Three-dimensional clouds over the Philippine Sea, photographed by an astronaut on the International Space Station on June 25, 2016. The sea is lit by late afternoon sunlight. Two large thunderclouds on the lower right have long tails, also known as anvils, that stretch nearly 100 kilometers to the south. The northern Philippine islands (top right) are mostly obscured by clouds. This image has been cropped and enhanced to improve contrast, and lens artifacts have been removed.
