Astronomy Outreach

Welcome to the Exeter Observatory, run as a private observatory in Matford, Exeter, UK.

I am available to give talks to societies, organisations, academic institutions and companies.

I am an experienced cruise ship lecturer and have been guest speaker on major cruise lines including Cunard, Viking and P&O. See my profile at

Cruise Ship Profile

John Maclean FRAS


“I had the distinct pleasure of being a fellow guest speaker with John Maclean on a recent cruise aboard Cunard’s Queen Victoria.  As a NASA retiree and an astronomer wannabe, I found Johns lectures to be most interesting, informative and inspirational.  He is a gifted lecturer who has the innate ability to make the complexities of our universe understandable to all.  John speaks with authority and knowledge and makes learning about astrophysics downright “Fun”.  
Tangible proof of John’s ability to inspire the next generation of explorer was demonstrated by Joanne, a young lady in his audience.  Joanne informed me that John’s lectures motivated her to go back to college to pursue a degree in Astronomy…the realization of a lifetime dream.”

I am an agent for the important NEOShield-2 asteroid deflection project! Do I get a badge and a secret weapon, I wonder?

I am also UK Ambassador for the NASA OSIRIS-REx Asteroid Sample Return Mission and can deliver talks about the mission for your organisation.

OSIRIS-REx seeks answers to the questions that are central to the human experience: Where did we come from? What is our destiny? Asteroids, the leftover debris from the solar system formation process, can answer these questions and teach us about the history of the sun and planets.

The OSIRIS-REx spacecraft is traveling to Bennu, a carbonaceous asteroid whose regolith may record the earliest history of our solar system. Bennu may contain the molecular precursors to the origin of life and the Earth’s oceans. Bennu is also one of the most potentially hazardous asteroids, as it has a relatively high probability of impacting the Earth late in the 22nd century. OSIRIS-REx will determine Bennu’s physical and chemical properties, which will be critical to know in the event of an impact mitigation mission. Finally, asteroids like Bennu contain natural resources such as water, organics, and precious metals. In the future, these asteroids may one day fuel the exploration of the solar system by robotic and manned spacecraft.
