What is an asteroid?

Discoveries in the world of celestial bodies often resemble the discovery of a mystery. This is how asteroids were discovered. Scientists Titius and Bode at different times came to the conclusion that there must be some planet between Mars and Jupiter: there was some kind of gap in the distance between them. Therefore, several astronomers set about searching for this planet.

In 1801, a planet called Ceres was actually discovered at this place. But it was a very small planet, only 600 miles in diameter. Scientists decided that it could be just one of a group of minor planets, and the search continued.

After some time, three more planets were discovered, the largest of which was half the size of Ceres. Astronomers have decided that these planets are four fragments left after the explosion of some large planet. But after fifteen years of searching, one astronomer found another minor planet, and the hunt continued.

By 1890, 300 minor planets had been discovered, and between 1890 and 1927-2000 planets! These minor planets, mostly revolving in the space between Mars and Jupiter around the Sun, are called asteroids. It is estimated that there are about 100 of them, although many of them are too small to be easily detected. Some are only a few hundred meters across, and their total mass is only a small fraction of the mass of the Earth.

Regarding the appearance of asteroids, there is a hypothesis according to which they are fragments of an exploded satellite of Jupiter.

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. ... >>
