For more than 10 years, NASA (www.nasa.gov) scientists have pondered that Europa’s strange dark lines could result from, and now it has been discovered that they could be sea salt in an ocean below the surface of this moon of Jupiter that was discolored due to radiation exposure.
The discovery of sea salt is considered to be a scientific adventure in the search for life on other worlds, since it may mean that Europa’s sea is interrelated to its surface, which could be a factor in whether or not there is life on the moon of Jupiter.
Radiation May Have Helped Create Strange Dark Lines of Europa
The research is being done by NASA scientists at the Jet Propulsion Laboratory (www.jpl.nasa.gov) in Pasadena, California. They already knew that Europa was being radiated due to the strong magnetic fields of Jupiter and they now believe the radiation could be part of what is forming the strange dark lines on Europa’s surface.

Sulfur could still be part of some of the various colors of the strange dark lines, say researchers, but only for the areas that are the youngest.
The new experiment involved chilling sodium chloride samples down to -279 Fahrenheit, or -173 Celsius, and then saturating them with electrons to create an atmosphere similar to the conditions on Europa’s surface. When they did this, the salt turned from white to a yellow-brown color, which is the same color as the strange dark lines of Europa. According to the scientists, this showed that it was a close match to the data on the strange dark lines that NASA has from their spacecraft
Sulfur goes back to the ancient times but it was called brimstone. In 1979, a French chemist named Antoine Lavoisier recognized sulfur was an element and added it to his list of elements. The element sulfur is considered a nonmetal and is the 10th most abundant element in the universe. On the periodic table sulfur is in group sixteen and it is a representative element. Sulfur has an atomic mass of 32.07 with an atomic number of 16. There are three energy levels for sulfur the first energy level is two, the second energy level is eight, and the third energy level is six.
In 1977, a recent research by geochemists Eoghan Reeves, Jeff Seewald, and Jill McDermott at Woods Hole Oceanographic Institution (WHOI) is the first to test a fundamental assumption of this ‘metabolism first’ hypothesis. This popular view says simple reaction emerged near ancient seafloor hot springs. These reactions presumably turned a nonliving world to a living one.
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...
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...
thought that Pluto belonged there (Dwarf Planets) and it would more interesting to study it in that way. For instance,
During the period from 1985 through 1990, Earth was aligned with the orbit of Charon around Pluto such that an eclipse could be observed every Pluto day. This provided opportunity to collect significant data which led to albedo maps defining surface reflectivity, and to the first accurate determination of the sizes of Pluto and Charon, including all the numbers that could be calculated therefrom.
Salt is made up of sodium and chlorine and it is a natural occurrence on our planet, it can be found and harvested mainly from the seas, oceans or salt lakes. However salt can also be mined from within the earth from dried up underground seas, normally it’s only used as road salt (maldonsalt). The product salt has multiple functions, Salt is used to preserve foods and also to flavor foods, salt can also be used as a stabilizer in water and rock salt is used to melt ice during the winter (Freeman, 2007).
Doctor Robert Harry Tyler is a Research Scientist at Goddard Science flight Center in Maryland, USA. Dr.Tyler works under Maryland University and NASA to study the oceans in other planets and theorise how they work in ways just like our own oceans. Also how they do not freeze from the subzero temperatures of space. Dr. Tyler has many theories on how they many work one theory is that there is radioactive rock within the planet that is creating heat to keep the ocean from freezing. There is another way by the gravity of the neighboring moon or planet.

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.
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...
