These four Hubble images of Neptune were taken with the Wide Field Camera 3 on June 25-26, 2011, during the planet's 16-hour rotation. The snapshots were taken at roughly four-hour intervals, offering a full view of the planet. The images reveal high-altitude clouds in the northern and southern hemispheres. The clouds are composed of methane ice crystals.
