Researchers at Aarhus University
in Denmark have put to bed once and for all the rumors of Tycho Brahe's murder by mercury poisoning
that have swirled for more than four hundred years, and all it took was exhuming the long interred corpse of the Danish astronomer from it's rightful resting place. Researchers have also found that Brahe's prosthetic nose, rumored to be cast from gold or silver, was actually made of brass,
presumably solving this last mystery because, hey, if you've already got the guy dug up and all, why not, right?
