In Terry Gross‘s interview, Brian May, guitarist of Queen, put on an unexpected (by me) hat, and explained that everything in the universe is made of the dust of supernovae. He noted that Joni Mitchell was therefore accurate when she wrote, “we are stardust…” in Woodstock.
May, it turns out, studied the dust streaming through our solar system for his PhD, which he went back for after Queen and obtained in 2007. According to Wikipedia, he is currently the Chancellor of Liverpool John Moores University.
