redOrbit Staff & Wire Reports - Your Universe Online While astronomers have long believed that Jupiter’s moon Ganymede was home to a thick ocean sandwiched between two layers of ice, a new NASA-funded research project now claims that the largest natural satellite in our solar system could actually have several layers of ice and ocean stacked one upon another. Writing in the journal Planetary and Space Science, Steve Vance of the Jet Propulsion Laboratory (JPL) in Pasadena,...

Cassini Eyes Possible New Moon Forming In Saturn's Orbit
2014-04-15 08:45:46

Brett Smith for redOrbit.com - Your Universe Online Newly released images from NASA’s Cassini probe have revealed the “birthing” of a tiny moon in orbit around Saturn. The images, taken exactly one year ago on Tuesday, showed evidence of the formation of a tiny icy moon, named “Peggy” – according to a new report on the find in the journal Icarus. The study authors said the discovery could provide information about the formation of Saturn’s other moons as well as the...

[ Watch the Video: Crater Identification Variability Using Citizen Scientists ] April Flowers for redOrbit.com - Your Universe Online Astronomers believe that Europa, one of Jupiter's moons, has a huge ocean beneath its icy surface. They have theorized that water, salts and gasses that have dissolved into that ocean rise to the surface, generating the enigmatic geological formations associated with the red-tinged formations seen on the moon's surface. A group of researchers from the...

Voyager, Galileo Spacecraft Images Used To Create Geological Map Of Jupiter's Largest Moon

[ Watch the Video: Rotating Globe of Ganymede Geology ] Lee Rannals for redOrbit.com - Your Universe Online Scientists, led by Geoffrey Collins, of Wheaton College, have produced the first global geological map of Jupiter’s largest moon. The map, now published by the USGS as a global map, combines images of Ganymede taken by NASA's Voyager 1 and 2 spacecraft and Galileo orbiter. It is the first global, geologic map of Jupiter’s seventh moon, providing the geologic character of...

Europa's Subsurface Ocean Currents And Patterns Act As A Heat Transfer

[ Watch the Video: Saturn's Moon Europa Has A Dynamic Subsurface Ocean ] April Flowers for redOrbit.com - Your Universe Online Researchers from The University of Texas at Austin's Institute for Geophysics (UTIG), the Georgia Institute of Technology, and the Max Planck Institute for Solar System Research have revealed that the subsurface ocean on Jupiter's moon Europa might have deep currents and circulation patterns. These currents and patterns have heat and energy transfers capable of...

New Sensor Developed To Scan Planetary, Lunar Atmospheres

Brett Smith for redOrbit.com - Your Universe Online Researchers from Chalmers University of Technology in Sweden have announced the development of a groundbreaking sensor that could eventually be used to scan the atmospheres of Jupiter’s moons and other planetary bodies. Referred to as a terahertz receiver, the sensor was developed under a partnership involving several European research institutions. “The unique sensor is compact, light-weight, robust and operates at room...

Jupiter Moon Europa

Lee Rannals for redOrbit.com - Your Universe Online Researchers announced at the European Planetary Science Congress in Madrid on Tuesday that the liquid water found on one of Jupiter's moons may not always be in that state. Europa is believed to be hosting a subsurface ocean of liquid water beneath, but a new study suggests that this water does not stay in this liquid state for longer than a few tens of thousands of years. Astronomers believe the moon contains a water shell about 62...

Scientists say they have found convincing evidence that Saturn's moon Enceladus has a large-scale subterranean saltwater ocean. The discovery was made using data collected during the Cassini-Huygens mission to Saturn. The plumes of shooting water vapor and tiny grains of ice into space were originally discovered emanating from Enceladus by the Cassini spacecraft in 2005. The researchers from the University of Heidelberg and University of Colorado said during three of Cassini's passes...

Planetary scientist Francis Nimmo will outline the impact of ice dynamics on the habitability of the moons of Saturn and Jupiter on Tuesday, December 15, at the annual meeting of the American Geophysical Union in San Francisco. Scientists once thought that life could originate only within a solar system's "habitable zone," where a planet would be neither too hot nor too cold for liquid water to exist on its surface. But according to Nimmo, a professor of Earth and planetary sciences at the...

Researchers in Europe released a new report on Wednesday that suggests the geyser seen on the surface of Saturn's moon Enceladus could be fed by a salty ocean underneath the surface. Writing in the journal Nature, scientists said that the discovery could support theories of the existence of extraterrestrial life. Scientists first discovered Enceladus' habit of spewing a mix of water vapor, gas and tiny grains of ice into space in 2005 with observations from the Cassini spacecraft. Enceladus...
