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

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.

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