Danish astronomer Tycho Brahe's body exhumed in Prague
The body of pioneering 16th Century astronomer Tycho Brahe will be exhumed to try to confirm the cause of his death.
He was thought to have died of a bladder infection, but a previous exhumation found traces of mercury in his hair.
Professor Jens Vellev, from Aarhus University, is leading the team of scientists and archaeologists.
