The Annunciation is an oil painting by the Early Netherlandish master Jan van Eyck, painted around 1434–1436. Originally on panel, the work was transferred to canvas in the 19th century. It is thought to have been the left (inner) wing of a triptych, although there have been no sightings of the other wings since before 1817. The painting depicts the biblical scene of the Annunciation, in which the Archangel Gabriel announces to the Virgin Mary that she will bear the son of God. The inscription shows his words: AVE GRA PLENA ('Hail, full of grace'). She modestly draws back and responds, ECCE ANCILLA DNI ('Behold the handmaiden of the Lord'); these words appear upside down. The Annunciation is now in the collection of the National Gallery of Art in Washington, D.C.

Gerty Cori (1896–1957) was a Czech-American biochemist. She was the third woman to win a Nobel Prize in science, and the first woman to be awarded the Nobel Prize in Physiology or Medicine, for her significant role in the "discovery of the course of the catalytic conversion of glycogen". Born in Prague, Cori grew up at a time when women were marginalized in science and allowed few educational opportunities, but she nonetheless gained admittance to medical school. With her husband Carl Ferdinand Cori and the Argentine physiologist Bernardo Houssay, she received the Nobel Prize in 1947. This photograph from the Smithsonian Institution Archives, taken in the same year, shows Cori and her husband working in their laboratory.

The pomelo (Citrus maxima) is the largest citrus fruit from the family Rutaceae and the principal ancestor of the grapefruit. It is a natural, non-hybrid citrus fruit, native to Southeast Asia. Growing on a tree 5–15 meters (16–50 feet) in height, the fruit is 15–25 cm (6–10 in) in diameter with a usual weight of 1–2 kilograms (2–4 pounds) and has a thicker rind than a grapefruit. It is divided into 11 to 18 segments and its flesh tastes like a mild grapefruit, with little of its common bitterness. The fruit generally contains few, relatively large seeds, but some varieties have numerous seeds.

Joseph Fourier (21 March 1768 – 16 May 1830) was a French mathematician and physicist born in Auxerre and best known for initiating the investigation of Fourier series, which eventually developed into Fourier analysis and harmonic analysis, and their applications to problems of heat transfer and vibration. The Fourier transform and Fourier's law of conduction are also named after him. He is also generally credited with the discovery of the greenhouse effect. This engraving of Fourier was drawn by Julien-Léopold Boilly, a French artist noted for his album of lithographs titled Iconographie de l'Institut Royal de France (1820–1821) and his booklet Album de 73 portraits-charge aquarellés des membres de l'Institut (1820), containing watercolor caricatures of seventy-three members of the Institut de France.

The blue-throated macaw (Ara glaucogularis) is a species of macaw that is endemic to a small area of north-central Bolivia, known as the Llanos de Moxos. Recent population and range estimates suggest that about 350 to 400 individuals remain in the wild. Its demise was brought on by nesting competition, avian predation, and a small native range, exacerbated by indigenous hunting and capture for the pet trade. Although plentiful in captivity, it is critically endangered in the wild and protected by trading prohibitions. In 2014, the species was designated a natural patrimony of Bolivia. This blue-throated macaw in flight was photographed at Loro Parque, on the Spanish island of Tenerife in the Canary Islands.

Margaret Harwood (March 19, 1885 – February 6, 1979) was an American astronomer who specialized in photometry, which involved measuring variation in the light of stars and asteroids. In 1916, at 30 years old, Harwood was named director of Maria Mitchell Observatory, and worked there until her retirement in 1957. In 1917, she discovered the asteroid 886 Washingtonia four days before its formal recognition, but was advised not to report it because it would have been inappropriate for a woman to do so. In 1923, she became the first woman to gain access to the Mount Wilson Observatory, and in 1924 was the first woman allowed to use the observatory's 60-inch telescope, the largest in the world at the time. In 1960, an asteroid discovered at Palomar was named in her honor as 7040 Harwood. This photograph of Harwood is in the archives of the Smithsonian Institution.

The saung, also known as the saung-gauk or the Burmese harp, is an arched harp used in traditional Burmese music. It is regarded as the national musical instrument of Myanmar. It was possibly introduced as early as 500 AD from southeastern India, based on archaeological evidence of Burmese temple reliefs that depict a long-necked harp similar to depictions found in Bengal. The earliest evidence of the saung itself is at the Bawbawgyi Pagoda near present-day Prome. At that site, there is a mid-600s sculptured relief depicting the arched harp with about five strings, appearing with musicians and a dancer. It has survived continuously since that time, and has been mentioned in many texts, pictorial representations and Bagan temples. Burmese chronicles describe harps in ceremonial ensembles at medieval Pagan, and female harpists who performed for royals. This 19th-century saung is in the collection of the Metropolitan Museum of Art in New York City.

Agelena labyrinthica is a species of spider in the family Agelenidae. It builds a flat-plate surface web connected to a funnel-shaped retreat similar to a labyrinth, typically between low-lying grass and vegetation. These webs can be at ground level, or up to 1.5 metres (5 ft) from the ground. The species is fairly common in Europe, and is typically concentrated in areas near forests and low-lying vegetation, as well as in dry grassland. This female A. labyrinthica spider was photographed in a funnel web in Blankaart Nature Reserve near Diksmuide, Belgium. She has lost one leg, which is trapped in the web.

Ruth Bader Ginsburg (March 15, 1933 – September 18, 2020) was an American lawyer and jurist who served as an associate justice of the Supreme Court of the United States from 1993 until her death in 2020. She was nominated to the Supreme Court by President Bill Clinton to replace retiring justice Byron White, and at the time was generally viewed as a moderate consensus-builder. She eventually became part of the liberal wing of the Supreme Court as the Court shifted to the right over time. Ginsburg was the first Jewish woman and the second woman to serve on the Supreme Court, after Sandra Day O'Connor. During her tenure, Ginsburg wrote notable majority opinions, including United States v. Virginia (1996), Olmstead v. L.C. (1999), Friends of the Earth, Inc. v. Laidlaw Environmental Services, Inc. (2000), and City of Sherrill v. Oneida Indian Nation of New York (2005). This official photographic portrait of Ginsburg was taken by Supreme Court photographer Steve Petteway in 2016.

Golden Delicious is a cultivar of apple. The cultivar arose from a chance seedling, possibly a hybrid of Grimes Golden and Golden Reinette. The original tree was found on the family farm of J. M. Mullins in Clay County, West Virginia, and was locally known as Mullins' Yellow Seedling. Mullins sold the tree and propagation rights to Stark Brothers Nurseries and Orchards for $5000, which first marketed it as a companion of their Red Delicious in 1914 (although the two cultivars are not closely related). Golden Delicious is one of the fifteen most popular apple cultivars in the United States in 2008, popular for eating as well as in salads, apple sauces, and apple pies. This photograph of one whole and one halved Golden Delicious apple was focus-stacked from six images.

The rhesus macaque (Macaca mulatta), is a species of Old World monkey native to South, Central, and Southeast Asia. It has the widest geographic range of all non-human primates, occupying a great diversity of altitudes and a great variety of habitats, from grasslands to arid and forested areas, but also close to human settlements. Generally brown or grey in colour, it is 47 to 53 cm (19 to 21 in) in length with a 20.7 to 22.9 cm (8.1 to 9.0 in) tail and weighs 5.3 to 7.7 kg (12 to 17 lb). Due to its wide availability and biological similarity to humans, the rhesus macaque has been used extensively in medical and biological research. It has facilitated breakthroughs including vaccines for rabies, smallpox, polio, and antiretroviral medication to treat HIV/AIDS. A rhesus macaque became the first primate astronaut in 1948, but died during the flight, followed on 14 June 1949 by Albert II, who became the first primate and first mammal in space. This male rhesus macaque, of the subspecies M. m. mulatta, was photographed in the Gokarna Forest, Nepal.

Marie Stopes (1880–1958) was a British author, palaeobotanist, and campaigner for eugenics and women's rights. After obtaining a doctorate from the University of Munich, Stopes was appointed to the faculty of the Victoria University of Manchester, becoming its first female academic. She went on to make significant contributions to plant palaeontology and coal classification, assisting the British government with her coal expertise during World War I. From 1913, Stopes began writing on issues of marriage, parenthood and women's reproductive rights. With her second husband, Humphrey Verdon Roe, she founded the first birth control clinic in Britain. Her sex manual Married Love (1918) was controversial and influential, and brought the subject of birth control into wide public discourse. She was also a believer in eugenics, being described in her biography by June Rose as "an elitist, an idealist, interested in creating a society in which only the best and beautiful should survive". This 1904 photograph shows Stopes at work in her laboratory in Manchester.

The Hayden Bridge is a wrought-iron truss bridge that was manufactured by the Phoenixville Bridge Works in the U.S. state of Pennsylvania. It was built in 1882 and was initially located near Corinne, Utah, crossing the Bear River as part of the first transcontinental railroad. In 1901, the bridge was moved more than 1,000 miles (1,600 km) and reassembled at its present location, crossing the McKenzie River in Springfield, Oregon, where it serves as part of the Marcola line for the distribution of lumber. It later closed down due to the closure of the area's lumbermills, until it was converted into a pedestrian bridge in 2019. It is the oldest intact bridge in the state of Oregon. This photograph of the Hayden Bridge was taken as part of a 1990 Historic American Engineering Record survey.

The Woman Suffrage Procession was a suffragist parade held in Washington, D.C., on March 3, 1913, the day before Woodrow Wilson's first presidential inauguration. It was organized by Alice Paul for the National American Woman Suffrage Association. Thousands of suffragists marched down Pennsylvania Avenue "in a spirit of protest against the present political organization of society, from which women are excluded". The march and the attention it attracted were important in advancing women's suffrage in the United States. This image shows the front cover of the official program of the Woman Suffrage Procession, illustrated by Benjamin Moran Dale. It depicts an elaborately dressed woman blowing a trumpet with a "Votes for Women" banner while riding on horseback in front of the United States Capitol.

The Port Hills are a range of hills in the Canterbury Region of New Zealand, so named because they lie between the city of Christchurch and its port at Lyttelton. The hills are an eroded remnant of the Lyttelton volcano, which erupted millions of years ago. Starting at Godley Head, the range runs approximately east–west along the northern side of Lyttelton Harbour and thence to the south, terminating near Gebbies Pass above the head of the harbour. It includes a number of summits between 300 and 500 metres (980 and 1,640 feet) above sea level. This photograph shows a panoramic view of the Port Hills from Mount Ada, looking towards Lyttelton Harbour in the distance.

Katherine Johnson (1918–2020) was an African-American mathematician whose calculations of orbital mechanics as a NASA employee were critical to the success of U.S. crewed spaceflights. During her 33-year career at NASA and its predecessor, the National Advisory Committee for Aeronautics, she earned a reputation for mastering complex manual calculations and helped the space agency pioneer the use of computers to perform tasks. She worked with the Apollo program, calculating rendezvous paths for the lunar lander and command module on its flights to the Moon. Johnson's calculations were essential to the beginning of the Space Shuttle program and she also worked on plans for a mission to Mars. In 2015, President Barack Obama awarded her the Presidential Medal of Freedom, as a pioneering example of African-American women in STEM. She was portrayed by Taraji P. Henson as a lead character in the 2016 film Hidden Figures. This NASA photographic portrait of Johnson was taken in 1983.

The blue-billed duck (Oxyura australis) is a small Australian stiff-tailed duck, with both the male and female growing to a length of 40 centimetres (16 in). The male has a slate-blue bill which changes to bright-blue during the breeding season, which gives the duck its common name. The male has deep chestnut plumage during breeding season, reverting to a dark grey. The female retains black plumage with brown tips all year round. The duck is endemic to Australia's temperate regions, inhabiting natural inland wetlands and also artificial wetlands, such as sewage ponds, in large numbers. It can be difficult to observe due to its cryptic nature during its breeding season through autumn and winter. The male duck exhibits a complex mating ritual. The species is omnivorous, with a preference for small aquatic invertebrates. This male blue-billed duck was photographed near Penrith, New South Wales, in 2020.

Harriet Jacobs (1813 or 1815 – 1897) was an African-American writer who was born into slavery in Edenton, North Carolina. During her teenage years, seeking protection from sexual harassment by her enslaver James Norcom, she began a relationship with the white lawyer Samuel Sawyer, who became the father of her children Joseph and Louisa Matilda. When Norcom threatened to sell her children if she did not submit to his desire, Jacobs escaped and hid in a tiny crawl space under the roof of her grandmother's house, so low that she could not stand up in it. After staying there for seven years, she finally managed to escape to the free North, where she was reunited with her children. In 1861, she published an autobiography titled Incidents in the Life of a Slave Girl under the pseudonym Linda Brent, a book which was later described by her biographer Jean Fagan Yellin as an "American classic". This portrait of Jacobs, her only known formal photograph, was taken in 1894 by Gilbert Studios in Washington, D.C.
