Get lost in the NASA Image Archive. You can spend hours viewing the images on this site.
“NASA Images is a service of Internet Archive ( www.archive.org ), a non-profit library, to offer public access to NASA’s images, videos and audio collections. NASA Images is constantly growing with the addition of current media from NASA as well as newly digitized media from the archives of the NASA Centers.
The goal of NASA Images is to increase our understanding of the earth, our solar system and the universe beyond in order to benefit humanity.” Quoted frrom NASA Images.
This is a detail of the larger image, belive it or not. How is it done?
The Gigapan mount above, read on from the Gigapan website.
We are beta-testing prototypes of the Gigapan robotic mount, which attaches to your small digital camera to create a fast and easy-to-use high-resolution panorama capture device. We are growing the beta process and are negotiating concerning general release and sales of the Gigapan camera. You will be able to purchase these low-cost robotic mounts and take several hundred or thousand images at a time to create panoramas with one billion pixels and more.
You don’t need specialized GigaPan hardware to take your own panoramas. If you have lots of patience, a high-quality digital camera, and a good tripod (or very steady hand!) you can take hundreds or thousands of overlapping, zoomed-in pictures for a gigapixel-scale panorama, then use off-the-shelf stitching software to combine the images into one very high-resolution panorama for upload.
