Jupiter III Galileo [9] [10] discovered the Galilean moons. These satellites were the first celestial objects that were confirmed to orbit an object other than the Sun or Earth. Galileo saw Io and Europa as a single point of light on 7 January 1610; they were seen as separate bodies the following night. [11] Callisto: Jupiter IV o: 8 January 1610
Linda A. Morabito (born November 21, 1953), also known as Linda Kelly, Linda Hyder, and Linda Morabito-Meyer, is the astronomer who discovered volcanic activity on Io, a moon of Jupiter. She made this finding on March 9, 1979, at NASA's Jet Propulsion Laboratory.
1979 – Voyager 1 flies by Jupiter and discovers its faint ring system, as well as volcanoes on Io, the innermost of its Galilean moons. [201] 1979 – Voyager 2 flies by Jupiter and discovers evidence of an ocean under the surface of its moon Europa. [202] 1980 – Voyager 1 flies by Saturn and takes the first images of Titan. [203]
Galileo also discovered that the Moon was cratered, that the Sun was marked with sunspots, and that Jupiter had four satellites in orbit around it. [13] Christiaan Huygens followed on from Galileo's discoveries by discovering Saturn's moon Titan and the shape of the rings of Saturn. [14]

Artist's depiction of Pioneer 10, the first spacecraft to visit Jupiter. The exploration of Jupiter has been conducted via close observations by automated spacecraft.It began with the arrival of Pioneer 10 into the Jovian system in 1973, and, as of 2024, has continued with eight further spacecraft missions in the vicinity of Jupiter and two more en route.
Just months before the launch, scientists discovered that Jupiter seemed to have a more intense magnetic field than previously thought. RELATED: NASA photos show islands before and after Hurricane ...
