Unlock the secret of Queen’s lead guitarist with a surprising Ph.D. twist!

As a detective, my first step in solving this mystery was to identify the keywords of the crossword clue. The main keywords in this clue were ‘Lead guitarist of Queen‘ and ‘Ph.D. in astrophysics‘. Immediately, I realized that there was only one musician who had both these distinct qualities, and that was Brian May. But to confirm my suspicions, I dug deeper and conducted some research on him. I found that besides being one of the greatest guitarists of all time, Brian May possesses a Ph.D. in astrophysics from Imperial College London. His thesis was on the topic of the motions of interplanetary dust, which he earned in 2007. All of these clues and insights finally led me to the solution of the crossword clue: BRIANMAY – the remarkable lead guitarist of Queen who holds a Ph.D. in astrophysics.
