Kardashev, Nikolai Semenovich (1932-)
Russian astrophysicist and deputy director of the Space Research Institute
of the Academy of Sciences, Moscow, who conducted the first Soviet search
for intelligent extraterrestrial signals in 1963. A graduate of Moscow University
(1955), Kardaschev studied under Shklovskii
at the Sternberg Astronomical Institute,
from where he obtained his Ph.D. in 1962. The following year he carried
out the pioneering Soviet effort in SETI,
examining quasar CTA-102. An early advocate
of the idea that some alien races may be billions of years ahead of us,
he proposed a classification for such supercivilizations (see
Kardashev civilizations) and recommended that searches for them concentrate
on the infrared and millimeter-wave ranges
of the spectrum, rather than the centimeter-wave range.1 In 1963,
Kardashev organized a SETI research group at the Sternberg Institute and
initiated arrangements for the first All-Union Meeting on extraterrestrial
civilizations (see Byurakan SETI conferences).
