weather, protects the Earth from harmful particles,
and is vital for the navigation of birds and other species.
Tonight Professor Bryan Gaensler will open the window for you to
the magnetic Universe. He will explain how we detect and study
magnets in space, even though magnetic fields are invisible even
to the largest telescopes. In the next few years, we will finally
be able to start understanding what creates astrophysical magnets,
what role they play in the Universe's evolution, and how they have
maintained their strength over billions of years of cosmic time.
Following the public lecture (weather permitting), an astronomical viewing
session will be held on the top level of the multi-storey car park at the north
west corner of the Clayton Campus. Please note that clear nights can be very
cold, so please bring warm clothing if you plan to attend the viewing session.
