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 ...
Johann was the first to realize that sunspots revealed solar rotation, but he died on 19 March 1616, aged 26 and his father a year later. Several scientists such as Johannes Kepler, Simon Marius, and Michael Maestlin were aware of the Fabricius' early sunspot work, and indeed Kepler repeatedly referred to it his writings. However, like that of ...

The first sunspot drawing, John of Worcester around 1128. Sunspot drawing or sunspot sketching is the act of drawing sunspots. Sunspots are darker spots on the Sun's photosphere. Their prediction is very important for radio communication because they are strongly associated with solar activity, which can seriously damage radio equipment. [1]
The image of the sun's corona, assembled from high-resolution images taken by the orbiter's Extreme Ultraviolet Imager (EUI), shows active sunspot regions with protruding glowing plasma.
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]
SN 1604, also known as Kepler's Supernova, Kepler's Nova or Kepler's Star, was a Type Ia supernova [1] [2] that occurred in the Milky Way, in the constellation Ophiuchus. Appearing in 1604, it is the most recent supernova in the Milky Way galaxy to have been unquestionably observed by the naked eye , [ 3 ] occurring no farther than 6 ...
