Carme: Discovered on July 30, 1938, by Seth Barnes Nicholson during observations made with the 100-inch (2.5 m) Hooker telescope at the Mount Wilson Observatory in California. The composition of this material is not yet entirely clear, but theories suggest that it is largely molten sulfur and its compounds (which would account for the varied coloring) or silicate rock (which would better account for the apparent temperatures, which may be too hot to be sulfur). We love your photos and welcome your news tips. in Enceladus and possibly other icy ocean worlds in the solar system beyond Jupiter," Glein said. New Juno findings provide a fuller picture of Jupiters colorful atmospheric features, and offer clues about what's below the clouds. Since then its been on an elliptical orbit so it can cruise close to Jupiters cloud tops, though a major focus of its current extended mission are the large Galilean moons of JupiterGanymede, Europa, Callisto and Io. Jupiter's moons: Names, number and exploration | Space Although Io always points the same side toward Jupiter in its orbit around the giant planet, the large moons Europa and Ganymede perturb Io's orbit into an irregularly elliptical one. NASA Administrator Bill Nelson laid out the path forward for early Artemis missions that will pave the way for lunar surface missions. Juno is only the second spacecraft to orbit Jupiter and is busy investigating its composition, atmosphere, gravity and magnetic field. Astronomers expect to find more moons. Those ejected particles, clues to the subsurface ocean, were analyzed by instruments on board the Cassini space mission. Such worlds include the icy satellites of the giant planets, such as Europa, Titan and Enceladus, as well as more distant bodies like Pluto. With a slight ellipsoid in shape, this moon has an orbital eccentricity of 0.0041 and rotates synchronously with its orbital period ensuring that one side always facing Jupiter. Critical analysis reveals that the volcanic plumes and lava flows are responsible for the surface color of different shades of yellow, red, white, black, and green or, as people call it rotten orange or pizza colors. Io is in a constant gravitational tug-of-war with Jupiter and the other big moons, so much so that it actually changes shape during its 42-hour orbit.
