. The radiant carrying in astrophysics is a carrying of electromagnetic radiance energy inside the space solids and among them, depending on the processes of its emetting spreading, scattering and absorbing. With the radiant carrying is connected the star constructions and their atmosphere. Back .
. The columns of the Sun. Sometimes in a good calm weather one may notice the light columns on the both sides of the Sun. These beams are reflected from vertically settled icy crystals, from which the cirrus clouds are formed. Some parts of columns are so bright that create the false suns. When it is strong frost these columns forcast the further temperature decreasing. Back .
. Jowell Persival (1855 - 1916) is an American astronomer. The main works concerns Mars’s investigations. The author of a hypothesis about artificial origin of Mar’s channels. In 1915 calculated the orbit and searched the above Neptune planet (Pluto was discovered in 1930). Back .
The divisity of galaxies. The galaxies are the giant (to hundred of billions of stars) star systems, where the stars are connected by gravitation laws with each other. ... Ther galaxy NGC 3031 . ... Each spiral galaxy has a core a flat disk where the spiral brancher locate. The stars and interstellar substance of spiral galaxies rotate around the core. ... In normal galaxies, such as our Galaxy, the great brightness of the core is accounted for the high concentration of stars. ...
... He was born in Cholmogory - a village where one generation before him saw the first Russian observatory and Lomonosov was able to use the angle gaude. ... But the atmosphere of Venus was so "rich" that no only during four last years of Lomonosov's life, but even two centuries after his death the astronomers didn't go far away from his investigations. 200 years exactly after "the star year" of Lomonosov in 1961 the Soviet spaceship - the first in the world went to Venus. ...

. The Lion. The Lion is situaded in the Zodiac between the Lobster andthe Virgin. It was known to shumers 5 thpusand years ago. The classic antique myth connected with the nemli lion killed by Heracle. And the stars position realy resembles a lying lion. His head is often called a sickle. Its stars are: Regul ( a of Lion, means "the tzar") and Denebola (means "the lion's tail"). Back .
The Swan. The Swan is a constellation in the form of a crist from the bright star in the Milky Way. The Babilonian called it "The Wood Bird", the arabs - "The Hen" and the Greeks caaled it the Swan. According to the myth Zevs in the image of the Swan tempted the wife of the Sparta tzar Leda and she bore a beautiful Elena and the celestial twins Castor and Polidevk. ... The Swan's bright star Deneb with Vega ( a of Lira) and Altair ( a of Eagle) forms an autumn-summer triangle. ...
... Pierr Simone Laplas.) For his bright intellect and an outstanding achievements in several sciences (astronomy, physics, mathematics) Laplas was called "a French Newton". He became a consistent follower of Newton and rut a task before himself of explaining the planets motion, the movement of their satellites, the ocean rising tides in the Earth and a complicated motion of the Moon. Laplas showed that the planets inequalities should be periodical (based on Newton's gravitation principal). ...
. Quantum clock (atomic clock) - the time measuring device containing quartz generator, controlled by the quantum frequency standard . Atoms play a role of pendulum. The frequency of atoms radiation while the atoms passing from one energy level to another regulates the quantum clock. This frequency is so stable (error 10^-11 - 10^-13) that quantum clocks allow to calculate the time more exactly, then astronomic methods. Back .
... They are known: active quantum frequency standards on the ammonia molecules beams (molecular generator) on the hydrogen generator (hydrogen generator) passive quantum frequency standards on the Cs atoms’ beam (cerium atomic beam tube); active and passive quantum frequency standards with an optical pumping of Cs or Rb steams. The stability of atomic beam quantum frequency standard achieves 10^ - 14. ...
