This is a montage of New Horizons images of Jupiter and its volcanic moon Io, taken during the spacecraft’s Jupiter flyby . The image was released in Oct. 2007. (Image credit: NASA/Johns Hopkins University Applied Physics Laboratory/Southwest Research Institute) Jupiter's fifth moon, Io, is the most volcanically active body in the solar system. Plumes of sulfur spew upward as high as 190 miles (300 kilometers). The surface of Io is splotched with lava lakes and floodplains of liquid rock. Astronomers have mapped about 150 volcanoes on the moon, some of which blast lava 250 miles (400 km) out into space. There are volcanoes all over Io's surface, and as scientists perform observations they still occasionally see new hotspots pop up. For example, NASA's Juno spacecraft, which is currently orbiting Jupiter, found a possible new hotspot on Io on Dec. 16, 2017. Io by the numbers Age: Io is about 4.5 billion years old, about the same age as Jupiter. Distan...

It has been very interesting to explore new planets and stars, If we talk about Europa, It is so smaller than Earth. It's actually a Moon of Jupiter. there is no evidence that life exists on Europa, but Europa has emerged as one of the most likely locations in the Solar System for potential habitability. Life could exist in its under-ice ocean, perhaps in an environment similar to Earth's deep-ocean hydrothermal vents. The Chemical Elements of life might be under the surface of Europa, because The surface of Europa was destroyed by Jupiter's Radiation, But that radiation might have helped life to live under the surface of Europa. Europa's most of the surface is made of Ice and we have a strong evidence that there is a deep ocean under the surface of Europa. The scientists have said that there are strong possibilities of life on Europa.

Callisto has an exceptionally slim environment, is thought to contain a sea, and is in this way one more conceivable competitor for life past Earth. Notwithstanding, its separation from Jupiter implies it doesn't experience a particularly solid gravitational draw, so it's not as geographically dynamic as the other Galilean moons of Io and Europa. Albeit some have conjectured that life might be conceivable inside the air of Jupiter itself, more probable competitors are the four frigid Galilean moons around it. Every one of the four moons are amazingly cold, and all have slim environments. In any case, they are for the most part enticing possibilities for discovering life past Earth.
