Brian May, the multimillionaire guitarist who founded the rock group Queen, has finally completed the PhD in astrophysics that he abandoned more than 30 years ago.
The 59-year-old composer of hits such as Fat Bottomed Girls and We Will Rock You turned his back on the stars for international fame with Freddie Mercury and his band. His thesis on interplanetary dust clouds lay gathering dust of its own in the attic of his home in Surrey.
May's interest in the subject was rekindled last year when he co-authored a children's science book with the astronomer Sir Patrick Moore. He discovered that remarkably little research had been done in the intervening 33 years.
