Jupiter always appears as a full disk or a nearly full disk when viewed from Earth because it is much larger and closer to the Sun than the Earth. This means that the angle between the Sun, Jupiter, and Earth is such that we always see most of Jupiter illuminated. A crescent phase, where only a portion of Jupiter is illuminated, is not possible due to this alignment.
You can see Jupiter's moons any night whenever you can see Jupiter, with the possible exception of times when the Moon is close to it. Just now (2014) Jupiter is mostly visible in midwinter.
A crescent Jupiter cannot be seen from Earth because Jupiter always presents a full disk or nearly full disk due to its size and distance from the sun. Unlike the crescent phases seen in inner planets like Venus and Mercury as they orbit the sun, Jupiter's position relative to the sun and Earth means its illuminated side is always facing our viewpoint.
Jupiter is not known as the blue planet because it is not blue. See the link for a picture of Jupiter.
It was only during spacecraft missions to Jupiter that crescent views of the planet were obtained. A small telescope will usually show Jupiter's four Galilean moons and the prominent cloud belts across Jupiter's atmosphere. A large telescope will show Jupiter's Great Red Spot when it faces the Earth.
no, it is highly impossible to see a crescent Jupiter.

Jupiter has a moon called Io. It has active volcanoes made from sulfur. Sometimes this material gets into the orbit of Jupiter and forms a donut-shaped ring. Jupiter's rings are very hard to see and nowhere as spectacular as Saturn's.
yes you can see Jupiter from venus
The crescent phase.
Jupiter's moon Io is sometimes referred to as the "Pizza Moon".
Mars is closest to Jupiter on average but Saturn is sometimes closer when it is on the same side of the sun as Jupiter.
Ganymede isn't "hidden"; it is just too close to Jupiter to see it without a telescope. When Galileo pointed his telescope at Jupiter, he was astonished to find four other small things that appeared to stay close to Jupiter. They were named Ganymede, Callisto, Europa and Io, and are sometimes called the "Galilean moons". Day by day, you can see them orbiting Jupiter, their positions different each day.
Neptune, Uranus, Saturn and Jupiter are never seen as crescents from Earth. They are always "almost full".
