Research by astro-physicists from Exeter University features in the BBC programme The Sky At Night, this evening.
Post-graduate student Hannah Wakeford will be shown talking about planets which orbit other stars, known as exo-planets.
The programme focuses on the progress in exo-planet research, and whether any of these planets could harbour life.
