11 de abr. de 2024 · Johannes Kepler, German astronomer who discovered three major laws of planetary motion. His discoveries turned Nicolaus Copernicus’s Sun-centered system into a dynamic universe, with the Sun actively pushing the planets around in noncircular orbits.

Johannes was born prematurely on 27 December 1571, in the Free Imperial City of Weil der Stadt (now part of the Stuttgart Region in the German state of Baden-Württemberg, 30 km west of Stuttgart’s center). As a child, Johannes Kepler also suffered from smallpox. The disease left with crippled hands and a weak vision. This limited his ability to foc...
Johannes was introduced to astronomy at an early age and developed a strong passion for it that would span his entire life. His mother introduced him to astronomy, who took him out at night to show him interesting things in the skies, including the Great Comet of 1577, writing that he “was taken by [his] mother to a high place to look at it.” In 15...
Kepler’s mother, Katharina Guldenmann, was a healer and herbalist who was considered to be a witch. At one point, Kepler had to hire lawyers to defend his mother from being sentenced to death. The story goes, a certain Ursula Reingold claimed that Kepler’s mother Katharina had made her sick with an evil brew. The dispute escalated, reaching the tow...
It was not only Katharina Guldenmann, Kepler’s mother, who was accused of witchcraft, but also other female relatives of his. For instance, during Katherine’s trail it was claimed that Katherine had been instructed in magic by an aunt, who had in fact been burned for sorcery. Kepler’s own grandmother was tried in the Salem Witch Trials and sentence...
Kepler’s remarkable scientific career had a humble start, as he started out as a math teacher in a seminary in the Austrian city of Graz. Despite his desire to become a minister, near the end of his studies at Tübingen, Kepler accepted an offer to teach mathematics and astronomy, in April 1594, as a replacement to Georg Stadius at the Protestant sc...
Kepler had a tumultuous relationship with Danish astronomer Tycho Brahe; but it was the accurate planetary data of Brahe that enabled Kepler to make his great discoveries in astronomy. Tycho Brahe was a Danish astronomer, known for his accurate and comprehensive astronomical observations. Kepler become Tycho’sassistant in about 1600. The two had di...
Kepler incorporated religious arguments and reasoning into his work, motivated by the religious conviction and belief that God had created the world according to an intelligible plan that is accessible through the natural light of reason. He regarded his three laws of planetary motion as celestial harmonies that reflected God’s design for the unive...
Apart from his laws of planetary motion, Kepler made important contributions to optics, including formulation of the inverse-square law governing the intensity of light. Kepler was able to invented his own version of the refracting telescope, which helped him understand the structure and working of the eye.
William Borucki at NASA’s Ames Research Center begins researching the potential of finding Earth-size planets beyond our solar system by searching for the slight dips in starlight as a planet crosses in front of its star — a technique called “transit photometry.” After four rejections by NASA, in 2001 the Kepler space telescope mission is at last a...
Johannes Kepler passed away on November 15th, 1630 in Regensburg after suffering with fever. He was buried at the local cemetery. Unfortunately, the exact location of Kepler’s grave was lost for good during the Thirty Years’ War between Germany and Sweden after the Swedish army destroyed the churchyard.

Kepler Discovers the Truth about Planets’ Orbits. Kepler thought Copernicus’s heliocentric view of the solar system was right. His own belief, one which would transform science, was that the sun exerted a force on the planets orbiting it. In 1596, at age 25, he published a book – Mystery of the Cosmos.
