Final answer:
Auroras and lightning are two occurrences visible on Jupiter's night side, resulting from interaction with the planet's magnetic field and atmospheric conditions.
Step-by-step explanation:
The two phenomena that can be observed on Jupiter's night side are auroras and lightning. These occurrences are the result of Jupiter's strong magnetic field and turbulent atmosphere. Auroras on Jupiter are similar to Earth's northern and southern lights, created when charged particles from the solar wind interact with the planet's magnetic field. These particles excite gases in the upper atmosphere, causing them to emit light. Lightning on Jupiter is much more intense than on Earth, with the storms capable of producing lightning bolts that are significantly stronger than their Earthly counterparts.
Jupiter is well-known for its Great Red Spot and turbulent cloud patterns, as shown by enhanced images from spacecraft observations. The presence of dark and light bands along the equator is an example of its semi-permanent cloud features. Large impacts, such as those from comets or asteroids, also result in visible dark 'bruises' in Jupiter's stratosphere, indicating significant explosive forces. These features highlight the dynamic and ever-changing atmosphere of the gas giant.
