Yellowstone Volcano Debate: Both Sides May Be Right
2013-04-16 05:23:36

Volcanism in the Yellowstone region was caused by the defunct pieces of a former mantle plume that were severely deformed. Circulation currents, driven by the movement of tectonic plates at the Cascades subduction zone, also affected the plume.

Windows Into Europa's Icy Interior

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.

Volcanic Activity Would Have Helped Mars Sustain Liquid Water
2013-04-09 10:17:31

A new study suggests that Earth’s atmosphere is largely the product of carbon dioxide gas moving from the mantle to the surface through volcanic activity; if similar activity were to happen on Mars – the planet would be able to sustain liquid water.

Building Blocks For Life May Be Found On Jupiter's MoonEuropa

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.

VolcanoesOn Io Are In The Wrong Place

Concentrations of volcanic activity in Jupiter's moon Io are significantly displaced from where they are expected to be based on models used to predict how the moon's interior is heated.

Unmanned Aircraft Used To Help Study Volcanic Plumes
2013-04-02 05:11:35

Last month, Earth science researchers from NASA traveled to Turrialba Volcano near San Jose, Costa Rica. The research team was there to study the chemical environment of the volcano by flying a Dragon Eye unmanned aerial vehicle into the sulfur dioxide plume and over its summit crater.

Model Shows How Carbon Escapes From Deep Earth To Surface

Computer simulations of water under extreme pressure reveals how carbon might one day be recycled from hundreds of miles below the surface of the Earth, according to researchers at the University of California, Davis and Johns Hopkins University.

Satellite -- A satellite is an object that orbits another object. With sufficient tangential velocity, the object does not collide with the primary object it orbits, but maintains a distance from that object as the rate at which it falls towards that object is similar to the rate that it travels away, thus the object orbits the primary object and becomes a satellite. In other words: gravitational force serves as the centripetal force needed to make the object circle the primary...

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 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...
