What are lunar craters?

Craters are depressions on the surface of a cosmic body that have rounded outlines. The size of the craters is from 1 meter to 250 kilometers. Large and medium-sized craters on the Moon have been known since the first telescopic observations of this celestial body. They bear the names of famous scientists: Aristotle, Herodotus, Hipparchus, Copernicus, Kepler, etc.

Many large craters are surrounded by gently sloping ridges and have a flat bottom, in the middle of which a central hill rises. Others are in the form of funnels, which are formed during explosions. Numerous small craters cover the entire lunar surface and even the bottom and ramparts of large craters. Craters, even of an unusual shape, were formed when meteorites fell on the surface of the Moon.

Meteorites also owe their origin to the long bright rays that radiate from some large craters (for example, from the craters Tycho, Copernicus, Kepler) over distances of several hundred and even thousands of kilometers. They are chains of small craters covered with fine-grained matter that strongly scatters sunlight.

 Random interesting fact from the Great Encyclopedia:

Where is the lake located, which every year hides a whole park under water for a while?

Lake Gruner is located in Austria, surrounded by mountains on all sides. In winter, the depth of the lake is 1-2 meters, and the area around it serves as a park. But in spring, snow begins to melt in the mountains, feeding the lake with new water, and by May its depth increases to 12 meters. Under the surface of the lake there are trees, paths, benches, which, combined with crystal clear water, makes it a popular place for diving at this time.

Artificial leather for touch emulation 15.04.2024

In a modern technology world where distance is becoming increasingly commonplace, maintaining connection and a sense of closeness is important. Recent developments in artificial skin by German scientists from Saarland University represent a new era in virtual interactions. German researchers from Saarland University have developed ultra-thin films that can transmit the sensation of touch over a distance. This cutting-edge technology provides new opportunities for virtual communication, especially for those who find themselves far from their loved ones. The ultra-thin films developed by the researchers, just 50 micrometers thick, can be integrated into textiles and worn like a second skin. These films act as sensors that recognize tactile signals from mom or dad, and as actuators that transmit these movements to the baby. Parents' touch to the fabric activates sensors that react to pressure and deform the ultra-thin film. This ... >>

The attractiveness of caring men 14.04.2024

The stereotype that women prefer "bad boys" has long been widespread. However, recent research conducted by British scientists from Monash University offers a new perspective on this issue. They looked at how women responded to men's emotional responsibility and willingness to help others. The study's findings could change our understanding of what makes men attractive to women. A study conducted by scientists from Monash University leads to new findings about men's attractiveness to women. In the experiment, women were shown photographs of men with brief stories about their behavior in various situations, including their reaction to an encounter with a homeless person. Some of the men ignored the homeless man, while others helped him, such as buying him food. A study found that men who showed empathy and kindness were more attractive to women compared to men who showed empathy and kindness. ... >>
