Volcano Controversy Settled Using Chemistry ‘Trick’
2013-02-12 15:01:41

Brett Smith for redOrbit.com - Your Universe Online Volcanic eruptions have been known to cause global cooling, although the extent of this cooling has been a topic of scientific controversy. Now a team of atmosphere chemists from the Tokyo Institute of Technology and the University of Copenhagen has devised a method for determining which historical cooling periods are the results of volcanic eruptions. When a large volcano erupts, it can propel gases high into the stratosphere where...

Lack Of Craters On Titan Makes Moon Look Younger
2013-01-17 15:10:00

Lee Rannals for redOrbit.com — Your Universe Online New research based on observations from NASA's Cassini spacecraft show that Titan, Saturn's largest moon, may look younger than it really is. While most moons display their age through their thousands of craters, NASA said that Titan's craters are being erased, giving it a 'Benjamin Button' appearance. "Most of the Saturnian satellites - Titan's siblings - have thousands and thousands of craters on their surface. So far on...

Lawrence LeBlond for redOrbit.com - Your Universe Online Update: January 19, 2013 On Monday evening, astronomers (both amateurs and pros) across the country will be looking up to the skies to witness the super close dance between Jupiter and the Moon. Slooh Space Camera will also be there broadcasting live feeds of the event, giving everyone a shot at seeing the chance encounter. The waxing gibbous moon will appear about one degree south of Jupiter on Monday night, January 21. This...

Fusion-io Prepares The Way For All-Flash Data Centers
2013-01-16 13:35:36

Lee Rannals for redOrbit.com - Your Universe Online Fusion-io has launched its new ioScale product line, paving the way for an eventual all-flash data center for companies in the not-so-distant future. The ioScale turns the all-flash-drive data center into a more realistic idea for companies that rely on high-performance hardware. Each of ioScale's units provides up 3.2 terabytes of Fusion ioMemory capacity at $3.89 per gigabyte. Fusion-io claims to include a number of benefits with...

NASA Cluster Mission Sheds Light On Mysteries Of Solar Winds
2013-01-09 14:42:24

Brett Smith for redOrbit.com - Your Universe Online Data collected from the European Space Agency´s (ESA) Cluster Mission showed for the first time how turbulence within solar wind can create a warming effect as the charged particles travel away from the sun. The solar wind is formed by electrically charged plasma being ejected from the sun´s super hot atmosphere. According to a new report in the new issue of Physical Review Letters based on Cluster data, very small...

Christmas Light Show And The Christmas Star

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...
