Why does the appearance of the starry sky change throughout the year?

At different times of the year, different constellations can be observed in the evenings. Why is this happening?

The sun, as observations show, not only moves along with all the stars during the day, rising in the east and setting in the west, but also slowly moves among the stars in the opposite direction, i.e. from west to east, moving from constellation to constellation . We cannot observe the constellation in which the Sun is currently located, since it rises with the Sun and moves across the sky during the day, when the stars are not visible. The path along which the Sun moves among the stars throughout the year is called the ecliptic. It passes through twelve so-called zodiac constellations, each of which the Sun visits for approximately one month each year.

The annual motion of the Sun among the stars is apparent. In fact, the observer himself moves along with the Earth around the Sun, which is why it seems that the Sun moves from one constellation to another.

Why did the Dutch ship sail to Australia disguised as an island?

After being defeated by the Japanese in the Battle of the Java Sea, all remaining Allied ships were ordered to depart for Australia. The Dutch destroyer "Abraham Krijnssen" was on the way alone. In order to pass unnoticed, it was decided to disguise the ship as an island, for which the crew chopped tropical trees and branches and distributed them on the deck, and painted those protruding parts that could not be covered with foliage that looked like rocks. During the day, the destroyer remained motionless near the coast and only at night was removed from the anchor.

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. ... >>

Lights in the night sea 18.03.2010

Hundreds of thousands of migratory birds are killed every spring and autumn while crossing the North Sea.

The lights of numerous drilling platforms for oil and gas production disturb the orientation of the birds, leading them astray. And in those cases when a flare of associated gas burns on the platform, the birds can die in the fire. Physiologists have determined that birds are much less sensitive to blue and green light than they are to white, yellow, and red lights common to offshore platforms.

However, experiments on offshore drilling rigs by a Dutch oil company have shown that blue light has a sleep-inducing effect on night shift workers. Therefore, lighting engineers, in collaboration with physiologists and environmentalists, have developed special lamps and signal lights, the spectrum of which is shifted to the blue-green region.

As a result, the number of birds deviating towards the drilling platforms on which new lamps are installed decreased by 2-10 times as a result.
