EUROPA AND TITAN; LIFE IN OUR SOLAR SYSTEM
.............................................
Wouldn't it be amazing if we woke up one morning and realized that there were aliens in our inter-steller backyard? That could possibly be true if there were life on the moons Europa and Titan. Europa is one of Jupiter's moons. It is the sixth closest moon to the gas giant. It is one of the moons Galileo noticed when observing Jupiter. Though it was the least bright then, it is really the sixth largest moons in our solar system. Europa is made of silicon like rock and probably has an iron ore. It has an atmosphere composed of mainly oxygen and its water and ice surface is streaked with cracks and lines. Due to it's smooth surface and youth, this planet could have a large ocean underneath the surface. This ocean could hold life. Most of the information from Europa comes from the 1989 satellite Galileo. Other observations of the planet have come only by fly-bys. The next mission to this moon will come from JUICE a European Space Agency craft due to launch in 2022. Titan is a moon of Saturn. It is the largest moon of the beautiful planet. It has a thick dense atmosphere (the only natural satellite to have one) and surface water (the only water in the solar system besides Earth). It is the second largest planet in the solar system, and it's volume is bigger than that of Mercury. Titan is composed of mainly ice and rock. It's dense atmosphere has presented past telescopes to see the surface. In 2004, Cassini detected hydrocarbon lakes on the surface. It has a climate that produces physical features, and has a methane cycle similar to our water cycle. It could be the home to methane reliant aliens. --The Brain
