I will be conducting a series of weekly Twitter chats starting next week and running until Christmas.  Each week the chat will be based around a different popular astronomy topic.  The first will be related to The Sun Kings and will be “What level of influence does the Sun have on climate change.

Last night I was in Belgium, moderating a European debate about this important question (click here for information about the debate).  So I share what I learn with you on 24th November 6pm GMT (1pm EST, 10am PST) via Twitter.  Other chats will take place on consecutive Tuesdays in December (1st, 8th, 15th and 22nd).  Subjects could include ‘What is dark matter?’, ‘What defines a planet?’, and ‘Why isn’t Johannes Kepler better remembered?’

To take part in the chats, start following @DrStuClark and tweet your question with the hashtag #askdrstu.  Also, tweet any ideas for future topics to the same hashtag.
