7 Celebrity Brainboxes. Who knew!
5. Brian May
Brian May found fame and fortune as lead guitarist of rock band Queen, but did you know that he holds a Ph.D in astrophysics from the Imperial College in London and is now a Visiting Researcher at the school? He completed most of his degree from 1970-74, when Queen began storming the international charts, but May's passion stayed with him all throughout his career, so in 2006 at age 59, the rockstar re-registered at the school and finished his degree in less than a year.
