... He made observations of a supernova (literally: nova= "new star") in 1572 (we now know that a supernova is an exploding star, not a new star). ... Brahe's meticulous observations showed that the supernova did not change positions with respect to the other stars (no parallax). ... This was early evidence against the immutable nature of the heavens, although Brahe did not interpret the absence of parallax for stars correctly, as we discuss below. Brahe made careful observations of a comet in 1577. ...
