If you want to indulge your inner space nerd, NASA has given you the next best thing: a searchable image and video library with copyright-free content. These public images can be used for whatever purpose you want. And there are a lot of those—over 140,000 images, videos, and audio files, in fact. The site will let you embed content on your own site and the images come in multiple resolutions for you to choose what you want to download. Searching is easy on the site. You can opt to just look for images, videos, audio files, or a mix of the three.
