Neither. Both have been visible since anyone looked up in the night sky.
So neither of them were discovered.
Europa is one of Jupiters moons. Jupiter has many moons, but Europa is one of the four large moons that was discovered in 1610 by Galileo Galilei (and possibly independently by Simon Marius around the same time).
Hans Lippershey invented the telescope, but Galileo Galilei improved it for astronamy. Galileo was the one who discovered four moons of Jupiter, The names of the moons are Io, Europa, Callisto and Ganymede. Although Jupiter has over 60 moons those are the first 4 identified because hey are the largest.
Jupiter has 67 known moons, although 17 of them are awaiting official names. More are discovered with every space probe we send there. It is likely that there are more not yet identified. The most recent are extremely small. As with the icy moonlets in Saturn's rings, there are millions of small objects orbiting the planet, some as part of Jupiter's own rings.63 moonsJupiter has 63 known moons. But 4 main moons, the largest of the 63.
Some older science textbooks used to state that Jupiter had 16 moons, but several recent space probes have discovered a few dozen more. Jupiter is now known to have 63 moons, and more are almost certain to be discovered. Earth, on the other hand, has just the one Moon.
Yes, the first planet from the sun, Mercury, does not have any moons. It is one of the two planets in our solar system that do not have any natural satellites.
For being one of Jupiters famous moons. TAMJA!
Yes he did! Galileo was the first one to discover Jupiter's 4 moons.
Yes, there is water on one, and volcanoes active on another.

Cold, icy (perhaps liquid ocean because of tidal forces of Jupiter), and it is one of Jupiters moons.
they did found water on mars. and one of jupiters moons maybe.

Pandora is one of Saturn's moons, discovered in 1980 by the Voyager 1 space probe. Its quite small and is one of the inner moons of Saturn.

Phoebe, which is one of Saturn's moons was discovered by William Henry Pickering in 1899.
Neptune actually has 14 known moons, as another one was discovered in 2013.
Europa is one of Jupiter's moons and is believed to have a subsurface ocean beneath its icy crust. This moon is of interest to scientists because it may have conditions favorable for life due to the presence of water and a possible heat source from volcanic activity.
