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.
Johannes Kepler observed a sunspot in 1607 but, like some earlier observers, believed he was watching the transit of Mercury. [11] The sunspot activity of December 1610 was the first to be observed using the newly invented telescope , by Thomas Harriot , who sketched what he saw but did not publish it. [ 12 ]
The earliest surviving record of deliberate sunspot observation dates from 364 BC, based on comments by Chinese astronomer Gan De in a star catalogue. [8] By 28 BC, Chinese astronomers were regularly recording sunspot observations in official imperial records. [9] A large sunspot was observed at the time of Charlemagne's death in AD 813. [10]
Johannes Kepler's first major astronomical work, Mysterium Cosmographicum (The Cosmographic Mystery), was the second published defence of the Copernican system.Kepler claimed to have had an epiphany on July 19, 1595, while teaching in Graz, demonstrating the periodic conjunction of Saturn and Jupiter in the zodiac: he realized that regular polygons bound one inscribed and one circumscribed ...

NASA's Kepler Space Telescope has been hard at work scanning the universe for planetary bodies and has now confirmed a whopping 104 of them outside our solar system as part of its K2 mission.
Kepler introduced the idea that the physical laws determining the motion of planets around the Sun were the same governing the motion of moons around planets. He justified this claim in Book IV using the telescope observations of the moons of Jupiter made by Simon Marius in his 1614 book Mundus Iovialis .
About a year ago, the discovery of a star's odd, intermittent dimming prompted a number of explanatory theories -- including alien activity. Mystery surrounding dimming star deepens following new ...
