Document Summary
Tyco brahe: suffered a tragic death where his bladder exploded due to infection after not being able to go to the bathroom in the presence of a nobleman. Lost part of his nose in a duel: known for his precision and abundance of routine astronomical observations. Discovered a nova, known today as supernovas, which are very bright stars appearing where no star had been seen before. Appeared for almost a year before disappearing, which had philosophical importance as he proved the heavens were not immutable or unchanging, which was the belief at the time. Observed a comet and deduced it was six times as far away as the moon by combining data with scientists hundreds of kilometers away and using parallax. Brahe"s work was done before the invention of the telescope, however his records were highly precise. Could not photograph his findings and thus kept detailed sketches and notes.
