Preface Sitting with a group of friends over dinner one night in a restaurant, I raised the question, what is Europa? My normally well-informed friends were totally silent. No one had any idea of what or who Europa is. So I realized that in writing about it I had first better explain it. We live on planet Earth. Being a planet, Earth orbits (encircles) the Sun while the moon orbits the Earth. These paths are both roughly circular. Human beings have always wondered whether we are alone in the universe in that we have human life on our planet. We have also wondered whether life exists in other places in the universe. So far, at least, it doesn’t look like it. But we are searching for it. Life will exist only if there is water. …show more content…
The moon travels in an elliptical orbit around Jupiter, the largest of the planets in our solar system. Our moon circles our planet once every 28 days or so, but the moon Europa circles Jupiter once every 3.5 days. It is the most likely near-place to find life as we know it. The astronomers decided this at least on the basis of the fact that Europa has water, lots of it. More than our planet has. In fact, our astronomers have decided that Europa has a water-ice surface with oceans. That makes it an extremely likely place to find life. We have found that all living things on the Earth require water to live. This is true no matter how biologically extreme they are or how exotic. For the last twenty years, we have focused our attention upon Mars, to seek evidence of ancient bodies pf water. More recently, however, we have been focusing on a totally different direction, namely, on that of the moon, Europa. The Galileo spacecraft, in the late 1990s discovered that Jupiter’s moon, Europa, has an icy crust, and that there may be a thick layer of water hidden beneath its outer layer of ice-water. That is, there may be a very large global ocean underneath the ice. There may be several times as much water on Europa as there is on the
JUNO is a NASA mission to the planet Jupiter. The Juno spacecraft is scheduled to launch aboard an Atlas V-551 rocket from Cape Canaveral, Fla., in Aug. 2011. (www.nasa.gov). It will take 5 years to reach Jupiter, arriving in July 2016. It will orbit Jupiter 33 times. The purpose of the mission is to explore Jupiter’s structure and atmosphere. The main aim of this mission is to understand how the planet Jupiter originated and thus help us understand the evolution of the gas giants. This knowledge will also reflect upon our understanding of the origins of the Universe. The spacecraft will be placed in a polar orbit to study the planet's composition, gravity field, magnetic field, and polar magnetosphere. Juno will also search to see whether the planet has a rocky core and investigate the amount of water present within the planet’s atmosphere. NASA's Jet Propulsion Laboratory in Pasadena, CA is managing the Juno mission for Dr. Scott Bolton of Southwest Research Institute in San Antonio, Texas. The spacecraft is being built by Lockheed Martin of Denver. Scientists from 5 countries ha...
Budget cuts also threaten to push future exploration missions further away. One mission that is important is a mission to Jupiter 's moon Europa, which scientists believes hold an internal ocean that can harbor life.
Have you ever looked up into the night skies and wondered what might be out there? One question I always wonder is where in the universe might there be a livable planet? Well the answer might be closer than you think, well actually 588 million kilometers away from earth. Jupiter of course is what I’m talking about. Fell first let’s ask the why we might move. Let’s face it earth is not going to be able to be habitable forever in fact ate the rate humans are polluting the atmosphere earth won’t be around that much longer. So might need a new place to live. So could the answer be Jupiter? Before that we need to know a little about the new planet and if it’s able to sustain life. Let’s start with the Jupiter’s history. Jupiter is the largest planet in the solar system. Jupiter was named after the king of the gods and Roman mythology. The ancient Greeks named the planet after Zeus, the king of the Greek pantheon. In 1610, a man that goes by the name “Galileo Galilei” was looking through his homemade telescope when he came across Jupiter. He notice four objects circling Jupiter and described them as "four fixed stars, totally invisible by their smallness" it was there were he discovered four large moons Io, Europa, Ganymede and Callisto, which underwent several name change but are now known as the Galilean moons. This was the first time celestial bodies were seen circling an object other then Earth. Jupiter spins faster than any other planet, taking 10 hours to complete a turn on its axis, compared to that of 24 hours for Earth. This rapid spin makes Jupiter bulge at the equator and flatten at the poles, making the planet about 7 percent wider at the equator than at the poles. This is Jupiter and this is Jupiter next to the earth. Jup...
“Man masters nature not by force but by understanding. This is why science has succeeded where magic failed: because it has looked for no spell to cast over nature”. From the beginning of time man and nature has been in conflict with one another because, as a whole, there is no cooperating. Each one tirelessly wants its way. The Man is fighting for dominance and nature w never yielding its authority. In American Literature, many authors illustrate this theme in their writing. Specifically the writers Jack London in The Law Of Life, Stephen Crane The Open Boat and Mark Twain’s Huckleberry Fin. Each explores the relationship between humans and nature but with slightly different methods. Mark Twain uses nature in a realistic way, Jack London in a naturalistic way and Stephen Crane constitutes a combination of both.
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.
It is without a doubt that the most fascinating thing about space is the possibility of life elsewhere beside Earth. It is estimated that the Milky Way Galaxy itself contains about 300 billion stars. Each star contains planets and some planets might even have moons. With these findings, the question is no longer whether life exists elsewhere. The probability that Earth is the only place where life exists in the universe is far too slim. NASA has identified many planets that have similar conditions to Earth but most of these planets are hundreds of light years away so traveling there to find out if there’s any living organism is not easy. Luckily, scientific evidences have pointed out that one of the moons of Jupiter, Europa, could be one of the places where life can exist. If the theories proposed by astronomers about Europa are true, life on Europa might not even be entirely different than life near the bottom of Earth’s oceans.
I have an important proposal that will give us more knowledge about space, planets, and moons. That proposal is for a mission to the moon, Europa. I would like to send a probe there to discover the mysterious and beautiful moon. Europa is a Galilean moon that orbits the planet Jupiter. It is the Fourth smallest of all the Galilean moons. As you can guess, Galileo Galilei was the one who first discovered it. Europa is such an extraordinary moon, so there’s so many reasons why it’s interesting. One reason is that it is physically aesthetic, with a design of brown vein-like stripes covering the surface. Another reason why Europa is interesting is because it is an icy moon, with the whole entire surface covered in ice. Because of the ice, it makes
Jupiter, the largest planet in our solar system, has yet to be discovered as in depth as Juno will. NASA New Frontiers recently established the Juno Mission to observe Jupiter (Ionescu 1). The spacecraft is currently on route to Jupiter and it is set to arrive in 2016. Juno will orbit Jupiter thirty-three times total before shutting down (Ionescu 1). Juno will observe Jupiter with deeper observation than can be seen by a telescope. The Juno Spacecraft is a project made to discover Jupiter’s high winds, a possible water source, and the planetary structure.
Every day, more and more attempts of banning books and taking away the rights of our First Amendment get violated. The challenging of a book is the attempt to remove or restrict materials, and the banning is the removal of these materials. I believe that books should not be banned for these reasons.

What makes a good person good? According to WikiHow, "We should learn to define our own morals ourselves. One of the simplest ways to do so is to love others, and treat them as you would like to be treated. Try to think of others before yourself. Even doing small things daily will greatly enrich and improve your life, and the lives of others around you." This quote shows us what we need to do in order to be what society thinks as, “good". In order to be a good person, you have to do good and moral things in your society consistently. However people might think that by doing one good thing once in a while will automatically make you a “good person”, but in reality it doesn’t.
This project for Earth Science proved to be quite engaging. At first, I thought that the project was going to be long and arduous, however, being able to choose my topic for the project actually helped in galvanizing interest in it. Through this project, I learned a whole lot about the Jovian planets that fascinated me when I was a child. From gargantuan Jupiter, ringed Saturn, peculiar Uranus, and stormy Neptune, I learned many facts that I couldn’t discover outside of Earth Science. I learned many facts like how the Jovian planets got their colors, and whether or not Gas Giants are solely made of gas. I enjoy the fact that we are able to choose what we want to research about, choosing what interests us the most. Thanks to this project, I feel that I know just a bit more about the vast amount of knowledge of our Universe.
Mars is a very similar planet to earth in relation to size and atmosphere. Therefore it seemed like the most likely place to search for life. At the end of the 19th century, an American named Percival Lowell built himself an observatory so that it was possible for him to study Mars in intimate detail when its orbit was closest to Earth. At this time it had recently been suggested that the planet had a system of channels on the surface, present from the evaporation of flowing water. Looking through his telescope Lowell became convinced he could see a network of artificial canals. This led him to believe that there were intelligent beings on Mars who had built these canals. However, spacecraft have now visited Mars and found that there is no evidence of water at all. It is now thought that the lines he could see were the combination of Lowell's overactive imagination, and scratches on the lens of his telescope. We are now searching one of Jupiter's moons, Europa, as this seems to be the next likely place to hold life.
study focusing on chlorine isotopes in moon rocks, which are quite different from those found in terrestrial or outside of Earth minerals ( DNews Moon Landing Clues to Earth's Water ).
Water covers about seventy one percent of Earth’s surface. Earth is the only planet to have stable bodies of liquid water on its surface which is crucial for all known life forms. Water is a substance which acts as a solvent in which organic compounds can mix, and it is the substance which is thought to be necessary to facilitate the formation of life. There are many forms of water which include ice, liquid, and gas. Because water can exist as a gas, it can be stored in the atmosphere and be delivered as precipitate. Water also helps regulate the climat...
