How does Halley’s comet

Halley’s comet is a bright, unique comet with a period of return to the Sun of about 75-76 years, which is visible even to the naked eye. The official astronomical name of this celestial body – 1P/Halley. For the comet Halley for the first time managed to determine the elliptical orbit and set the frequency of motion in the Solar system than did the Englishman Edmond Halley (1656-1742) the astronomer Royal, physicist, geophysicist, meteorologist, mathematician and demographer, in whose honor was named the comet.

In ancient times, people observed the appearance of Halley’s comet, but did not suspect that I see the same cosmic body. The first surviving written evidence about the emergence of a “heavenly sign” dates back to the year 249 BC, and since then the approaching comet was observed at least thirty times. The last observation of the comet Halley was possible in 1986, and the next is expected in the summer of 2061. I must admit that if an event of this magnitude is regarded as an auspicious time for space exploration, once the appearance of comets were regarded by the people as a “terrible sign” of the coming change, wars, government coups. For the most part, it’s because of “strong world” of those times. It is known that Genghis Khan saw a comet, regarded it as a personal message and a call for conquest of neighboring lands. The same happened in ancient China, and even at the dawn of our era in Europe. Continue reading

Changes in the Solar system

The solar system is entering a new era

From the sun to the Earth

Let’s start with the Sun. According to astrophysicists, since 1901 the intensity of the magnetic field lights grew by 230 percent. Recently, media reported about a powerful polar auroras in areas where such phenomena are usually not observed.

By the way, remember that the impact of magnetic storms on human health are talking fifteen or twenty years ago, no more. Maybe the impact just wasn’t so noticeable…

On mercury were discovered in polar ice and a powerful magnetic field. On Venus in less than 40 years on two and a half thousand per cent increase in the brightness of the Aurora. Also, there have been significant global changes of the atmosphere. Over the past decade more than 200 per cent increase in the brightness of the cloud of plasma surrounding Jupiter.

On Saturn for the last 30 years there has been a significant decrease in the rate in the Equatorial flows. In addition, increased x-ray radiation coming from the planet’s equator. Continue reading

Comet

Comets fascinate the human mind since ancient people first noticed the white tail streaking through the night starry sky. We remember the date when the comet flies past the Earth once a century or even less often and remember all our lives. In the middle ages in Europe, the appearance of comets was often linked to various natural disasters and diseases. In religion, these heavenly bodies also play an important role. For example, in the New Testament, the comet heralded the birth of Christ.

Astronomers find comets also interesting and fascinating space objects, because they are witnesses of great historical events and even carry evidence of them.

The comet is a relatively small object in our solar system, usually having a diameter of several kilometers. Sometimes called “dirty snowballs” because of their component substances. Usually comets are composed of the following four elements:

Dust

Ice (water, ammonia, methane, carbon dioxide)

Some organic materials (e.g., resin)

Rocky ground (optional) Continue reading

Comets of the centuries
In the fall of 2020, after Amateur astronomers Vitaly Nevsky and Artem Novichonok first observed the comet ISON, astronomers had expected that she would become a "Great comet" − a…
