565:" ("Astronomical consideration of the extraordinary and prodigious new star that appeared near the ecliptic in the sign of Sagittarius one evening in early October in the preceding year 1604, and continues to shine in the same place with a tremulous light"). The work is just over 12 pages and unfinished, which has led scholars to believe that either Maestlin failed to finish writing it or the final pages were lost over the centuries. It is estimated he wrote the treatise in April 1605, as Maestlin describes the months of February or March, when the supernova showed signs of decreasing intensity and brightness. He estimated its expiration or disappearance in May of the same year. His reasoning for this estimation came from the fact that the Sun would be in opposition with the nova at this point in time. He discusses extensively the intensity and magnitude of the nova and how it differs from the patterns seen in previous novas, such as that of 1572, which was first seen at a certain magnitude and then like others before and after it, experienced a constant decreasing throughout its visibility. The 1604 Supernova however, maintained a large magnitude for some time, as a first-magnitude star like that of Venus and the other brightest stars.

his fear that Kepler would publish their letters of correspondence, while another suggests that it was the result of a personal crisis on
Maestlin's behalf in reaction to rumors of his own suicide. Kepler, frustrated with his teacher's refusal to continue their written communication, complained to Maestlin in a letter dated 14 December 1604. He implored him to respond with his thoughts on the recently discovered and highly discussed 1604 Supernova. To not write about this event would make Maestlin guilty of the "crime of deserting astronomy," according to Kepler. Maestlin finally responded at the end of January 1605. He justified his silence by claiming that, concerning the questions Kepler had addressed to him, he had nothing more of use to add to the prior explanations. In regard to the nova, he deduced that it was in fact just a star that had previously not been discovered or noticed.
595:
the need for a new calendar was known for two hundred years, but nothing was done. He suggested that the reason that calendar was being adopted now was because the
Catholic Church lost power, and the Pope wanted "to further his dominion". This stems from Maestlin's dislike of the position of the Pope, which is shown by his statement, the Pope does not direct "the movements of the sun and moon". Maestlin believed that the Pope was trying to project power into countries that rather recently rid the Pope's powers. Then he suggested that only educated people would notice the problems with the calendar. He believed the judgment day in the year 2000, which with the Julian calendar is an inaccuracy of three days. So he does not believe the correction is worth it.

528:. Maestlin added diagrams of his views on the order of the planets and the spacing between them. This was the first time such a thing had been done. These diagrams caused a misunderstanding that lasted centuries as Maestlin did not make it clear whether the planets were supposed to be moving along the lines of the circles that were supposed to represent his planetary system, or whether they were meant to be moving within the spaces drawn by him. This led to many people believing that the planetary system suggested by Copernicus included a smaller number of modifications (such as
479:. When that comet appeared, Maestlin, along with the Danish astronomer Tycho Brahe were the first people who actively tried to calculate its path in a more complex way than simply tracking its path across the sky. Tycho Brahe and Maestlin deduced that the comet was not only travelling across the sky, but was traversing Aristotle's and Ptolemy's solid geocentric orbs, suggesting that the spheres of planets were not solid as previous astronomers believed. In 1589, he shared his conclusions about the appearance of the comet with his friend, the astrologer

After receiving his master's degree, Maestlin remained at the university as a theology student and as a tutor in the theological seminary church located in Württemberg. In letters sent to Maestlin regarding his qualifications, it was revealed that he graduated summa cum laude and ranked third in his graduating class of twenty. During the time he spent earning his master's degree, Maestlin studied under

Ptolemaic and Aristotelian models. Maestlin also concluded that the nova helped to prove the heliocentric Solar System as he said unless people concede that comets can be placed in the stellar orb, whose altitude is immense and whose extension we do not know, to which also the distance between the Sun and the Earth is incomparable, as witnessed by Copernicus.

died at the age of 37, potentially due to complications from childbirth. This untimely death left several children under
Maestlin's care and could have influenced his decision to remarry the following year. In 1589, Maestlin married Margarete Burkhardt. Maestlin and Burkhardt had eight children together. In a 1589 letter to Johannes Kepler, Maestlin recounts how the death of his month-old son, August, deeply troubled him.

While frequently in communication with Kepler between 1594 and 1600, Maestlin stopped responding to Kepler between 1600 and 1605. Kepler, eager to keep the conversation alive, wrote many letters to which he would receive no response. One theory posits that

In 1584, Maestlin was named Professor of Mathematics at Tübingen. He was elected Dean of the Arts Faculty for the following terms: 1588–89, 1594–95, 1600–01, 1607–09, 1610–11, 1615, 1623, and 1629. Maestlin taught trigonometry and astronomy. It was very likely that he used his book

In addition to his appendix, Maestlin also added his own understanding of Nicolaus Copernicus' geometry to Kepler's book, and in their correspondence they discussed such topics such as the inaccuracy of the values that Copernicus used when calculating the spheres of the cosmos.

During the days of Maestlin and Kepler, it could be considered dangerous to question God's responsibility for creating the world and all the creatures in it, because one might be accused of blasphemy. Maestlin saw things in a different light, however. He was a follower of the
