7. PULKOVO - RUSSIA'S MAIN OBSERVATORY
Two great observatories. Greenwich and Pulkovo, occupy a leading place among the observatories of the world.
Pulkovo is situated in a hilly area some kilometres from St. Peters-burg. You can't get to Pulkovo by train: when the railway was being built the astronomers specially asked that it should be kepi several kilometres away so that there should be no vibration to affect the sensitive instruments.
The work started in 1839, when the observatory was opened, and it is being continued now. This is the eternal work of astronomers to define the precise coordinates of the stars, to find out the exact "addresses" of heavenly bodies.
But today the scientists also conduct a time service, they study activity of the Sun, follow the flights of the Earth sputniks and calculate their orbits. The scientists of the observatory have made a valuable contribution to the study of the cosmos by observing artificial Earth satellites, man-made moons. The study of their orbits is very important for the flights of manned spaceships.
The Pulkovo observatory has a radioastronomy department equipped with modern apparatus. The big radio telescope installed there is stronger than any other telescope in the world. With the help of this powerful device the scientists of the Pulkovo observatory carry out a number of observations of Venus, Jupiter and ether planets. It is necessary that before flying to other planets scientists should get the greatest possible information about the heavenly bodies.
The astronomers have obtained extremely surprising results due to radioastronomical observation. By means of the radio telescope some remarkable studies of the surface of the Sun and of solar activity have been made and a method of investigating the movement of planets has been worked out.
Astronomical observation and cosmic experiments are spheres of scientific research in which broad co-operation of scientists of various countries would be most effective.
