- large, dense, icy moon of Jupiter
- the smoothest object in our Solar System
- surface is covered with long, crisscrossing trackways, but few craters
- frozen sulfuric acid has been found on its surface
- 2,000 miles/3,138 kilometers in diameter
- smaller than the Earth's moon
- 3.55 days to orbit Jupiter in a synchronous orbit
- mean distance from Jupiter is about 420,000 miles/670,900 kilometers
- mass of 4.80 * 1022 kg
- independently discovered by Galileo and S. Marius in 1610
- surface is mostly water ice
- evidence that it may be covering an ocean of water or slushy ice.
- thought to have twice as much water as does Earth
- potential for having a 'habitable zone.'
-In Jupiter's Radiation belt.
Here on Europa things are in a state of chaos. Just recently the Externovae made their way through the surface. Their colonies on the outer crust have disrupted our biocycle. We call ourselves Lochnae as the Externovae call themselves "humans". Our data retrieval team discovered that the Extranovae have decided to extend their colonization downward, into our liquid biosphere. They plan to harvest the heat generated in this subterranean ocean. They require the heat to generate power for light and warmth. For us natives however, light is unnesessary. We possess most of the same senses as the Extranovae, such as smell, touch, taste, and hearing. However, we have no eyes to see with, so we "see" our enviroment in a way similar to that of the Extranovae's sonar. We plan to take no action against the Extranovae. Soon the magnetic feilds of our planet will shift, destroying all of their electromagnetic equipment. They are not yet aware of us Lochnae, and they never will be. B-rock
