Sounds Of Space
2013-12-20 16:31:24

Lee Rannals for redOrbit.com - Your Universe Online A scientist from the University of Leicester is helping to reveal the sounds of space by using satellite data. Some areas of space are so quiet you can hear your heart beat, but there are other areas that have the capacity to be as noisy as places on Earth. A multimedia composer at the University’s Space Center decided to generate a few of the surprising Earth-like sounds one could find in space. Andrew Williams used data collected from...

Hubble Finds Europa Water Vapor
2013-12-12 13:10:28

[ Watch the Video: Europa Shows Evidence Of Liquid Water ] Brett Smith for redOrbit.com - Your Universe Online For years scientists have suspected the presence of liquid water under the surface of Jupiter’s moon Europa. Now, the Hubble Space Telescope has detected evidence of water vapor eruption from the moon’s surface, according to a new report published in Science Express on Thursday. The space agency is looking to observations from other sources to confirm Hubble’s initial...

Clay Minerals Found On Europa
2013-12-11 15:38:16

Lee Rannals for redOrbit.com - Your Universe Online Jupiter’s icy moon Europa appears to have clay-type minerals on its surface, according to new data from NASA’s Galileo mission. Scientists at the American Geophysical Union meeting in San Francisco say they have identified clay-like minerals on Europa for the first time. This finding could also imply that Europa carries organic materials. "Organic materials, which are important building blocks for life, are often found in comets...

DARPA Is At Work Developing The Latest High-Tech Spy Satellite
2013-12-10 13:19:11

[ Watch the video: DARPA MOIRE Concept Video ] Lee Rannals for redOrbit.com - Your Universe Online DARPA says it has plans to develop an ultimate spy satellite capable of viewing 40 percent of the Earth’s surface at once. The Membrane Optical Imager for Real-Time Exploitation (MOIRE) space telescope will be launched as a tightly packed cluster of petals 20 feet in diameter, helping it stretch out to 68 feet across. It will record the Earth’s surface with high resolution imagery,...

Lunar Impact Crater Has A Diverse Subsurface Mineralogy
2013-12-10 05:53:55

redOrbit Staff & Wire Reports - Your Universe Online The presence of a diverse group of minerals in the largest lunar impact crater could help scientists gain new insight into the Moon’s interior, as well as the evolution of its crust and mantle, claims new research appearing online in Journal of Geophysical Research: Planets. Dan Moriarty, a graduate student from Brown University, and his colleagues analyzed data collected from the Moon Mineralogy Mapper instrument aboard India's...

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...
