Separately, centuries after German astronomer Johannes Kepler made sketches of sunspots in 1607 from his observations of the sun’s surface, the pioneering drawings helped scientists piece ...
Galileo was born in Pisa (then part of the Duchy of Florence) on 15 February 1564, [16] the first of six children of Vincenzo Galilei, a leading lutenist, composer, and music theorist, and Giulia Ammannati, the daughter of a prominent merchant, who had married two years earlier in 1562, when he was 42, and she was 24.
On his deathbed, he asked his assistant Johannes Kepler to make sense of his observations, so that it did not feel like he lived in vain. Kepler initially kept the circular orbits, and eventually found a system that would explain all the data, except for a mistake of 8 arcminutes on the position of Mars. However, Kepler trusted the accuracy of ...
Scientists analyzed famed astronomer Johannes Kepler’s 1607 sketches of sunspots to solve a mystery about the sun’s solar cycle that has persisted for centuries.
Erasmus Reinhold could have been his successor, but died prematurely. [55] The first of the great successors was Tycho Brahe [55] (though he did not think the Earth orbited the Sun), followed by Johannes Kepler, [55] who had collaborated with Tycho in Prague and benefited from Tycho's decades' worth of detailed observational data.
