Interesting article thanks for posting. As a Dane I have followed events related to Tycho Brahe quite closely over the years. I recall a school visit to the island of Hven and the ruins of his observatories, Uraniborg and Stjerneborg, which have now been partly restored and turned into a museum. If you are ever in the area then it's well worth a visit.
The museum has an excellent website with further information about Brahe and his life:
