I'll be online at 3pm on Friday 3rd June, live from the Hay Literary Festival answering your questions. Feel free to ask anything you like, be it about astronomy or writing or combining the two. Please submit your questions in advance to the Hay Festival Q&A website. That page will also be the place to follow the interview, or catch up on it after it has finished.
Do check out the other authors performing their own Q&As, there are some fascinating people participating.
My thanks to Siobhan Maguire for making this happen. Also a big thank you to everyone who is coming along to my talk at 1pm that day. You've made it a sell out and I can't tell you how appreciative I am!
P.S. 4 June 2011, the Q & A was great fun and if you look at Hay Festival Q&A website you'll see all the questions you sent in, thank you, and my answers.
