The discovery of this dramatic cooling also suggests that Neptune’s upper atmosphere can change significantly over time, despite the planet being more than 30 times farther from the Sun than Earth.

and that the ionosphere can change dramatically despite Neptune's great distance from the Sun. NASA says the next step will be to study Neptune across a full solar cycle, which lasts roughly 11 years.
