ESA Discovers Origin Of Jupiter's Mysterious Atmospheric Water
2013-04-23 13:41:09

Lee Rannals for redOrbit.com — Your Universe Online The European Space Agency (ESA) says it has unraveled the mystery as to the origin of water observed in the upper atmosphere of Jupiter. ESA's Herschel space observatory found evidence that the water in this part of Jupiter's atmosphere was delivered by the dramatic impact of comet Shoemaker-Levy 9 in July 1994. During this collision, a string of 21 comet fragments pounded into the southern hemisphere of Jupiter, leaving dark...

Windows Into Europa's Icy Interior
2013-04-15 05:40:10

redOrbit Staff & Wire Reports - Your Universe Online By taking a second look at observations made more than a decade ago, NASA scientists have discovered regions that might give them the best look at the deep saltwater ocean beneath the icy shell of Jupiter´s moon Europa. The surface of this natural satellite exposes material originating both from the inside of the moon and from matter and energy coming from above, the US space agency explained in a statement on Friday. In...

Building Blocks For Life May Be Found On Jupiter's MoonEuropa
2013-04-05 13:29:24

Brett Smith for redOrbit.com - Your Universe Online The building blocks of life are strewn across the galaxy on or beneath many planetary surfaces and new evidence from NASA suggests that the necessary cocktail for life could be sitting right on one of Jupiter´s moons. According to the study, Jupiter´s moon Europa has enough hydrogen peroxide on its surface to potentially support life if it were to somehow mix with the ocean trapped beneath the moon´s icy surface. The...

VolcanoesOn Io Are In The Wrong Place

April Flowers for redOrbit.com - Your Universe Online With hundreds of volcanoes, some erupting lava fountains up to 250 miles high, Jupiter's moon Io is the most volcanically active world in our Solar System. According to NASA and European Space Agency (ESA) researchers, though, concentrations of volcanic activity are significantly displaced from where they are expected to be based on models used to predict how the moon's interior is heated. The team, which included scientists from...

Window Into Europa’s Ocean Opened By Astronomers

W. M. Keck Observatory With data collected from the mighty W. M. Keck Observatory, California Institute of Technology (Caltech) astronomer Mike Brown – known as the Pluto killer for discovering a Kuiper-belt object that led to the demotion of Pluto from planetary status – and Kevin Hand from the Jet Propulsion Laboratory (JPL) have found the strongest evidence yet that salty water from the vast liquid ocean beneath Europa´s frozen exterior actually makes its way to the...

WISSARD Team Retreives Samples From Subglacial Antarctic Lake
2013-01-29 14:09:59

Lawrence LeBlond for redOrbit.com - Your Universe Online Update 1 (January 29, 2013): A National Science Foundation (NSF)-funded research team has successfully drilled through 2,600 feet of ice in Antarctica on January 28 to reach subglacial Lake Whillans. Just a day later and the team said they have pulled up the first water and sediment samples from the depths of the under-ice lake that have been isolated for thousands of years. The Whillans Ice Stream Subglacial Access Research...

JPL Bubbles Up Organics Using Ocean Vent Simulator
2013-01-17 09:25:23

NASA's Jet Propulsion Laboratory This week, fizzy ocean water and the alkaline fluid that bubbles up from deep ocean vents are coursing through a structure at NASA's Jet Propulsion Laboratory in Pasadena, Calif. that is reminiscent of the pillared Emerald City in the Wizard of Oz. Scientists with the NASA Astrobiology Institute's JPL Icy Worlds team have built this series of glass tubes, thin barrels and valves with a laser and a detector system. The set-up mimics the conditions at...

Europe is, by regulation, one of the world’s seven continents. Consisting of the westernmost peninsula of Eurasia, Europe is generally divided from Asia by the watershed divides of the Ural and Caucasus Mountains, the Ural River, the Black and Caspian Seas, and the waterways that connect the Black and Aegean Seas. It is bordered by the Arctic Ocean towards the north, Atlantic Ocean to the west, Mediterranean Sea to the south, and the Black Sea and connected waterways to the southeast....

Galileo Probe -- The Galileo probe was an unmanned probe sent by NASA to study the planet Jupiter and its moons. Named after the astronomer Galileo Galilei, it was launched on October 18 1989 by the Space Shuttle Atlantis and arrived at Jupiter on December 7 1995. Galileo's launch had been significantly delayed by the hiatus in Space Shuttle launches that occurred after the Space Shuttle Challenger disaster, and new safety protocols that were implemented as a result forced Galileo to use...

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...
