The construction of Mount Rushmore, a United States National Monument depicting the heads of four U.S. Presidents carved into the Black Hills of South Dakota, began on August 10, 1927, with the bust of George Washington. This first phase was completed in seven years (partial completion in 1932 shown here), culminating in its unveiling in 1934. The remaining three heads—Thomas Jefferson, Abraham Lincoln, and Theodore Roosevelt—took only an additional seven years to complete.

An animated image showing the apparent retrograde motion of Mars in 2003 as seen from Earth. All the true planets appear to periodically switch direction as they cross the sky. Because Earth completes its orbit in a shorter period of time than the planets outside its orbit, we periodically overtake them, like a faster car on a multi-lane highway. When this occurs, the planet will first appear to stop its eastward drift, and then drift back toward the west. Then, as Earth swings past the planet in its orbit, it appears to resume its normal motion west to east.

An illustration from the first edition of The Wonderful Wizard of Oz, depicting the scene where Dorothy meets the Cowardly Lion, the first time the four major characters of the novel come together. The book was originally published in 1900 and has since been reprinted countless times, most often under the name The Wizard of Oz, which is the name of both the 1902 Broadway musical and the extremely popular, highly acclaimed 1939 film version. Thanks in part to the film it is one of the best-known stories in American popular culture and has been widely translated. Its initial success, and the success of the popular 1902 musical Baum adapted from his story, led to his writing and having published thirteen more Oz books.

The frontispiece to Gustave Doré's illustrated edition of the Bible. Based on the story of Noah's Ark, this illustration shows humans and a tiger who, unable to board the Ark, are doomed by the flood that was sent by God to destroy all life, futilely attempting to save their children and cubs. The biblical story of Noah is contained in the Book of Genesis, chapters 6–9, wherein God tells Noah to build a large vessel to save his family and a representation of the world's animals before He destroys the world. Although traditionally accepted as historical, by the 19th century the discoveries of archaeologists and biblical scholars had led most people to abandon a literal interpretation of the Ark story.

An adult male chicken, the rooster is distinguished from the hen by the prominent fleshy crest on its head called a comb and hanging flaps of skin on either side under its beak called wattles. Both the adult male and female have wattles and combs, but in most breeds these are more prominent in males, an example of sexual dimorphism.

Early Autumn (13th century), a well-known example of bird-and-flower painting, a style of Chinese painting where the subject is traditionally described to be "flowers, birds, fish and insects", which in reality allows the artist to deal with a wide range of natural topics. In this painting, the depiction of decaying lotus leaves and dragonflies hovering over stagnant water is likely a veiled criticism of Mongol rule.

Phobos, the larger and closer of the two moons of Mars, as seen from about 6,000 kilometres (3,700 mi) away. A small, irregularly shaped object, Phobos orbits about 9,377 km (5,827 mi) from the center of Mars, closer to its primary than any other planetary moon. The illuminated part of Phobos seen in the images is about 21 km (13 mi) across. The most prominent feature in the images is the large crater Stickney in the lower right. With a diameter of 9 km (5.6 mi), it is the largest feature on Phobos.

American troops in an M8 Greyhound passing the Arc de Triomphe during a parade celebrating the liberation of Paris, which concluded 65 years ago today. Paris had been administered by Nazi Germany since the Second Compiègne armistice in June 1940 when Germany occupied the North and West of France and when the Vichy puppet regime was established with its capital in the central city of Vichy. This battle marked the end of Operation Overlord, the restoration of the French Republic and the exile of the Vichy government to Sigmaringen in Germany.

A sketch of the original Waldorf-Astoria Hotel, a luxury hotel in New York City, done in charcoal and pastel on brown paper by Joseph Pennell, ca. 1904–1908. It started as two hotels: one owned by William Waldorf Astor, whose 13-story Waldorf Hotel was opened in 1893, located on the current site of the Empire State Building, and the other owned by his cousin, John Jacob Astor IV, called the Astoria Hotel and opened four years later in 1897, four stories higher. Initially foreseen as two separate entities, founding proprietor George Boldt planned the new structure so it could be connected to the old, and the combined hotel became the largest in the world at the time. The Waldorf-Astoria relocated to its present location in 1931.

A White-faced Heron (Egretta novaehollandiae) in breeding plumage searching for trapped bait fish at low tide. It is a common bird throughout most of Australasia, relatively small for a heron, ranging from 60–70 centimetres (24–28 in) in height. The White-faced heron uses a variety of techniques to find food including standing still and waiting for prey movement, walking slowly in shallow water, wing flicking, foot raking or even chasing prey with open wings, generally feeding solitarily or independently in small groups.

A seventeenth century drawing of a camera obscura, an optical device whose invention eventually led to photography. Light from a scene enters through a hole in side of a room, as depicted here in a cutaway view (a box may be used, such as with a pinhole camera), and strikes a surface where it is reproduced, in color, and upside-down.
