Lecture to reveal comet’s secrets

Some of the secrets of the solar system will be unveiled at a public lecture next week by a planetary scientist from Imperial College in London.

Matthew Genge, an expert on extra-terrestrial dust and one of a number of scientists studying samples collected by a Nasa probe sent to a distant comet, will be speaking at Trinity College in Dublin on Monday.

The scientists are investigating the theory that comets may have provided our planet with some of the water and organic material that allowed life to develop on Earth.
