I have extensive media experience, I talked on BBC radio for the first time in 1989 during my PhD. Since then I have talked on radio over one hundred times, and have also appeared on TV, including several live interviews. In the U.S. I have appeared on CBS, ABC, C-SPAN and NPR, and in the U.K. on the BBC, ITV and S4C. Recently I contributed to a TV series called "The Cosmos", an eight-part TV series; I appeared in most of the episodes.
Here is an interview with me on live TV where I am talking about the 2012 Transit of Venus.
Here is a video of me talking about the establishment of a dark-sky "discovery centre" at the Wales National Botanical Gardens.

I have been lecturing for over 20 years. In recent years I have been invited by various cruise lines to lecture on cruises. The topics of my talks vary, but usually include an introductory talk where I let the guests know what will be visible in the night-time sky during the cruise. So far I have given talks on cruises in Europe, South America, the Pacific (Hawaii and French Polynesia), and Asia. I am about to go on a cruise to New Zealand, a 14-night cruise which leaves Brisbane and sails around both the north and south island of New Zealand.
