Radio astronomy in Russia

Historically, Russian radio astronomy
Radio astronomy
Radio astronomy is a subfield of astronomy that studies celestial objects at radio frequencies. The initial detection of radio waves from an astronomical object was made in the 1930s, when Karl Jansky observed radiation coming from the Milky Way. Subsequent observations have identified a number of...

, the Pushchino Radio Astronomy Observatory was developed within twenty years as part of the LPI Astro Space Center. It has become one of the largest radio astronomy observatories in Russia and in the world (2001). It was founded in April, 11th, 1956 under the purview of the Academy of Sciences of the USSR.

History of equipment in use

The Pushchino Radio Astronomy Observatory has four notable radio telescopes (RT 22), each with mirror
Mirror
A mirror is an object that reflects light or sound in a way that preserves much of its original quality prior to its contact with the mirror. Some mirrors also filter out some wavelengths, while preserving other wavelengths in the reflection...

Wavelength
In physics, the wavelength of a sinusoidal wave is the spatial period of the wave—the distance over which the wave's shape repeats.It is usually determined by considering the distance between consecutive corresponding points of the same phase, such as crests, troughs, or zero crossings, and is a...

. Added to the equipage is the DKR 1000, a wide-band radio telescope instrument, on-line in 1964, operating in in meter wavelength range. The DKR 1000 has arms that are 40 by 1000 meters. In 1973, another telescope was added to this set. The nomenclature is Large Phased Array with the designation BSA/LPI, operating in the meter wavelength range. The DKR 1000 and BSA/LPI, are currently the largest radio telescopes in the world, which operate in the meter range.

s and technicians to accomplish staff the several major departments and several labs of the observatory. These are combined with 80 other people who perform administrative duties, work shops, garage, and a staff of guards.
The departments and labs are designed to focus on scientific and technical aspects of observatory sciences.

The departments are as follows: Plasma astrophysics, Extragalactic radio astronomy, Pulsar physics, Space radio spectroscopy, and Pulsar astrometry. The laboratories are as follows: Radio astronomy equipment, Automation radio astronomy research, Computer engineering and information technology, and Radio telescopes of the meter wave-length range.
