Click here for my new guide to astronomical Christmas gifts


headshot_newI’m a space geek who talks to tens of thousands of people about astronomy every year, ranging from schools and the public to conferences and businesses. Also a science writer, I’ve written for The Guardian, The Observer, New Scientist, BBC Focus and European Space Agency, among many others.

The author of half a dozen books, in 2014 I was awarded runner-up in the European Astronomy Journalism Prize. Also a Fellow of the Royal Astronomical Society, I’ve talked about the wonders of the universe on Sky News, BBC News and Radio 5Live, shown Karen Gillan Saturn, helped James May navigate by the stars and taught Alan Davies the order of the planets.

My other adventures have seen me climb the biggest radio telescope in the UK, stargaze from the Sahara desert and abseil my old school’s science block for charity.

I’ve written and narrated a TED-Ed lesson on time travel which the geniuses at TED animated for me.
