Irish astrophysicist: Asteroid strike a question of when not if

The Earth is at serious risk of an asteroid strike, according to a leading Irish astrophysicist.

Prof Alan Fitzsimmons, from the Astrophysics Research Centre at Queen’s University in Belfast, has warned that an asteroid strike on the Earth is just a matter of time.

Prof Fitzsimmons has said it is a case of when an asteroid collision will happen, rather than if it will happen.
