David Levi: a Guide to the starry sky
Comets, the “tailed stars”. From time to time in the starry sky appear of the comet, which got its name from the Greek word “kometes” “tailed”. Often, the comet took over some otherworldly forces and beings, in the Christian era, they attributed divine the meaning and was considered God’s messengers – angels. The Slavs we, the Germans existed beliefs – seeing a shooting star to pray, convinced that any desire expressed at the short time, while star rolling, will come true. Comet was brought in to the stars also called tailed stars or sirkali with a broom, the Germans schweifstern, haarstern (hairy star) and pfauenschwanz (peacock tail) ; Lithuanian songs mention the comet, as old men with long beards, whose appearance portends something extraordinary. Thus, on the basis of different similes light strip cast by the nucleus of the comet, the language gives it a tail, a broom or a beard. Rare comets made him unusual for people to connect with these tailed stars the idea of divine predvidenie of future troubles for their sins and the mortal call to repentance. Interesting review, made by Patriarch Nikon in-out, in 1664 at the monastery of the resurrection. Sitting at night in the sleigh, he began to atrasti the dust from your feet, remembering prominent Evangelical words: “the IDA also if you do not accept, basedfrom the hail and the dust stuck to your feet, shake off as a testimony against nya”. Streltsy Colonel, dressed escort of Nikon, said: we are the ashes we’ll sweep! – Let razmyat the Lord God you trade only a divine broom, who is on many days! – objected Nikon, pointing to the burning in the sky the comet. Humboldt in his “Cosmos” points to the poetic view, which in ancient times was connected with the comets: they saw shaggy stars and flaming swords.
Comets have the appearance of a small hazy spot with a light tail, and sometimes even several. Inside misty spot, called the head of the comet, sometimes shows a relatively bright nucleus, like a star. In fact the nucleus of the comet is a big lump of frozen gases, within which solid particles and a variety of sizes, from fine dust to large rocky masses. Continue reading
Hello dear readers! In this post we will talk about the structure of the Solar system. I think you just need to know where in the Universe is our planet, and what else is in our Solar system besides planets.
Our planet Earth is part of the system of planets and other celestial bodies that rotate around a star called the Sun. The solar system is one of many such systems in the Universe .
The solar system is a system of cosmic bodies, which in addition to the Central luminary – the Sun, nine major planets, their satellites, the numerous small planets, comets, space dust and small meteoroids that move in the field pre-emption gravitational action of the Sun.
In the middle of the sixteenth century was uncovered the General structure of the Solar system Polish astronomer Nicholas Copernicus. He disproved the idea that the Earth is the center of the Universe and substantiate the presentation of the motion of planets around the Sun. This model of the Solar system was called the heliocentric. Continue reading
“Transition to transformation”
Humanity seems to have stayed in their home Solar system. Of his burning desire to go to other stars, scientists said at a scientific conference, held in October in Houston (Texas, USA ). Experts discussed the most grandiose project of the century – “Centennial spaceship” (“100-Year Starship”, or 100YSS ).
– Despite all the technological advances of humans, in the field of space exploration we’re on the level of cave people, – assured the leader of 100YSS Mae Jamison. All we did was hang a station in earth orbit, where just sometimes come to live people. The main task of space exploration in the long term should be the creation of colonies, which can live people.
The project was launched by the defense advanced Agency research projects U.S. Department of defense (DARPA) to explore all possibilities of distant travel. Help them specialists from the Research center named Ames, one of the main research laboratories of NASA. Scientists believe that their dream will come true within the next 100 years. Continue reading
