PUBLIC LECTURE: Cooling of Planets and Extra Terrestrial Life

Cooling of Planets and Extra Terrestrial Life Other events...
As a planetary body ages, its internal heat gradually escapes to the surface. In Earth-like bodies, this slow cooling may lead to solidification of iron-rich cores and provide energy sources for magnetic dynamos. In giant planets’ icy moons, this slow cooling may result in freezing of their sub-surface oceans and alter their structure and dynamics.

In this lecture, Professor Li will show recent experimental results of:

1. the iron-sulfur binary system melting at high pressure, which suggest Mercury’s core may actually be “snowing” and which reveal new mechanisms for the planet’s dynamo; 2. the thermal conductivity of water-ices under high pressure, with implications for the thermal evolution history of giant planets’ icy moons.

Implications for extra-terrestrial life will be discussed.
