You can browse NASA’s Image and Video Library online; you can also access it via NASA’s API. Through that interface, you can search by caption, keyword, location, photographer, year created, and other fields; in return, you get structured data on each media file. The library was launched two years ago, bringing together more than 140,000 images, videos, and audio files that had previously been spread across dozens of separate collections.
“Reading the Pictures analyzes and reports news and media images. In an ever more visual society, we seek to better understand the levels of meaning, the underlying story lines and the various agendas reflected in the more prominent news pictures of the day. We also publish and provide a careful look at original photojournalism and concerned photography.
