One of Jupiter’s moons.

1610        Jan 7, The astronomer Galileo Galilei sighted four of Jupiter's moons. Galileo discovered the 1st 3 Jupiter satellites, Io, Europa & Ganymede. He discovered mountains and valleys on the moon, that Jupiter has a moon of its own, and that the sun has spots which change. Galileo discovered multiple moons around Jupiter. He also observed Mars.

1996        Jun 27, New Galileo pictures from 96,000 miles gave hints that fractured crusty icy slabs, 50-60 miles thick, might be sliding on a layer of slush or water.

1997        Apr 9, New images of Jupiter’s moon Europa revealed a surface of massive icebergs floating on an ocean more than 50 miles deep.

1997        Dec 16, The Galileo spacecraft flew to within 124 miles of the surface and recorded images of Europa. Volcanic ice flows implicated a vast ocean below the surface. Metallic cores inside Io, Ganymede and Europa and the lack of a similar core inside Callisto was also indicated.

1998        Dec 8, It was reported that a mysterious fault stretched at least 500 miles across the ice surface of Europa.
    (SFC, 12/8/98, p.A5)

2000        Jan 3, The Galileo space probe recorded Europa's magnetic field during a flyby and found that the magnetic north pole reversed about every 5 1/2 hours. An underground conductive liquid was suspected to cause the flip flop.
    (SFC, 1/11/00, p.A4)

2002        May 25, It was reported that the ice of Europa is at least 12 miles thick.
