The planet Jupiter, 1880.

FRANCE - MARCH 15: Colour print by Etienne Leopold Trouvelot (1827-1895), one of a set of 15, made by him whilst in the United States between 1872 and 1881. The lithographs are based on the French artist's observations from various American observatories. Titled 'The Planet Jupiter', the print shows the appearance of Jupiter on 1 November 1880. This pastel drawing shows the various cloud belts on the planet along with the prominent 'Red Spot', a feature that has persisted for hundreds of years. The sketch also shows the white silhouette of two of Jupiter's moons along with their black shadows on the face of the planet. (Photo by SSPL/Getty Images)
