The inner walls of the crater have collapsed to form a series of step-like terraces, and a central peak is visible in the center of the image. Apollo 17 image courtesy of NASA.

Self-published authors could be paid as little as $0.006 per page read under new rules planned by Amazon. Writers who make their works available through Amazonâs Kindle Owners Lending Library, and a similar service called Kindle Unlimited, will no longer be paid per copy downloaded following a move announced last week.
