New Volcanic Revelations May Help Predict When Eruptions Will Occur
2014-05-05 09:10:30

[ Watch the Video: New Insight May Help Predict Volcanic Eruption Behavior ] Gerard LeBlond for redorbit.com - Your Universe Online Volcanologists from the University of Liverpool have discovered how lava dome volcanoes erupt. This could help develop methods on predicting how volcanoes will act. The process of frictional melting determines how the volcano will erupt. The speed of the lava rise and how much friction it creates is determined by this process. Within the lava dome the...

NASA Looking For External Concepts For Mission To Oceanic Jovian Moon
2014-04-29 03:21:27

Dwayne Brown, NASA's Jet Propulsion Laboratory NASA has issued a Request for Information (RFI) to science and engineering communities for ideas for a mission to Europa that could address fundamental questions of the enigmatic moon and the search for life beyond Earth. The RFI's focus is for concepts for a mission to Europa that costs less than $1 billion, excluding the launch vehicle that can meet as many of the science priorities as possible recommended by the National Research...

Martian Meteorites Offer Evidence Of Early Atmosphere On Red Planet
2014-04-17 06:47:34

Lawrence LeBlond for redOrbit.com - Your Universe Online Martian meteorites that fell to Earth are revealing secrets of an early atmosphere on Mars that is hidden in the chemical signatures of each ancient rock. Geologists, who collected and studied 40 of these otherworldly rocks, have found an important key to how the atmospheres of Mars and Earth diverged very early in the evolution of the Solar System. The results of this study, published in the journal Nature, will help guide...

Data will help scientists read Curiosity Mars rover samples for signs of life, says UMD coauthor of study published today in Nature. (PRWEB) April 16, 2014 Geologists who analyzed 40 meteorites that fell to Earth from Mars unlocked secrets of the Martian atmosphere hidden in the chemical signatures of these ancient rocks. Their study, published April 17 in the journal Nature, shows that the atmospheres of Mars and Earth diverged in important ways very early in the 4.6 billion year...

[ 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...

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...
