Ever since Tycho Brahe suddenly died in 1601, there has been a mystery about whether the Dane whose celestial observations laid the groundwork for modern astronomy fell victim to natural causes or was murdered. On Thursday, Nov. 15, 2012 scientists who exhumed his body say one thing is clear: he was not poisoned with mercury (AP Photo/Petr David Josek, File)
