Dr Lewis Dartnell, a UK Space Agency research fellow at the Department of Physics and Astronomy, is no stranger to discussing the likelihood of alien life existing, having previously researched whether or not we are alone in the universe.

In an interview hosted by BT, Dr Dartnell discusses how feasible the existence of certain alien lifeforms from science fiction is, looking at the science behind the species and concluding whether or not they could truly exist under the right conditions.

While he suggests that some such as humanoid aliens, giant invertebrates and robotic automatons could be plausible, others, such as gas-based lifeforms or creatures from another dimension seem highly unlikely.

Perhaps one day mankind will have a close encounter of the third kind with one of the above lifeforms, although it seems unlikely they would appear as they do in the likes of Dr Who and Star Wars.
