Dr Carrie Nugent is an asteroid hunter - one of the select group of
scientists working diligently to map our cosmic neighbourhood. For
the first time ever we are reaching the point where we may be able
to prevent a natural disaster resulting from an asteroid collision.
Nugent will delve into the impact asteroids have had in the past:
the extinction of the dinosaurs, the earth-sized hole
Shoemaker-Levy 9 left in Jupiter just a few years ago, how the
surprise hit on Chelyabinsk in Russia could have started a war and
unlucky Ms Anne Hodges - the only person (that we know of) in
modern history to be the victim of a direct hit.&,nbsp,
&,nbsp, Nugent will also&,nbsp,reveal the cutting-edge work
that she is part of - using NASA's NEOWISE telescope to track down
near-Earth asteroids. NEOWISE has seen over 158,000 asteroids and
discovered over 30,000. We will also&,nbsp,get a rare glimpse
into the work of this band of asteroid hunters and their
techniques.&,nbsp,&,nbsp,&,nbsp, &,nbsp,Asteroid
orbits are chaotic which means a small early change has
a&,nbsp,big&,nbsp,impact later on. The successful hunt and
mapping of asteroids could mean nothing less than saving life on
Earth.&,nbsp,
