... 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. ...

... The software was originally developed as a set of Fortran routines which were available both as stand-alone executables and as IRAF tasks in the Dither package. ... This set of code formed the basis for a more automated task for aligning images to produce distortion-corrected images; namely, the Python task PyDrizzle (Section 5.3) . Finally, all the steps required to identify cosmic rays using the aligned images produced by PyDrizzle were automated in the Python task MultiDrizzle (Section 5.4) . ...
