I took this photo of Jupiter and it's astonishing moons in late November last year through my Celestron 5" telescope! Jupiter is the largest planet of the Solar system, and is almost entirely made up of gas. In fact, if you were to suddenly appear on Jupiter, you would sink through the layers of gas until you reached the center of the planet, being crushed by extreme pressures! Europa is my favorite moon of Jupiter. An intriguing planet which harbors oceans of liquid water, and quite possibly, life.
