Latest Moons of Jupiter Stories
NASA's voyage to Europa might be our last chance to find alien life on the Jovial moon.
New images captured by the Hubble Space Telescope depict a rare event known as a tri-moon conjunction, in which three of Jupiter’s largest moons are passing across the banded face of the gas-giant at the same time, NASA officials announced on Thursday.
WASHINGTON, Feb. 4, 2015 /PRNewswire-USNewswire/ -- NASA's New Horizons spacecraft returned its first new images of Pluto on Wednesday, as the probe closes in on the dwarf planet.
Known as a "triple shadow transit," three of Jupiter’s moons will simultaneously cast shadows onto the cloudy planet on Saturday (January 24th, 2014). Get ready!
WASHINGTON, Jan. 15, 2015 /PRNewswire-USNewswire/ -- NASA's New Horizons spacecraft recently began its long-awaited, historic encounter with Pluto.
The scientific community was a-buzz in late 2013, when NASA researchers reported that the Hubble Space Telescope had detected 120-mile high vapor plumes emanating from the south pole of Jupiter’s moon Europa.
The European Space Agency's JUICE (JUpiter ICy moons Explorer) mission has been given the green light to proceed to the next stage of development.
Scientists have produced a new version of what is perhaps NASA's best view of Jupiter's ice-covered moon, Europa.
Satelles, a division of iKare Corporation, is pleased to announce today that Richard Perry has joined the company's board of directors. REDWOOD CITY, Calif., Oct.
WASHINGTON, Sept. 8, 2014 /PRNewswire-USNewswire/ -- Scientists have found evidence of plate tectonics on Jupiter's moon Europa.
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...
