Jupiter´s Europa Moon

Questions like how life exists beyond our solar system or under Jupiter’s icy crust have been theorized as the discoveries of Jupiter continue. According to the article, water vapor has observed on one of Jupiter’s moon, Europa. A probe called “Juice” will be launched in 2022 to study Jupiter and its moons, Europa, Ganymede, and Callisto. The mission would also determine if there are oceans on Jupiter, including how deep they are. However, there are some challenges Juice will have to face such as the ability to generate enough energy, the materials it is made out of that would have to withstand the forces of deceleration, and to shield itself from the intense magnetic field around Jupiter. Therefore, when Juice is completely built and launched,

On Earth we have one moon to look at during the night. Can you imagine looking at 50 or 60 moons at night? If we lived on Jupiter, that’s what we would see! Jupiter has 50 definite moons. There are 17 moons scientists are still examining to make sure that they are moons. Some are smaller than 1.5 miles in diameter! Jupiter’s four largest moons, and four first discovered, are known as the Galilean moons, named after their discoverer Galileo Galilee in 1610.

Jupiter is the largest planet in the solar system. Fittingly, it was named after the king of the gods in Roman mythology. The distance from the Sun to Jupiter is approximately 779 million km, or 484 million miles. The exact number is 778,547,200 km. The most obvious features on Jupiter are the alternating bands of white and colored clouds, zones and belts. Analysis of data at many wavelengths shows that the white regions have higher thicker, clouds than the redder regions.

Galileo spacecraft first discovered the four largest moon of Jupiter, called Io, Europa, Ganymede and Ganymede and Callisto. Ganymede is the largest moon in the Solar System Atmosphere And Planetary Composition: Temperature Range: The cloud-tops average 120 K=153*C=-244*F. Atmosphere: Jupiter is a gaseous planet; it does not have a solid surface like the Earth does (but probably has a solid, rocky core 10 to 15 times the mass of the Earth). When we look at Jupiter, we are seeing icy clouds of gases moving at high speeds in the atmosphere. Jupiter's atmosphere is composed of about 90% hydrogen and 10% helium.

Since Europa is Jupiter’s moon, it is orbiting Jupiter. Europa is made out of silicate rock and is grooved out with cracks and streaks. The crust of this moon is frozen which is covered in ice. The density is 3.01 g/cm3 which would

In Orson Scott card’s book, Ender's’ game, The novel takes place in a futuristic world where aliens attempted to take over the earth and a young boy named Ender is chosen to lead earth's army to victory. So far mars has been the most significant candidate for extraterrestrial life in our solar system. For a planet to have a suitable environment for life it must have liquid water, oxygen, carbon, atmosphere, heat/warmth, nutrients/food. One of the four moons that orbited Jupiter named Europa was recently expected to have the essentials for life. The moon Europa has strong tidal heat which could keep water in liquid form beneath its layer of ice. Although life on Europa is a small chance there's is one more option which is the largest moon that

Ganymede is similar to Europa in that its surface is made of mainly ice, but it does have bits of rock here and there. Also like Europa, Ganymede is believed to have an ocean below its surface. The core is made of metallic iron while its middle layer is made of rock. In 1996, scientists discovered that Ganymede has a very thin oxygen atmosphere, but it is not thick enough to support life. With a surface temperature of -163 degrees Celsius, it would be a harsh environment to live in.

Galileo started off the mission by launching off on October 18th, 1989 at Kennedy Space Center, Florida. The spacecraft entered Jupiter’s orbit on December 8, 1995. Its mission ended and it decayed into the atmosphere on September 21, 2003. Galileo also discovered various meaningful results such as certain measurements in the atmosphere. For example, the density and temperature of the upper atmosphere is greatly higher than expected. On the other hand, the lower atmosphere’s temperature is closer to what was expected. Additionally, it was analyzed that the deep atmosphere was dryer than expected. Furthermore, it was discovered that the scientific instruments on the spacecraft worked successfully. While on the mission, Galileo detected a radiation belt between Jupiter’s ring and upper atmospheric layers. It is believed that Jupiter’s radiation belt is 10 times stronger than Van Allen, which is the radiation belt near Earth. Galileo also studied the winds on Jupiter. It found out that the winds are strong alternating east-west jetstreams, which is dissimilar to Earth’s wind system. The winds on Jupiter below the clouds are 540km/hr (330mph). On Galileo’s mission, there were many important firsts. Galileo had a close flyby of an asteroid, Gaspra. Galileo also discovered a satellite of an asteroid. The satellite was named Dactyl and the asteroid was Ida. Galileo was also the first atmospheric probe to enter Jupiter's atmosphere. The spacecraft was also the first to enter Jupiter’s orbit and go around it. Galileo also directly observed a comet impacting a planet. The comet was Shoemaker-Levy 9. But by far, the most important discovery was discovering liquid ocean water under Europa’s (one of Jupiter’s moons)

Jupiter is the god of all gods. He had so much power he gave his brothers powers. Jupiter was the most powerful thing in the world. He had two brothers, a dad that he overthrew, a wife, and a daughter.

Io is the innermost of the four Galilean moons of Jupiter. It is the third largest moon of Jupiter out of the 67 known moons. Io is the most geologically active object in our solar system with over 400 active volcanoes. Because of the activity of volcanoes Io's atmosphere is mostly made up of sulphur dioxide (SO2). As Io intersects Jupiter's orbits, Jupiter's magnetic field converts Io into an electric generator, as the massive planet rotates a ton of Io's material is stripped away. But, this does not affect the moon, because of the heavy activity of volcanoes the molten lava which is spewed all over the planet cools and becomes a solid. Craters in the planet are filled and soon become lava lakes before becoming a solid once again. Io surface

By observation, it is known that Europa has an icy surface. It is furthermore likely that Europa would have a cold surface as a result of its distance from the Sun. The icy surface contrasts heavily with the possibility of the hot core that Europa may have. According to Elizabeth Howell, a

One of Saturn’s moon, Titan, possess planetary conditions unique to the solar system. It has an incredibly thick and organically rich atmosphere and a vast number of different liquid conditions. The numerous ways in which its atmosphere and liquids interact results in the formation of a vast array of different organic and prebiotic molecules, making it an excellent location for the possible development of life, despite its frigid temperatures. Understanding how life could form on Titan would give insight regarding not only how life formed on Earth, but also to how, what ways, and what forms life could form on other planets with conditions dissimilar from Earth, opening up the number of planets that could be seen as hospitable to life, as well as possibly expanding the search for life to icy moons. Titan’s atmosphere and liquid conditions, surface and subsurface, its primordial conditions, as well as Titan’s frigid subzero temperatures, all place limitations on and give new opportunities to the formation of life in ways that resemble Earth’s life, but more frequently in ways entirely different, in chemical composition, general structure, and metabolism. However, in some ways, Titan’s conditions may be too unstable and harsh for the development and survival of life.

Besides Earth, the Titan Moon is known to have large areas of liquid on its surface. The Titan Moon surface

Jupiter is the fifth planet from the Sun and by far the largest mass object in the solar system of all the other planets. Jupiter is twice the size of all the other planets combined. It is as 318 times the sizes of earth. The distance that Jupiter orbits the sun is 778,330,000 km (Gallant pp154). The diameter is 142,984 km and the mass that it has is 1.900e27 kg. Jupiter is the fourth brightest object in the sky after the Sun, the Moon and Venus. Mars is some times brighter. Galileo discovered Jupiter in 1610(Gallant); another interesting fact is that Jupiter has 4 large moons. Which are known as the Galilean moons. They were named Io, Europa, Ganymede and Callisto. The first mission that went to Jupiter was Pioneer 10 in 1973 and later

Right alongside the fifth and largest planet in our solar system, Jupiter, orbits a moon only about the same size as Earth’s moon. On this moon, is an icy surface that scientists are trying to uncover. Due to the presence of what they believe to be water, there is the possibility of life on this moon named Europa.
