Dr David Mannion (PhD), is an astronomer onboard the £300m Viking Jupiter – the line's newest ocean ship.
Mannion – who is a Fellow of the Royal Astronomical Society, a teacher, the head of science in an international college and an extremely enthusiastic speaker on all topics to do with astronomy – stepped away from the telescope to share what inspires him to explore the mysteries of the universe, with Telegraph Cruise.
