The journal covers research on all aspects of astronomy and astrophysics, including high energy astrophysics, cosmology, space astronomy, theoretical astrophysics, radio astronomy, extra galactic astronomy, stellar astronomy, and investigation of the Solar system. ''Pis’ma v Astronomicheskii Zhurnal'' is translated in its English version by MAIK Nauka/Interperiodica, which is also the official publisher. However, beginning in 2006 access and distribution outside of Russia is made through Springer Science+Business Media. Both English and Russian versions are published simultaneously.

4236 Lidov
4 (four) is a number, numeral and digit. It is the natural number following 3 and preceding 5. It is the smallest semiprime and composite number, and is considered unlucky in many East Asian cultures. In mathematics Four is the smallest composite number, its proper divisors being and . Four is the sum and product of two with itself: 2 + 2 = 4 = 2 x 2, the only number b such that a + a = b = a x a, which also makes four the smallest squared prime number p^. In Knuth's up-arrow notation, , and so forth, for any number of up arrows. By consequence, four is the only square one more than a prime number, specifically three. The sum of the first four prime numbers two + three + five + seven is the only sum of four consecutive prime numbers that yields an odd prime number, seventeen, which is the fourth super-prime. Four lies between the first proper pair of twin primes, three and five, which are the first two Fermat primes, like seventeen, which is the third. On the other han ...

Soviet Space Program
The Soviet space program (russian: Космическая программа СССР, Kosmicheskaya programma SSSR) was the national space program of the former Union of Soviet Socialist Republics (USSR), active from 1955 until the dissolution of the Soviet Union in 1991. Soviet investigations in rocketry began with the formation of a research laboratory in 1921, but these efforts were hampered by the devastating war with Germany. Competing in the Space Race with the United States and later with the European Union and China, the Soviet program was notable in setting many records in space exploration, including the first intercontinental missile that launched the first satellite and sent the first animal into Earth orbit in 1957, and placed the first human in space in 1961. In addition, the Soviet program also saw the first woman in space in 1963 and a cosmonaut performing the first spacewalk in 1965. Other milestones included computerized robotic missions exploring t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
