Little was known about the effects of spaceflight on living creatures at the time of Laika's mission, and animal flights were viewed by engineers as a necessary precursor to human missions. The experiment, which monitored Laika's vital signs, aimed to prove that a living organism could survive being launched into orbit and continue to function under conditions of weakened gravity and increased radiation, providing scientists with some of the first data on the biological effects of spaceflight.

A natural diamond crystal
Diamond is a solid form of the element carbon with its atoms arranged in a crystal structure called diamond cubic. Diamond as a form of carbon is a tasteless, odourless, strong, brittle solid, colourless in pure form, a poor conductor of electricity, and insoluble in water. Another solid form of carbon known as graphite is the chemically stable form of carbon at room temperature and pressure, but diamond is metastable and converts to it at a negligible rate under those conditions. Diamond has the highest hardness and thermal conductivity of any natural material, properties that are used in major industrial applications such as cutting and polishing tools. They are also the reason that diamond anvil cells can subject materials to pressures found deep in the Earth.
Because the arrangement of atoms in diamond is extremely rigid, few types of impurity can contaminate it (two exceptions are boron and nitrogen). Small numbers of defects or impurities (about one per million of lattice atoms) can color a diamond blue (boron), yellow (nitrogen), brown (defects), green (radiation exposure), purple, pink, orange, or red. Diamond also has a very high refractive index and a relatively high optical dispersion. (Full article...)
Nadezhda Vasilievna Stasova (Russian: Надежда Васильевна Стасова; June 24 [O.S. June 12] 1822 – October 9 [O.S. September 27] 1895) was a Russian educator, activist, and feminist. Stasova was born into a noble and wealthy family; Tsar Alexander I of Russia was her godfather, and she received extensive private tutoring as a child. After experiencing family tragedy and personal disappointment as a young woman, she dedicated herself to women's education and economic empowerment. Alongside Anna Filosofova and Maria Trubnikova, Stasova was one of the earliest leaders of the Russian women's movement. Together, the three friends and allies were referred to as the "triumvirate".
The triumvirate founded and led several organizations designed to promote women's cultural and economic independence, including a publishing cooperative. Subsequently, the triumvirate pushed government officials to allow higher education for women, although continuing opposition meant that their successes were sometimes limited or reversed. Stasova eventually became the lead organizer of the Bestuzhev Courses in 1878, but a decade later was forced to resign under political pressure. In her final years, she continued her support for the cause of women's rights in Russia. Stasova died in 1895. (Full article...)
Due to the length of the front lines created by the German 1942 summer offensive, which had aimed at taking the Caucasus oil fields and the city of Stalingrad, German and other Axis forces were over-extended. The German decision to transfer several mechanized divisions from the Soviet Union to Western Europe exacerbated their situation. Furthermore, Axis units in the area were depleted by months of fighting, especially those which had taken part in the struggle for Stalingrad. The Germans could only count on the XXXXVIII Panzer Corps, which had the strength of a single panzer division, and the 29th Panzergrenadier Division as reserves to bolster their Romanian allies guarding the German Sixth Army's flanks. These Romanian armies lacked the heavy equipment to deal with Soviet armor. In contrast, the Red Army deployed over one million personnel for the offensive. Soviet troop movements were not without problems: concealing their build-up proved difficult, and Soviet units commonly arrived late due to logistical issues. Operation Uranus was first postponed by the Soviet high command (Stavka) from 8 to 17 November, then to 19 November. (Full article...)
Antarctica (/ænˈtɑːrktɪkə/ⓘ) is Earth's southernmost and least-populated continent. Situated almost entirely south of the Antarctic Circle and surrounded by the Southern Ocean (also known as the Antarctic Ocean), it contains the geographic South Pole. Antarctica is the fifth-largest continent, being about 40% larger than Europe, and has an area of 14,200,000 km2 (5,500,000 sq mi). Most of Antarctica is covered by the Antarctic ice sheet, with an average thickness of 1.9 km (1.2 mi).
Antarctica is, on average, the coldest, driest, and windiest of the continents, and it has the highest average elevation. It is mainly a polar desert, with annual precipitation of over 200 mm (8 in) along the coast and far less inland. About 70% of the world's freshwater reserves are frozen in Antarctica, which, if melted, would raise global sea levels by almost 60 metres (200 ft). Antarctica holds the record for the lowest measured temperature on Earth, −89.2 °C (−128.6 °F). The coastal regions can reach temperatures over 10 °C (50 °F) in the summer. Native species of animals include mites, nematodes, penguins, seals and tardigrades. Where vegetation occurs, it is mostly in the form of lichen or moss. (Full article...)
At the beginning of the Russo-Japanese War of 1904–1905, Petropavlovsk took part in the Battle of Port Arthur, where she was lightly damaged by Japanese shells and failed to score any hits in return. On 13 April 1904, the ship sank after striking one or more mines near Port Arthur, in northeast China. Casualties numbered 27 officers and 652 enlisted men, including Vice AdmiralStepan Makarov, the commander of the squadron, and the war artistVasily Vereshchagin. The arrival of the competent and aggressive Makarov after the Battle of Port Arthur had boosted Russian morale, which plummeted after his death. (Full article...)
In mid- to late-19th-century Russia, Pyotr Ilyich Tchaikovsky and a group of composers known as The Five had differing opinions as to whether Russian classical music should be composed following Western or native practices. Tchaikovsky wanted to write professional compositions of such quality that they would stand up to Western scrutiny and thus transcend national barriers, yet remain distinctively Russian in melody, rhythm and other compositional characteristics. The Five, made up of composers Mily Balakirev, Alexander Borodin, César Cui, Modest Mussorgsky, and Nikolai Rimsky-Korsakov, sought to produce a specifically Russian kind of art music, rather than one that imitated older European music or relied on European-style conservatory training. While Tchaikovsky himself used folk songs in some of his works, for the most part he tried to follow Western practices of composition, especially in terms of tonality and tonal progression. Also, unlike Tchaikovsky, none of The Five were academically trained in composition; in fact, their leader, Balakirev, considered academicism a threat to musical imagination. Along with critic Vladimir Stasov, who supported The Five, Balakirev attacked relentlessly both the Saint Petersburg Conservatory, from which Tchaikovsky had graduated, and its founder Anton Rubinstein, orally and in print.
As Tchaikovsky had become Rubinstein's best-known student, he was initially considered by association as a natural target for attack, especially as fodder for Cui's printed critical reviews. This attitude changed slightly when Rubinstein left the Saint Petersburg musical scene in 1867. In 1869 Tchaikovsky entered into a working relationship with Balakirev; the result was Tchaikovsky's first recognized masterpiece, the fantasy-overture Romeo and Juliet, a work which The Five wholeheartedly embraced. When Tchaikovsky wrote a positive review of Rimsky-Korsakov's Fantasy on Serbian Themes he was welcomed into the circle, despite concerns about the academic nature of his musical background. The finale of his Second Symphony, nicknamed the Little Russian, was also received enthusiastically by the group on its first performance in 1872. (Full article...)
Named for the siege of Sevastopol during the Crimean War, the ship was commissioned into the First Pacific Squadron of the Russian Pacific Fleet and was stationed at Port Arthur (today Lüshunkou District, Dalian, Liaoning, China), a Russian naval base acquired from China in 1898 as part of the Kwantung Leased Territory. One of the first ships to use Harvey nickel-steel armor and Popov radios, she displaced 11,854 long tons (12,044 t) at full load and was 369 feet (112.5 m) long overall, and mounted a main battery of four 12-inch (305 mm) guns in two twin turrets. She was laid down in May 1892, launched on 1 June 1895 and completed in 1899. Her sea trials lasted until 1900. (Full article...)

The Siberian accentor (Prunella montanella) is a small passerinebird that breeds in northern Russia from the Ural Mountains eastwards across Siberia. It is migratory, wintering in Korea and eastern China, with rare occurrences in western Europe and northwestern North America. Its typical breeding habitat is subarcticdeciduous forests and open coniferous woodland, often close to water, although it also occurs in mountains and sprucetaiga. It inhabits bushes and shrubs in winter, frequently near streams, but may also be found in dry grassland and woods.
The Siberian accentor has brown upperparts and wings, with bright chestnut streaking on its back and a greyish-brown rump and tail. The head has a dark brown crown and a long, wide pale yellow supercilium ("eyebrow"). All plumages are quite similar. The nest is an open cup in dense shrub or a tree into which the female lays four to six glossy deep blue-green eggs that hatch in about ten days. Adults and chicks feed mainly on insects, typically picked off the ground, but sometimes taken from vegetation. In winter, the accentors may also consume seeds or feed near human habitation.

The polar bear (Ursus maritimus) is a large bear native to the Arctic and nearby areas. It is closely related to the brown bear, and the two species can interbreed. The polar bear is the largest extant species of bear and land carnivore, with adult males weighing 300–800 kg (660–1,760 lb). The species is sexually dimorphic, as adult females are much smaller. The polar bear is white- or yellowish-furred with black skin and a thick layer of fat. It is more slender than the brown bear, with a narrower skull, longer neck and lower shoulder hump. Its teeth are sharper and more adapted to cutting meat. The paws are large and allow the bear to walk on ice and paddle in the water.
Polar bears are both terrestrial and pagophilic (ice-living) and are considered marine mammals because of their dependence on marine ecosystems. They prefer the annual sea ice but live on land when the ice melts in the summer. They are mostly carnivorous and specialized for preying on seals, particularly ringed seals. Such prey is typically taken by ambush; the bear may stalk its prey on the ice or in the water, but also will stay at a breathing hole or ice edge to wait for prey to swim by. The bear primarily feeds on the seal's energy-rich blubber. Other prey include walruses, beluga whales and some terrestrial animals. Polar bears are usually solitary but can be found in groups when on land. During the breeding season, male bears guard females and defend them from rivals. Mothers give birth to cubs in maternity dens during the winter. Young stay with their mother for up to two and a half years. (Full article...)
Serving in the Baltic Sea during World War I, Slava was the largest ship of the Russian Gulf of Riga Squadron that fought the German High Seas Fleet in the Battle of the Gulf of Riga in August 1915. She repeatedly bombarded German positions and troops for the rest of 1915 and during 1916. During the Battle of Moon Sound in 1917, Slava was badly damaged by the German dreadnoughtSMS König, significantly increasing her draft. The shallow channel made it impossible to escape and she was scuttled in the Moon Sound Strait between the island of Muhu (Moon) and the mainland. The Estoniansscrapped her during the 1930s.

The woolly mammoth (Mammuthus primigenius) is an extinct species of mammoth that lived from the Middle Pleistocene until its extinction in the Holocene epoch. It was one of the last in a line of mammoth species, beginning with the African Mammuthus subplanifrons in the early Pliocene. The woolly mammoth began to diverge from the steppe mammoth about 800,000 years ago in Siberia. Its closest extant relative is the Asian elephant. The Columbian mammoth (Mammuthus columbi) lived alongside the woolly mammoth in North America, and DNA studies show that the two hybridised with each other. Mammoth remains had long been known in Asia before they became known to Europeans. The origin of these remains was long a matter of debate and often explained as being remains of legendary creatures. The mammoth was identified as an extinct species of elephant by Georges Cuvier in 1796.
The appearance and behaviour of this species are among the best studied of any prehistoric animal because of the discovery of frozen carcasses in Siberia and North America, as well as skeletons, teeth, stomach contents, dung, and depiction from life in prehistoric cave paintings. The woolly mammoth was roughly the same size as modern African elephants. Males reached shoulder heights between 2.67 and 3.49 m (8 ft 9 in and 11 ft 5 in) and weighed between 3.9 and 8.2 t (3.8 and 8.1 long tons; 4.3 and 9.0 short tons). Females reached 2.3–2.6 m (7 ft 7 in – 8 ft 6 in) in shoulder heights and weighed between 2.8–4 t (2.8–3.9 long tons; 3.1–4.4 short tons). A newborn calf weighed about 90 kg (200 lb). The woolly mammoth was well adapted to the cold environments present during glacial periods, including the last ice age. It was covered in fur, with an outer covering of long guard hairs and a shorter undercoat. The colour of the coat varied from dark to light. The ears and tail were short to minimise frostbite and heat loss. It had long, curved tusks and four molars, which were replaced six times during the lifetime of an individual. Its behaviour was similar to that of modern elephants, and it used its tusks and trunk for manipulating objects, fighting, and foraging. The diet of the woolly mammoth was mainly grasses and sedges. Individuals could probably reach the age of 60. Its habitat was the mammoth steppe, which stretched across northern Eurasia and North America. (Full article...)
Charles Minard's Carte figurative (1869), which details the losses of men, the position of the army, and the freezing temperatures on Napoleon's disastrous 1812 invasion of Russia. Created in an effort to show the horrors of war, the graph "defies the pen of the historian in its brutal eloquence" and has been called the best statistical graphic ever drawn.

This photo of the Nilov Monastery on Stolobny Island in Tver Oblast, Russia, was taken by Sergey Prokudin-Gorsky in 1910 before the advent of colour photography. His process used a camera that took a series of monochrome pictures in rapid sequence, each through a different coloured filter. By projecting all three monochrome pictures using correctly coloured light, it was possible to reconstruct the original colour scene.
Although James Clerk Maxwell made the first color photograph in 1861, the results were far from realistic until Prokudin-Gorsky perfected the technique with a series of improvements around 1905. His process used a camera that took a series of monochrome pictures in rapid sequence, each through a different colored filter. Prokudin-Gorskii then went on to document much of the country of Russia, travelling by train in a specially equipped darkroomrailroad car.
Ivan Goremykin (1839–1917) was a Russian prime minister during World War I. A politician with archconservative views, after some time in the Ministry of Justice, he transferred to the Ministry of the Interior in 1891. He held the rank of prime minister from May to July 1906 and again from 1914 to 1916; during both terms his effectiveness was strongly limited by opposition from the State Duma. In the aftermath of the October Revolution, Goremykin was recognized as a member of the Tsarist government and killed by a street mob.
The Sukhoi Superjet 100 is a modern fly-by-wiretwin-engineregional jet with 8 to 108 passenger seats. Development began in 2000; the aircraft had its maiden flight on 19 May 2008 and entered commercial service on 21 April 2011. This aircraft is seen flying off the coast of Italy near Sanremo.
Saint Basil's Cathedral is a church in Red Square in Moscow, Russia. It was built from 1555 to 1561 on orders from Ivan the Terrible and commemorates the capture of Kazan and Astrakhan. The city's tallest building until the completion of the Ivan the Great Bell Tower in 1600, the original building contained eight side churches arranged around the ninth, central church of Intercession; the tenth church was erected in 1588 over the grave of venerated local saint Vasily (Basil). Although the Bolsheviks considered demolishing the church in the 1930s, it was spared. Since 1991 it has housed a branch of the State Historical Museum and hosted occasional church services.
Leo Tolstoy (1828–1910) was a Russian writer who is regarded as one of the world's greatest novelists. He is best known for War and Peace (1869) and Anna Karenina (1877), often cited as pinnacles of realist fiction. Born to an aristocratic family on 9 September [O.S. 28 August] 1828, Tolstoy was orphaned when he was young. He studied at Kazan University, but this was not a success, and he left university without completing his degree. During this time, he began to write and published his first novel, Childhood, in 1852. Tolstoy later served at the Siege of Sevastopol during the Crimean War, and was appalled by the number of deaths and left at the conclusion of the war. He spent the remainder of his life writing whilst also marrying and starting a family. In the 1870s he converted to a form of fervent Christian anarchism.
Alexei Leonov (1934–2019) was a Soviet cosmonaut, Air Force major general, writer, and artist. On 18 March 1965, he became the first human to conduct a spacewalk, exiting the capsule during the Voskhod 2 mission for 12 minutes and 9 seconds. At the end of the spacewalk, his spacesuit had inflated in the vacuum of space to the point that he had great difficulty re-entering the airlock, forcing him to open a valve to deflate his suit. His second trip into space took place ten years later, when he was commander of Soyuz 19, the Soviet half of the 1975 Apollo–Soyuz Test Project, the first joint space mission between the Soviet Union and the United States. The crater Leonov on the far side of the Moon is named after him.
This picture shows Leonov photographed in 1974, wearing a lapel pin with a version of the emblem for the Apollo–Soyuz Test Project, which was then in development.
The Krestovsky Stadium is the home ground of FC Zenit Saint Petersburg.

It was opened in 2017 as a venue for the 2017 FIFA Confederations Cup, and hosted the final, in which Germany beat Chile 1–0. It was one of the venues for the 2018 FIFA World Cup the following year. Among other features, it has a retractable roof, and is equipped with a video-surveillance and identification system, as well as security-alarm, fire-alarm and robotic fire-extinguishing systems. The stadium's seating capacity is 67,800.
Fyodor Dostoevsky (1821–81; depicted in 1872) was a Russian novelist, short story writer, essayist and philosopher. After publishing his first novel, Poor Folk, at age 25, Dostoyevsky wrote (among others) eleven novels, three novellas, and seventeen short novels, including Crime and Punishment (1866), The Idiot (1869), and The Brothers Karamazov (1880).

Khrushchev was born in 1894 in a village in western Russia. He was employed as a metal worker during his youth, and he was a political commissar during the Russian Civil War. Under the sponsorship of Lazar Kaganovich, Khrushchev worked his way up the Soviet hierarchy. He originally supported Stalin's purges and approved thousands of arrests. In 1938, Stalin sent him to govern the Ukrainian SSR, and he continued the purges there. During what was known as the Great Patriotic War, Khrushchev was again a commissar, serving as an intermediary between Stalin and his generals. Khrushchev was present at the defense of Stalingrad, a fact he took great pride in. After the war, he returned to Ukraine before being recalled to Moscow as one of Stalin's close advisers.
