Such discoveries are often a multi-step, multi-person process. Multiple discovery sometimes occurs when multiple research groups discover the same phenomenon at about the same time, and scientific priority is often disputed. The listings below include some of the most significant people and ideas by date of publication or experiment.

Named after the Italian astronomer Galileo Galilei, the Galileo spacecraft consisted of an orbiter and an atmospheric entry probe. It was delivered into Earth orbit on October 18, 1989, by Space Shuttle Atlantis on the STS-34 mission, and arrived at Jupiter on December 7, 1995, after gravity assist flybys of Venus and Earth , and became the ...
Galileo Galilei, early proponent of the modern scientific worldview and method (1564–1642) The Italian mathematician, astronomer, and physicist Galileo Galilei (1564–1642) was a supporter of Copernicanism who made numerous astronomical discoveries, carried out empirical experiments and improved the telescope.
The discoveries of Io and the other Galilean satellites of Jupiter were published in Galileo's Sidereus Nuncius in March 1610. [1] While the Jovian moons he discovered would later be known as the Galilean satellites, after himself, he proposed the name Medicea Sidera (Medicean Stars) after his new patrons, the de'Medici family of his native ...
The discoveries of Kepler and Galileo gave the theory credibility. Kepler was an astronomer who is best known for his laws of planetary motion , and Kepler´s books Astronomia nova , Harmonice Mundi , and Epitome Astronomiae Copernicanae influenced among others Isaac Newton , providing one of the foundations for his theory of universal ...
Scheiner argued that what appeared to be spots on the Sun were in fact clusters of small moons, thereby trying to deploy one of Galileo's own discoveries as an argument for the Aristotelian model. [ 40 ] [ 41 ] In his Letters on Sunspots Galileo showed how sunspots were nothing like the moons of Jupiter, and the comparison was false.
