Do you know what Zodiacal Dust is? Us either. But it’s apparently come back in style. Queen guitarist Brian May, who is an astronomer, began writing his thesis on the subject (something to do with, you know, stars) back in the ‘70s but was busy with the band and never had a chance to finish. Now Zodiacal Dust is a hot topic among professional stargazers and May has submitted the thesis to London’s Imperial College for review.
