Today is the birthday of the Danish astronomer Tycho Brahe. He lived from 1546 to 1601, where he died in Prague. He discovered SN1572, which we today know is a supernova, but back then he thought to have discovered a new star. For this reason he published the famous “De Stella Nova” in 1573, which was solid evidence that the night sky is changing and not a fixed background.

All his observations were made at Uraniborg on the Danish island Hven. It was given by the Danish King Frederik the 2nd and cost 1 percent of the Danish economy.
