Two great observatories, Greenwich and Pulkovo, occupy a leading place
among the observatories of the world. Some scientists call Pulkovo the
astronomical capital of the world.

Pulkovo is situated in a hilly area some kilometers from Leningrad. You
can't get to Pulkovo by train – when the railway was being built the
astronomers specially asked that it should be kept several kilometers
away so that there should be no vibration to affect the sensitive

The work started in 1839, when the observatory was opened, is being
continued now. This is the eternal work of astronomers – to define the
precise co-ordinates 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 Soviet
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 radio-astronomy 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
devise the scientists of the Pulkovo observatory carry out a number of
observations of Venus, Jupiter and other 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
radio- astronomical 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. Soviet scientists, workers and
technicians have produced and launched space rockets in the direction of
the Moon, Venus and Mars and are fulfilling the noble dreams of mankind.
May there be peaceful ships flying the space routes and may they serve
the interests of all the people of the world!
