Space has an undeserved reputation for being empty. The vast tracts of space between cosmic bodies is permeated by electromagnetic fields and plasmas, whose complex interactions generate significant dynamism in the universe.

At Earth, these interactions pose problems for astronauts and satellites, affect polar communication networks and air traffic, as well as causing the spectacular glowing auroras, or ‘northern lights’.

Spacecraft have revealed that other planets exhibit their own spectacular plasma processes, and they have even been observed around other stars.

Dr Jonathan Nichols of the Department of Physics and Astronomy at the University of Leicester will discuss the science of space plasmas and reveal that there is, in fact, lots in space.
