Saturn Storm Aftermath Seen By Cassini
2012-10-25 12:54:42

[ Watch the Video: Saturn´s Record-Setting Storm ] Lee Rannals for redOrbit.com - Your Universe Online As the "Perfect Storm" begins to set its place on the East Coast, there has been another massive storm that has taken place, but not on this planet. NASA's Cassini spacecraft tracked the aftermath of a rare massive storm on Saturn, revealing disturbances in the planet's upper atmosphere long after the visible signs of the storm abated. Data from Cassini's composite infrared...

WASHINGTON, Oct. 25, 2012 /PRNewswire-USNewswire/ -- NASA's Cassini spacecraft has tracked the aftermath of a rare massive storm on Saturn. Data reveal record-setting disturbances in the planet's upper atmosphere long after the visible signs of the storm abated, in addition to an indication the storm was more forceful than scientists previously thought.

Strange Weather Patterns On Uranus
2012-10-21 08:59:09

April Flowers for redOrbit.com — Your Universe Online New, exquisitely detailed, high-resolution images of Uranus show off its complex weather patterns and new features of the planet that scientists can't explain yet. Uranus, the seventh planet from the Sun, is an ice giant composed mainly of frozen methane, water, ammonia and hydrocarbons. In 1986, Voyager 2 passed by Uranus and returned the iconic image that most associate with the planet. This image showed a smooth, blue-green...

Jupiter In Turmoil From Above And Below
2012-10-18 07:46:08

[ Watch the Video: What is Jupiter? ] April Flowers for redOrbit.com - Your Universe Online In ancient Rome, Jupiter was the King of the gods and the god of sky and thunder with his mighty thunderbolt. He would certainly be pleased with the changes occurring on his namesake planet. Jupiter the planet is continually being peppered with small space rocks, the atmosphere is changing colors in wide belts, hotspots are vanishing and reappearing, and clouds are gathering and dissipating over...

Giant Impacts Formed The Moons Of Saturn
2012-10-17 14:58:59

Lee Rannals for redOrbit.com — Your Universe Online Planetary scientists claim in a paper published in Icarus that Saturn's moons may have formed due to giant impacts. Erik Asphaug, professor of Earth and Planetary Sciences at the University of California, Santa Cruz (UCSC), presented the new model at the annual meeting of the Division for Planetary Sciences of the American Astronomical Society (AAS). Asphaug and co-author Andreas Reufer of the University of Bern found that...

Astronomers Monitor Volcanic Activity On Jupiter’s Moon Io From Earth
2012-10-17 11:01:21

Lawrence LeBlond for redOrbit.com - Your Universe Online Watching active volcanic eruptions should be done so from a safe distance. Observing active eruptions here on Earth can be easily accomplished from the comfort of your home with proper equipment. But observing an Earthen volcanic eruption from home is nothing when compared to what a group of California researchers have been privy to. Using an ingenious combination of ground-based telescopic surveys and archival data, the Golden...

Cassini Going Strong 15 Years After Launch
2012-10-16 09:04:52

Brett Smith for redOrbit.com - Your Universe Online As the Cassini spacecraft hurtles around Saturn along its continuing mission, NASA announced the fifteen-year anniversary of the probe´s launch this week. The $3.3-billion mission lifted off the launch pad on October 15, 1997 and has traveled over 3.8 billion miles since – flying past Venus twice and Jupiter once en route to entering orbit around the ringed planet in 2004. The mission has provided a treasure trove of...

Asteroids Following Jupiter’s Solar Orbit Show Their True Colors
2012-10-16 08:51:09

Lawrence LeBlond for redOrbit.com - Your Universe Online Jovian asteroids that orbit the Sun on the same trajectory as the gas giant Jupiter have been studied more closely by scientists using NASA´s Wide-field Infrared Survey Explorer (WISE). These asteroids travel in packs, like hungry wolves stalking their prey, some racing ahead of the gas giant, while others trail behind. The observations of these Jovian predators are the first detailed look at their true colors. Scientists...

Solar System Shaped By Stellar Shockwaves
2012-09-28 08:20:29

Lee Rannals for redOrbit.com - Your Universe Online Shockwaves emitted by our young sun in its early days would have caused the planets in our solar system to form, according to research presented at the European Planetary Science Congress. Astronomers modeled the movements of particles in fluids and gases in the gas cloud from which our Sun accreted. Their work suggests that during its early days, the Sun emitted a series of shockwaves that rippled out into the remaining material....

Ganymede Images Captured By Amateur Astronomer
2012-09-28 04:13:56

Lee Rannals for redOrbit.com - Your Universe Online Astronomers reported at the European Planetary Science Congress that they have produced the first amateur albedo map of Jupiter's moon Ganymede. This map shows off the higher areas of reflectivity on an object's surface, recording where material is bright or darker in areas. The map developed by the astronomers closely aligns with professional images of Ganymede's surface, showing off features like Phrygia Sulcus and the Nicholson...

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...

Retrograde Motion -- Retrograde motion is the orbital motion of a body in a direction opposite that which is normal to spatial bodies within a given system. 'Retrograde' derives from the Latin words retro, backwards, and gradus, step. In the Solar system, mostly everything rotates in the same sense: all major planets orbit the Sun counterclockwise as seen from the pole star (Polaris). Most planets spin in the same sense, including Earth. The same happens with the orbital motions of the...

Positional Astronomy -- Positional astronomy is the study of the positions of celestial objects. This is the oldest branch of astronomy and dates back to antiquity. Observations of celestial objects are important for religious and astrological purposes, as well as for timekeeping. Ancient structures associated with positional astronomy include: -- Chichn Itz -- The Medicine Wheel -- The Pyramids -- Stonehenge -- The Temple of the Sun The unaided human eye can...

Planetary Ring -- A planetary ring is a ring of dust and other small particles orbiting around a planet in a flat disc-shaped region. The most spectacular and famous planetary rings are those around Saturn, but all four of the solar system's gas giant planets (Jupiter, Saturn, Uranus, Neptune) possess ring systems of their own. The origin of planetary rings is not precisely known, but they are thought to be unstable and dissipate over the course of tens or hundreds of millions of...
