Great Red Spot studies A wider view of Jupiter and the Great Red Spot as seen from Voyager 1 in 1979 The first sighting of the GRS is often credited to Robert Hooke , who described a spot on the planet in May 1664; however, it is likely that Hooke's spot was in the wrong belt altogether (the North Equatorial Belt, versus the current location in the South Equatorial Belt). Much more convincing is Giovanni Cassini 's description of a "permanent spot" in the following year. [102] With fluctuations in visibility, Cassini's spot was observed from 1665 to 1713. [95] A minor mystery concerns a Jovian spot depicted around 1700 on a canvas by Donato Creti , which is exhibited in the Vatican . [103] [104] It is a part of a series of panels in which different (magnified) heavenly bodies serve as backdrops for various Italian scenes, the creation of all of them overseen by the astronomer Eustachio Manfredi for accuracy. Creti's painting is the first known to depict the GRS as red. No Jovian feature was officially described as red before the late

Unformatted text preview: 19th century. [104] The present GRS was first seen only after 1830 and well-studied only after a prominent apparition in 1879. A long 118-year gap separates the observations made after 1830 from its 17th-century discovery; whether the original spot dissipated and re-formed, whether it faded, or even if the observational record was simply poor are unknown. [82] The older spots had a short observational history and slower motion than that of the modern spot, which make their identity unlikely. [103] On February 25, 1979, when the Voyager 1 spacecraft was 9.2 million kilometers from Jupiter it transmitted the first detailed image of the Great Red Spot back to Earth. Cloud details as small as 160 km across were visible. The colorful, wavy cloud pattern seen to the west (left) of the GRS is the spot's wake region, where extraordinarily complex and variable cloud motions are observed...
