If you can get to Leicester anytime over the weekend of 26-27 January 2019, why not pop along to the National Space Centre? Not only is it an interesting place in its own right, but (for the fifth year in a row I think) it wil be hosting a Doctor Who packed event Science of the Time Lords.
Four Doctors and more
On Saturday you have (at the time of writing) the chance to see four different actors who have played the Doctor: Peter Davison, Colin Baker, Sylvester McCoy and Paul McGann. Sunday gives you the chance to see Louise Jameson, Katy Manning, Janet Fielding, Sarah Sutton and (more recent to our screens) Shobna Gulati.
There are also artists Chris Achilleos, Chris Thompson and Grant Perkins. Details on the website (link above).
