Rings of Saturn
A natural-color mosaic of Cassini narrow-angle camera images of the unilluminated side of Saturn's D, C, B, A and F rings (left to right) taken on May 9, 2007. The rings are lettered in order of discovery. The A and B rings, separated by the Cassini Division, are the densest; together with the C ring, they constitute the planet's main rings. The D ring is classified as a dusty ring, like the E and G rings (not pictured here), because of the tiny size of its particles. The F ring is a dynamic mixture of larger and smaller particles.Photograph: NASA/JPL/Space Science Institute

Jaffa
A view of Jaffa, including the bell tower of St. Peter's Church and the minaret of Al-Bahr Mosque, from the Tel Aviv Promenade. An ancient port city in what is now southern Tel Aviv-Yafo, Jaffa is mentioned in the Bible several times in association with the stories of Solomon, Jonah, and Saint Peter. The town was captured by various groups over several millennia, including Arabs, Crusaders, Egyptians, the Ottoman Empire, the French, and British. During the British Mandate tensions arose between the mostly-Jewish population of Tel Aviv and the mostly-Muslim population of Jaffa, and conflict broke out in the late 1940s when the port town was to be included in the new Israeli state. In 1950, Jaffa was merged into Tel Aviv.Photograph: Andrew Shiva

Nautilus diagram
Anatomical diagram of an adult female chambered nautilus, the best known species of nautilus, a "living fossil" related to the octopuses. The animal has a primitive brain that forms a ring around its oesophagus, has four gills (all other cephalopods have only two), and can only move shell-first (seemingly "backwards") by pumping water out through its funnel. The shell and tentacles are shown here as shadows.Diagram: K.D. Schroeder

Albert Bridge, London
The Albert Bridge is a road bridge over the River Thames in West London, connecting Chelsea on the north bank to Battersea on the south. Designed and built by Rowland Mason Ordish in 1873, it initially operated as a toll bridge but was commercially unsuccessful; the tolls were lifted after six years. The roadway is only 27 feet (8.2 m) wide and the bridge has serious structural weaknesses; it has been reinforced several times but never replaced, despite calls for closure or pedestrianisation.Photograph: David Iliff

This lone nude, unprecedented in Western painting at the time, influenced numerous future artists. The work is now held in the Gemäldegalerie Alte Meister in Dresden, Germany.Painting: Giorgione and Titian

The Lotos-Eaters
"The Lotos-Eaters" is a poem by Alfred Tennyson, 1st Baron Tennyson, published in his 1832 poetry collection. Written after a trip to Spain, it describes a group of mariners who, upon eating the lotos, are put into an altered state and isolated from the outside world. The poem is inspired by a similar scene in Homer's Odyssey. This illustration, completed by W. E. F. Britten for a 1901 printing of Tennyson's works, accompanies the lines:

Let us swear an oath, and keep it with an equal mind,
In the hollow Lotos-land to live and lie reclined
On the hills like Gods together, careless of mankind.

Atmosphere of Jupiter
A 14-frame clip showing the atmosphere of Jupiter as viewed from the NASA probe Cassini. Taken over a span of 24 Jupiter rotations between October 31 and November 9, 2000, this clip shows various patterns of motion across the planet. The Great Red Spot rotates counterclockwise, and the uneven distribution of its high haze is obvious. To the east (right) of the Red Spot, oval storms, like ball bearings, roll over and pass each other. East-west bands adjacent to each other move at different rates. Strings of small storms rotate around northern-hemisphere ovals. The large grayish-blue "hot spots" at the northern edge of the white Equatorial Zone change over time as they proceed eastward across the planet. Ovals in the north rotate counter to those in the south. Small, very bright features appear quickly and randomly in turbulent regions, possibly lightning storms. The smallest visible features at the equator are about 600 km (370 miles) across.Animation: NASA/JPL/University of Arizona

Photograph of glassworkers by Lewis Hine
A baseball team composed mostly of child laborers from an Indiana glassmaking factory, as photographed by Lewis Hine in August 1908. Hine (1874–1940) was an American sociologist who promoted the use of photography as an educational medium and means for social change. Beginning in 1908, he spent ten years photographing child labor for the National Child Labor Committee. The project was a dangerous one, and Hine had to disguise himself – at times as a fire inspector, post card vendor, Bible salesman or industrial photographer – to avoid the factory police and foremen.Photograph: Lewis Hine; restoration: Lise Broer

Armenian Genocide
An Armenian woman kneeling beside a dead child in a field during the Armenian Genocide, conducted by the government of the Ottoman Empire. The genocide is conventionally held to have begun on 24 April 1915, when Ottoman authorities arrested and later executed some 250 Armenian intellectuals and community leaders. Much of the remaining Armenian population were deported into the deserts of Syria, where most died from starvation, exhaustion, and systematic massacres. The total number of people killed has been estimated at between 1 and 1.5 million. Though the events are widely recognized as a genocide by historians, the Turkish government rejects such a description.Photograph: American Committee for Relief in the Near East; restoration: MjolnirPants

HMAS Australia (D84)
HMAS Australia was a County-class heavy cruiser of the Royal Australian Navy. Laid down in Scotland in 1925, the ship entered service in 1928. She served predominantly in the South-West Pacific until the beginning of World War II, when she was tasked to the northern Atlantic. In 1942, Australia was reassigned as flagship of the ANZAC Squadron, where she supported US naval and amphibious operations throughout South-East Asia. A series of kamikaze attacks during the invasion of Lingayen Gulf led to Australia being recalled for repairs in the United Kingdom, where she remained until the end of the war. In her later years, Australia served as part of the British Commonwealth Occupation Force in Japan and as a training ship. She was sold for scrap in 1955.Photo: Allan Green; restoration: Chris Woodrich

Calipers
A diagram of vernier calipers, a device used to measure the distance between two opposite sides of an object, showing the individual parts:
  1. Outside large jaws: used to measure external diameter or width of an object
  2. Inside small jaws: used to measure internal diameter of an object
  3. Depth probe: used to measure depths of an object or a hole
  4. Main scale in centimeters, marked every millimeter
  5. Main scale in inches, marked every 1/16 of an inch
  6. Vernier scale gives interpolated measurements to 1/20 of a millimeter
  7. Vernier scale gives interpolated measurements to 1/128 of an inch
  8. Retainer: used to block movable part to allow the easy transferring of a measurement

Here the metric scale shows a distance of 2.475 cm between the jaw faces: the 0 mark on the vernier is between 2.4 and 2.5, and the 7.5 mark is the one best aligned with a mark on the main scale. Similarly, the inch scale shows (155/8)/16, or 125/128, of an inch.

The Pig-faced Lady of Manchester Square and the Spanish Mule of Madrid
The Pig-faced Lady of Manchester Square and the Spanish Mule of Madrid, an 1815 cartoon print by George Cruikshank depicting a pig-faced woman and contrasting her with the unpopular Ferdinand VII of Spain. At this time, rumours had spread that such a woman was living in fashionable Manchester Square, and various newspapers (such as the Morning Herald and Morning Chronicle) reported this as fact. Eyewitness accounts, marriage proposals, and tales of attacks by the woman further fanned the flames, and the rumour was recollected as fact as late as the 1860s.

Stories of pig-faced women originated in the late 1630s; the last significant work to treat their existence as genuine was published in 1924.Print: George Cruikshank

Homann map
A detailed eighteenth-century map of Scandinavia by J. B. Homann, depicting Denmark, Norway, Sweden, Finland and the Baltic states of Livonia, Latvia and Curlandia. The map notes fortified cities, villages, roads, bridges, forests, castles and topography. The elaborate title cartouche in the upper left quadrant features angels supporting a title curtain and a medallion supporting an alternative title in French, "Les Trois Covronnes du Nord".

Born in 1664, Homann became an engraver and cartographer in the late 17th century, and opened his own publishing house in 1702. In 1715 Emperor Charles VI appointed him Imperial Geographer of the Holy Roman Empire. Homann held the position until his death in 1724.Map: Johann Baptist Homann
