Why do comets disappear?

In addition to the planets and their satellites, the solar system also includes comets. Comets move in certain paths, called orbits, around the Sun at a certain speed. The orbits of many comets are highly elongated and resemble an elongated thick cigar in shape. Comets orbit past nearby stars. It takes thousands of years for a comet to complete its entire orbit. Therefore, it seems that they disappear, but in fact they simply go out of sight. Comets are strongly influenced by the gravitational forces of the planets.

Some comets deviate from their orbits under the influence of these forces, their orbit becomes shorter. Jupiter, for example, has collected a large number of comets, each of which revolves around the Sun with an orbital period of 6 years. Comets that appear with a certain regularity are called periodic comets.

Do comets disappear forever? Some disappear. In 1826, astronomer Wilhelm von Biela discovered one of these "disappeared comets". She appeared several times, and each time she was observed by hundreds of astronomers. Then in 1846, the comet split in two, forming two comets. Then both of these parts of Beal's comet disintegrated into a large number of small ones. It is believed that these fragments formed a meteor shower that appears in the sky at the end of November. The history of Beale's Comet shows that some comets do die; they break up, fall out of their orbits and become meteoritic dust.

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. ... >>
