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.
The orrery was created by Fabrycky, then a postdoc at the University of California, Santa Cruz, largely due to an accident.When he created an animation of a six-planet system Kepler-11 for his work on a home computer in 2011, his son and daughter were found playing with the program.
All remaining stars were regarded as "fixed" in the background. One important discovery made at different times in different places is that the bright planet sometimes seen near the sunrise (called Phosphorus by the Greeks) and the bright planet sometimes seen near the sunset (called Hesperus by the Greeks) were actually the same planet, Venus.

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 ]
An artist's rendition of Kepler-62f, a potentially habitable exoplanet discovered using data transmitted by the Kepler space telescope. The list of exoplanets detected by the Kepler space telescope contains bodies with a wide variety of properties, with significant ranges in orbital distances, masses, radii, composition, habitability, and host star type.
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 monthly mean sunspot number in the northern solar hemisphere peaked in November 2011, while the southern hemisphere appears to have peaked in February 2014, reaching a peak monthly mean of 102. Subsequent months declined to around 70 (June 2014). [54] In October 2014, sunspot AR 12192 became the largest observed since 1990. [55]
Weather permitting, Jupiter will not only be brighter than most other stars and planets in the evening sky, but will also be visible all night long. Jupiter, ascending: See our solar system’s ...
