Larger craters can have terraces, central peaks, and multiple rings. Copernicus is a large crater (93 kilometers or 60 miles wide) on the Moon. 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.
Kindle Unlimited: Worth $10 a month, but needs more books. Iâm not ashamed to admit just how excited I was when Amazon announced Unlimited this summer. I read a lot. Perhaps an unhealthy amount â at home, on the train, at restaurants and coffee shops and at the gym. I burn through books like the dystopian government in Fahrenheit 451.
