Tyge – Tycho in latin – Ottesen Brahe (1546-1601) was a Danish astronomer and founder of modern astronomy. Tycho Brahe’s biggest goal became to survey the solar system.

Tycho Brahe was about 27 years old when he observed the constellation of Cassiopeia, a new and highly luminous star, in the Milky Way. The observation was done at a time where the stars' positions were known to be stationary, which made the observation quite surprising. 

The new star turned out to be a supernova, which refers to a star positioned 7.500 light years from earth. From his discovery, Tycho Brahe could establish the fact that the comets were positioned further out in outer space than the moon.

Tycho Brahe disposed of the belief that stars were stationary in his book De Nova Stella – "On the New Star" - from 1573.

Brahe died in Prague in 1601. He moved to the city after losing the Danish support of his work, which happened with the death of King Frederik II.

Tycho Brahe’s cause of death is not known with certainty. It is reported that he died of mercury poisoning or because of a bladder rapture, but both are regarded as untrue.
