Online since June 16th 1995, which probably explains the 1990s look of the site design, NASA's Astronomy Picture of the Day directs your eyes to the sky. Images are contributed by professional and amateur photographers and scientists. Each day's photo is accompanied by commentary from an expert. For example, the photo for May 11, 2015 shows the view of the sky over Hawaii's Mauna Kea volcano. Rollover annotations plot the locations of another volcano, Kilauea, the city of Hilo, the Milky Way, and other stars, constellations, and planets, directly onto the picture. The archive provides access to the last 20 years of images. Users can also follow Astronomy Picture of the Day on Facebook, Google Plus, or Twitter.
