One of the people to view this mysterious star was the great Danish astronomer Tycho Brahe (1546-1601). Tycho (pronounced "tee-koh") noted that this new star did not change position like the planets but stayed fixed in the sky. This observation was in direct opposition to the classical Aristotelian worldview which held that the heavens were fixed and immutable - the worldview also shared by the church. Something was terribly amiss in the sky.
Tycho wrote up his and other observations of the new star in De nova et nullius aevi memoria prius visa stella usually known today simply as De nova stella, "the new star". Today we still call these types of stars "novae" and this one is now known as Tycho's star in his honor.
When yond same star that's westward from the pole
Had made his course to illume that part of heaven
Where now it burns...
