A map showing the territorial evolution of Canada. At Confederation in 1867, four provinces (Ontario, Quebec, New Brunswick, and Nova Scotia) were established from three British colonies. This nascent country continued to accrete new provinces and territories, including Manitoba in 1870, British Columbia in 1871, Prince Edward Island in 1873, and Alberta and Saskatchewan in 1905; previously established provinces also expanded their borders. The most recent province to be added was Newfoundland in 1949; it has since been renamed Newfoundland and Labrador.

Since the cession of the Northwest Territories to Canada in 1870 and 1880, sections of the territory have been converted several times into new territories (Yukon in 1898, Nunavut in 1999) and provinces (Alberta and Saskatchewan), and transferred to expand existing provinces.Animation: Golbez

One of the first animals to be domesticated, sheep are likely descended from the wild mouflon of Europe and Asia. They are raised for their fleece, meat, and milk.Photograph: Keith Weller/Agricultural Research Service

The Apollo–Soyuz Test Project was the first joint U.S.–Soviet space flight, and the last flight of an Apollo spacecraft. Conducted between July 15 and July 24, 1975, the mission entailed the docking of an Apollo and Soyuz spacecraft, which allowed for both joint and separate scientific experiments; this included an engineered eclipse of the Sun by Apollo which allowed Soyuz to take photographs of the solar corona. Subsequent joint space flights included the Shuttle–Mir Program and the International Space Station.

An aerial view of the Temple Mount, one of the most important religious sites in the Old City of Jerusalem. Dominated by three religious structures from the early Umayyad period—the al-Aqsa Mosque, the Dome of the Rock and the Dome of the Chain—the mount also has walls which date to the Herodian dynasty, including the Western Wall.

The Temple Mount is the holiest site in Judaism, in which it is regarded as the place where God's divine presence is manifested most frequently. In Christianity, it is held to have been the location of both Solomon's Temple and the Second Temple. Sunni Muslims consider the Mount the third holiest site in Islam, associating it with Muhammad's journey to Jerusalem and ascent to heaven. Owing to its importance to these religions, claims over the Mount have been heavily contested.Photograph: Andrew Shiva

Vertigo is a 1958 American psychological thriller film directed and produced by Alfred Hitchcock and starring James Stewart, Kim Novak, and Tom Helmore. Based on the 1954 novel D'entre les morts by Boileau-Narcejac, the film follows a former police detective who struggles against his acrophobia (an extreme fear of heights), which causes vertigo (a false sensation of rotation), to follow an acquaintance's wife. Although it received mixed reviews upon release, Vertigo has since been considered one of Hitchcock's best works.Poster: Saul Bass; restoration: Adam Cuerden

A diagram showing the anatomy of a mosquito (sp. Culex restuans) larva. Such larvae have a well-developed head with mouth brushes used for feeding, a large thorax with no legs, and a segmented abdomen. The water-inhabiting larvae breathe through spiracles located on their eighth abdominal segments, or through a siphon, and must come to the surface frequently. Larvae develop through four stages, or instars, after which they metamorphose into pupae. At the end of each instar, the larvae molt, shedding their skins to allow for further growth.Diagram: LadyofHats

Papilio machaon is a butterfly of the family Papilionidae and the type species of the genus Papilio. Despite its common name Old World swallowtail, this species is not restricted to the Old World, as populations can be found in North America.

The butterfly has a strong and fast flight, but frequently pauses to hover over flowering herbs and sip nectar. It frequents alpine meadows and hillsides, and males are fond of congregating near summits to compete for passing females. The species feeds mostly on plants of family Umbelliferae.Photograph: Werner Pichler
