Europa, the Ocean Moon
tells the story of the Galileo spacecraft probe to Jupiter`s moon, Europa.

Europa Map Images
This map of Europa was constructed primarly from Galileo spacecraft image data with a few small regions filled in with Voyager data. The scale is 20 pixels/degree at the equator for the Mercator maps.

Europa

(yr´p), in astronomy, one of the 39 known moons, or natural satellites, of Jupiter.

Europa in Color
, close in size to our Moon, is thought to have an ice surface 100 km (62 mi) thick, which overlies a silicate surface. The complex array of streaks indicates that the has been fractured.

Europa: Water World?
For decades, Mars was considered the most likely home for life in the solar system. As observations continued to show a sterile, desolate world, though, scientists began turning their attention to Europa.

Europa's atmosphere does contain oxygen but it is extremely thin so it is hard to see how it could support life. However, Europa might have oceans under its icy crust. These would be kept liquid by heat from tidal friction.

Europa is a cold smooth ice covered world. A long time ago in space there was a period of time when it was very common for asteroids, and comets to hit other worlds. This is called the Heavy Bombardment Period.

52 Europa is one of the larger asteroids. It has a diameter of 300 km, and was discovered on February 4, 1858 by Hermann Mayer Salomon Goldschmidt....

Europa. The surface of Europa is totally different from that of Ganymede and Callisto, despite the fact that the infrared spectrum of this object indicates that it, too, is covered with ice.

Europa was entranced by this beautiful yet placid creature. She adorned his horns with flowers and stroked his flanks, admiring the muscles on his neck and the folds of skin on his flanks.

Europa
One of the . Europa has an ice crust criss-crossed with dark lanes and is thought to have a liquid water mantle. The dark lanes have lengths from a few km to 1000's of km. Some are straight and others are curved.

Europa, however, seems to have it all. There are large oceans of liquid water on this Jovian moon which are perhaps ten times deeper than the oceans of the Earth. In addition, Europa also has a substantial oxygen atmospere.

EUROPA
Europa is a large, dense, icy moon of Jupiter. Europa is the smoothest object in our Solar System. Its surface is covered with long, crisscrossing trackways (but few craters) on water ice. Frozen sulfuric acid has been found on its surface.

Europa, Ganymede and Callisto are all covered in water-ice but each shows different structures indicating that each has been affected in a unique way by its history. Callisto shows the most cratering and probably shows us the oldest surface.

EUROPA
Europa is a large, dense, icy moon of Jupiter. Its surface is covered with long, crisscrossing trackways (but few craters) and frozen sulphuric acid. Its diameter is less than 2,000 miles (3,138 km), smaller than the Earth's moon.

and its shadow.
In contrast, Europa (which is 12 percent smaller than Earth's Moon) appears to have a sparsely cratered shell of water ice that may be only 10 to 250 million years old.

The orbits of Io, Europa, and Ganymede, the largest moon in the solar system, form a pattern known as a Laplace resonance; for every four orbits that Io makes around Jupiter, Europa makes exactly two orbits and Ganymede makes exactly one.

These four moons (Io, Europa, Ganymede, and Callisto) are called the Galilean satellites in his honor. In this system Galileo saw a mini-model of the heliocentric system. The moons are not moving around the Earth but are centered on Jupiter.

Europa - Europa may contain liquid water beneath its 100-mile thick ice layer, vents on the bottom of the ocean warm the ice so that 60 miles of liquid could exist beneath the ice layer, perhaps capable of supporting microbes and simple plants.

This constellation is associated with the dragon slain by Cadmus, the brother of Europa. The father sent Cadmus to find Europa who was kidnapped by Zeus. But though he searched for his sister everywhere he could not find her.

In particular, the icy moon Europa is the prime candidate for life. Many NASA scientists at JPL and other laboratories suspect with strong evidence that an ocean is hidden under the moon's solid and icy surface.

In contrast, the surface of Europa is extremely smooth. It is evidently covered by a layer of water ice that emerged from Europa's interior after the early bombardment.

0: Europa, 5.3; Ganymede, 4.6; and Callisto, 5.6. Remember that on the magnitude scale, smaller numbers represent brighter objects.

A small telescope easily picks out Jupiter's four major moons: Io, Europa, Gabymede and Callisto. All four orbit with the same hemisphere facing Jupiter -- just like our Moon orbits with the same side facing our planet Earth.

The other big ones, Io, Europa, Ganymede and Callisto, are icy and have strange markings, including "palimpsest craters," ring-like structures due to impacts which probably once created crater walls like those on our own Moon, ...

Icy Europa is crisscrossed by streaks, which close pictures suggest are flat, filled-in cracks in the crust.

In addition to the information collected about the atmosphere of Jupiter, it detected evidence of underground salt water oceans on Jupiter's moons Europa, Ganymede and Callisto, and examined the active volcanoes on the moon Io.

The story went that Zeus fell in love with Europa, the daughter of Agenor who was King of Phoenica. On one day while she was playing by the waters edge, she caught sight of a majestic white bull grazing amongst her fathers heard.

It imaged ice rafts on Europa and found that Callisto had no metallic core like the three other large moons. Galileo's also found several indications of liquid oceans beneath the surfaces of Europa, Ganymede, and Callisto.

Definition: geologic unit: A body of rock (or ice, in Europa's case) that has a distinct origin and consists of dominant, unifying features that can be easily recognized and mapped.

Geocentric As viewed or measured from the centre of the Earth.

Galilean Moons
The name given to Jupiter's four largest moons, Io, Europa, Callisto & Ganymede. They were discovered independently by Galileo Galilei and Simon Marius.

They were first discovered by Galileo Galilei in 1610, and are called the Galilean Moons: Europa, Callisto, Ganymede, and Io. Galileo discovered these moons with his newly developed telescope.

simple life exists beneath the icy crust of Europa - one of the moons
of Jupiter. Astronomers believe that there is a deep ocean beneath
the icy crust, and we know that there are simple life forms around
the deep ocean "vents" on earth.

The satellites are named Io, Europa, Ganymede, and Callisto after four of Jupiter's lovers in Greek mythology. These are the satellites that will be closely investigated during the Galileo mission a fitting tribute to the man.
