Earlier this month new dating app Lumen launched, especially for over 50s. We spoke to co-founder Charly Lester about why you should try online dating in your fifties and sixties. By the time people are dating in their 50s, they often know what they are looking for in a partner. On Lumen, we encourage high quality profiles — everyone has at least 3 dating profile photos and a detailed bio so you can get a feel for people before you chat. Most of the people we met while we were building Lumen were more than happy to be upfront about what they wanted. They knew the type of relationship they were searching, and what kind of person attracted them.

Moon rock or lunar rock refers to rock that is found on the Earth's Moon. This includes lunar material collected during the course of human exploration of the Moon , and rock that has been ejected naturally from the Moon's surface and landed on the Earth as meteorites. Moon rocks on Earth come from four sources: those collected by six United States Apollo program crewed lunar landings from to ; those collected by three Soviet uncrewed Luna probes in the s; those collected by the Chinese Lunar Exploration Program 's uncrewed probes; and rocks that were ejected naturally from the lunar surface before falling to Earth as lunar meteorites.
In geology , pictures of rocks can be used to help you best determine which of the three major types a particular rock belongs to: igneous, sedimentary, or metamorphic. By comparing your rock sample with photographic examples, you can identify key characteristics such as how the rock was formed, what minerals and other materials it contains, and where the rock may have come from. Sooner or later, you're bound to encounter hard, rock-like substances that aren't rocks.
