xPsi writes "Brian May, the guitarist for the legendary rock band Queen (age 60), has finally decided to submit his Ph.D. thesis in astrophysics. The title is 'Radial Velocities in the Zodiacal Dust Cloud.' From the article: 'May was studying astrophysics at Imperial College when he formed Queen with singer Freddie Mercury and drummer Roger Taylor in 1970. He dropped his doctorate research into interstellar dust as the band met with increasing success.' And, hey, if this whole Rock-n-Roll thing doesn't pan out, at least he'll have something to fall back on."
