The Galilean moons are named after Galileo Galilei, who observed them in either December 1609 or January 1610, and recognized them as satellites of Jupiter in March 1610; [2] they remained the only known moons of Jupiter until the discovery of the fifth largest moon of Jupiter Amalthea in 1892. [3]
Although Galileo did indeed discover Jupiter's four moons before Marius, Io, Europa, Ganymede, and Callisto are now the names of Galileo's four moons. By 1626 knowledge of the telescope had spread to China when German Jesuit and astronomer Johann Adam Schall von Bell published Yuan jing shuo, (Explanation of the Telescope) in Chinese and Latin.
Artist's concept of Galileo passing near Jupiter's small inner moon Amalthea. Although Galileo 's main mission was to explore the Galilean moons, it also captured images of four of the inner moons, Thebe, Adrastea, Amalthea, and Metis. Such images were only possible from a spacecraft; to Earth-based telescopes they were merely specks of light ...
In his book Mundus Iovialis ("The World of Jupiter"), published in 1614, Simon Marius, the court astronomer to the Margraves of Brandenburg-Ansbach, claimed to have discovered Io and the other moons of Jupiter in 1609, one week before Galileo's discovery. [7] According to Marius, he began observing the Jupiter system in late November 1609. [13]
The timeline of discovery of Solar System planets and their natural satellites charts the progress of the discovery of new bodies over history. Each object is listed in chronological order of its discovery (multiple dates occur when the moments of imaging, observation, and publication differ), identified through its various designations (including temporary and permanent schemes), and the ...
The Moon was not what was long thought to have been a translucent and perfect sphere, as Aristotle claimed, and hardly the first "planet". 1610 – Galileo Galilei observes the four main moons of Jupiter: Callisto, Europa, Ganymede, and Io; [81] sees Saturn's planetary rings (but does not recognize that they are rings), [82] and observes the ...
Europa, along with Jupiter's three other large moons, Io, Ganymede, and Callisto, was discovered by Galileo Galilei on 8 January 1610, [2] and possibly independently by Simon Marius. On 7 January, Galileo had observed Io and Europa together using a 20×-magnification refracting telescope at the University of Padua , but the low resolution could ...
In 1610, using his telescope, Galileo had discovered in that Venus, like the Moon, had a full set of phases, [44] but only in Letters on Sunspots did he commit this finding to publication. The fact that there was a full phase of Venus, (similar to a full moon) when Venus was in the same direction in the sky as the Sun meant that at a certain ...
