Kepler Stares at Neptune
During its K2 campaign, NASA’s Kepler spacecraft observed the eighth planet in our solar system, Neptune. Kepler detected small changes in Neptune’s brightness caused by the planet’s daily rotation, the movement of clouds, and even seismic waves from the sun itself. Originally designed to search for exoplanets (planets around other stars), Kepler’s observations of Neptune pave the way for future studies of weather and climate beyond our solar system.
