Have you ever needed a perfect photo of a nebula on which to Photoshop your cat? How about the ideal video of a rocket launch that can be sent as a GIF millions of times over?

Well, now NASA has you covered. The space agency just set up a searchable image and video library for every space-based need.

The best part: it's copyright free. You can download and use these images for whatever purpose you want, thanks to NASA's generous public images policy.

"NASA Image and Video Library allows users to search, discover and download a treasure trove of more than 140,000 NASA images, videos and audio files from across the agency’s many missions in aeronautics, astrophysics, Earth science, human spaceflight, and more," NASA said in a press release Tuesday. "Users now can embed content in their own sites and choose from multiple resolutions to download."

The archive is easy to use. Just search for your favorite planet or other cosmic object in the database and download it.

For example, this is the page we got searching for "Saturn" (which is clearly the best planet).

From there you can narrow your search down to just images, videos, audio or a mix of the three, and then pick out whatever image, video or audio file you may want.

So get out there and post, Photoshop and let your eyes pop at NASA's huge wealth of space porn.
