Ganymede Images Captured By Amateur Astronomer
2012-09-28 04:13:56

Lee Rannals for redOrbit.com - Your Universe Online Astronomers reported at the European Planetary Science Congress that they have produced the first amateur albedo map of Jupiter's moon Ganymede. This map shows off the higher areas of reflectivity on an object's surface, recording where material is bright or darker in areas. The map developed by the astronomers closely aligns with professional images of Ganymede's surface, showing off features like Phrygia Sulcus and the Nicholson...

Russia Considering Cooperation In JUICE Jupiter Mission
2012-07-25 05:25:46

Lee Rannals for redOrbit.com - Your Universe Online The Russian space agency is considering participating in a developing project to send a spacecraft to Jupiter. The European Space Agency (ESA) is starting-up the Jupiter Icy Moon Explorer (JUICE) project, and Russian scientists are considering the possibility of participating, according to a Voice Of Russia report. Lee Fletcher from JUICE´s Oxford University scientific group presented the objectives of the mission at the...

Committee Selects JUICE Jupiter Probe As Next Big Endeavor
2012-05-02 11:47:08

Lee Rannals for RedOrbit.com The European Space Agency (ESA) has selected a Jupiter probe to be its next "large class" space endeavor after a five-year-long competition. The JUpiter Icy moon Explorer (JUICE) has been approved at a meeting of member state delegations in Paris. The probe would be built in time for launch in 2022, and will take eight years to reach the Jovian system. JUICE is a nearly five-ton satellite that aims to orbit Jupiter's moon Ganymede, as well as make...

JUICE Frontrunner In ESA Proposals
2012-04-19 12:53:51

The Jupiter Icy Moon Explorer (JUICE) proposal to study the moons of Jupiter is leading the pack of proposed missions. The mission would launch in 2022 to study Jupiter's moons and determine whether any of them are capable of supporting life. JUICE, according to BBC News, is waiting for a European space committee to meet and discuss the mission, along with other contenders, in May. The spacecraft in the mission would study three of Jupiter's Galilean moons, using gravity of the large...

Geologic Map Reveals Io's Otherworldly Volcanoes
2012-03-21 04:41:48

A team of scientists led by Arizona State University has produced the first complete geologic map of Jupiter´s moon, Io. Published by the US Geological Survey, the new map reveals geologically unique features, volcanoes, and lava flows as well as some relative ages of the moon. Galileo first discovered Io more than 400 years ago. Io is the largest and innermost moon to orbit the planet Jupiter and has been the subject of many scientific studies as well as intense observation. Existing...

Cassini Detects Oxygen On Saturn's Moon Dione
2012-03-02 13:18:55

Researchers report this week in the journal Geophysical Research Letters that NASA's Cassini spacecraft has detected oxygen on one of Saturn's moons. They said their finding increases the likelihood of finding the ingredients for life on one of the moons orbiting gas giants. The ice moon, Dione, has no liquid water and does not have the proper conditions to support life, Andrew Coates of the University College London said.  However, he said that it is possible that other moons of...

With input from scientists around the world, American and European scientists working on the potential next new mission to the Jupiter system have articulated their joint vision for the Europa Jupiter System Mission. The mission is a proposed partnership between NASA and the European Space Agency. The scientists on the joint NASA-ESA definition team agreed that the overarching science theme for the Europa Jupiter System Mission will be "the emergence of habitable worlds around gas giants."...

The frigid ice of Jupiter's moon Europa may be hiding more than a presumed ocean: it is likely the scene of some unexpectedly fast chemistry between water and sulfur dioxide at extremely cold temperatures. Although these molecules react easily as liquids-they are well-known ingredients of acid rain-Mark Loeffler and Reggie Hudson at NASA's Goddard Space Flight Center in Greenbelt, Md., now report that they react as ices with surprising speed and high yield at temperatures hundreds of degrees...

Jupiter's moon Io could be a potential target to look for extraterrestrial life. Io is the innermost of Jupiter's large moons and has the most volcanic activity in the solar system, with plumes of matter rising 186 miles above the surface. This activity is due to Jupiter's powerful gravitational pull, which causes Io's tormented solid crust to bulge up and down 328 feet or more, generating intense heat in Io due to friction. Io generally is considered a poor candidate for life because of...

Differences in the number and speed of cometary impacts onto Jupiter's large moons Ganymede and Callisto some 3.8 billion years ago can explain their vastly different surfaces and interior states, according to research by scientists at the Southwest Research Institute appearing online in Nature Geoscience Jan. 24, 2010. Ganymede and Callisto are similar in size and are made of a similar mixture of ice and rock, but data from the Galileo and Voyager spacecraft show that they look different at...

Aquila (the Eagle) Constellation -- Location: Northern Hemisphere; Coordinates: Right Ascension: 20h; Declination: 05; Source: Various cultures - Greek, Arab, Persian, Indian, Japanese, Chinese, Korean The story behind the name In the ancient Middle Eastern and Mediterranean cultures, the constellation Aquila is seen as the shape of a flying bird. The pattern contains three prominent stars that can be seen to outline the wings of a bird, but are also the focus of quite different myths...

Jupiter's Moon Callisto -- With a diameter of over 4,800 km (2,985 miles), Callisto is the third largest satellite in the solar system and is almost the size of Mercury. Callisto is the outermost of the Galilean satellites, and orbits beyonds Jupiter's main radiation belts. It has the lowest density of the Galilean satellites (1.86 grams/cubic centimeter). Its interior is probably similar to Ganymede except the inner rocky core is smaller, and this core is surrounded by a large icy...

Jupiter's Moon Ganymede -- Ganymede is the largest satellite in the solar system with a diameter of 5,268 km (3270 miles). It is larger than Mercury and Pluto, and three-quarters the size of Mars. If Ganymede orbited the Sun instead of orbiting Jupiter, it would easily be classified as a planet. If Ganymede orbited the Sun instead of Jupiter it could be classified as a planet. Like Callisto, Ganymede is most likely composed of a rocky core with a water/ice mantle and a crust of rock and...

Jupiter's Moon Europa -- Europa is a puzzle. The sixth largest moon in our Solar System, Europa confounds and intrigues scientists. Few bodies in the Solar System have attracted as much scientific attention as this moon of Jupiter because of its possible subsurface ocean of water. The more we learn about this icy moon, the more questions we have. Because the nature of science is to ask questions, we cannot resist the mystery of Europa and its potential for possessing an ocean. Early...

Jupiter's Moon Io -- Looking like a giant pizza covered with melted cheese and splotches of tomato and ripe olives, Io is the most volcanically active body in the solar system. Volcanic plumes rise 300 kilometers (190 miles) above the surface, with material spewing out at nearly half the required escape velocity. A bit larger than Earth's moon, Io is the third largest of Jupiter's moons, and the fifth one in distance from the planet. Although Io always points the same side toward...
