Europe

Do not get confused. The topic relates to Europe the satellite, not the continent.

Before starting out talking about this curious satellite, let's say that I've been going over wikipedia again, and I've found quite a few articles talking about the universe. How I came to this I don't know, but it is probably due to my everlasting curiosity of learning new things. Yep, wisdom is based on knowledge and how you interpret it. No info -> No knowledge -> No wisdom... :D Besides, It's been the 40th century since the first time man landed on the Moon.

Europe is one of the four main satellites of Jupiter. It is also the most interesting at a scientific level. It is approximattely the same size of our beloved moon, but a bit more colourful, and not as dusty. :D Europe's atmosphera is a weak layer composed by oxygen (100%), but this is not a biological oxygen (which means no plant or biological being has created it). The underlying theory about it says the oxygen is freed due to a surface's reaction to the sun beams. The magnetic field is quite weak in comparison to other planets, however it is rather influenced by the field generated by its father (Jupiter) which is one of the strongest ones in the Solar System. Moreover, sciencists speculates that Europe's core is made up of iron.

Here comes the interesting thing: Europe's surface is not made of earth or silicates as the Earth's is, on the contrary it is made of water, and this layer of water is 90 km deep, which totally forms the crust of the satellite. The surface is frozen due to the low temperatures outside (-170º) and it keeps a salty ocean underneath it, which is likewise warmed by the core activity.

Let's say this water rallies all the conditions to hold life in it, and real beings live within. Wow! That would mean we are not alone in the universe, and there's something else out there. Of course we must think in lifeforms like bacteria or microorganisms. I wont bet my ass there are carnivorous monsters twice the size of a human swimming and killing each other under that thick layer of ice... That would be awesome though, wouldn't it?
