A bulge of elevated topography on the farside of the moon--known as the lunar farside highlands--has defied explanation for decades. But a new study led by researchers at the University of California, Santa Cruz, shows that the highlands may be the result of tidal forces acting early in the moon's history when its solid outer crust floated on an ocean of liquid rock. Ian Garrick-Bethell, an assistant professor of Earth and planetary sciences at UC Santa Cruz, found that the shape of the...

The frigid ice of Jupiter's moon Europa may be hiding more than a presumed ocean: it is likely the scene of some unexpectedly fast chemistry between water and sulfur dioxide at extremely cold temperatures. Although these molecules react easily as liquids-they are well-known ingredients of acid rain-Mark Loeffler and Reggie Hudson at NASA's Goddard Space Flight Center in Greenbelt, Md., now report that they react as ices with surprising speed and high yield at temperatures hundreds of degrees...

Been outside at midnight lately? There's something you really need to see. Jupiter is approaching Earth for the closest encounter between the two planets in more than a decade--and it is dazzling. The night of closest approach is Sept. 20-21st. This is also called "the night of opposition" because Jupiter will be opposite the sun, rising at sunset and soaring overhead at midnight. Among all denizens of the midnight sky, only the moon itself will be brighter. Earth-Jupiter encounters happen...

Amateur astronomers working with professional astronomers have spotted two fireballs lighting up Jupiter's atmosphere this summer, marking the first time Earth-based telescopes have captured relatively small objects burning up in the atmosphere of the giant planet. The two fireballs "“ which produced bright freckles on Jupiter that were visible through backyard telescopes "“ occurred on June 3, 2010, and August 20, 2010, respectively. A new paper that includes both pros and...

One might find that Jupiter's moon Europa to have extraterrestrial life after fossil-hunting on the icy surface. "A prospector sent there could possibly find extraterrestrial life within our lifetimes," planetary scientist Richard Greenberg at the University of Arizona's Lunar and Planetary Laboratory in Tucson told Space.com. A global ocean that may be about 100 miles deep envelops Europa.  An icy crust of unknown thickness overlies this ocean, although some estimates say that it is...

Detailed observations made by NASA's Hubble Space Telescope have found an answer to the flash of light seen June 3 on Jupiter. It came from a giant meteor burning up high above Jupiter's cloud tops. The space visitor did not plunge deep enough into the atmosphere to explode and leave behind any telltale cloud of debris, as seen in previous Jupiter collisions. Astronomers around the world knew that something must have hit the giant planet to unleash a flash of energy bright enough to be seen...

Jupiter's moon Io could be a potential target to look for extraterrestrial life. Io is the innermost of Jupiter's large moons and has the most volcanic activity in the solar system, with plumes of matter rising 186 miles above the surface. This activity is due to Jupiter's powerful gravitational pull, which causes Io's tormented solid crust to bulge up and down 328 feet or more, generating intense heat in Io due to friction. Io generally is considered a poor candidate for life because of...

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...

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...

Jupiter's Moon Himalia -- Himalia is Jupiter's tenth moon. Himalia is 110 miles (170 km) in diameter and orbits 7,000,000 miles (11,480,000 km) from Jupiter. Himalia has a mass of 9.5 x 1018kg. It orbits Jupiter in 250.5662 (Earth) days. Very little is known about Himalia. Himalia was discovered by C. Perrine in 1904. Orbital eccentricity is 0.15798. Orbital inclination is 27.63 degrees. Orbital period is 250.5662 days. Rotational period is 0.4 day. ----- NASA...
