Abstract

As a region where liquid water may exist on the surface of rocky planets, and a place where we know life can exist, the habitable zones of other Sun-like stars are naturally a place of interest. One way to study the environment in which Earth analogues reside is via the dust liberated from asteroids, comets, and planets - the so-called "exo-Zodi". This dust reveals processes that may be similar to those that have occurred throughout the Solar System's history, but is also a potential source of noise for the future imaging and characterisation of Earth analogues. I
will outline some of the Solar System's history near the Earth, discuss observations of warm dust around other stars and possible scenarios and implications, and end with a brief look to upcoming observations with the Large Binocular Telescope Interferometer.
