Professor Brian Cox comes a close second, but seeing one of the Wonders of the Solar System up close is undoubtedly this year's highlight. For Christmas, as well as ahem, a carefully wrapped vintage globe, Mr That's Not My Age took me to see the Northern Lights. Since Joanna Lumley's trip a couple of years ago, northern Norway has seen an increase in the number of glamorous people keen to experience the aurora borealis. This is Joanna Lumley, not me. But both of us have achieved a lifelong ambition.
And fans of the pop star scientist will be pleased to hear that there's a new series to look forward to in early 2011.
Did you have a special moment in 2010?
