Kaluga Oblast in the context of "Slavic neopaganism"

The Slavic Native Faith, commonly known as Rodnovery and sometimes as Slavic Neopaganism, is a modern Pagan religion. Classified as a new religious movement, its practitioners hearken back to the historical belief systems of the Slavic peoples of Central and Eastern Europe, though the movement is inclusive of external influences and hosts a variety of currents. "Rodnovery" is a widely accepted self-descriptor within the community, although there are Rodnover organisations which further characterise the religion as Vedism, Orthodoxy, and Old Belief.

Many Rodnovers regard their religion as a faithful continuation of the ancient beliefs that survived as a folk religion or a conscious "double belief" following the Christianisation of the Slavs in the Middle Ages. Rodnovery draws upon surviving historical and archaeological sources and folk religion, often integrating them with non-Slavic sources such as Hinduism (because they are believed to come from the same Proto-Indo-European source). Rodnover theology and cosmology may be described as henotheism and polytheism—worship of the supreme God of the universe and worship of the multiple gods, the ancestors and the spirits of nature who are identified in Slavic culture. Adherents of Rodnovery usually meet in groups in order to perform religious ceremonies. These ceremonies typically entail the invocation of gods, the offering of sacrifices and the pouring of libations, dances and communal meals.

The Oka (UK: /ˈɒkə/, US: /ˈoʊkə/; Russian: Ока IPA: [ɐˈka]) is a river in central Russia, the largest right tributary of the Volga. It flows through the regions of Oryol, Tula, Kaluga, Moscow, Ryazan, Vladimir and Nizhny Novgorod and is navigable over a large part of its total length, as far upstream as the town of Kaluga. Its length is 1,500 km (930 mi) and its catchment area 245,000 km (95,000 sq mi). The Russian capital Moscow sits on one of the Oka's tributaries—the Moskva, from which the capital's name is thought to be derived.

Kaluga (Russian: Калу́га, IPA: [kɐˈɫuɡə] ) is a city and the administrative center of Kaluga Oblast, Russia. It stands on the Oka River 150 kilometers (93 mi) southwest of Moscow. Its population was 337,058 at the 2021 census.

Kaluga's most famous resident, the space travel pioneer Konstantin Tsiolkovsky, worked there as a school teacher from 1892 to 1935. The Tsiolkovsky State Museum of the History of Cosmonautics in Kaluga is dedicated to his theoretical achievements and to their practical implementations for modern space research, hence the motto on the city's coat of arms: Колыбель Космонавтики, Kolybélʹ kosmonávtiki ("The Cradle of Space-Exploration").

Obninsk Nuclear Power Plant (Russian: Обнинская АЭС, romanized: Obninskaya AES; pronunciation) was built in the "Science City" of Obninsk, Kaluga Oblast, about 110 km (68 mi) southwest of Moscow, Soviet Union. Connected to the power grid in June 1954, Obninsk was the first grid-connected nuclear power plant in the world, i.e. the first nuclear reactor that produced electricity industrially, albeit at small scale. It was located at the Institute of Physics and Power Engineering. The plant is also known as APS-1 Obninsk (Atomic Power Station 1 Obninsk). It remained in operation between 1954 and 2002. Its production of electricity for the grid ceased in 2002; thereafter it functioned as a research and isotope production plant only.

According to Lev Kotchetkov, who was there at the time: "Although utilisation of generated heat was going on, and production of isotopes was even enhanced, the main task was to carry out experimental studies on 17 test loops installed in the reactor." The technology perfected in the Obninsk pilot plant was later employed on a much larger scale in the RBMK reactors.

Moscow Oblast (Russian: Московская область, romanized: Moskovskaya oblastʹ, IPA: [mɐˈskofskəjə ˈobləsʲtʲ], informally known as Подмосковье, Podmoskovye, IPA: [pədmɐˈskovʲjə]) is a federal subject of Russia (an oblast). With a population of 8,524,665 (2021 Census) living in an area of 44,300 square kilometers (17,100 sq mi), it is one of the most densely populated regions in the country and is the second most populous federal subject. The oblast has no official administrative center; its public authorities are located in Moscow and Krasnogorsk (the Moscow Oblast Duma and the local government), and also across other locations in the oblast.

Located in European Russia between latitudes 54° and 57° N and longitudes 35° and 41° E, Moscow Oblast borders Tver Oblast in the northwest, Yaroslavl Oblast in the north, Vladimir Oblast in the northeast and east, Ryazan Oblast in the southeast, Tula Oblast in the south, Kaluga Oblast in the southwest, and Smolensk Oblast in the west. The oblast mostly surrounds the federal city of Moscow, which is not part of the oblast, but rather a separate federal subject in its own right. The oblast is highly industrialized, with the major industries being metallurgy, oil refining, and mechanical engineering, along with the food, energy, and chemical industries.

The Protva (Russian: Протва) is a river in the Moscow and Kaluga oblasts in Russia. It is a left tributary of the Oka. It is 282 kilometres (175 mi) long, and has a drainage basin of 4,620 square kilometres (1,780 sq mi). The area of its basin is 4,620 square kilometres (1,780 sq mi). The Protva freezes up in early December and stays icebound until early April. Its main tributary is the Luzha. The towns of Vereya, Borovsk, Protvino and Obninsk are located on the shores of the Protva.
