Galileo made numerous orbits around Jupiter visiting at close distance most of the moons. This brought us a lot of superb photographs.\n\nA lot of info can be found here:\nhttp://galileo.jpl.nasa.gov/

Jupiter is the fifth planet from the Sun and is the largest one in the solar system. If Jupiter were hollow, more than one thousand Earths could fit inside. It also contains more matter than all of the other planets combined. It has a mass of 1.9 x 1027 kg and is 142,800 kilometers (88,736 miles) across the equator. Jupiter possesses 28 known satellites, four of which - Callisto, Europa, Ganymede and Io - were observed by Galileo as long ago as 1610. Another 12 satellites have been recently discovered and given provisional designators until they are officially confirmed and named. There is a ring system, but it is very faint and is totally invisible from the Earth. (The rings were discovered in 1979 by Voyager 1.) The atmosphere is very deep, perhaps comprising the whole planet, and is somewhat like the Sun. It is composed mainly of hydrogen and helium, with small amounts of methane, ammonia, water vapor and other compounds. At great depths within Jupiter, the pressure is so great that the hydrogen atoms are broken up and the electrons are freed so that the resulting atoms consist of bare protons. This produces a state in which the hydrogen becomes metallic. \nColorful latitudinal bands, atmospheric clouds and storms illustrate Jupiter's dynamic weather systems. The cloud patterns change within hours or days. The Great Red Spot is a complex storm moving in a counter-clockwise direction. At the outer edge, material appears to rotate in four to six days; near the center, motions are small and nearly random in direction. An array of other smaller storms and eddies can be found through out the banded clouds. \n\nAuroral emissions, similar to Earth's northern lights, were observed in the polar regions of Jupiter. The auroral emissions appear to be related to material from Io that spirals along magnetic field lines to fall into Jupiter's atmosphere. Cloud-top lightning bolts, similar to superbolts in Earth's high atmosphere, were also observed. \n\nJupiter's Ring\nUnlike Saturn's intricate and complex ring patterns, Jupiter has a simple ring system that is composed of an inner halo, a main ring and a Gossamer ring. To the Voyager spacecraft, the Gossamer ring appeared to be a single ring, but Galileo imagery provided the unexpected discovery that Gossamer is really two rings. One ring is embedded within the other. The rings are very tenuous and are composed of dust particles kicked up as interplanetary meteoroids smash into Jupiter's four small inner moons Metis, Adrastea, Thebe, and Amalthea. Many of the particles are microscopic in size. \n\nThe innermost halo ring is toroidal in shape and extends radially from about 92,000 kilometers (57,000 miles) to about 122,500 kilometers (76,000 miles) from Jupiter's center. It is formed as fine particles of dust from the main ring's inner boundary 'bloom' outward as they fall toward the planet. The main and brightest ring extends from the halo boundary out to about 128,940 kilometers (80,000 miles) or just inside the orbit of Adrastea. Close to the orbit of Metis, the main ring's brightness decreases. \n\nThe two faint Gossamer rings are fairly uniform in nature. The innermost Amalthea Gossamer ring extends from the orbit of Adrastea out to the orbit of Amalthea at 181,000 kilometers (112,000 miles) from Jupiter's center. The fainter Thebe Gossamer ring extends from Amalthea's orbit out to about Thebe's orbit at 221,000 kilometers (136,000 miles). \n\nJupiter's rings and moons exist within an intense radiation belt of electrons and ions trapped in the planet's magnetic field. These particles and fields comprise the jovian magnetosphere or magnetic environment, which extends 3 to 7 million kilometers (1.9 to 4.3 million miles) toward the Sun, and stretches in a windsock shape at least as far as Saturn's orbit - a distance of 750 million kilometers (466 million miles). \n\nJupiter Statistics \nMass (kg) 1.900e+27 \nMass (

Can you think of ANY objects in space?\n\nHow do you suppose they were discovered?\n\nF'r Chrissakes, clearly this is a schoolwork question. DO YOUR OWN HOMEWORK! IT'S SUPPOSED TO TEACH YOU, NOT YAHOO ANSWERS VOLUNTEERS, HOW TO DO RESEARCH.\n\nYeesh!

The religious answer would be that God created the sun and Adam discovered it. It certainly was not discovered by Galileo, that is just silly.\n\nThe scientific answer would be that it has been known since prehistoric times and was not discovered by any one person.

It is not yet known if Jupiter has a solid surface.  If it does, then the solid part of the planet can only make up a very small fraction of the volume of the planet.\n\nSaying that the Jupiter's atmosphere constitutes a "surface" (as some answerers have proposed) is not really correct in that one cannot point to a surface at which the atmosphere "ends".  Like Earth's atmosphere, Jupiter's atmosphere simply becomes more and more tenuous as one moves further from the planet (in an approximately exponentially decreasing fashion).  Picking a pressure at which the atmosphere "ends" is a arbitrary choice.

Yes I have.  They featured an article about it on Space.com and the NASA website.  Seems that many other Kuiper belt objects have mutiple satellites (moons) as well.  It will be interesting what the New Horizon probe will find when it gets out to Pluto and beyond.  I am hoping the launch will be on time so it can use the gravitational assist from Jupiter to get there quicker.  There was a NASA site where a person could get their name placed on a CD that is launching with the probe.  Several of my friends and I signed up and our names are on that disk now.

now dis question i love!!! ok, u would need an anti gravity suit which would allow u to sat on top of jupiter's layer because its gas. if u put ur foot on jupiter, it would sink. so an anti gravity suit would be advised. also, ud probably need food (obviously) a flying rover so u can observe jupiter and even a weather and observations kit to be able to see the Grest red Spot. If ur goin to Jupiter's moons, u should bring stuff to help u survive, and maybe even a few scientists who can find out if Jupiter's moons' substance can help the Earth in any way. R u planning to be an astronaut or r one?? if u are, could u email me. becuz i love space and everything about it

There is a resource located at http://www.drboylan.com/ that will assist you with your question.  Dr. Boylan has been researching this area for many years and describe the advances the U.S. has made from Space Visitor technology.  Some examples are the Stealth Bombers and War Ships.  Hope this helps.

The sun DOESN'T know the ship is there, and it doesn't have to:  Gravity is a warping or deformation of the four-dimensional fabric of space-time, not an actual pulling.\n\nThe earth travels around the sun because the earth is actually travelling IN A STRAIGHT LINE in its "local" space.  The end result is an ellipse because the space around the sun is literally bent into a curved shape.\n\nSo, your ship can travel faster than light, but it can't travel faster than space -- which is to say, wherever it arrives after its hyperspace trip -- it IS where it IS and if the space is bent the ship will follow the contour of its local space regardless of how far it is from the source of the gravitational spacetime warping.  No information or "graviton" needs to actually travel from the ship to the sun.

Yeah, you're probably watching too much Sci Fi stuff.\nI wouldn't worry about space aliens too much.  Anything intelligent enough to find us would most likely rather befriend us than attack us.\n\nThe Voyager 1 space craft is about about twice as far away from the Sun as Pluto.  It's traveling at about 1 million miles per day.  After breaking through the heliosphere Voyager will have reached interstellar space.  It's nuclear batteries are expected to last until the year 2020 or so.\n\nThe Voyager 2 space craft is about 80% as far from the Sun as Voyager 1.  It is traveling in a south ward direction from the planetary plane.

The Pathfinder went to Mars, not the moon\n\nMars Pathfinder - USA Lander & Surface Rover - 264 kg (lander), 10.5 kg (rover) - (December 4, 1996 - September 27, 1997) \nMars Pathfinder arrived at Mars on July 4, 1997 and impacted the surface at 16:57 UT (12:57 PM EDT) at a velocity of about 18 m/s (40 mph). It bounced about 15 meters (50 feet) into the air, bouncing another 15 times and rolling before coming to rest approximately 2.5 minutes after impact and about 1 km from the initial impact site. The landing site was in the Ares Vallis region is at 19.33 N, 33.55 W and was named the Sagan Memorial Station. A six-wheel rover, named Sojourner, rolled onto the Martian surface on July 6 at about 05:40 UT. Mars Pathfinder returned 2.6 billion bits of information, including more than 16,000 images from the lander and 550 images from the rover, as well as more than 15 chemical analyses of rocks and extensive data on winds and other weather factors. The last successful data transmission was on September 27, 1997, the 83rd day of the mission since landing on the surface. This is the second mission in NASA's low-cost Discovery series.

Dear Sir:\n\nWhile there have been some actual transmissions from Earth to the Solar System seeking echos, and some of this might still be going on in a coordinated fashion, as I understand it, the primary mission of the existing radio telescopes is to "Listen" to upper wavelength radio emissions from gas clouds, and other phenomina in the universe. Of course, once some interesting\nradio emissions are detected, a full spectrum scan of the target is most likely conducted to determine the full extent of radio\nsignals from that source.\n\nOther radio transmissions are made from Earth to our traveling Space Probes and Robotic Explorers at various locations in the Universe. A continual litany of telemetry, television and voice signals also flows between the Space Station and Ground Control Center to keep a constant watch on the health, status, and activities of the space crew, mission, and the station itself.\n\nI will defer to someone from one of those positions for an\nanswer as to the power and frequency of transmissions from Earth to the Space Station, Earth to the Robot Explorers, and Earth to the existing Space Probes way out in deep space.\nMy guess is that these various transmissions take place on frequencies between 2,500 Mhz and 40,000 Mhz. That is a \nvery large radio spectrum. \n\nSince my response turns around your question, in that I am telling you that the biggest radio telescopes listen rather than\ntransmit, let me also tell you that the biggest radio telescopes are not simply single structures at a given location. In recent years a scheme for the linkage of two or more radio telescopes was developed. Therefor, the biggest radio telescope would be an electronic combination of the signals from most of the largest installations on Earth. A lot of work has been done in that vein in recent years. Using more than one receiving antenna provides an easy means for researchers to filter out local ground (earthbound) noise generators and radio disturbances. Signals heard at the same time by widely separated receiving antennas (and equipment) are most probably from the sighted target source (assuming both antennas are aimed at the same target). It is also interesting to know that the radio signals that are received require a vast amount of processing to be identified and detected. The processing of the radio telescope incoming signals takes a huge array of computers and some very complex software programs to yield useable data.\n\nYes, radio waves do go on forever. However, their strength at the point of interception decreases by the square of the distance from the source. So, the strength of radio waves become very, very weak as you move into distances like 100,000,000 miles.\nThe wave front would continue out like rings of water in a pond until they hit something and bounced back off of it. In that sense,\na portion of the radio wave would not go on forever, but would become a new wave moving in the oposite direction from the new source (which was the object that the wave struck). The\nrest of the wave front would continue on until it struck something, and we repeated the above scenario. The exact same thing happens to signals transmitted from a sonar transducer in the water. Those devices are used to detect the depth of the bottom of rivers/oceans (depth finder), fish in the water (fish finder), or even other vessels (sub hunting). Sonar, uses sound waves and not radio waves, but the principle is almost the same.  Sound waves radiate out. Nearby echos are strong enough to be detected with existing equipment and are plotted and displayed on information screens. Some echos are so weak coming back that the existing equipment cannot detect/plot/or display  them.\n\nRegards,\nZah

An ion engine will get you there the fastest. You get the biggest delta-vee per kg of exhaust. \n\nProblem is, in general you only get one encounter with a specific planet once each solar orbit, and you can only get a kick so large each time. I suppose you can hypothesize a super convenient planetary alignment that could shave off some time, but you might spend a long time waiting for that particular configuration.  A lot of really smart people spent a lot of time developing the computational tools to come up with the VEEGA and VVEJGA options.  I doubt the population here is going to come up with anything a lot better.\n\nYou can read more about the DS1 ion propulsion experimental system here:\nhttp://nmp.nasa.gov/ds1/tech/ionpropfaq.html\n\nThe first science mission using ion propulsion is the Pluto bound New Horizons.  Thanks to this tech, it will reach pluto in 10 short years and reaches Jupiter for a gravity assist in only 1 year.\n\nhttp://pluto.jhuapl.edu/mission/mission_timeline.html
