Temperature: Europa's surface temperature at the equator never rises above minus 260 degrees Fahrenheit (minus 160 degrees Celsius). At the poles of the moon, the temperature never rises above minus 370 degrees Fahrenheit (minus 220 degrees Celsius).
Europa Moon - Surface Features: In this picture, a number of red brown lines and circles are visible. The lines, which are cracks in the surface caused by tectonic stress, are known as lineae (from the Latin for line) while the circles, which are probably areas of melted then refrozen ice, are known as lenticulae (from the Latin for freckles).
As per NASA, Europa may be more Earth-like than we imagined. Scientists see signs of plate tectonics.
