The supernova of 1572 is often called " Tycho's supernova ", because of the extensive work De nova et nullius aevi memoria prius visa stella (" Concerning the Star, new and never before seen in the life or memory of anyone ," published in 1573, 1602, and 1610 ) that contains both Tycho Brahe's own observations and the analysis of many other observers.
